The objectives are for the natural resources that form the basis of our existence on this planet to be used sparingly and in a manner that takes the requirements of both nature and humanity into account. You too can help to protect the environment by operating your vehicle in an environmentally responsible manner. Fuel consumption and the rate of engine, transmission, brake and tire wear are affected by these factors: Roperating conditions of your vehicle Ryour personal driving style You can influence both factors. You should bear the following in mind: Operating conditions: Ravoid short trips as these increase fuel con- sumption. make sure that the tire pressures are correct. Rdo not carry any unnecessary weight. Rremove roof racks once you no longer need them. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Ralways have service work carried out at a qualified specialist workshop. Personal driving style: Ralways Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine when the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. frequent, sudden acceleration and braking. Ravoid Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. off the engine in stationary traffic. Rkeep an eye on the vehicle's fuel consumption. Rswitch Environmental concerns and recommendations Wherever the operating instructions require you to dispose of materials, first try to regenerate or re-use them. Observe the relevant environmental rules and regulations when disposing of materials. In this way you will help to protect the environment.

In the event of an accident, rescue services can use the QR code to quickly find the appropriate rescue card for your vehicle. The current rescue card contains the most important information about your vehicle in a compact form, e.g. the routing of the electric cables. You can find more information under http:// portal.aftersales.i.daimler.com/public/ content/asportal/en/communication/ informationen_fuer/QRCode.html. Data stored in the vehicle Data recording This vehicle is capable of recording diagnostic information relating to vehicle operation, malfunctions, and user settings. This may include information about the performance or status of various systems, including but not limited to, engine, throttle, steering or brake systems, that is stored and can be read out with suitable devices, particularly when the vehicle is serviced. The data obtained is used to properly diagnose and service your vehicle or to further optimize and develop vehicle functions. COMAND/mbrace If the vehicle is equipped with COMAND or mbrace, additional data about the vehicle’s operation, the use of the vehicle in certain situations, and the location of the vehicle may be compiled through COMAND or the mbrace system. For additional information please refer to the COMAND User Manual and/or the mbrace Terms and Conditions. Event data recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record data that will assist in understanding how a vehicle’s systems performed in certain crash or near crash-like situations, such as during air bag deployment or when hitting a road obstacle. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: Rhow various systems in your vehicle are operating Rwhether or not the driver and passenger seat belts are fastened Rhow far (if at all) the driver is depressing the accelerator and/or brake pedal and Rhow fast the vehicle is traveling This data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, can combine the EDR data with the type of personal identification data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties that have the special equipment, such as law enforcement, can read the information by accessing the vehicle or the EDR. EDR data may be used in civil and criminal matters as a tool in accident reconstruction, accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC Z 31 32 Introduction ("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel. MBUSA will not share EDR data with others without the consent of the vehicle owners or, if the vehicle is leased, without the consent of the lessee. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law. Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the Restraint System Module and other systems. State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of February 2013, 13 states have enacted laws relating to EDRs.

Panic alarm Occupant safety Introduction to the restraint system The restraint system can reduce the risk of vehicle occupants coming into contact with parts of the vehicle's interior in the event of an accident. The restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. The restraint system comprises: RSeat belt system bags RChild restraint system RChild seat securing systems The components of the restraint system work in conjunction with each other. They can only deploy their protective function if, at all times, all vehicle occupants: RAir Rhave To activate: press the ! button : for approximately one second. A visual and audible alarm is triggered if the alarm system is armed. X To deactivate: press the ! button : again. or X Insert the SmartKey into the ignition lock. or, on vehicles with KEYLESS GO: X Press the Start/Stop button. The SmartKey must be in the vehicle. X fastened their seat belts correctly (Y page 47) Rhave adjusted their seat and head restraint properly (Y page 105). As the driver, you also have to make sure that the steering wheel is adjusted correctly. Observe the information relating to the correct driver's seat position (Y page 104). You also have to make sure that an air bag can inflate properly if deployed (Y page 50). An air bag supplements a correctly worn seat belt. As an additional safety device, the air bag increases the level of protection for vehicle occupants in the event of an accident. For example, if, in the event of an accident, the protection offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only the air bags that increase protection in that particular accident situation are deployed. However, seat belts and air bags generally do not protect against objects penetrating the vehicle from the outside. Information on restraint system operation can be found under "Triggering of the Emergency Tensioning Devices and air bags" (Y page 59). For more information about children traveling with you in the vehicle and on child restraint systems, see "Children in the vehicle" (Y page 64). Important safety notes G WARNING Modifications to the restraint system may cause it to no longer work as intended. The restraint system may then not perform its intended protective function and may fail in an accident or trigger unexpectedly, for example. This poses an increased risk of injury or even fatal injury. Never modify parts of the restraint system. Never tamper with the wiring, the electronic components or their software. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for further information contact our Customer Assistance Center at 1-800-FOR-MERCedes (1 800 367 6372). Restraint system warning lamp The functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time. The 6 restraint system warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up after the ignition is switched on Rdoes not go out after a few seconds with the engine running Rlights up again while the engine is running G WARNING If restraint system is malfunctioning, restraint system components may be triggered unintentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. This can affect the Emergency Tensioning Device or air bag, for example. This poses an increased risk of injury or even fatal injury. Have the restraint system checked and repaired in a qualified specialist workshop as soon as possible. PASSENGER AIR BAG OFF indicator lamp PASSENGER AIR BAG OFF indicator lamp : is part of the Occupant Classification System (OCS). The PASSENGER AIR BAG OFF indicator lamp informs you about the status of the frontpassenger front air bag. If the PASSENGER AIR BAG OFF indicator lamp: Ris lit: the front-passenger front air bag is deactivated. It will then not be deployed in the event of an accident. Rdoes not light up: the front-passenger front air bag is enabled. If, in the event of an accident, all deployment criteria are met, the front-passenger front air bag is deployed. Z 45 Safety Occupant safety 46 Occupant safety Safety Depending on the person in the frontpassenger seat, the front-passenger front air bag must either be deactivated or enabled; see the following points. You must make sure of this both before and during a journey. RChildren in a child restraint system: whether the front-passenger front air bag is enabled or deactivated depends on the installed child restraint system, and the age and size of the child. Therefore, be sure to observe the notes on the "Occupant Classification System (OCS)" (Y page 53) and on "Children in the vehicle" (Y page 64). There you will also find instructions on rearward and forward-facing child restraint systems on the front-passenger seat. RAll other persons: depending on the classification of the person in the frontpassenger seat, the front-passenger front air bag is enabled or deactivated (Y page 53). Be sure to observe the notes on "Seat belts“ (Y page 46) and "Air bags" (Y page 50). There you can also find information on the correct seat position. Seat belts Introduction Seat belts are the most effective means of restricting the movement of vehicle occupants in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior or being ejected from the vehicle. Furthermore, the seat belt helps to keep the vehicle occupant in the best position in relation to the air bag. The seat belt system comprises: RSeat belts REmergency Tensioning Devices for the front seat belts and the outer seat belts in the rear RSeat belt force limiters for the front seat belts and the outer seat belts in the rear If the seat belt is pulled out of the belt outlet quickly or with a jerky movement, the belt retractor locks. The belt strap cannot be extracted any further. The Emergency Tensioning Device tightens the seat belt in an accident, pulling the belt close against the body. However it does not pull the vehicle occupant back in the direction of the backrest. The Emergency Tensioning Device does not correct an incorrect seat position or the routing of an incorrectly fastened seat belt. When triggered, a seat belt force limiter helps to reduce the force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags, which absorb part of the deceleration force. This can reduce the force exerted on the vehicle occupants during an accident. ! If the front-passenger seat is not occupied, do not engage the seat belt tongue in the buckle on the front-passenger seat. Otherwise, in the event of an accident, the Emergency Tensioning Device and frontpassenger front air bag may be triggered and would need to be replaced. Important safety notes The use of seat belts and child restraint systems is required by law in: Rall 50 states U.S. territories Rthe District of Columbia Rall Canadian provinces Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey. Rthe G WARNING If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for example, in an accident, during braking or when abruptly changing direc- tion. This poses an increased risk of injury or even fatal injury. Make sure that all vehicle occupants are seated properly with a correctly fastened seat belt. G WARNING The seat belt does not offer the intended level of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdomen or neck injuries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always ensure that the backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the center of your shoulder. G WARNING Persons under 5 ft (1.50 m) in height cannot fasten the seat belt correctly without an additional suitable restraint system. If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for example, in an accident, during braking or an abrupt change of direction. This poses an increased risk of injury or even fatal injury. For this reason, always secure persons under 5 ft (1.50 m) in height in suitable restraint systems. If a child younger than twelve years old and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for this Mercedes-Benz vehicle. The child restraint system must be appropriate to the age, weight and size of the child Ralways observe the instructions and safety notes in the "Children in the vehicle" section of this Operator's Manual (Y page 64) in addition to the child restraint system manufacturer's installation instructions Rbe sure to observe the instructions and safety notes on the "Occupant classification system (OCS)" (Y page 53) G WARNING The seat belts may not perform their intended protective function if: Rthey are damaged, modified, extremely dirty, bleach or dyed Rthe seat belt buckle is damaged or extremely dirty Rthe Emergency Tensioning Devices, belt anchorages or inertia reels have been modified Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modified or damaged seat belts may tear or fail, e.g. in an accident. Modified Emergency Tensioning Devices could accidentally trigger or fail to deploy when necessary. This poses an increased risk of injury or even fatal injury. Never modify the seat belts, Emergency Tensioning Devices, belt anchorages or inertia reels. Make sure that the seat belts are undamaged, not worn out and clean. Following an accident, have the seat belts checked immediately at a qualified specialist workshop. Only use seat belts that have been approved for your vehicle by Mercedes-Benz. Proper use of the seat belts Observe the safety notes on the seat belt (Y page 46). All vehicle occupants must be wearing the seat belt correctly before beginning the journey. Also make sure that all vehicle occupants are always wearing the seat belt correctly while the vehicle is in motion. Z 47 Safety Occupant safety 48 Occupant safety When fastening the seat belt, always make sure that: Safety Rthe seat belt tongue is only inserted to the belt buckle belonging to that seat. Rthe seat belt is tight across your body. Avoid wearing bulky clothing, e.g. a winter coat. Rthe seat belt is not twisted. Only then can the forces which occur be distributed over the area of the belt. Rthe shoulder section of the belt is always routed across the center of your shoulder. The shoulder section of the belt must not come into contact with your neck or be routed under your arm. Where possible, adjust the seat belt to the appropriate height. Rthe lap belt passes tightly and as low down as possible across your lap. The lap belt must always be routed across your hip joints and not across your abdomen. This applies particularly to pregnant women. If necessary, push the lap belt down to your hip joint and pull it tight using the shoulder section of the belt. Rthe seat belt is not routed across sharp, pointed or fragile objects. If you have such items located on or in your clothing, e.g. pens, keys or eyeglasses, store these in a suitable place. Ronly one person is using a seat belt at a time. Infants and children must never travel sitting on the lap of a vehicle occupant. In the event of an accident, they could be crushed between the vehicle occupant and seat belt. Robjects are never secured with a seat belt if the seat belt is also being used by one of the vehicle's occupants. Also ensure that there are never objects between a person and the seat, e.g. cushions. Seat belts are only intended to secure and restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects, luggage or loads (Y page 222). Fastening and adjusting the seat belts Observe the safety notes on the seat belt (Y page 46) and the notes on correct use of seat belts (Y page 47). Basic illustration Adjust the seat (Y page 104).

