Diagnostic devices should therefore only be connected by a qualified specialist workshop. & WARNING Risk of accident due to con‐ necting devices to the diagnostics con‐ nection If you connect devices to the diagnostics connection of the vehicle, the function of vehicle systems and operating safety may be impaired. # For safety reasons, we recommend that you only use and connect products approved by your authorized MercedesBenz Center. & WARNING Risk of accident due to objects in the driver's footwell Objects in the driver's footwell may impede pedal travel or block a depressed pedal. This jeopardizes the operating and road safety of the vehicle. # Stow all objects in the vehicle securely so that they cannot get into the driver's footwell. # Always install the floor mats securely and as prescribed in order to ensure that there is always sufficient room for the pedals. # Do not use loose floor mats and do not place floor mats on top of one another. * NOTE Battery discharging from using devices connected to the diagnostics connection Using devices at the diagnostics connection drains the battery. # Check the charge level of the battery. 23 24 # General notes If the charge level is low, charge the battery, e.g. by driving a considerable distance. Please also note the information about the 12 V battery and short-distance trips in the "Driving and Parking" chapter (/ page 152). Connecting and using another device with the diagnostics connection can have the following effects: R Malfunctions in the vehicle system R Permanent damage to vehicle components Please refer to the warranty terms and condi‐ tions for this matter. Moreover, connecting equipment to the diagnos‐ tics connection can lead to emissions monitor‐ ing information being reset, for example. This may lead to the vehicle failing to meet the requirements of the next emissions inspection during the main inspection. Qualified specialist workshop An authorized Mercedes-Benz Center is a quali‐ fied specialist workshop. It has the necessary special skills, tools and qualifications to cor‐ rectly carry out the work required on your vehi‐ cle. This particularly applies to safety-relevant works.

Data storage Data processing in the vehicle Electronic control units Electronic control units are installed in your vehi‐ cle. Control units process data which, for exam‐ ple, they receive from vehicle sensors, generate themselves or exchange between themselves. Some control units are required for the safe operation of your vehicle, some assist you when driving, such as driver assistance systems, while others enable convenience or infotainment func‐ tions. The following provides you with general informa‐ tion regarding data processing in the vehicle. Additional information regarding exactly which data in your vehicle are collected, saved and transmitted to third parties, and for what pur‐ pose, can be found in the information directly related to the functional characteristics in ques‐ tion in their respective Operator's Manual. This information is also available online and, depend‐ ing on the vehicle equipment, digitally. Personal data Every vehicle is identified by a unique vehicle identification number. Depending on the coun‐ try, this vehicle identification number can be used by, for example, governmental authorities to determine the identity of the owner. There are other possibilities to use data collected from the vehicle to identify the owner or driver, such as the license plate number. Therefore, data generated or processed by con‐ trol units may be attributable to a person or, under certain conditions, become attributable to 27 a person. Depending on which vehicle data are available, it may be possible to make inferences about, for example, your driving behavior, your location, your route or your use patterns. Legal requirements regarding the disclosure of data If legally required to do so, manufacturers are, in individual cases, legally obliged to provide gov‐ ernmental entities, upon request and to the extent required, data stored by the manufac‐ turer. For example, this may be the case during the investigation of a criminal offense. Governmental entities are themselves, in individ‐ ual cases and within the applicable legal frame‐ work, authorized to read out data from the vehi‐ cle. In the case of an accident, information that can help with an investigation can, therefore, be taken from the airbag control unit, for example. Operational data in the vehicle This is data regarding the operation of the vehi‐ cle, which have been processed by control units. This includes the following data, for example: R Vehicle status information such as the speed, longitudinal acceleration, lateral accelera‐ 28 R General notes tion, number of wheel revolutions or the fas‐ tened seat belts display Ambient conditions, such as temperature, rain sensor or distance sensor Generally, the use of these data is temporary; they will not be stored beyond the period of operation and will only be processed within the vehicle itself. Control units often contain data memories for vehicle keys, for example. Their use permits the temporary or permanent docu‐ mentation of technical information about the vehicle's operating state, component loads, maintenance requirements and technical events or malfunctions. Depending on the vehicle equipment, the follow‐ ing data are stored: R Operating status of system components, such as fill levels, tire pressure or battery status R Malfunctions or faults in important system components, such as lights or brakes R System reactions in special driving situa‐ tions, such as airbag deployment or the inter‐ vention of stability control systems R Information on events leading to vehicle damage In certain cases, it may be required to store data that would have otherwise been used only tem‐ porarily. This may be the case if the vehicle has detected a malfunction, for example. If you use services, such as repair services and maintenance work, stored operational data as well as the vehicle identification number can be read out and used. They can be read out by service network employees, such as workshops and manufacturers or third parties, such as breakdown services. The same is true in the case of warranty claims and quality assurance measures. In general, the readout is performed via the legally prescribed port for the diagnostics con‐ nection in the vehicle. The operational data that are read out document technical states of the vehicle or of individual components and assist in the diagnosis of malfunctions, compliance with warranty obligations and quality improvement. To that end, these data, in particular information about component loads, technical events, mal‐ functions and other faults may be transmitted along with the vehicle identification number to the manufacturer. Furthermore, the manufac‐ turer is subject to product liability. For this rea‐ son the manufacturer also uses operational data from the vehicle, for example, for recalls. These data can also be used to examine the custom‐ er's warranty and guarantee claims. Fault memories in the vehicle can be reset by a service outlet or at your request as part of repair or maintenance work. Convenience and infotainment functions You can store convenience settings and individ‐ ual settings in the vehicle and change or reset them at any time. Depending on the vehicle equipment, this includes the following settings, for example: R Seat and steering wheel positions R Suspension and climate control settings R Individual settings, such as interior lighting Depending on the selected equipment, you can import data into vehicle infotainment functions yourself. General notes Depending on the vehicle equipment, this includes the following data, for example: R Multimedia data, such as music, films or pho‐ tos for playback in an integrated multimedia system R Address book data for use in connection with an integrated hands-free system or an inte‐ grated navigation system R Entered navigation destinations R Data about the use of Internet services These data for convenience and infotainment functions may be saved locally in the vehicle or they may be located on a device which you have connected to the vehicle, such as a smartphone, USB flash drive or MP3 player. If you have entered these data yourself, you can delete them at any time. This data is transmitted from the vehicle to third parties only at your request. This applies, in par‐ ticular, when you use online services in accord‐ ance with the settings that you have selected. Smartphone integration (e.g. Android Auto or Apple CarPlay®) If your vehicle is accordingly equipped, you can connect your smartphone or another mobile end device to the vehicle. You can then control them by means of the control elements integrated in the vehicle. Images and audio from the smart‐ phone can be output via the multimedia system. Certain information is simultaneously transfer‐ red to your smartphone. Depending on the type and integration, this includes position data, day/ night mode and other general vehicle statuses. For more information please consult the Opera‐ tor's Manual of the vehicle/infotainment system. This integration allows the use of selected smartphone apps, such as navigation or music player apps. There is no further interaction between the smartphone and the vehicle; in par‐ ticular, vehicle data is not directly accessible. The type of additional data processing is deter‐ mined by the provider of the app being used. Which settings you can make, if any, depends on the specific app and the operating system of your smartphone. 