Seat belt adjustment All seat belts except the driver's seat belt are equipped with a special seat belt retractor to securely fasten child restraint systems in the vehicle. Further information can be found under "Special seat belt retractor" (Y page 64). The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. This function adjusts the driver's and frontpassenger seat belt to the upper body of the occupants. The belt strap is tightened slightly when: X Releasing seat belts ! Make sure that the seat belt is fully rolled up. Otherwise, the seat belt or belt tongue will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Damaged seat belts can no longer fulfill their protective function and must be replaced. Visit a qualified specialist workshop.

Belt warning for the driver and front passenger The 7 seat belt warning lamp in the instrument cluster is a reminder that all vehicle occupants must wear their seat belts. It may Z Safety 50 Occupant safety light up continuously or flash. In addition, there may be a warning tone. Regardless of whether the driver's seat belt has already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. If, after six seconds, the driver or front-passenger seat belt has not been fastened and the doors are closed, the 7 seat belt warning lamp lights up. As soon as the driver's and frontpassenger seat belts are fastened or a front door is opened again, the 7 seat belt warning lamp goes out. If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. This warning tone stops after six seconds or when the driver's seat belt is fastened. If the vehicle's speed exceeds 15 mph (25 km/h) once and the driver's and frontpassenger seat belts are not fastened, a warning tone sounds. A warning tone also sounds with increasing intensity for 60 seconds or until the driver or front passenger have fastened their seat belts. If the driver or front passenger unfasten their seat belts during the journey, the seat belt warning is activated again. i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belts" (Y page 186). Air bags Introduction The installation point of an air bag can be recognized by the AIR BAG symbol. An air bag complements the correctly fastened seat belt. It is no substitute for the seat belt. The air bag provides additional protection in applicable accident situations. Not all air bags are deployed in an accident. The different air bag systems function independently from one another (Y page 59). However, no system available today can completely eliminate injuries and fatalities. It is also not possible to rule out a risk of injury caused by an air bag due to the high speed at which the air bag must be deployed. Important safety notes G WARNING If you do not sit in the correct seat position, the air bag cannot protect as intended and could even cause additional injury when deployed. This poses an increased risk of injury or even fatal injury. To avoid hazardous situations, always make sure that all of the vehicle's occupants: Rhave fastened their seat belts correctly, including pregnant women Rare sitting correctly and maintain the greatest possible distance to the air bags Rfollow the following instructions Always make sure that there are no objects between the air bag and the vehicle's occupants. RAdjust the seats properly before beginning your journey. Always make sure that the seat is in an almost upright position. The center of the head restraint must support the head at about eye level. RMove the driver's and front-passenger seats as far back as possible. The driver's seat position must allow the vehicle to be driven safely. ROnly hold the steering wheel on the outside. This allows the air bag to be fully deployed. RAlways lean against the backrest while driving. Do not lean forwards or lean against the door or side window. You may otherwise be in the deployment area of the air bags. RAlways keep your feet in the footwell in front of the seat. Do not put your feet on the dashboard, for example. Your feet may oth- erwise be in the deployment area of the air bag. RFor this reason, always secure persons less than 5 ft (1.50 m) tall in suitable restraint systems. Up to this height, the seat belt cannot be worn correctly. If a child is traveling in your vehicle, also observe the following notes: RAlways secure children under twelve years of age and less than 5 ft (1.50 m) tall in suitable child restraint systems. RChild restraint systems should be installed on the rear seats. ROnly secure a child in a rearward-facing child restraint system on the frontpassenger seat when the front-passenger front air bag is deactivated. If the PASSENGER AIR BAG OFF indicator lamp is permanently lit, the front-passenger front air bag is deactivated (Y page 45). RAlways observe the instructions and safety notes on the "Occupant Classification System (OCS)" (Y page 53) and on "Children in the vehicle" (Y page 64) in addition to the child restraint system manufacturer's installation instructions. Objects in the vehicle interior may prevent an air bag from functioning correctly. Before starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make sure that: are no people, animals or objects between the vehicle occupants and an air bag. Rthere are no objects between the seat, door and B-pillar. Rno hard objects, e.g. coat hangers, hang on the grab handles or coat hooks. Rno accessories, such as cup holders, are attached to the vehicle within the deployment area of an air bag, e.g. to doors, side windows, rear side trim or side walls. Rno heavy, sharp-edged or fragile objects are in the pockets of your clothing. Store such objects in a suitable place. G WARNING If you modify the air bag cover or affix objects such as stickers to it, the air bag can no longer function correctly. There is an increased risk of injury. Never modify an air bag cover or affix objects to it. G WARNING Sensors to control the air bags are located in the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the function of the sensors being impaired. The air bags might therefore not function properly anymore. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. There is an increased risk of injury. Never modify the doors or parts of the doors. Always have work on the doors or door paneling carried out at a qualified specialist workshop. Front air bags Rthere Driver's air bag : deploys in front of the steering wheel. Front-passenger front air bag ; deploys in front of and above the glove box. When deployed, the front air bags offer additional head and thorax protection for the occupants in the front seats. The PASSENGER AIR BAG OFF indicator lamp informs you about the status of the frontpassenger front air bag (Y page 45). Z 51 Safety Occupant safety 52 Occupant safety The front-passenger front air bag will only deploy if: Safety Rthe system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied (Y page 53) Rthe PASSENGER AIR BAG OFF indicator lamp is not lit (Y page 54) Rthe restraint system control unit predicts a high accident severity Knee bags Front side impact air bags : and rear side impact air bags ; deploy next to the outer bolster of the seat backrest. When deployed, the side impact air bag offers additional thorax protection. However, it does not protect the: Rhead Rneck Rarms Driver's knee bag : deploys under the steering column and front-passenger knee bag ; under the glove box. The driver's and frontpassenger knee bags are triggered together with the front air bags. The driver's and front-passenger knee bags offer additional thigh, knee and lower leg protection for the occupants in the front seats. Side impact air bags G WARNING Unsuitable seat covers could restrict or even prevent the deployment of the air bags integrated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the function of the Occupant Classification System (OCS) could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. In the event of a side impact, the side impact air bag is deployed on the side on which the impact occurs. The side impact air bag on the frontpassenger side (front) deploys under the following conditions: Rthe OCS system detects that the frontpassenger seat is occupied or Rthe belt tongue is engaged in the belt buckle of the front-passenger seat If the belt tongue is engaged in the belt buckle, the side impact air bag on the frontpassenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the frontpassenger seat is occupied or not. Pelvis air bags G WARNING Unsuitable seat covers could restrict or even prevent the deployment of the air bags integrated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the function of the Occupant Classification System Occupant safety Pelvis air bags : deploy below next to the outer seat cushions. When activated, the pelvis air bag enhances the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs. The pelvis air bag is deployed on the side of the impact. The pelvis air bag on the front-passenger side does not deploy under the following conditions: ROCS has detected that the front-passenger seat is unoccupied. front-passenger seat belt is not fastened. If the belt tongue is engaged in the belt buckle, the pelvis air bag on the frontpassenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the frontpassenger seat is occupied or not. Rthe Window curtain air bags Safety (OCS) could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. 53 Window curtain air bags : are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. When deployed, the window curtain air bag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the window curtain air bag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a window curtain air bag may be deployed in other accident situations (Y page 59). Occupant Classification System (OCS) Introduction The Occupant Classification System (OCS) categorizes the person in the front-passenger seat. Depending on that result, the frontpassenger front air bag and front-passenger knee bag are either enabled or deactivated. The system does not deactivate: Rthe side impact air bag Rthe pelvis air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices Z 54 Occupant safety Prerequisites To be classified correctly, the front passenger must sit: Occupant Classification System operation (OCS) Safety Rwith the seat belt fastened correctly an almost upright position with their back against the seat backrest Rwith their feet resting on the floor, if possible If the front passenger does not observe these conditions, OCS may produce a false classification, e.g. because the front passenger: Rin Rtransfers their weight by supporting themselves on a vehicle armrest Rsits in such a way that their weight is raised from the seat cushion If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to observe the correct positioning of the child restraint system. Never place objects under or behind the child restraint system, e.g. cushions. The entire base of the child restraint system must always rest on the seat cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat as possible against the backrest of the front-passenger seat. The child restraint system must not touch the roof or be subjected to a load by the head restraint. Adjust the angle of the seat backrest and the head restraint position accordingly. Only then can OCS be guaranteed to function correctly. Always observe the child restraint system manufacturer's installation instructions. PASSENGER AIR BAG OFF indicator lamp : shows you whether the front-passenger front air bag is deactivated. X Turn the SmartKey to position 1 or 2 in the ignition lock or on vehicles with KEYLESSGO, press the Start/Stop button once or twice. The system carries out self-diagnostics. The PASSENGER AIR BAG OFF indicator lamp must light up for approximately six seconds. The PASSENGER AIR BAG OFF indicator lamp then displays the status of the frontpassenger front air bag. If the status of the front-passenger front air bag changes while the vehicle is in motion, an air bag display message may appear in the instrument cluster (Y page 181). When the front-passenger seat is occupied, always pay attention to the PASSENGER AIR BAG OFF indicator lamp. Be aware of the status of the front-passenger front air bag both before and during the journey. If the PASSENGER AIR BAG OFF indicator lamp: Ris lit: the front-passenger front air bag is deactivated. It will then not be deployed in the event of an accident. Rdoes not light up: the front-passenger front air bag is enabled. If, in the event of an accident, all deployment criteria are met, the front-passenger front air bag is deployed. G WARNING If the PASSENGER AIR BAG OFF indicator lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident and cannot perform its intended protective function. A person in the frontpassenger seat could then, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the frontpassenger front air bag is enabled or disabled in accordance with the person in the front-passenger seat Rthe front-passenger seat has been moved back as far back as possible. Rthe person is seated correctly. Make sure, both before and during the journey, that the status of the front-passenger front air bag is correct. G WARNING If you secure a child in a child restraint system on the front-passenger seat and the PASSENGER AIR BAG OFF indicator lamp is off, the front-passenger front air bag can deploy in the event of an accident. The child could be struck by the air bag. This poses an increased risk of injury or even fatal injury. Make sure that the front-passenger front air bag has been disabled. The PASSENGER AIR BAG OFF indicator lamp must be lit. G WARNING If you secure a child in a forward-facing child restraint system on the front-passenger seat and you position the front-passenger seat too close to the dashboard, the child could, in the event of an accident: Rcome into contact with the vehicle's interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example Rbe struck by the air bag if the PASSENGER AIR BAG OFF indicator lamp is off This poses an increased risk of injury or even fatal injury. Move the front-passenger seat as far back as possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle belt sash guide to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the vehicle belt sash guide. If necessary, adjust the vehicle belt sash guide and the front-passenger seat accordingly. Always observe the child restraint system manufacturer's installation instructions. If OCS determines that: Rthe front-passenger seat is unoccupied, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the frontpassenger front air bag is deactivated. Rthe front-passenger seat is occupied by a child of up to twelve months old, in a standard child restraint system, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the front-passenger front air bag is deactivated. But even in the case of a twelve-month-old child, in a standard child restraint system, the PASSENGER AIR BAG OFF indicator lamp can go out after the system self-test. This indicates that the front-passenger front air bag is activated. The result of the classification is dependent on, among other factors, the child restraint system Z 55 Safety Occupant safety Safety 56 Occupant safety and the child's stature. It is recommended that you install the child restraint system on a suitable rear seat. Rthe front-passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), the PASSENGER AIR BAG OFF indicator lamp lights up and remains lit after the system self-test depending on the result of the classification or, alternatively, goes out. - If the PASSENGER AIR BAG OFF indicator lamp is off, move the front-passenger seat as far back as possible. Alternatively, a person of smaller stature can sit on a rear seat. - If the PASSENGER AIR BAG OFF indicator lamp is lit, a person of smaller stature should not use the front-passenger seat. Rthe front-passenger seat is occupied by an adult or a person of a stature corresponding to that of an adult, the PASSENGER AIR BAG OFF indicator lamp goes out after the system self-test. This indicates that the front-passenger front air bag is activated. If children are traveling in the vehicle, be sure to observe the notes on "Children in the vehicle" (Y page 64). When OCS is malfunctioning, the red 6 restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The front-passenger front air bag is deactivated in this case and does not deploy during an accident. Have the system checked by qualified technicians as soon as possible. Consult an authorized Mercedes-Benz Center. The front-passenger seat should only be repaired at an authorized Mercedes-Benz Center. If the front-passenger seat, the seat cover or the seat cushion is damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center. For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The Occupant Classification System (OCS) categorizes the occupant in the front-passenger seat. Depending on that result, the front-passenger front air bag is either enabled or deactivated. System self-test G DANGER If the PASSENGER AIR BAG OFF indicator lamp does not light up during the system selftest, then the system is malfunctioning. The front-passenger front air bag might be triggered unintentionally or might not be triggered at all in the event of an accident with high deceleration. This poses an increased risk of injury or even fatal injury. In this case the front-passenger seat may not be used. Do not install a child restraint system on the front-passenger seat. Have the Occupant Classification System (OCS) checked and repaired immediately at a qualified specialist workshop. G DANGER If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident. In this case, the front-passenger front air bag cannot perform its intended protective function, e.g. when a person is seated in the frontpassenger seat. That person could, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury.

Do not install a child restraint system on the frontpassenger seat. Have the Occupant Classification System (OCS) checked and repaired immediately at a qualified specialist workshop. 57 G WARNING Objects between the seat surface and the child restraint system could affect OCS operation. This could result in the front-passenger air bag not functioning as intended during an accident. This poses an increased risk of injury or even fatal injury. Do not place any objects between the seat surface and the child restraint system. The entire base of the child restraint system must always rest on the seat cushion of the frontpassenger seat. The backrest of the forwardfacing child restraint system must, as far as possible, be resting on the backrest of the front-passenger seat. Always comply with the child restraint system manufacturer's installation instructions.

There is a risk of injury. Do not touch the air bag parts. Have a deployed air bag replaced at a qualified specialist workshop as soon as possible. G WARNING A deployed air bag no longer offers any protection and cannot provide the intended protection in an accident. There is an increased risk of injury. Have the vehicle towed to a qualified specialist workshop in order to have a deployed air bag replaced. It is important for your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags continue to perform their protective function for the vehicle occupants in the event of a crash. G WARNING Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer operational and are unable to perform their intended protective function. This poses an increased risk of injury or even fatal injury. Therefore, have pyrotechnic Emergency Tensioning Devices which have been triggered immediately replaced at a qualified specialist workshop. An electric motor is used by PRE-SAFE® to trigger the tightening of the seat belt in hazardous situations. This procedure is reversible. If Emergency Tensioning Devices are triggered or air bags are deployed, you will hear a bang, and a small amount of powder may also be released. The 6 restraint system warning lamp lights up. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard, but it may cause short-term breathing difficulties in people with asthma or other respiratory problems. To avoid this, you may wish to get out of the vehicle or open the windows as soon as it is safe to do so. Air bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the environment. National guidelines must be observed during disposal. In California, see www.dtsc.ca.gov/ HazardousWaste/Perchlorate/ index.cfm. Method of operation During the first stage of a collision, the restraint system control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the restraint system control unit triggers the Emergency Tensioning Devices during a frontal or rear collision. An Emergency Tensioning Device can only be triggered, if: Rthe ignition is switched on Rthe components of the restraint system are operational; see "Restraint system warning lamp" (Y page 45) Rthe belt tongue is engaged in the buckle on the respective front-passenger seat The Emergency Tensioning Devices in the rear compartment are triggered independently of the lock status of the seat belts. If the restraint system control unit detects a more severe accident, further components of Z 59 Safety Occupant safety Safety 60 Occupant safety the restraint system are activated independently of each other in certain frontal collision situations: RFront air bags and driver's knee bag RWindow curtain air bag, if the system determines that deployment can offer additional protection to that provided by the seat belt The front-passenger front air bag is activated or deactivated depending on the person on the front-passenger seat. The frontpassenger front air bag can only deploy in an accident if the PASSENGER AIR BAG OFF indicator lamp is off. Observe the information on the PASSENGER AIR BAG OFF indicator lamp (Y page 45). Your vehicle has two-stage front air bags. During the first deployment stage, the front air bag is filled with propellant gas to reduce the risk of injuries. The front air bag is fully deployed with the maximum amount of propellant gas if a second deployment threshold is reached within a few milliseconds. The activation threshold of the Emergency Tensioning Devices and the air bag are determined by evaluating the rate of vehicle deceleration or acceleration which occurs at various points in the vehicle. This process is preemptive in nature. Deployment should take place in good time at the start of the collision. The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by: Rthe distribution of forces during the collision Rthe collision angle Rthe deformation characteristics of the vehicle Rthe characteristics of the object with which the vehicle has collided Factors which can only be seen and measured after a collision has occurred do not play a decisive role in the deployment of an air bag. Nor do they provide an indication of air bag deployment. The vehicle can be deformed considerably, without an air bag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of deceleration is not high. Conversely, air bags may be deployed even though the vehicle suffers only minor deformation. This is the case if, for example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs as a result. If the restraint system control unit detects a side impact or if the vehicle rolls over, the applicable components of the restraint system are activated independently of each other depending on the apparent type of accident. RSide impact air bags and pelvis air bag on the side of impact, independently of the Emergency Tensioning Device and the use of the seat belt on the driver's seat and outer seats in the second row - the OCS system detects that the frontpassenger seat is occupied or - the belt tongue is engaged in the belt buckle of the front-passenger seat RWindow curtain air bag on the side of impact, independently of the use of the seat belt and independently of whether the front-passenger seat is occupied REmergency Tensioning Devices, if the system determines that deployment can offer additional protection in this situation RWindow curtain air bags on the driver's and front-passenger side in certain situations when the vehicle rolls over, if the system determines that deployment can offer additional protection to that provided by the seat belt i Not all air bags are deployed in an accident.

PRE-SAFE® PLUS (anticipatory occupant protection system PLUS) Introduction PRE-SAFE® PLUS is only available in vehicles with the Driving Assistance package. Using the radar sensor system, PRE-SAFE® PLUS is able to detect that a head-on or rearend collision is imminent. In certain hazardous situations, PRE-SAFE® PLUS takes preemptive measures to protect the vehicle occupants. Important safety notes PRE-SAFE® The intervention of PLUS cannot prevent an imminent collision. The driver is not warned about the intervention of PRE-SAFE® PLUS. PRE-SAFE® PLUS does not intervene if the vehicle is backing up. When driving, or when parking or exiting a parking space with assistance from Active Parking Assist, PRE-SAFE® PLUS will not apply the brakes. Function PRE-SAFE® PLUS intervenes in certain situations if the radar sensor system detects an imminent head-on or rear-end collision. PRE-SAFE® PLUS takes the following measures depending on the hazardous situation detected: Rif the radar sensor system detects that a head-on collision is imminent, the seat belts are pre-tensioned. Rif the radar sensor system detects that a rear-end collision is imminent: - the brake pressure is increased if the driver applies the brakes when the vehicle is stationary. - the seat belts are pre-tensioned. The PRE-SAFE® PLUS braking application is canceled: Rif the accelerator pedal is depressed when a gear is engaged Rif the risk of a collision passes or is no longer detected Rif DISTRONIC PLUS indicates an intention to pull away If the hazardous situation passes without resulting in an accident, the original settings are restored. Automatic measures after an accident Immediately after an accident, the following measures are implemented, depending on the type and severity of the impact: Rthe hazard warning lamps are activated emergency lighting is activated Rthe vehicle doors are unlocked Rthe front side windows are lowered Rthe Z Safety Rif 63 64 Children in the vehicle Safety Rvehicles with a memory function: the electrically adjustable steering wheel is raised Rthe engine is switched off and the fuel supply is cut off Rvehicles with mbrace: automatic emergency call Children in the vehicle Important safety notes Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Children are generally better protected there. If a child younger than twelve years old and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for Mercedes-Benz vehicles. The child restraint system must be appropriate to the age, weight and size of the child Rbe sure to observe the instructions and safety notes in this section in addition to the child restraint system manufacturer's installation instructions Rbe sure to observe the instructions and safety notes on the "Occupant Classification System (OCS)" (Y page 53) G WARNING If you leave children unsupervised in the vehicle, they could set it in motion by, for example: Rrelease the parking brake. the automatic transmission out of the parking position P.