29 Online services Wireless network connection If your vehicle has a wireless network connec‐ tion, it enables data to be exchanged between your vehicle and additional systems. The wire‐ less network connection is made possible by the vehicle's own transmitter and receiver or by a mobile end device that you have brought into the vehicle, for example, a smartphone. Online func‐ tions can be used via the wireless network con‐ nection. This includes online services and appli‐ cations/apps provided to you by the manufac‐ turer or by other providers. Manufacturer's services Regarding the manufacturer's online services, the individual functions are described by the manufacturer in a suitable place, for example, in the Operator's Manual or on the manufacturer's website, where the relevant data protection information is also given. Personal data may be used for the provision of online services. Data are exchanged via a secure connection, such as the manufacturer's designated IT systems. Any personal data which are collected, processed 30 General notes and used, other than for the provision of serv‐ ices, is done so exclusively on the basis of legal permission. This is the case, for example, for a legally prescribed emergency call system, a con‐ tractual agreement or when consent has been given. You can have services and functions, some of which are subject to a fee, activated or deactiva‐ ted. This excludes legally prescribed functions and services, such as an emergency call system. Third party services If you use online services from other providers (third parties), these services are the responsi‐ bility of the provider in question and subject to that provider's data protection conditions and terms of use. As a general rule, the manufac‐ turer has no influence on the content exchanged. For this reason, when services are provided by third parties, please ask the service provider in question for information about the type, extent and purpose of the collection and use of per‐ sonal data. Data protection rights Depending on your country or the equipment and range of functions of your vehicle as well as the services you use and the services on offer, you are entitled to different data protection rights. Further information on data protection and your data protection rights can either be found on the manufacturer's website or you will receive this information as part of the various services and service offers. There you will also find the contact information for the manufac‐ turer and its data protection officers. At a workshop, for example, with the support of a specialist and possibly for a fee, you can have data read out which is stored only locally in the vehicle. MBUX multimedia system/Mercedes me connect If the vehicle is equipped with the MBUX multi‐ media system or Mercedes me connect, addi‐ tional data about the vehicle's operation, the use of the vehicle in certain situations, and the loca‐ tion of the vehicle may be compiled by the MBUX multimedia system or Mercedes me con‐ nect. For additional information, please refer to the "MBUX multimedia system" section and/or the Mercedes me connect Terms and Conditions. Event data recorders USA only: This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like sit‐ uations, such as an airbag deployment or hitting a road obstacle, data that will assist in under‐ standing how a vehicle's systems performed. 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: R How various systems in your vehicle were operating R Whether or not the driver and front passenger seat belts were buckled/fastened General notes R R How far (if at all) the driver was depressing the accelerator and/or brake pedal and How fast the vehicle was traveling This data can help provide a better understand‐ ing of the circumstances in which accidents 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 accident location) is recorded. However, other parties, such as law enforcement, could combine EDR data with the type of personally identifying data routinely acquired during a crash investigation. To read data recorded by an EDR, special equip‐ ment 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 mat‐ ters as a tool in accident reconstruction, acci‐ dent 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 ("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 with‐ out the consent of the vehicle owner or, if the vehicle is leased, without the consent of the les‐ see. 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, alter‐ ing, modifying or removing the EDR component may result in a malfunction of the Restraint Sys‐ tem 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 December 31 2016, 17 states have enacted laws relating to EDRs.

In the event of an accident, the restraint system can also reduce the forces to which the vehicle occupants are subjected. A seat belt can only provide the best level of pro‐ tection if it is worn correctly. Depending on the detected accident situation, Emergency Tension‐ ing Devices and/or airbags supplement the pro‐ tection offered by a correctly worn seat belt. Emergency Tensioning Devices and/or airbags are not deployed in every accident. In order for the restraint system to provide the intended level of protection, each vehicle occu‐ pant must observe the following information: R Fasten seat belts correctly. R Sit in an almost upright seat position with their back against the seat backrest. R Sit with their feet resting on the floor, if pos‐ sible. R Always secure persons under 5 ft (1.50 m) tall in an additional restraint system suitable for Mercedes-Benz vehicles. However, no system available today can com‐ pletely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and airbag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the airbag deploying. 33 Reduced restraint system protection & WARNING Risk of injury or death due to modifications to the restraint system Vehicle occupants may no longer be protec‐ ted as intended if alterations are made to the restraint system. # Never alter the parts of the restraint system. # Never tamper with the wiring or any electronic component parts or their software. If it is necessary to modify the vehicle to accom‐ modate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for details, contact our Customer Assistance Center on 1-800-FOR-MERCedes (1‑800‑367‑6372). Restraint system functionality When the vehicle is switched on, a self-test is performed, during which the 6 restraint sys‐ 34 Occupant safety tem warning lamp lights up. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are then functional. Malfunctioning restraint system A malfunction has occurred in the restraint sys‐ tem if: R The 6 restraint system warning lamp does not light up when the vehicle is switched on R The 6 restraint system warning lamp lights up continuously or repeatedly during a journey & WARNING Risk of injury due to malfunc‐ tions in the restraint system Components in the restraint system may be activated unintentionally or not deploy as planned in an accident. # Have the restraint system checked and repaired immediately at a qualified spe‐ cialist workshop. Function of the restraint system in an acci‐ dent How the restraint system works depends on the severity of the impact detected and the apparent type of accident: R Frontal impact R Rear impact R Side impact R Rollover The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is preemptive in nature. The triggering/deployment of the components of the restraint system must take place in good time at the start of the colli‐ sion. Factors which can only be seen and measured after a collision has occurred cannot play a deci‐ sive role in airbag deployment. Nor do they pro‐ vide an indication of airbag deployment. The vehicle may be deformed significantly with‐ out an airbag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of vehicle deceleration is not high. Conversely, an airbag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, this may result in sufficiently high levels of vehicle decel‐ eration. Depending on the detected deployment situa‐ tion, the components of the restraint system can be activated or deployed independently of each other: R Emergency Tensioning Device: frontal impact, rear impact, side impact, rollover R Driver's airbag, front passenger airbag: fron‐ tal impact R Knee airbag: frontal impact R Side airbag: side impact R Window curtain airbag: side impact, rollover, frontal impact R PRE-SAFE® Impulse Side: side impact The front passenger airbag can only be deployed in an accident if the PASSENGER AIR BAG OFF Occupant safety indicator lamp is off. If the front passenger seat is occupied, make sure, both before and during the journey, that the status of the front passenger airbag is correct (/ page 44). & WARNING Risk of burns from hot air bag components The air bag parts are hot after an air bag has been deployed. # Do not touch the air bag parts. # Have a deployed air bag replaced at a qualified specialist workshop as soon as possible. Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, partic‐ ularly if an Emergency Tensioning Device is trig‐ gered or an airbag deployed. If the Emergency Tensioning Devices are trig‐ gered or an airbag is deployed, you will hear a bang, and a small amount of powder may also be released: R The bang will not generally affect your hear‐ ing. R In general, the powder released is not haz‐ ardous to health but may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions. Provided it is safe to do so, leave the vehicle immediately or open the window in order to prevent breathing difficulties. Airbags and pyrotechnic Emergency Tensioning Devices contain perchlorate material, which may require special handling or environmental pro‐ tection measures. National guidelines regarding waste disposal must be observed. In California, see https://dtsc.ca.gov/. Using the search function, you will find information on perchlo‐ rate, for example. 35 Seat belts Protection provided by the seat belt Always fasten your seat belt correctly before starting a journey. A seat belt can only provide the best level of protection if it is worn correctly. & WARNING Risk of injury or death due to incorrectly fastened seat belt If the seat belt is not worn correctly, it can‐ not perform its intended protective function. In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly. # Always ensure that all vehicle occu‐ pants have their seat belts fastened correctly and are sitting properly. Always observe the instructions about the cor‐ rect driver's seat position and adjusting the seat (/ page 89). 36 Occupant safety In order for the correctly worn seat belt to pro‐ vide the intended level of protection, each vehi‐ cle occupant must observe the following infor‐ mation: R The seat belt must not be twisted and must fit tightly and snugly across the body. R The seat belt must be routed across the cen‐ ter of the shoulder and as low down across the hips as possible. R The shoulder section of the seat belt should not touch your neck nor be routed under your arm or behind your back. R Avoid wearing bulky clothing, e.g. a winter coat. R Push the lap belt down as far as possible across your hips and pull tight with the shoul‐ der section of the belt. Never route the lap belt across your abdomen. Pregnant women must also take particular care with this. R Never route the seat belt across sharp, poin‐ ted, abrasive or fragile objects. R R Only one person should use each seat belt at any one time. Never allow babies and chil‐ dren to travel sitting on the lap of another vehicle occupant. Never secure objects with a seat belt if the seat belt is also being used by one of the vehicle's occupants. Always observe the instructions for loading the vehicle when securing objects, luggage or loads (/ page 105). Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat. The seat belts on the following seats are equip‐ ped with a special seat belt retractor: R Front passenger seat R Rear seats Activate or deactivate the special seatbelt retractor (/ page 52). If children are traveling in the vehicle, be sure to observe the instructions and safety notes on "Children in the vehicle" (/ page 49). Limitations of the protection provided by the seat belt & WARNING Risk of injury or death due to an incorrect seat position The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position. In particular, you could slip beneath the seat‐ belt and become injured. # Adjust the seat properly before begin‐ ning your journey. # Always ensure that the seat backrest is in an almost vertical position and that the shoulder belt is routed across the center of your shoulder. & WARNING Risk of injury or death when additional restraint systems are not used for persons with a smaller stature Persons under 5 ft (1.50 m ) tall cannot wear the seat belt correctly without a suitable additional restraint system. Occupant safety # Always secure persons under 5 ft (1.50 m) tall in a suitable restraint sys‐ tem. & WARNING Danger of injury or death due to blocked seat belt anchorage The restraint effect of the seat belt is impaired if objects between the front seat and the door are blocking the movable seat belt anchorage on the front seat. # Before starting a journey, make sure that there are no objects between the front seat and the door. & WARNING Risk of injury or death due to damaged or modified seat belts Seat belts cannot provide protection in the following situations: R The seat belt is damaged, has been modi‐ fied, is extremely dirty, bleached or dyed R R The seat belt buckle is damaged or extremely dirty Modifications have been made to the Emergency Tensioning Device, seat belt anchorage or seat belt retractor Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modified or damaged seat belts could tear or fail in the event of an accident, for example. Modified Emergency Tensioning Devices could accidentally trigger or fail to function as intended. # Never modify the seat belt system, for example the seat belt, seat belt buckle, Emergency Tensioning Device, seat belt anchorage and seat belt retractor. # Make sure that the seat belts are undamaged, not worn and clean. # Always have the seat belts checked immediately after an accident at a qualified specialist workshop. 37 Only use seat belts which have been approved for your vehicle by Mercedes-Benz. & WARNING Risk of injury or death from deployed pyrotechnic Emergency Ten‐ sioning Devices Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer opera‐ tional and are unable to perform their inten‐ ded protective function. # Therefore, have deployed pyrotechnic Emergency Tensioning Devices immedi‐ ately replaced at a qualified specialist workshop. Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. * NOTE Damage caused by trapping the seat belt If an unused seat belt is not fully retracted, it may become trapped in the door or in the seat mechanism. 38 # Occupant safety Always ensure that an unused seat belt is fully retracted. Fastening and adjusting seat belts If the seat belt is pulled quickly or sharply, the seat belt retractor locks. The seat belt strap can‐ not be pulled out any further. Always engage seat belt tongue 2 of the seat belt into seat belt buckle 1 of the cor‐ responding seat. # Press and hold the seat belt outlet release and slide seat belt outlet 3 into the desired position. # Let go of the seat belt outlet release and ensure that seat belt outlet 3 locks into position. % A seat belt can only provide the best level of protection if it is worn correctly. Observe the notes on fastening the seat belt (/ page 35). # * NOTE Deployment of components of the restraint system when the front passenger seat is unoccupied and a seat belt is buckled When the front passenger seat is unoccupied and the seat belt tongue of the seat belt is engaged in the seat belt buckle, components of the restraint system may deploy unneces‐ sarily on the front passenger side, e.g. the Emergency Tensioning Device. # Only buckle the seat belts as intended. % Observe the notes on correctly fastening the seat belt (/ page 35) and stowage options (/ page 105). Information on installing a child restraint sys‐ tem and on children traveling in the vehicle can be found in the "Children in the vehicle" section (/ page 52). Seat belt adjustment function Vehicles with PRE-SAFE®: After a front seat belt has been fastened, the automatic seat belt adjustment may apply a certain tightening force.