Driving safety systems Overview of driving safety systems In this section, you will find information about the following driving safety systems: (Anti-lock Braking System) (Y page 70) RBAS (Brake Assist System) (Y page 71) RBAS PLUS (Brake Assist System PLUS) with Cross-Traffic Assist (Y page 71) RCOLLISION PREVENTION ASSIST PLUS (distance warning function and Adaptive Brake Assist) (Y page 73) RESP® (Electronic Stability Program) (Y page 76) REBD (Electronic Brake force Distribution) (Y page 79) RADAPTIVE BRAKE (Y page 79) RPRE-SAFE® Brake (Y page 80) RABS Important safety notes If you fail to adapt your driving style or if you are inattentive, the driving safety systems can neither reduce the risk of an accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for maintaining the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 264). In wintry driving conditions, always use winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible. ABS (Anti-lock Braking System) General information ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. The ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. ABS works from a speed of about 5 mph (8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. Important safety notes i Observe the "Important safety notes" section (Y page 70). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop. When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 189) and display messages which may be shown in the instrument cluster (Y page 176). Braking If ABS intervenes: continue to depress the brake pedal vigorously until the braking situation is over. X To make a full brake application: depress the brake pedal with full force. X If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. BAS (Brake Assist System) General information BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. Important safety notes i Observe the "Important safety notes" section (Y page 70). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking. Braking X Keep the brake pedal firmly depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist PLUS) with Cross-Traffic Assist General information BAS PLUS can help you to minimize the risk of a collision with a vehicle or a pedestrian and reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking. i Pay attention to the important safety notes in the "Driving safety systems" section (Y page 70). BAS PLUS is only available on vehicles with the Driving Assistance package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a camera system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an extended period of time Rthat cross the path of your vehicle In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians by using typical characteristics such as the body contours and posture of a person standing upright. Z 71 Safety Driving safety systems Safety 72 Driving safety systems If the radar sensor system or the camera system is malfunctioning, BAS PLUS functions are restricted or no longer available. The brake system is still available with complete brake boosting effect and BAS. Recognition by the radar sensor system is also impaired in the event of: i Observe the restrictions described in the "Important safety notes" section“ (Y page 72). Rthere Rthere is dirt on the sensors or anything else covering the sensors Rthere is interference by other radar sources BAS PLUS cannot always clearly identify objects and complex traffic situations. In such cases, BAS PLUS may: are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rvehicles quickly moving into the radar sensor system detection range Recognition by the camera system is also impaired in the event of: Rintervene Rdirt Important safety notes G WARNING unnecessarily Rnot intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. G WARNING BAS PLUS cannot always clearly identify people, this is especially the case if they are moving. BAS PLUS cannot intervene in these cases. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. G WARNING BAS PLUS does not react: Rto small people, e.g. children animals Rto oncoming vehicles Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto In the event of snowfall or heavy rain, the recognition can be impaired. on the camera or if the camera is covered Rthere is glare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif: - pedestrians move quickly, e.g. into the path of the vehicle - the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects - a pedestrian is concealed by other objects - the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera system checked at a qualified specialist workshop. Driving safety systems To avoid a collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and RBAS PLUS has detected a risk of collision When driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possible moment. When driving at a speed above 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traffic situation. BAS PLUS provides braking assistance in hazardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and 155 mph (250 km/h). Up to a speed of approximately 44 mph (70 km/h), BAS PLUS may react to: Rstationary objects in the path of your vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robjects crossing your path and that are recognized in the detection range of the sensors i If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. BAS PLUS is deactivated and the brakes function as usual, if: Ryou release the brake pedal. Rthere is no longer a risk of collision. Rno obstacle is detected in front of your vehicle. Ryou depress the accelerator pedal. Ryou activate kickdown. COLLISION PREVENTION ASSIST PLUS General information COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autonomous braking function and adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If COLLISION PREVENTION ASSIST PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. If you do not react to the visual and audible collision warning, autonomous braking can be initiated in critical situations. If you apply the brake yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake Assist assists you. Activating or deactivating COLLISION PREVENTION ASSIST PLUS is activated after every ignition cycle. You can activate or deactivate COLLISION PREVENTION ASSIST PLUS in the on-board computer (Y page 174). When deactivated, the distance warning function and the autonomous braking function are also deactivated. If COLLISION PREVENTION ASSIST PLUS is deactivated, the æ symbol appears in the assistance graphics display. Important safety notes In particular, the detection of obstacles can be impaired if: Rthere is dirt on the sensors or anything else covering the sensors is snow or heavy rain Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Rthere Z Safety Function 73 74 Driving safety systems Safety Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rnew vehicles or after a service on the COLLISION PREVENTION ASSIST PLUS system Observe the notes in the section on breaking-in (Y page 126). Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Distance warning function General information The distance warning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically. Important safety notes i Observe the "Important safety notes" section for driving safety systems (Y page 70). G WARNING The distance warning function does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. In such cases, the distance warning function may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay careful attention to the traffic situation and do not rely solely on the distance warning function. Rnot Function Starting at a speed of around 4 mph (7 km/h), the distance warning function warns you if you rapidly approach a vehicle in front. An intermittent warning tone will then sound, and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action, provided it is safe to do so. Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the system to display a warning. With the help of the radar sensor system, the distance warning function can detect obstacles that are in the path of your vehicle for an extended period of time. Up to a speed of around 44 mph (70 km/h), the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles. Autonomous braking function If the driver does not react to the distance warning signal in a critical situation, COLLISION PREVENTION ASSIST PLUS can assist with the autonomous braking function. The autonomous braking function: Rgives the driver more time to react to critical driving situations Rcan help the driver to avoid an accident or Rreduces the effects of an accident The autonomous braking function is available in the following speed ranges: Rfrom 4 mph (7 km/h) to approx. 65 mph (105 km/h) for moving objects Rfrom 4 mph (7 km/h) to approx. 31 mph (50 km/h) for stationary objects If the autonomous braking function requires a particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. Adaptive Brake Assist i Observe the "Important safety notes" section (Y page 70). Adaptive Brake Assist provides braking assistance in hazardous situations at speeds above 4 mph (7 km/h). It uses radar sensor technology to assess the traffic situation. G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In such cases, Adaptive Brake Assist can: Rintervene unnecessarily intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. Rnot G WARNING Adaptive Brake Assist does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering As a result, the Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause Brake Assist to intervene. If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. With the help of adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of collision with the vehicle in front, it calculates the braking force necessary to avoid a collision. If you apply the brakes forcefully, adaptive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal. Rthere is no longer any danger of a collision. Rno obstacle is detected in front of your vehicle. Adaptive Brake Assist is then deactivated. If adaptive Brake Assist demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. Up to a speed of approximately 155 mph (250 km/h), adaptive Brake Assist is capable of reacting to moving objects that have already been detected as such at least once over the period of observation. Up to a speed of approximately 44 mph (70 km/h), adaptive Brake Assist reacts to stationary obstacles. Z 75 Safety Driving safety systems 76 Driving safety systems ESP® (Electronic Stability Program) Safety General notes i Observe the "Important safety notes" section (Y page 70). ESP® monitors driving stability and traction, i.e. power transmission between the tires and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking. ETS/4ETS (Electronic Traction System) i Observe the "Important safety notes" section (Y page 70). ETS traction control is part of ESP®. On vehicles with 4MATIC, 4ETS is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is transferred to the wheel or wheels with traction. Traction control remains active, even if you deactivate ESP®.

Z Safety If you deactivate ESP®: 79 80 Driving safety systems PRE-SAFE® Brake Safety General information PRE-SAFE® Brake can help you to minimize the risk of a collision with a vehicle ahead or a pedestrian, and reduce the effects of such a collision. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. i Pay attention to the important safety notes in the "Driving safety systems" section (Y page 70). PRE SAFE® Brake is only available in vehicles with the Driving Assistance Plus package. For PRE-SAFE® Brake to assist you when driving, the radar sensor system and the camera system must be switched on and be operational. With the help of the radar sensor system and the camera system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. In addition, pedestrians in the path of your vehicle can be detected. PRE-SAFE® Brake detects pedestrians using typical characteristics such as the body contours and posture of a person standing upright. i Observe the restrictions described in the "Important safety notes" section“ (Y page 80). Important safety notes G WARNING PRE-SAFE® Brake will initially brake your vehi- cle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you brake yourself. Even after subsequent full application of the brakes a collision cannot always be avoided, particularly when approaching at too high a speed. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action, provided it is safe to do so. In the event of a partial application of the brakes, the vehicle is braked with up to 50% of the full braking pressure. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then brake the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation. G WARNING PRE-SAFE® Brake cannot always clearly identify people, especially if they are moving. In these cases, PRE-SAFE® Brake cannot intervene. There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. G WARNING PRE-SAFE® Brake does not react: Rto small people, e.g. children animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering Rto As a result, PRE-SAFE® Brake may neither give warnings nor intervene in all critical situations. There is a risk of an accident. Driving safety systems In the event of snowfall or heavy rain, the recognition can be impaired. Recognition by the radar sensor system is also impaired in the event of: Rthere is dirt on the sensors or anything else covering the sensors Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line relative to the center of your vehicle Recognition by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is covered Rthere is glare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif: - pedestrians move quickly, e.g. into the path of the vehicle - the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects - a pedestrian is concealed by other objects - the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera system checked at a qualified specialist workshop. Function X To activate/deactivate: activate or deactivate PRE-SAFE® Brake in the on-board computer (Y page 174). If the PRE-SAFE® Brake is not activated, the æ symbol appears in the multifunction display.

The windows could otherwise fog up. To prevent the windows from fogging up: Rswitch Rswitch briefly off climate control only briefly on air-recirculation mode only Rswitch on the cooling with air dehumidification function Rswitch on the defrost windshield function briefly, if required Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control can only be operated when the engine is running. Optimum operation is only achieved with the side windows and roof closed. The residual heat function can only be activated or deactivated if the ignition is switched off (see the Digital Operator's Manual, keyword "Residual heat"). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (see the Digital Operator's Manual, keyword "Convenience opening"). This will speed up the cooling process and the desired interior temperature will be reached more quickly. i The integrated filter filters out most particles of dust and soot and completely filters out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Maintenance Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet. Overview of climate control systems 119 Canada only : Sets the temperature, left ; Defrosts the windshield = Switches the ZONE function on/off ?

Notes on breaking-in a new vehicle Important safety notes The sensor system of some driving and driving safety systems adjusts automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in procedure. New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. RDo not manually shift to a lower gear to brake the vehicle. RTry to avoid depressing the accelerator pedal beyond the point of resistance (kickdown). Additional breaking-in notes Mercedes-AMG vehicles: RDo not drive faster than 85 mph (140 km/h) for the first 1,000 miles (1,500 km). ROnly allow the engine to reach a maximum engine speed of 4,500 rpm briefly. RChange gear in good time. After 1000 miles (1500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced. Always observe the respective maximum permissible speed.

Further information on driving safety systems (Y page 70). Cruise Control General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must shift to a lower gear in time. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 20 mph (30 km/h). Important safety notes If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. Cruise control cannot take into account the road, traffic and weather conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. Do not use cruise control: Rin road and traffic conditions which do not allow you to maintain a constant speed, e.g. in heavy traffic or on winding roads Ron slippery road surfaces. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow If there is a change of drivers, advise the new driver of the speed stored. G WARNING If you call up the stored speed and it differs from the current speed, the vehicle accelerates or decelerates. If you do not know the stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an accident. Pay attention to the road and traffic conditions before calling up the stored speed. If you do not know the stored speed, store the desired speed again. Z Driving and parking around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind. 141 142 Driving systems Driving and parking Cruise control lever : ; = ?

Vehicles are detected with the aid of the radar sensor system. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. Change into a lower gear in good time on long and steep downhill gradients. This is especially important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. DISTRONIC PLUS cannot prevent a collision without your intervention. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately in order to increase the distance to the vehicle in front or take evasive action provided it is safe to do so. For DISTRONIC PLUS to assist you when driving, the radar sensor system must be switched on and operational; see "Radar sensor system" in the index. DISTRONIC PLUS operates in range between 0 mph (0 km/h) and 120 mph (200 km/h). Do not use DISTRONIC PLUS while driving on roads with steep gradients.

Important safety notes G WARNING DISTRONIC PLUS does not react to: Rpeople or animals Rstationary obstacles on the road, e.g. stop- ped or parked vehicles and crossing traffic As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Roncoming G WARNING DISTRONIC PLUS cannot always clearly identify other road users and complex traffic situations. In such cases, DISTRONIC PLUS may: Rgive an unnecessary warning and then brake the vehicle Rneither give a warning nor intervene Raccelerate or brake unexpectedly There is a risk of an accident. Continue to drive carefully and be ready to brake, in particular when warned to do so by DISTRONIC PLUS. G WARNING DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration. If this braking force is insufficient, DISTRONIC PLUS warns you visually and audibly. There is a risk of an accident. In such cases, apply the brakes yourself and try to take evasive action. ! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automatically in certain situations. To prevent damage to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in the following or other similar situations: Rwhen Rin towing the vehicle the car wash If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of accident nor override the laws of physics. DISTRONIC PLUS cannot take into account the road, traffic and weather conditions. DISTRONIC PLUS is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. Do not use DISTRONIC PLUS: Rin road and traffic conditions which do not allow you to maintain a constant speed, e.g. in heavy traffic or on winding roads Ron slippery road surfaces. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. In particular, the detection of obstacles can be impaired if: Rthere is dirt on the sensors or anything else covering the sensors is snow or heavy rain Rthere is interference by other radar sources Rthere are strong radar reflections, for example, in parking garages If DISTRONIC PLUS no longer detects a vehicle in front, DISTRONIC PLUS may unexpectedly accelerate the vehicle to the stored speed.

If you do not know the Driving systems Briefly pull the cruise control lever towards you ?. X Remove your foot from the accelerator pedal. DISTRONIC PLUS is activated. The first time it is activated, the current speed is stored. Otherwise, it sets the vehicle cruise speed to the previously stored value. X Driving with DISTRONIC PLUS Pulling away and driving X If you want to pull away with DISTRONIC PLUS: remove your foot from the brake pedal. X Briefly pull the cruise control lever towards you =. or X Accelerate briefly. Your vehicle pulls away and adapts its speed to that of the vehicle in front. If no vehicle is detected in front, your vehicle accelerates to the set speed. i The vehicle can also pull away when it is facing an unidentified obstacle or is driving on a different line from another vehicle. The vehicle then brakes automatically. There is a risk of an accident. Be ready to brake at all times. If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained. If DISTRONIC PLUS detects a faster-moving vehicle in front, it increases the driving speed. However, the vehicle is only accelerated up to the speed you have stored. Selecting the drive program DISTRONIC PLUS supports a sporty driving style when you have selected the S or M (AMG vehicles: S, S+ or M) driving program (Y page 133). Acceleration behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have selected the E (AMG vehicles: C) driving program, the vehicle accelerates more gently. This setting is recommended in stop-and-start traffic. Changing lanes If you change to the passing lane, DISTRONIC PLUS supports you when: Ryou are driving faster than 45 mph (70 km/h) RDISTRONIC PLUS is maintaining the distance to a vehicle in front Ryou switch on the appropriate turn signal RDISTRONIC PLUS does not detect a danger of collision If these conditions are fulfilled, your vehicle is accelerated. Acceleration will be interrupted if changing lanes takes too long or if the distance between your vehicle and the vehicle in front becomes too small. i When changing lanes, DISTRONIC PLUS monitors the left lane on left-hand drive vehicles and the right lane on right-hand drive vehicles. Stopping G WARNING When leaving the vehicle, even if it is braked only by DISTRONIC PLUS, it could roll away if: Rthere is a malfunction in the system or in the voltage supply. RDISTRONIC PLUS has been deactivated with the cruise control lever, e.g. by a vehicle occupant or from outside the vehicle. Z Driving and parking stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an accident. Pay attention to the road and traffic conditions before calling up the stored speed. If you do not know the stored speed, store the desired speed again. 145 146 Driving systems Driving and parking Rthe electrical system in the engine compartment, the battery or the fuses have been tampered with. Rthe battery is disconnected. Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant. There is a risk of an accident. If you wish to exit the vehicle, always turn off DISTRONIC PLUS and secure the vehicle against rolling away. For further information on deactivating DISTRONIC PLUS (Y page 146). If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. Once your vehicle is stationary, it remains stationary and you do not need to depress the brake. Depending on the specified minimum distance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. When DISTRONIC PLUS is activated, the transmission is shifted automatically to position P if: Rthe driver's door is open and the driver's seat belt is unfastened. Rthe engine is switched off, unless it is automatically switched off by the ECO start/ stop function. Ra system malfunction occurs. Rthe power supply is not sufficient.

RESP® Driving systems General notes Pay particular attention in the following traffic situations: DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short. Other vehicles changing lanes Driving and parking Tips for driving with DISTRONIC PLUS RCornering, going into and coming out of a bend RVehicles traveling on a different line ROther vehicles changing lanes RNarrow vehicles RObstructions and stationary vehicles RCrossing vehicles In such situations, brake if necessary. DISTRONIC PLUS is then deactivated. Cornering, going into and coming out of a bend DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late. Vehicles traveling on a different line 147 DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short. Z 148 Driving systems Obstructions and stationary vehicles DISTRONIC PLUS with Steering Assist and Stop&Go Pilot Driving and parking General notes DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Crossing vehicles DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot aids you in keeping the vehicle in the center of the driving lane by means of moderate steering interventions in the speed range from 0 - 125 mph (0 - 200 km/h). It monitors the area in front of your vehicle by means of multifunction camera :, at the top of the windshield. At speeds of 0 - 37 mph (0 - 60 km/h), Stop&Go Pilot focuses on the vehicle in front, taking into account lane markings, e.g. when following vehicles in a traffic jam. At speeds of more than 37 mph (60 km/h) Steering Assist focuses on detected lane markings (left and right), and only on the vehicle in front if lane markings are missing. If these conditions are not present, Steering Assist and Stop&Go Pilot cannot provide assistance. DISTRONIC PLUS must be active in order for the function to be available. Important safety notes If you fail to adapt your driving style, DISTRONIC PLUS with Steering Assist and Stop&Go Pilot can neither reduce the risk of an accident nor override the laws of physics. It cannot take account of road, weather and traffic conditions. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot is only an aid.

DISTRONIC PLUS Steering Assist does not provide assistance: Ron very sharp corners a loss of tire pressure or a defective tire has been detected and displayed Pay attention also to the important safety notes for DISTRONIC PLUS (Y page 143). The steering interventions are carried out with a limited steering moment. The system requires the driver to keep his hands on the steering wheel and to steer himself. If you do not steer yourself or if you take your hands off the steering wheel for a prolonged period of time, the system will first alert you with a visual warning. A steering wheel symbol appears in the multifunction display. If you have still not started to steer and have not taken hold of the steering wheel after five seconds at the latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Assist and Stop&Go Pilot are switched to passive. DISTRONIC PLUS remains active. Rwhen Z Driving and parking braking in good time and for staying in your lane. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot does not detect road and traffic conditions. If you are following a vehicle which is driving towards the edge of the road, your vehicle could come into contact with the curb or other road boundaries. Be particularly aware of other road users, e.g. cyclists, that are directly next to your vehicle. Obstacles such as building site huts on the lane or projecting out into the lane are not detected. An inappropriate steering intervention, e.g. after intentionally driving over a lane marking, can be corrected at any time if you steer slightly in the opposite direction. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane.

PARKTRONIC Important safety notes PARKTRONIC is an electronic parking aid with ultrasonic sensors. It monitors the area around your vehicle using six sensors in the front bumper and six sensors in the rear bumper. PARKTRONIC indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. When maneuvering, parking or pulling out of a parking space, make sure that there are no persons, animals or objects in the area in which you are maneuvering. ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and other objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain.

ATTENTION ASSIST General notes ATTENTION ASSIST helps you during long, monotonous journeys, such as on highways. It is active in the 37 mph (60 km/h) to 125 mph (200 km/h) range. If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break. Important safety notes ATTENTION ASSIST is only an aid. It might not always recognize fatigue or increasing inattentiveness in time or fail to recognize them at all. The system is not a substitute for a wellrested and attentive driver. The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the length of the journey is less than approximately 30 minutes Rif the road condition is poor, e.g. if the surface is uneven or if there are potholes Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration Rif you are predominantly driving at a speed below 37 mph (60 km/h) or above 124 mph (200 km/h) Driving systems Steering Assist activated Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed The attention level evaluation is deleted and restarts when the journey is continued, if: Ryou switch off the engine Ryou take off your seat belt and open the driver's door, e.g. for a change of drivers or to take a break Displaying the attention level You can have current status information displayed in the assistance menu (Y page 174) of the on-board computer. X Select the Assistance display for ATTENTION ASSIST using the on-board computer (Y page 174). The following information is displayed: Rlength of the journey since the last break. attention level determined by ATTENTION ASSIST, displayed in a bar display in five levels from high to low. Rif ATTENTION ASSIST is unable to calculate the attention level and cannot output a warning, the System Suspended message appears. The bar display then changes the display, e.g. if you are driving at a speed below 37 mph (60 km/h) or above 124 mph (200 km/h). Rthe Activating ATTENTION ASSIST X Activate ATTENTION ASSIST using the onboard computer (Y page 174). The system determines the attention level of the driver depending on the setting selected: Standard selected: the sensitivity with which the system determines the attention level is set to normal. Sensitive selected: the sensitivity is set higher. The attention level detected by Attention Assist is adapted accordingly and the driver is warned earlier. When ATTENTION ASSIST is deactivated, the À symbol and OFF appear in the multifunction display in the assistance display when the engine is running. When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine has been stopped. The sensitivity selected corresponds to the last selection activated (standard/sensitive). Warning in the multifunction display If fatigue or increasing lapses in concentration are detected, a warning appears in the multifunction display: Attention Assist: Take a Break! In addition to the message shown in the multifunction display, you will then hear a warning tone. X If necessary, take a break. X Confirm the message by pressing the a button on the steering wheel. On long journeys, take regular breaks in good time to allow yourself to rest. If you do not take a break, you will be warned again after 15 minutes at the earliest. This will only happen if ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. Vehicles with COMAND: if a warning is issued in the multifunction display, a service station search is performed in COMAND. You Z Driving and parking Rif you are driving with the DISTRONIC PLUS 161 162 Driving systems Driving and parking can select a service station and navigation to this service station will then begin. This function can be activated and deactivated in COMAND. Traffic Sign Assist General notes Traffic Sign Assist displays the maximum speed permitted to the driver in the instrument cluster. The data stored in the navigation system and general traffic regulations are used to determine the current speed limit. As Traffic Sign Assist is a map-based system, traffic signs put up temporarily (e.g. near roadworks) are not detected. If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits is updated. Traffic signs with a restriction indicated by an additional sign (e.g. in wet conditions) are also shown. The traffic signs are only displayed with the restrictions if: regulation must be observed with the restriction, or RTraffic Sign Assist is unable to determine whether the restriction applies If Traffic Sign Assist is unable to determine a maximum permitted speed from any of the available sources, no speed limit is displayed in the instrument cluster either. Important safety notes Traffic Sign Assist is only an aid and is not always able to correctly display speed limits. Traffic signs always have priority over the Traffic Sign Assist display. The system may be either functionally impaired or temporarily unavailable if the information in the digital street map of the navigation system is incorrect or out of date. Instrument cluster display Displaying the assistance graphic Call up the assistance graphics display function using the on-board computer (Y page 174). X Select the Traffic Sign Assist display. Detected traffic signs are displayed in the instrument cluster. X Speed limit with unknown restriction Rthe Traffic Sign Assist is not available in all countries. In this case, symbol : is shown in the assistance graphic display (Y page 174). : Maximum permitted speed ; Maximum permitted speed for vehicles for which the restriction in the additional sign is relevant = Additional sign for unknown restriction A maximum permitted speed of 100 mph (100 km/h) and a speed limit of 80 km/h (80 mph) apply with an unknown restriction. Speed limits in wet conditions : Maximum permitted speed ; Additional signs for wet conditions A maximum permitted speed of 80 mph (80 km/h) applies in wet conditions and if Traffic Sign Assist has determined that the restriction must be observed. Canceling the speed limit The speed limit no longer applies :. i The unit for the speed limit (km/h or mph) depends on the country in which you are driving. It is generally neither shown on the traffic sign nor on the instrument cluster but must be taken into account when observing the maximum permitted speed. Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 163) and Lane Keeping Assist (Y page 165). Blind Spot Assist General notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from a speed of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lanes, you will also receive an optical and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. Important safety notes G WARNING Blind Spot Assist does not react to: Rvehicles overtaken too closely on the side, placing them in the blind spot area Rvehicles which approach with a large speed differential and overtake your vehicle As a result, Blind Spot Assist may not give warnings in such situations. There is a risk of an accident. Always observe the traffic conditions carefully, and maintain a safe lateral distance. Blind Spot Assist is only an aid. It may fail to detect some vehicles and is no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles. i USA only: This device has been approved by the FCC as a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar system only. Removing, tampering with, or altering the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user’s authority to operate the equipment.