The front passenger airbag may otherwise be disabled by mistake, for example, in the follow‐ ing situations: R The front passenger transfers their weight by supporting themselves on a vehicle armrest. R The front passenger sits in such a way that their weight is raised from the seat surface. & WARNING Risk of injury or death due to a disabled front passenger airbag The front passenger airbag is disabled when the PASSENGER AIR BAG OFF indicator lamp is lit. A person in the front passenger seat could then, for example, come into contact with the vehicle interior, especially if the person is sitting too close to the cockpit. If the front passenger seat is occupied, always ensure that: R The classification of the person in the front passenger seat is correct and the front passenger airbag is enabled or disa‐ bled in accordance with the person in the front passenger seat. R The front passenger seat has been moved as far back as possible. R The person is seated correctly. # 43 Both before and during the journey, ensure that the status of the front passenger airbag is correct. If the front passenger seat is occupied, the clas‐ sification of the person or child restraint system on the front passenger seat takes place after the front passenger airbag shutoff self-test. The PASSENGER AIR BAG indicator lamps display the status of the front passenger airbag. Always observe the notes on the function of the PASSENGER AIR BAG indicator lamps (/ page 44). 44 Occupant safety Function of the PASSENGER AIR BAG indica‐ tor lamps Self-test of automatic front passenger airbag shutoff When the vehicle is switched on, a self-test is performed during which the two PASSENGER AIR BAG ON and OFF indicator lamps light up simultaneously. The status of the front passenger airbag is dis‐ played via the PASSENGER AIR BAG indicator lamps after the self-test: R ON is lit: the front passenger airbag may deploy during an accident. The indicator lamp goes out after 60 sec‐ onds. R ON and OFF are not lit: the front passenger airbag may deploy during an accident. R OFF is lit: the front passenger airbag is disa‐ bled. It will then not be deployed in the event of an accident. If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front passenger airbag. The PASSENGER AIR BAG OFF indicator lamp may be lit continuously or be off. If the PASSENGER AIR BAG OFF indicator lamp and the 6 restraint system warning lamp light up simultaneously, the front passenger seat may not be used. Also in this case, do not install a child restraint system on the front passenger seat. Have the automatic front passenger airbag shutoff checked and repaired immediately at a qualified specialist workshop. Status display If the front passenger seat is occupied, ensure, both before and during the journey, that the sta‐ tus of the front passenger airbag is correct for the current situation. After installing a rearward-facing child restraint system on the front passenger seat: PASSENGER AIR BAG OFF must be lit con‐ tinuously. & WARNING Risk of injury or fatal injury when using a rearward-facing child restraint system while the co-driver air‐ bag is enabled If you secure a child in a rearward-facing child restraint system on the co-driver seat and the PASSENGER AIR BAG OFF indicator lamp is off, the co-driver airbag can deploy in the event of an accident. The child could be struck by the airbag. Occupant safety # # Always ensure that the co-driver airbag is disabled. The PASSENGER AIR BAG OFF indicator lamp must be lit. NEVER use a rearward-facing child restraint system on a seat with an ENA‐ BLED FRONT AIRBAG; DEATH or SERI‐ OUS INJURY to the CHILD can occur. When installing a child restraint system on the front passenger seat, observe the vehicle-spe‐ cific information (/ page 58). Depending on the child restraint system and the stature of the child, the PASSENGER AIR BAG OFF indicator lamp may be off. In this case, do not install the rearward-facing child restraint system on the front passenger seat. Instead, install the rearward-facing child restraint system on a suitable rear seat. After installing a forward-facing child restraint system on the front passenger seat: depending on the child restraint system and the stature of the child, PASSENGER AIR BAG OFF may be lit continuously or be off. Always observe the following information. & WARNING Risk of injury or death due to incorrect positioning of the forwardfacing child restraint system If you secure a child in a forward-facing child restraint system on the front passenger seat that is positioned too close to the cockpit, in the event of an accident, the child could: R come into contact with the vehicle inte‐ rior if the PASSENGER AIR BAG OFF indi‐ cator lamp is lit, for example R be struck by the airbag if the PASSENGER AIR BAG OFF indicator lamp is off. # Always move the front passenger seat as far back as possible and fully retract the seat cushion length adjustment. While doing so, always make sure that the shoulder belt strap is correctly routed from the seat belt outlet of the vehicle to the shoulder belt guide on the child restraint system.

Always comply with the child restraint system manufacturer's installation instructions. When installing a child restraint system on the front passenger seat, observe the vehicle-spe‐ cific information (/ page 58). If a person is sitting on the front passenger seat: PASSENGER AIR BAG OFF may be lit con‐ tinuously or be off, depending on the person's stature. A person on the front passenger seat must always observe the following information: R If the front passenger seat is occupied by an adult or a person with a stature correspond‐ ing to that of an adult, the PASSENGER AIR BAG OFF indicator lamp must be off. This indicates that the front passenger airbag is enabled. If the PASSENGER AIR BAG OFF indicator lamp is lit continuously, an adult or person 46 R Occupant safety with a build corresponding to that of an adult must not use the front passenger seat. Instead, they should use a rear seat. If the 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 is either lit continuously or remains off, depending on the classification. If the PASSENGER AIR BAG OFF indicator lamp is off: move the front passenger seat as far back as possible, or the per‐ son of smaller stature should use a rear seat. If the PASSENGER AIR BAG OFF indicator lamp is lit continuously: the person of smaller stature should not use the front passenger seat. & WARNING Risk of injury or death when the PASSENGER AIR BAG OFF indicator lamp is lit If the PASSENGER AIR BAG OFF indicator lamp remains lit after the self-test, the front passenger airbag is disabled. If the front passenger seat is occupied, always ensure that: R The classification of the person in the front passenger seat is correct and the front passenger airbag is enabled or disa‐ bled in accordance with the person in the front passenger seat. R The person is seated properly with a cor‐ rectly fastened seat belt. R The front passenger seat has been moved as far back as possible. Be sure to also observe the following further related subjects: R Child restraint system on the front passenger seat (/ page 58) PRE-SAFE® system Function of PRE-SAFE® (anticipatory occu‐ pant protection) PRE-SAFE® is able to detect certain critical driv‐ ing situations and implement pre-emptive meas‐ ures to protect the vehicle occupants. PRE-SAFE® can implement the following meas‐ ures independently of each other: R Tightening the seat belts on the driver's seat and front passenger seat. R Closing the side windows. R Vehicles with sliding sunroof: close the sliding sunroof. R Vehicles with memory function: move the front passenger seat to a more favorable seat position. R Vehicles with multicontour seat: increase the air pressure in the seat side bolsters of the seat backrest. R PRE-SAFE® Sound: provided that the multi‐ media system is switched on, generates a Occupant safety brief noise signal to stimulate the innate pro‐ tective mechanism of a person's hearing. * NOTE Damage caused by objects in the footwell or behind the seat The automatic adjustment of the seat posi‐ tion may result in damage