Blind Spot Assist may otherwise not work properly. Indicator and warning display : Indicator lamp (yellow) Warning lamp (red) If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles driving at the inner edge of their lanes. Due to the nature of the system: Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders. Rthe warning is canceled when driving for an extended period next to long vehicles, such as trucks. The two radar sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors. The sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated. When Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the blind spot monitoring range at speeds above 20 mph (30 km/h), warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator or warning lamps is adjusted automatically according to the ambient light. Driving systems RCollision warning RSwitching on Blind Spot Assist Lane Keeping Assist General notes Lane Keeping Assist monitors the area in front of your vehicle with camera :, which is mounted at the top of the windshield. Active Lane Keeping Assist detects lane markings on the road and can warn you before you leave your lane unintentionally. This function is available in the range between 40 mph and 120 mph (60 km/h and 200 km/h). A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. Important safety notes G WARNING Lane Keeping Assist may not always clearly recognize lane markings. In this case, Lane Keeping Assist may: Rgive an unnecessary warning give a warning There is a risk of an accident. Rnot Always pay particular attention to the traffic situation and stay in lane, in particular if warned by Lane Keeping Assist. G WARNING The Lane Keeping Assist warning does not return the vehicle to the original lane. There is a risk of an accident. You should always steer, brake or accelerate yourself, in particular if warned by Lane Keeping Assist. If you fail to adapt your driving style, Lane Keeping Assist can neither reduce the risk of an accident nor override the laws of physics. Lane Keeping Assist cannot take into account the road, traffic and weather conditions. Lane Keeping Assist is merely an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. The Lane Keeping Assist does not keep the vehicle in the lane. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflections (e.g. when the road surface is wet) Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rthere are no, several or unclear lane markings for a lane, e.g. in areas with road construction work Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Z Driving and parking Information in the Digital Operator's Manual In the Digital Operator's Manual you can find information about: 165 166 Driving systems Rthe road is narrow and winding are strong shadows cast on the road Driving and parking Rthere Switching on Lane Keeping Assist You can find information about this in the Digital Operator's Manual. Active Driving Assistance package General notes The Active Driving Assistance package consists of DISTRONIC PLUS (Y page 142), Active Blind Spot Assist (Y page 166) and Active Lane Keeping Assist (Y page 168). Active Blind Spot Assist General notes Active Blind Spot Assist uses a radar sensor system, pointed toward the rear of the vehicle, to monitor the area to the sides of the vehicle which the driver is unable to see. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lanes, you will also receive a visual and audible collision warning. If a risk of lateral collision is detected, corrective braking may help you avoid a collision. Before a course-correcting brake application, Active Blind Spot Assist evaluates the space in the direction of travel and at the sides of the vehicle. For this, Active Blind Spot Assist uses the forward-facing radar sensors. Active Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h). Important safety notes Active Blind Spot Assist is only an aid and is not a substitute for attentive driving. G WARNING Active Blind Spot Assist does not react to: Rvehicles overtaken too closely on the side, placing them in the blind spot area Rvehicles which approach with a large speed differential and overtake your vehicle As a result, Active Blind Spot Assist may neither give warnings nor intervene in such situations. There is a risk of an accident.

You then hear a double warning tone and red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Course-correcting brake application If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is meant to assist you in avoiding a collision. G WARNING A course-correcting brake application cannot always prevent a collision. There is a risk of an accident. Always steer, brake or accelerate yourself, especially if Active Blind Spot Assist warns you or makes a course-correcting brake application. Always maintain a safe distance at the sides. In very rare cases, the system may make an inappropriate brake application. An inappropriate course-correcting brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate, for example. The course-correcting brake application is available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h). Either no braking application, or a coursecorrecting brake application adapted to the driving situation occurs if: Rthere are vehicles or obstacles, e.g. crash barriers, located on both sides of your vehicle.

You could also lose control of the vehicle. There is a risk of an accident. Only operate the equipment when the traffic situation permits. If you are not sure that this is possible, park the vehicle paying attention to traffic conditions and operate the equipment when the vehicle is stationary. You must observe the legal requirements for the country in which you are currently driving when operating Audio 20/COMAND. Audio 20/COMAND calculates the route to the destination without taking account of the following, for example: Rtraffic lights and yield signs Rmerging lanes Rparking or stopping in a no parking/no stopping zone Rother road and traffic rules and regulations Rnarrow bridges Audio 20/COMAND can give incorrect navigation commands if the actual street/traffic situation does not correspond with the digital map's data. Digital maps do not cover all areas nor all routes in an area. For example, a route may have been diverted or the direction of a one-way street may have changed. For this reason, you must always observe road and traffic rules and regulations during your journey. Road and traffic rules and regulations always have priority over the system's driving recommendations. Navigation announcements are intended to direct you while driving without diverting your attention from the road and driving. Please always use this feature instead of consulting the map display for directions. Looking at the icons or map display can distract you from traffic conditions and driving, and increase the risk of an accident.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions. i Read the information on qualified specialist workshops (Y page 29). Stowage areas Loading guidelines G WARNING If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip over or be flung around and thereby hit vehicle occupants. There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction. Always store objects so that they cannot be flung around. Secure objects, luggage or loads against slipping or tipping before the journey. G WARNING Combustion engines emit poisonous exhaust gases such as carbon monoxide. Exhaust gases can enter the vehicle interior if the trunk lid is open when the engine is running, especially if the vehicle is in motion. There is a risk of poisoning. Always switch off the engine before opening the trunk lid. Never drive with the trunk lid open. G WARNING The exhaust tail pipe and tail pipe trim can become very hot. If you come into contact with these parts of the vehicle, you could burn yourself. There is a risk of injury. Always be particularly careful around the exhaust tail pipe and the tail pipe trim. Allow these components to cool down before touching them. The handling characteristics of a laden vehicle are dependent on the distribution of the load within the vehicle. For this reason, you should observe the following notes when transporting a load: RNever exceed the maximum permissible gross vehicle mass or the gross axle weight rating for the vehicle (including occupants). The values are specified on the vehicle identification plate on the B-pillar of the driver's door. RThe trunk is the preferred place to carry objects. RPosition heavy loads as far forwards as possible and as low down in the trunk as possible. RThe load must not protrude above the upper edge of the seat backrests. RAlways place the load against the rear or front seat backrests. Make sure that the seat backrests are securely locked into place. RAlways place the load behind unoccupied seats if possible. RUse the cargo tie-down rings and the parcel nets to transport loads and luggage. RUse cargo tie-down rings and fastening materials appropriate for the weight and size of the load. RSecure the load with sufficiently strong and wear-resistant tie-downs. Pad sharp edges for protection.