to the seat and/or the object. # Stow objects in a suitable place. Reversing the PRE-SAFE® system measures If an accident did not occur, the pre-emptive measures that were taken are reversed. You will need to perform certain settings your‐ self. # If the seat belt pre-tensioning is not reduced, move the seat backrest back slightly. The locking mechanism releases. Function of PRE-SAFE® PLUS (anticipatory occupant protection plus) PRE-SAFE® PLUS can detect certain impacts, particularly an imminent rear impact, and take pre-emptive measures to protect the vehicle occupants. These measures cannot necessarily prevent an imminent impact. PRE-SAFE® PLUS can implement the following measures independently of each other: R Tightening the seat belts on the driver's seat and front passenger seat. R Increasing brake pressure when the vehicle is stationary. This brake application is can‐ celed automatically when the vehicle pulls away. If an accident did not occur, the pre-emptive measures that were taken are reversed. System limits The system will not initiate any action in the fol‐ lowing situations: R When backing up 47 The system will not initiate any braking applica‐ tion in the following situations: R Whilst driving or R When entering or exiting a parking space while using Active Parking Assist Function of PRE-SAFE® Impulse Side If an imminent side impact is detected, PRESAFE® Impulse Side can pre-emptively move the front seat vehicle occupant's upper body towards the center of the vehicle. It does this by rapidly inflating an air cushion in the outer seat side bolster of the seat backrest on the side on which the impact is anticipated. This increases the distance between the door and the vehicle occupant. If PRE-SAFE® Impulse Side has been deployed or is faulty, the PRE-SAFE Impulse Side Inoperative See Operator's Manual display message appears (/ page 368). 48 Occupant safety Automatic measures after an accident Depending on the type and severity of the acci‐ dent, and depending on the vehicle's equipment, the following measures can be implemented, for example: R Automatic braking (post-collision brake) R Activating the hazard warning lights R Triggering an automatic emergency call (/ page 277) R Switching off the engine To start the vehicle again, switch the vehicle off and on once more (/ page 148). Depending on the type and severity of the accident, you may no longer be able to start the vehicle. R Switching off the fuel supply R Unlocking the vehicle doors R Lowering the side windows R Displaying the emergency guide on the cen‐ tral display R Switching on the interior lighting Function of the post-collision brake Depending on the accident situation, the postcollision brake can minimize the severity of a fur‐ ther collision or even avoid it. If an accident is detected, the post-collision brake can implement automatic braking. When the vehicle has come to a standstill, the electric parking brake is automatically applied. The driver can cancel automatic braking by tak‐ ing the following actions: R Braking more strongly than automatic brak‐ ing R Fully depressing the accelerator pedal with force Safely transporting children in the vehicle Always observe when children are traveling in the vehicle % Also strictly observe the safety notes for the specific situation. In this way you can recog‐ nize potential risks and avoid dangers if chil‐ dren are traveling in the vehicle (/ page 49). Be diligent Bear in mind that negligence when securing a child in the child restraint system may have seri‐ ous consequences. Always be diligent in secur‐ ing a child carefully before every journey. To improve protection for children younger than 12 years old or under 5 ft (1.50 m) in height, Mercedes-Benz recommends you observe the following information: R Always secure the child in a child restraint system suitable for this Mercedes-Benz vehi‐ cle. R The child restraint system must be appropri‐ ate to the age, weight and size of the child. R The vehicle seat must be suitable for instal‐ ling a child restraint system. Accident statistics show that children secured on the rear seats are generally safer than chil‐ dren secured on the front seats. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Occupant safety The generic term child restraint system The generic term child restraint system is used in this Operator's Manual. A child restraint sys‐ tem is, for example: R A baby car seat R A rearward-facing child seat R A forward-facing child seat R A child booster seat with a backrest and seat belt guide Mercedes-Benz recommends using a child booster seat with a backrest. The child restraint system must be appropriate to the age, weight and size of the child. Observe laws and legal requirements Always observe the legal requirements when using a child restraint system in the vehicle. Observe standards for child restraint sys‐ tems All child restraint systems must meet the follow‐ ing standards: R U.S. Federal Motor Vehicle Safety Standards 213 and 225 R Canadian Motor Vehicle Safety Standards 213 and 210.2 Confirmation that the child restraint system complies with the standards can be found on an instruction label on the child restraint system. This confirmation can also be found in the instal‐ lation instructions that are included with the child restraint system. Detecting risks, avoiding danger Securing systems for child restraint systems in the vehicle Only use the following securing systems for child restraint systems: R The LATCH-type (ISOFIX) securing rings R The vehicle's seat belt system R 49 The Top Tether anchorages Installing a LATCH-type (ISOFIX) child restraint system is preferred. Simply attaching to the securing rings on the vehicle can reduce the risk of installing the child restraint system incorrectly. When securing a child with the integrated seat belt of the LATCH-type (ISOFIX) child restraint system, always comply with the permissible gross weight for the child and child restraint sys‐ tem (/ page 53). A booster seat may be necessary to achieve proper seat belt positioning for children over 40 lbs (18 kg) in weight or until they reach a height where a three-point seat belt can be fas‐ tened properly without a booster seat. Mercedes-Benz recommends a suitable child booster seat with a backrest and seat belt guide. Advantage of a rearward-facing child restraint system It is preferable to transport a baby or a small child in a suitable rearward-facing child restraint system. In this case, the child sits in the oppo‐ 50 Occupant safety site direction to the direction of travel and faces backwards. Babies and small children have comparatively weak neck muscles in relation to the size and weight of their head. The risk of injury to the cer‐ vical spine during an accident can be reduced in a rearward-facing child restraint system. Always secure a child restraint system cor‐ rectly & WARNING Risk of injury or death due to incorrect installation of the child restraint system The child can then not be protected or restrained as intended. # Be sure to comply with the manufactur‐ er's installation instructions for the child restraint system and its correct use. # Make sure that the entire base of the child restraint system always rests on the sitting surface of the seat. # # # Never place objects (e.g. cushions) under or behind the child restraint sys‐ tem. Use child restraint systems only with the original cover designed for them. Always replace damaged covers with genuine covers. & WARNING Risk of injury or death due to unsecured child restraint systems in the vehicle If the child restraint system is incorrectly installed or not secured, it can come loose. The child restraint system could be flung around and hit vehicle occupants. # Always install child restraint systems correctly, even when not in use. # Always comply with the child restraint system manufacturer's installation instructions. R Always observe the child restraint system manufacturer's installation and operating R R instructions as well as the vehicle-specific information: Installing the LATCH-type (ISOFIX) child restraint system on the right and left rear seats (/ page 53).

If the front passenger seat is occupied, ensure, both before and during the jour‐ ney, that the status of the front passenger airbag is correct for the cur‐ rent situation (/ page 44). Observe the warning labels in the vehicle interior and on the child restraint system. Also secure Top Tether if present. Occupant safety Do not modify the child restraint system & WARNING Risk of injury due to modifi‐ cations to the child restraint system The child restraint system can no longer function properly. This poses an increased risk of injury. # Never modify a child restraint system. # Only affix accessories which have been specially approved for this child restraint system by the child restraint system's manufacturer. Only use child restraint systems which are in proper working condition & WARNING Risk of injury or death caused by the use of damaged child restraint systems Child restraint systems or their retaining sys‐ tems that have been subjected to stress in an accident may not be able to perform their intended protective function. It may be the case that the child cannot be properly restrained. # Always immediately replace child restraint systems that have been dam‐ aged or involved in an accident. # Have the securing systems for the child restraint systems checked at a qualified specialist workshop before installing a child restraint system again. Avoid direct sunlight & WARNING Risk of burns when the child seat is exposed to direct sunlight If the child restraint system is exposed to direct sunlight or heat, parts could heat up excessively. Children could suffer burns from these parts, particularly the metallic parts of the child restraint system. # Always make sure that the child restraint system is not exposed to direct sunlight. # # # Cover the child restraint system with a blanket, for example. If the child restraint system has been exposed to direct sunlight, allow it to cool before securing a child into it. Never leave children unattended in the vehicle. Observe when stopping or parking & WARNING Risk of accident and injury due to children left unattended in the vehicle If children are left unsupervised in the vehi‐ cle, they could, in particular: R open doors, thereby endangering other persons or road users. R get out and be struck by oncoming traf‐ fic. R operate vehicle equipment and become trapped, for example. 51 52 Occupant safety In addition, the children could also set the vehicle in motion, for example by: R releasing the parking brake. R changing the transmission position. R starting the vehicle. # # # Never leave children unattended in the vehicle. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. Keep the vehicle SmartKey out of reach of children. & WARNING Danger to life due to expo‐ sure to extreme heat or cold in the vehi‐ cle If people, particularly children, are exposed to extreme temperatures over an extended period of time, there is a risk of serious injury or danger to life. # Never leave persons, children in partic‐ ular, unattended in the vehicle.

Full sys‐ Driving and parking 151 R tem effectiveness is not reached until the end of this teach-in process. Brakepads, brake discs and tires that are either new or have been replaced only ach‐ ieve optimum braking effect and grip after several hundred kilometers of driving. Com‐ pensate for the reduced braking effect by applying greater force to the brake pedal. Notes on optimized acceleration If all necessary requirements and activation con‐ ditions are fulfilled, the best possible accelera‐ tion can be achieved from a standstill. Do not use the optimized acceleration on public roads. Individual wheels could spin and you could lose control of the vehicle. There is an increased risk of skidding and/or accident. Be sure to observe the safety notes and informa‐ tion on ESP® (/ page 179). Pulling away with optimized acceleration & WARNING Risk of skidding and having an accident from wheels spinning When you use optimized acceleration, indi‐ vidual wheels could spin and you could lose control of the vehicle. If ESP® is deactivated, there is a risk of skid‐ ding and accident. # Make sure that no persons or obstacles are in the close vicinity of your vehicle. Requirements: R The vehicle has been broken in (/ page 150). R The vehicle and tires are in good condition. R You are on a high-grip roadway. R The engine and transmission are at normal operating temperature. * NOTE Increased wear due to optimized acceleration When pulling away with optimized accelera‐ tion, all components of the drivetrain are subjected to a very high load. This can lead to increased component wear. # Do not always pull away with optimized acceleration. # # # # # # Engage the h drive position (/ page 163). Move the steering wheel to the straightahead position. Select the sportiest available drive program B or C(/ page 160). Deactivate ESP® (/ page 180).

Ending optimized acceleration Remove your foot from the accelerator pedal. # Reactivate the ESP®. % After you pull away with optimized accelera‐ tion, components of the drivetrain can become very hot, which means that opti‐ mized acceleration values may be reached again only after a few minutes. # Notes on driving & WARNING Risk of accident due to objects in the driver's footwell Objects in the driver's footwell may impede pedal travel or block a depressed pedal. This jeopardizes the operating and road safety of the vehicle. # Stow all objects in the vehicle securely so that they cannot get into the driver's footwell. # Always install the floor mats securely and as prescribed in order to ensure that there is always sufficient room for the pedals. # Do not use loose floor mats and do not place floor mats on top of one another. & WARNING Risk of accident due to incor‐ rect footwear Incorrect footwear includes, for example: R Shoes with platform soles R Shoes with high heels R Slippers There is a risk of an accident. Always wear suitable footwear so that you can operate the pedals safely. # & WARNING Risk of accident if the vehicle is switched off while driving If you switch off the vehicle while driving, safety functions are restricted or no longer available. This may affect the power steering system and the brake force boosting, for example. You will need to use considerably more force to steer and brake, for example. # Do not switch off the vehicle while driv‐ ing. & DANGER Risk of death caused by exhaust gases Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases is hazardous to health and leads to poisoning. # Never leave the engine or, if present, the auxiliary heating running in an enclosed space without sufficient venti‐ lation. Driving and parking 153 & WARNING Risk of skidding and of an accident due to shifting down on slippery road surfaces If you shift down on slippery road surfaces to increase the engine braking effect, the drive wheels may lose traction. # Do not shift down on slippery road sur‐ faces to increase the engine braking effect. & DANGER Risk of fatal injury due to poi‐ sonous exhaust gases If the tailpipe is blocked or sufficient ventila‐ tion is not possible, poisonous exhaust gases such as carbon monoxide may enter the vehi‐ cle. This is the case when the vehicle becomes stuck in snow, for example. # Keep the tailpipe and the area around the vehicle free from snow when the engine or the stationary heater are run‐ ning. # Open a window on the side of the vehi‐ cle facing away from the wind to ensure an adequate supply of fresh air. & WARNING Risk of accident and injury due to being under the influence of alco‐ hol and drugs while driving Drinking and driving and/or taking drugs and driving are very dangerous combinations. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judg‐ ment. The possibility of a serious or even fatal acci‐ dent are greatly increased when you drink or take drugs and drive. # Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs. & WARNING Risk of accident due to the brake system overheating If you leave your foot on the brake pedal when driving, the brake system may over‐ heat. This increases the braking distance and the brake system can even fail. # Never use the brake pedal as a footrest. # Do not depress the brake pedal and the accelerator pedal at the same time while driving. * NOTE Engine damage due to excessively high engine speeds The engine will be damaged if you drive with the engine in the overrevving range. # Do not drive with the engine in the over‐ revving range. 154 Driving and parking * NOTE Wearing out the brake linings by continuously depressing the brake pedal # # Do not depress the brake pedal contin‐ uously whilst driving. To use the braking effect of the engine, shift to a lower gear in good time. * NOTE Damage to the drivetrain and engine when pulling away # # Do not warm up the engine while the vehicle is stationary. Pull away immedi‐ ately. Avoid high engine speeds and driving at full throttle until the engine has reached its operating temperature. * NOTE Damage to the catalytic converter due to non-combusted fuel The engine is not running smoothly and is misfiring. Non-combusted fuel may get into the cata‐ lytic converter. # # Only depress the accelerator pedal slightly. Have the cause rectified immediately at a qualified specialist workshop. * NOTE Reduced battery life due to fre‐ quent short-distance trips The 12 V battery may not be sufficiently charged when the vehicle is used only for short-distance trips. This reduces the life of the battery. # Drive longer distances regularly to charge the battery. * NOTE Damage to the vehicle due to not observing the maximum permitted head‐ room clearance If the vehicle height is greater than the maxi‐ mum permitted headroom clearance, the roof and other parts of the vehicle may be damaged. # # # Observe the signposted headroom clearance. If the vehicle height is greater than the permitted headroom clearance, do not enter. Observe the changed vehicle height with add-on roof equipment. Notes on driving with a roof load, trailer or fully laden vehicle When driving with a loaded roof luggage rack or trailer as well as with a fully laden or fully occu‐ pied vehicle, the vehicle's driving and steering characteristics change. You should bear the following in mind: R Do not exceed the permissible roof load and towing capacity. Also observe the technical data in the printed Operator's Manual. R Evenly distribute the roof load, and place heavy objects at the bottom. Also comply with the notes on loading the vehicle (/ page 105). Driving and parking 155 R Drive attentively, and avoid suddenly pulling away, braking and steering as well as rapid cornering. Notes on driving on salt-treated roads The braking effect is limited on salt-treated roads. Therefore, observe the following notes: R Due to salt build-up on the brake discs and brakepads, the braking distance can increase considerably or result in braking only on one side R Maintain a much greater safe distance to the vehicle in front To remove salt build-up: Brake occasionally while paying attention to the traffic conditions R Carefully depress the brake pedal at the end of the journey and when starting the next journey R Notes on hydroplaning Hydroplaning can take place once a certain amount of water has accumulated on the road surface. Observe the following notes during heavy precip‐ itation or in conditions in which hydroplaning may occur: R Reduce speed R Avoid tire ruts R Avoid sudden steering movements R Brake carefully % Also observe the notes on regularly checking wheels and tires (/ page 322). Notes on driving through water on the road surface Water which has entered into the vehicle can damage the engine, electrics and transmission. Water can also enter the air intake of the engine and cause engine damage. Observe the following if you must drive through water: R The water, when calm, may only reach the lower edge of the vehicle body. R Drive at a maximum speed of 6 mph (10 km/h); water can otherwise enter the vehicle interior or engine compartment. R Vehicles traveling in front, or oncoming vehi‐ cles, can create waves which may exceed the maximum permissible depth of the water. The braking effect of the brakes is reduced after fording. Brake carefully while paying attention to the traffic conditions until braking power has been fully restored. Function of rear axle steering The rear axle steering is an electromechanical auxiliary steering on the rear axle which adjusts the steering of the rear wheels according to the position of the front wheels, depending on the speed. This results in greater maneuverability and improved driving stability, e.g. when corner‐ ing. 156 Driving and parking ECO start/stop function ECO start/stop function % Depending on the engine, the ECO start/ stop function is not available in all drive pro‐ grams.

The ECO display assesses the following criteria for an economical driving style: R Coasting at the right time R Consistent speed R Moderate acceleration The overall assessment of your driving style "from start" is indicated using stars. It starts with five empty stars, which you can fill one after the other if you drive efficiently. When all five stars are filled, a glow appears in the back‐ ground. % You can call up the ECO Display function via the Classic and Exclusive menus (/ page 239). 158 Driving and parking ECO Assist function (vehicles with 48 V onboard electrical system) % ECO Assist is active only in drive pro‐ grams ; and A. ECO Assist analyzes data for the vehicle's expec‐ ted route. This allows the system to optimally adjust the driving style for the route ahead, save fuel and recuperate. If the system detects an event ahead and the vehicle nears the event, ECO Assist will calculate the optimum speed for maximum fuel economy and recuperative energy based on the distance, speed and downhill gradi‐ ent. 1 "Foot off the accelerator" recommendation 2 Route event ahead If a route event that can be dealt with more effi‐ ciently by adjusting your driving style is detected ahead, corresponding symbol 2 and the ý symbol will be displayed in gray. When the driver removes their foot from the accelerator, the ý symbol will turn green. The display will disappear as soon as ECO Assist cannot identify any further recommendations from the route ahead. The following route events can be detected by ECO Assist: 3 Roundabout 4 S-curve 5 Sharp curve 6 T-intersection 7 Downhill gradient 8 Vehicle in front 9 Speed limit % Only route event 8 "vehicle in front" will be displayed in drive program A. Driving and parking 159 System limits If the calculated route is adhered to when route guidance is active, ECO Assist will operate with greater accuracy. The basic function is also available without active route guidance. Not all information and traffic situations can be fore‐ seen. The quality depends on the map data. ECO Assist is only an aid. The driver is responsi‐ ble for keeping a safe distance from the vehicle in front, for vehicle speed and for braking in good time. The system may be impaired or may not function in the following situations: R If there is poor visibility, e.g. due to insuffi‐ cient illumination of the road, highly variable shade conditions, rain, snow, fog or heavy spray. R If there is glare, e.g. from oncoming traffic, direct sunlight or reflections. R If the windshield in the area of the multifunc‐ tion camera is dirty, or if the camera is fog‐ ged up, damaged or covered. R R R If the traffic signs are hard to detect, e.g. due to dirt, snow or insufficient lighting, or because they are covered. If the information in the navigation system's digital map is incorrect or out-of-date. If signs are ambiguous, e.g. road signs in roadworks or in adjacent lanes.