Tires with run-flat characteristics: Rpay attention to the information and warning notices on MOExtended tires (tires with run-flat characteristics). Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety. Before purchasing and using non-approved accessories, visit a qualified specialist workshop and ask about: Rsuitability Rlegal Important safety notes Wheels and tires G WARNING If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an accident. Always replace wheels and tires with those that fulfill the specifications of the original part. When replacing wheels, make sure to use the correct: Rdesignation Rmodel When replacing tires, make sure to use the correct: Rdesignation Rmanufacturer Rmodel G WARNING A flat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident. Tires without run-flat characteristics: Rdo not drive with a flat tire. replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop. Rimmediately stipulations recommendations Information on the sizes and types of wheels and tires for your vehicle can be found under "Wheel/tire combinations" (Y page 291). Information on tire pressure can be found: Rfactory Ron the vehicle's Tire and Loading Information placard on the B-pillar (Y page 275) Ron the tire pressure label on the fuel filler flap (Y page 136) Runder "Tire pressure" (Y page 267) Operation Information on driving Check the tire pressure when the vehicle is heavily laden and adjust prior to a trip. While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop. When parking your vehicle, make sure that the tires do not get deformed by the curb or Operation Regular checking of wheels and tires G WARNING Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately. Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as: Rcuts in the tires Rpunctures Rtears in the tires Rbulges on tires Rdeformation or severe corrosion on wheels Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 265). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface. All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems. Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (Y page 267). Observe the notes on the emergency spare wheel (Y page 297). The service life of tires depends, among other things, on the following factors: RDriving style pressure RDistance covered RTire Notes on tire tread G WARNING Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. Minimum tire tread depth for: RSummer tires: â in (3 mm) tires: ã in (4 mm) For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached. RM+S Marking : shows where the bar indicator (arrow) for tread wear is integrated into the tire tread. Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once a tread depth of Z Wheels and tires other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged. 265 266 Winter operation approximately á in (1.6 mm) has been reached. If this is the case, the tire is so worn that it must be replaced. Selecting, mounting and replacing tires Wheels and tires ROnly mount tires and wheels of the same type and make. Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics" section (Y page 247). ROnly mount tires of the correct size onto the wheels. RBreak in new tires at moderate speeds for the first 60 miles (100 km). They only reach their full performance after this distance. RDo not drive with tires which have too little tread depth, as this significantly reduces the traction on wet roads (hydroplaning). RReplace the tires after six years at the latest, regardless of wear. Observe the notes on the emergency spare wheel (Y page 297). MOExtended tires (tires with run-flat properties) With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tires with a flat tire (Y page 247). Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit can be obtained from a qualified specialist workshop. Winter operation General notes You can find information about this in the Digital Operator's Manual. Driving with summer tires At temperatures below 45 ‡ (+7 †), summer tires lose elasticity and therefore traction and braking power. Change the tires on your vehicle to M+S tires. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage. G WARNING Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately. M+S tires G WARNING M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter and do not provide sufficient traction. There is a risk of an accident. M+S tires with a tread depth of less than ã in (4 mm) must be replaced immediately. Further information can be found in the Digital Operator's Manual. Tire pressure G WARNING If snow chains are installed to the front wheels, they may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires. There is a risk of an accident. To avoid hazardous situations: Rnever install snow chains to the front wheels Ralways install snow chains in pairs to the rear wheels. Further information can be found in the Digital Operator's Manual. Tire pressure Tire pressure specifications Important safety notes G WARNING i The specifications on the sample Tire and Loading Information placard and tire pressure tables are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications that are valid for your vehicle can be found on the Tire and Loading Information placard and tire pressure table on the vehicle. General notes The recommended tire pressures for the tires mounted at the factory can be found on the labels described here. Operation with an emergency spare wheel: information on operation with an emergency spare wheel can be found in the general notes in the "Emergency spare wheel" section (Y page 298). Further information on tire pressures can be obtained at a qualified specialist workshop. Tire and Loading Information placard Underinflated or overinflated tires pose the following risks: Rthe tires may burst, especially as the load and vehicle speed increase. Rthe tires may wear excessively and/or unevenly, which may greatly impair tire traction. Rthe driving characteristics, as well as steering and braking, may be greatly impaired. There is a risk of an accident. Follow recommended tire inflation pressures and check the pressure of all the tires including the spare wheel: Rmonthly, at least the load changes Rbefore beginning a long journey Runder different operating conditions, e.g. off-road driving If necessary, correct the tire pressure. Rif : Recommended tire pressures The Tire and Loading Information placard is on the B-pillar on the driver's side (Y page 275). The Tire and Loading Information placard contains the recommended tire pressures for cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed. Z Wheels and tires Snow chains 267 268 Tire pressure Tire pressure table The tire pressure table is on the inside of the fuel filler flap. Example: tire pressure table for all tires permitted for this vehicle by the factory Wheels and tires The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Example: tire pressure table with tire dimensions If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of occupants and amounts of luggage. The actual number of seats may differ. Some tire pressure tables show only the rim diameters instead of the full tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire sidewall (Y page 280). If the tire pressures have been set to the lower values for lighter loads and/or lower road speeds, the pressures should be reset to the higher values: Rif you want to drive with an increased load and/or Rif you want to drive at higher road speeds i The tire pressures for increased loads and/or higher road speeds, shown in the tire pressure table, may have a negative effect on driving comfort. If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure. For more information, contact a qualified specialist workshop. Important notes on tire pressure G WARNING If the tire pressure drops repeatedly, the wheel, valve or tire may be damaged. Tire pressure that is too low may result in a tire blow-out. There is a risk of an accident. RCheck the tire for foreign objects. RCheck whether the wheel is losing air or the valve is leaking. Tire pressure G WARNING If you fit unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. Due to their design, retrofitted tire pressure monitors keep the tire valve open. This can also result in tire pressure loss. There is a risk of an accident. Only screw the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle onto the tire valve. Use a suitable pressure gauge to check the tire pressure. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitor, the tire pressure can be checked in the on-board computer. The tire temperature and pressure increase when the vehicle is in motion. This is dependent on the driving speed and the load. Therefore, you should only correct tire pressures when the tires are cold. The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven further than 1 mile (1.6 km) The tire temperature changes depending on the outside temperature, the vehicle speed and the tire load. If the tire temperature changes by 18 ‡ (10 †), the tire pressure changes by approximately 10 kPa (0.1 bar/ 1.5 psi). Take this into account when checking the pressure of warm tires. Only correct the tire pressure if it is too low for the current operating conditions. If you check the tire pressure when the tires are warm, the resulting value will be higher than if the tires were cold. This is normal. Do not reduce the tire pressure to the value specified for cold tires. The tire pressure would otherwise be too low. Observe the recommended tire pressures for cold tires: Ron the Tire and Loading Information placard on the B-pillar on the driver's side Rin the tire pressure table on the inside of the fuel filler flap Underinflated or overinflated tires Underinflated tires G WARNING Tires with pressure that is too low can overheat and burst as a consequence. In addition, they also suffer from excessive and/or irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too low in all the tires, including the spare wheel. Underinflated tires may: Roverheat, leading to tire defects affect handling Rwear excessively and/or unevenly Rhave an adverse effect on fuel consumption Radversely Overinflated tires G WARNING Tires with excessively high pressure can burst because they are damaged more easily by road debris, potholes etc. In addition, they also suffer from irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too high in all the tires, including the spare wheel. Overinflated tires may: Rincrease the braking distance Radversely affect handling Z Wheels and tires If you are unable to rectify the damage, contact a qualified specialist workshop. 269 270 Tire pressure excessively and/or unevenly an adverse effect on ride comfort Rbe more susceptible to damage Checking tire pressures manually Maximum tire pressures Remove the valve cap of the tire that is to be checked.

This enables the system to detect significant pressure loss in a tire. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display. You can recognize the tire pressure loss warning by the Run Flat Indicator Active Press 'OK' to Restart message which appears in the Serv. menu of the multifunction display. Information on the message display can be found in the "Restarting the tire pressure loss warning system" section (Y page 271). Tire pressure The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 267). The tire pressure loss warning does not replace the need to regularly check the tire pressure. An even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system. The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. The function of the tire pressure loss warning system is limited or delayed if: Rsnow chains are mounted on your vehicle's tires. Rroad conditions are wintry. Ryou are driving on sand or gravel. Ryou adopt a very sporty driving style (cornering at high speeds or driving with high rates of acceleration). Ryou are driving with a heavy load (in the vehicle or on the roof). Restarting the tire pressure loss warning system Restart the tire pressure loss warning system if you have: Rchanged the tire pressure Rchanged the wheels or tires Rmounted new wheels or tires X Before restarting, make sure that the tire pressures are set properly on all four tires for the respective operating conditions. The recommended tire pressure can be found on the Tire and Loading Information placard on the B-pillar on the driver's side. Additionally, a tire pressure table is attached to the fuel filler flap. The tire pressure loss warning system can only give reli- able warnings if you have set the correct tire pressure. If an incorrect tire pressure is set, these incorrect values will be monitored.

X Z Wheels and tires Important safety notes 271 272 Tire pressure Tire pressure monitor General notes Wheels and tires If a tire pressure monitor is installed, the vehicle's wheels have sensors that monitor the tire pressures in all four tires. The tire pressure monitor warns you if the pressure drops in one or more of the tires. The tire pressure monitor only functions if the corresponding sensors are installed in all wheels. Information on tire pressures is displayed in the multifunction display. After a few minutes of driving, the current tire pressure of each tire is shown in the Service menu of the multifunction display, see illustration (example). For information on the message display, refer to the "Checking the tire pressure electronically" section (Y page 273). Important safety notes G WARNING Each tire, including the spare (if provided), should be checked at least once every two weeks when cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver's door B-pillar or the tire pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or, if available, the tire pressure label, you should determine the proper tire pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale lights up, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the warning lamp will flash for approximately a minute and then remain continuously illuminated. This sequence will be repeated every time the vehicle is started as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate Tires and wheels allow the TPMS to continue to function properly. It is the driver's responsibility to set the tire pressure to that recommended for cold tires which is suitable for the operating situation (Y page 267). Note that the correct tire pressure for the current operating situation must first be taught-in to the tire pressure monitor. If there is a substantial loss of pressure, the warning threshold for the warning message is Tire pressure Rif the warning lamp is lit continuously, the tire pressure on one or more tires is significantly too low. The tire pressure monitor is not malfunctioning. Rif the warning lamp flashes for around a minute and then remains lit constantly, the tire pressure monitor is malfunctioning. In addition to the warning lamp, a message appears in the multifunction display. Observe the information on display messages (Y page 183). It may take up to ten minutes for a malfunction of the tire pressure monitor to be indicated. A malfunction will be indicated by the tire pressure warning lamp flashing for approximately one minute and then remaining lit. When the malfunction has been rectified, the tire pressure warning lamp goes out after a few minutes of driving. The tire pressure values indicated by the onboard computer may differ from those measured at a gas station with a pressure gage. The tire pressures shown by the on-board computer refer to those measured at sea level. At high altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by the on-board computer. In this case, do not reduce the tire pressures. The operation of the tire pressure monitor can be affected by interference from radio transmitting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle. Checking the tire pressure electronically Make sure that the SmartKey is in position 2 in the ignition lock (Y page 127). X Press the = or ; button on the steering wheel to select the Service menu. X Press the 9 or : button to select Tire Pressure. X Press the a button. The current tire pressure of each tire is shown in the multifunction display. X If the vehicle has been parked for over 20 minutes, the Tire pressure will be displayed after driving a few minutes message appears. After a teach-in process, the tire pressure monitor automatically detects new wheels or new sensors. As long as a clear allocation of the tire pressure value to the individual wheels is not possible, the Tire Pressure Monitor Active display message is shown instead of the tire pressure display. The tire pressures are already being monitored. If an emergency spare wheel is mounted, the system may continue to show the tire pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the spare wheel is mounted is not the same as the current tire pressure of the emergency spare wheel. Z Wheels and tires aligned to the reference values taught-in. Restart the tire pressure monitor after adjusting the pressure of the cold tires (Y page 274). The current pressures are saved as new reference values. As a result, a warning message will appear if the tire pressure drops significantly. The tire pressure monitor does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 267). The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. The tire pressure monitor has a yellow warning lamp in the instrument cluster for indicating pressure loss or a malfunction. Whether the warning lamp flashes or lights up indicates whether a tire pressure is too low or the tire pressure monitor is malfunctioning: 273 274 Tire pressure Tire pressure monitor warning messages If the tire pressure monitor detects a pressure loss in one or more tires, a warning message is shown in the multifunction display and the yellow tire pressure monitor warning lamp comes on. the Correct Tire Pressure message appears in the multifunction display, the tire pressure in at least one tire is too low and must be corrected at the next opportunity. RIf the Check Tires message appears in the multifunction display, the tire pressure in one or more tires has dropped significantly and the tires must be checked. RIf the Warning Tire Malfunction message appears in the multifunction display, the tire pressure in one or more tires has dropped suddenly and the tires must be checked. Observe the instructions and safety notes in the display messages in the "Tires" section (Y page 183). If the wheel positions on the vehicle are rotated, the tire pressures may be displayed for the wrong positions for a short time. This is rectified after a few minutes of driving, and the tire pressures are displayed for the correct positions.

Radio type approval for the tire pressure monitor In certain countries, a radio type approval for the tire pressure monitor may be required. Loading the vehicle 275 The radio type approval number for the tire pressure monitor can be found in the "Wheels and tires" section of the Digital Operator's Manual. Loading the vehicle Instruction labels for tires and loads G WARNING Overloaded tires can overheat, causing a blowout. Overloaded tires can also impair the steering and driving characteristics and lead to brake failure. There is a risk of accident. Observe the load rating of the tires. The load rating must be at least half of the GAWR of your vehicle. Never overload the tires by exceeding the maximum load. : B-pillar, driver's side Maximum permissible gross vehicle weight rating (1) The Tire and Loading Information placard is on the B-pillar on the driver's side. The Tire and Loading Information placard shows the maximum permissible number of occupants and the maximum permissible vehicle load. It also contains details of the tire sizes and corresponding pressures for tires mounted at the factory. (2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle identification plate informs you of the gross vehicle weight rating. It is made up of the vehicle weight, all vehicle occupants, the fuel and the cargo. You can also find information about the maximum gross axle weight rating on the front and rear axle. The maximum gross axle weight rating is the maximum weight that can be carried by one axle (front or rear axle). Never exceed the maximum load or the maximum gross axle weight rating for the front or rear axle. X Specification for maximum gross vehicle weight : is listed in the Tire and Loading Information placard: "The combined weight of occupants and cargo should never exceed XXX kilograms or XXX lbs." The gross weight of all vehicle occupants, load and luggage must not exceed the specified value. i The specifications shown on the Tire and Loading Information placard in the illustration are examples. The maximum permissible gross vehicle weight rating is vehiclespecific and may differ from that in the illustration. You can find the valid maximum permissible gross vehicle weight rating for your vehicle on the Tire and Loading Information placard. Z Wheels and tires Two instruction labels on your vehicle show the maximum possible load. 276 Loading the vehicle Number of seats Wheels and tires Maximum number of seats : indicates the maximum number of occupants allowed to travel in the vehicle. This information can be found on the Tire and Loading Information placard. i The specifications shown on the Tire and Loading Information placard in the illustration are examples. The number of seats is vehicle-specific and can differ from the details shown. The number of seats in your vehicle can be found on the Tire and Loading Information placard. Determining the correct load limit Step-by-step instructions The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle Safety Act of 1966". X Step 1: Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s Tire and Loading Information placard. X Step 2: Determine the combined weight of the driver and passengers that will be riding in your vehicle. X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or XXX lbs. Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150-lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 - 750 (5 x 150) = 650 lbs). X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. X Loading the vehicle 277 Example: steps 1 to 3 The following table shows examples on how to calculate total and cargo load capacities with varying seating configurations and number and size of occupants. The following examples use a load limit of 1500 lbs (680 kg). This is for illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on your vehicle's Tire and Loading Information placard (Y page 275). The greater the combined weight of the occupants, the lower the maximum luggage load.

Details can be found on the vehicle identification plate on the B-pillar on the driver's side of the vehicle (Y page 275). Permissible Gross Vehicle Weight Rating (GVWR): the gross weight of the vehicle, all passengers, load and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight. Gross Axle Weight Rating (GAWR): the maximum permissible weight that can be carried by one axle (front or rear axle). To ensure that your vehicle does not exceed the maximum permissible values (gross vehicle weight and maximum gross axle weight rating), have your loaded vehicle (including driver, occupants, cargo, and full trailer load if applicable) weighed on a suitable vehicle weighbridge. Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers have to grade tires using three performance factors: : tread wear grade, ; traction grade and = temperature grade. These regulations do not apply to Canada. Nevertheless, all tires sold in North America are provided with the corresponding quality grading markings on the sidewall of the tire. Quality grades can be found, where applicable, on the tire sidewall between tread shoulder and maximum section width. All about wheels and tires RTread wear grade: 200 grade: AA RTemperature grade: A All passenger car tires must conform to the statutory safety requirements in addition to these grades. RTraction i The actual values for tires are vehiclespecific and may deviate from the values in the illustration. Treadwear The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. government course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction G WARNING The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. ! Avoid wheelspin. This can lead to damage to the drive train. The traction grades – from highest to lowest – are AA, A, B and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces. You should pay special attention to road conditions when temperatures are around freezing point. Mercedes-Benz recommends a minimum tread depth of ã in (4 mm) on all four winter tires. Observe the legally required minimum tire tread depth (Y page 265). Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires. The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving. Further information on winter tires (M+S tires) can be found in the Digital Operator's Manual. Temperature G WARNING The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure. The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

RIf a service specification is available, the maximum speed is limited according to the speed rating in the service specification. Example: 245/40 ZR18 97 Y. In this example, "97 Y" is the service specification. The letter "Y" represents the speed rating. The maximum speed of the tire is limited to 186 mph (300 km/h). If the size description of your tire includes "ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. RThe size description for all tires with maximum speeds of over 186 mph (300 km/h) must include "ZR", and the service specification must be given in parentheses. Example: 275/40 ZR 18 (99 Y). Speed rating "(Y)" indicates that the maximum speed of the tire is over 186 mph (300 km/h). Ask the tire manufacturer about the maximum speed.

DOT, Tire Identification Number (TIN) US tire regulations stipulate that every tire manufacturer or retreader must imprint a TIN in or on the sidewall of each tire produced. 283 Tire type code: tire type code ? can be used by the manufacturer as a code to describe specific characteristics of the tire. Date of manufacture: date of manufacture A provides information about the age of a tire. The first and second positions represent the week of manufacture, starting with "01" for the first calendar week. Positions three and four represent the year of manufacture. For example, a tire that is marked "2614" was manufactured in week 26 in 2014. i Tire data is vehicle-specific and may deviate from the data in the example. The TIN is a unique identification number. The TIN enables the tire manufacturers or retreaders to inform purchasers of recalls and other safety-relevant matters. It makes it possible for the purchaser to easily identify the affected tires. The TIN is made up of manufacturer identification code ;, tire size =, tire type code ? and manufacturing date A. DOT (Department of Transportation): tire symbol : marks that the tire complies with the requirements of the U.S. Department of Transportation. Manufacturer identification code: manufacturer identification code ; provides details on the tire manufacturer. New tires have a code with two symbols. Retreaded tires have a code with four symbols. For further information about retreaded tires, see (Y page 264). Tire size: identifier = describes the tire size.

Wheels and tires Uniform Tire Quality Grading Standards A uniform standard to grade the quality of tires with regards to tread quality, tire traction and temperature characteristics. The quality grading assessment is made by the manufacturer following specifications from the U.S. government. The ratings are molded into the sidewall of the tire. Recommended tire pressures The recommended tire pressure applies to the tires mounted at the factory. The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed. The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Increased vehicle weight due to optional equipment The combined weight of all standard and optional equipment available for the vehicle, regardless of whether it is actually installed on the vehicle or not. Rim This is the part of the wheel on which the tire is mounted. GAWR (Gross Axle Weight Rating) The GAWR is the maximum gross axle weight rating. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the vehicle identification plate on the B-pillar on the driver's side. Speed rating The speed rating is part of the tire identification. It specifies the speed range for which the tire is approved. GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of the vehicle including fuel, tools, the spare wheel, accessories installed, occupants, luggage and the drawbar noseweight, if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the vehicle identification plate on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross weight of a fully loaded vehicle (the weight of the vehicle including all accessories, occupants, fuel, luggage and the drawbar noseweight, if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side. Maximum loaded vehicle weight The maximum weight is the sum of: Rthe curb weight of the vehicle weight of the accessories Rthe load limit Rthe weight of the factory installed optional equipment Rthe Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corresponds to 1 psi. Another unit for tire pressure is bar. 100 kilopascals (kPa) are the equivalent of 1 bar. Load index In addition to the load-bearing index, the load index may also be imprinted on the sidewall of the tire. This specifies the load-bearing capacity more precisely. All about wheels and tires Maximum load rating The maximum load rating is the maximum permissible weight in kilograms or lbs for which a tire is approved. Maximum permissible tire pressure Maximum permissible tire pressure for one tire. Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two. PSI (pounds per square inch) A standard unit of measure for tire pressure. Aspect ratio Relationship between tire height and tire width in percent. Tire pressure Pressure inside the tire applying an outward force to every square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. Cold tire pressure The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven further than 1 mile (1.6 km) Tread The part of the tire that comes into contact with the road. Bead The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim. Sidewall The part of the tire between the tread and the bead. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard parts and more than 2.3 kg (5 lbs). These optional extras, such as high-performance brakes, level control, a roof rack or a highperformance battery, are not included in the curb weight and the weight of the accessories. TIN (Tire Identification Number) This is a unique identifier which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date. Load bearing index The load bearing index (also load index) is a code that contains the maximum load bearing capacity of a tire. Traction Traction is the result of friction between the tires and the road surface. Tread wear indicators Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of á in (1.6 mm) has been reached. Z Wheels and tires Curb weight The weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the air-conditioning system and optional equipment if these are installed in the vehicle, but does not include passengers or luggage. 285 286 Changing a wheel Occupant distribution The distribution of occupants in a vehicle at their designated seating positions. Total load limit Nominal load and luggage load plus 68 kg (150 lbs) multiplied by the number of seats in the vehicle. Changing a wheel Wheels and tires Flat tire The "Breakdown assistance" section (Y page 247) contains information and notes on how to deal with a flat tire. Information on driving with MOExtended tires in the event of a flat tire can be found under "MOExtended tires (tires with run-flat characteristics" (Y page 247). Vehicle with emergency spare wheel: in the event of a flat tire, the emergency spare wheel is mounted as described under "Mounting a wheel" (Y page 287). Rotating the wheels G WARNING Interchanging the front and rear wheels may severely impair the driving characteristics if the wheels or tires have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of accident. Rotate front and rear wheels only if the wheels and tires are of the same dimensions. ! On vehicles equipped with a tire pressure monitor, electronic components are located in the wheel. Tire-mounting tools should not be used near the valve. This could damage the electronic components. Only have tires changed at a qualified specialist workshop. Always observe the instructions and safety notes in the "Mounting a wheel" section (Y page 287). The wear patterns on the front and rear tires differ, depending on the operating conditions. Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically wear more on the shoulders and the rear tires in the center. On vehicles that have the same size front and rear wheels, you can rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If no warranty book is available, the tires should be rotated every 3,000 to 6,000 miles (5,000 to 10,000 km). Depending on tire wear, this may be required earlier. Do not change the direction of wheel rotation. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rotated. Check the tire pressure and, if necessary, restart the tire pressure loss warning system (Y page 271) or the tire pressure monitor (Y page 274). Direction of rotation Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. These advantages can only be gained if the tires are installed corresponding to the direction of rotation. An arrow on the sidewall of the tire indicates its correct direction of rotation. Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tires from oil, grease, gasoline and diesel. Changing a wheel 287 Preparing the vehicle Stop the vehicle on solid, non-slippery and level ground. X Apply the parking brake.