Driving and driving safety systems Driving systems and your responsibility Your vehicle is equipped with driving systems which assist you in driving, parking and maneu‐ vering the vehicle. The driving systems are only aids. They are not a substitute for your attention to the surroundings and do not relieve you of your responsibility pertaining to road traffic law. The driver is always responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Pay attention to the traffic conditions at all times and intervene when necessary. Be aware of the limitations regarding the safe use of these systems. Driving systems can neither reduce the risk of accident if you fail to adapt your driving style nor override the laws of physics. They cannot always take into account road, weather or traffic condi‐ tions. Information on vehicle sensors and cameras Some driving and driving safety systems use cameras as well as radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle. 1 Multifunction camera 2 Cameras in the outside mirrors Driving and parking 177 3 4 5 6 7 Front radar Front camera Corner radars Ultrasonic sensors Rear view camera & WARNING Risk of accident due to restricted detection performance of vehi‐ cle sensors and cameras If the area around vehicle sensors or cam‐ eras is covered, damaged or dirty, certain driving and safety systems cannot function correctly. There is a risk of an accident. # Keep the area around vehicle sensors or cameras clear of any obstructions and clean. # Have damage to the bumper, radiator grille or stone chipping in the area of the front and rear windows repaired at a qualified specialist workshop. Particularly, keep the areas around the sensors and cameras free of dirt, ice or slush (/ page 298). The sensors and cameras must not be covered and the detection ranges around them must be kept free. Do not attach additional license plate brackets, advertisements, stickers, decorative foils or foils to protect against stone chippings in the detection range of the sensors and cameras. Make sure that there are no over‐ hanging loads protruding into the detection range. If there is damage to a bumper or the radiator grille, or after an impact, have the function of the sensors checked at a qualified specialist workshop. Have damage or stone chipping in the area of the cameras on the windshield and rear window repaired at a qualified specialist work‐ shop. % The rear view camera can extend and retract automatically for the purpose of calibration, even though there is no camera image in the display.

R Rear view camera (/ page 217) R Surround view camera (/ page 220) R Parking Assist PARKTRONIC (/ page 225) R Active Parking Assist (/ page 229) Functions of ABS The Anti-lock Brake System (ABS) regulates the brake pressure in critical driving situations: R During braking, for instance, at maximum full-stop braking or if there is insufficient tire traction, the wheels are prevented from lock‐ ing. R Vehicle steerability while braking is ensured. 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 can serve as a reminder to take extra care while driving. System limits R ABS is active from speeds of approx. 3 mph (5 km/h). R ABS may be impaired or may not function if a malfunction has occurred and the yel‐ low ! ABS warning lamp lights up contin‐ uously in the instrument cluster after the vehicle is started. Function of BAS & WARNING Risk of an accident caused by a malfunction in BAS (Brake Assist Sys‐ tem) If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. Driving and parking 179 # Depress the brake pedal with full force in emergency braking situations. ABS prevents the wheels from locking. The Brake Assist System (BAS) supports your emergency braking situation with additional brake force. If you depress the brake pedal quickly, BAS is activated: R BAS automatically boosts the brake pres‐ sure. R BAS can shorten the braking distance. R ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. Function of ESP® & WARNING Risk of skidding if ESP® is deactivated If you deactivate ESP®, ESP® cannot carry out vehicle stabilization. # ESP® should only be deactivated in the following situations. The Electronic Stability Program (ESP®) can monitor and improve driving stability and trac‐ tion in the following situations within physical limits: R When pulling away on wet or slippery road. R When braking. If the vehicle deviates from the direction desired by the driver, ESP® can stabilize the vehicle by intervening in the following ways: R One or more wheels are braked. R The engine output is adapted according to the situation. When ESP® is deactivated, the å warning lamp lights up continuously: R Driving stability will no longer be improved. R The drive wheels could spin. R ETS/4ETS traction control is still active. % When ESP® is deactivated, you are still assis‐ ted by ESP® when braking. When the ÷ warning lamp flashes, one or several wheels has reached its grip limit: R Adapt your driving style to suit the current road and weather conditions. R Do not deactivate ESP®. R Only depress the accelerator pedal as far as is necessary when pulling away. Deactivate ESP® in the following situations to improve traction: R When using snow chains. R In deep snow. R On sand or gravel. % Spinning the wheels results in a cutting action, which enhances traction. If the ÷ ESP® warning lamp lights up continu‐ ously, ESP® is not available due to a malfunction. Observe the following information: R Warning and indicator lamps (/ page 424) R Display messages (/ page 367) 180 Driving and parking ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP® and makes it possible to pull away and accelerate on a slippery road. ETS/4ETS can improve the vehicle's traction by intervening in the following ways: R The drive wheels are braked individually if they spin. R More drive torque is transferred to the wheel or wheels with traction. Influence of drive programs on ESP® The drive programs enable ESP® to adapt to dif‐ ferent weather and road conditions as well as the driver's preferred driving style. Depending on the selected drive program, the appropriate ESP® mode will be activated. You can select the drive programs using the DYNAMIC SELECT switch (/ page 160). Function of ESP® Crosswind Assist ESP® Crosswind Assist detects sudden gusts of side wind and helps the driver to keep the vehi‐ cle in the lane: R ESP® Crosswind Assist is active at vehicle speeds between approx. 47 mph (75 km/h) and 125 mph (200 km/h) when driving straight ahead or cornering slightly. R The vehicle is stabilized by means of individ‐ ual brake application on one side.

ESP® is deactivated if the å ESP® OFF warn‐ ing lamp lights up continuously in the driver dis‐ play. Observe any information on warning lamps and display messages which may be shown in the driver display. Function of EBD Electronic Breakforce Distribution (EBD) is char‐ acterized by the following: R Monitoring and regulating the brake pressure on the rear wheels. R Improved driving stability when braking, especially on bends. Function of STEER CONTROL STEER CONTROL assists you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization. This steering recommendation is given in the fol‐ lowing situations: R Both right wheels or both left wheels are on a wet or slippery road surface when you brake R The vehicle starts to skid Driving and parking 181 System limits STEER CONTROL may be impaired or may not function in the following situations: R ESP® is deactivated. R ESP® is malfunctioning. R The steering is malfunctioning. If ESP® is malfunctioning, you will be assisted further by the electric power steering. HOLD function HOLD function The HOLD function holds the vehicle at a stand‐ still without requiring you to depress the brake pedal, e.g. while waiting in traffic. The HOLD function is only an aid. The responsi‐ bility for the vehicle safely standing still remains with the driver. System limits The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary. R The incline must not be greater than 30%. R Activating/deactivating the HOLD function & WARNING Risk of an accident due to the HOLD function being active when you leave the vehicle If the vehicle is only braked with the HOLD function it could, in the following situations, roll away: R If there is a malfunction in the system or in the power supply. R If the HOLD function is deactivated by depressing the accelerator pedal or brake pedal, e.g. by a vehicle occupant. # Always secure the vehicle against roll‐ ing away before you leave it. Requirements: R The vehicle is stationary. R The driver's door is closed or the seat belt on the driver's side is fastened. R R R The vehicle has been started or has been automatically switched off by the ECO start/ stop function. The electric parking brake is released. Active Distance Assist DISTRONIC is deacti‐ vated. The transmission is in position h, k or i. Activating the HOLD function # Depress the brake pedal, and after a short time quickly depress further until the ë display appears in the driver's display. # Release the brake pedal. Deactivating the HOLD function # Depress the accelerator pedal to pull away. or # Depress the brake pedal until the ë dis‐ play disappears from the driver's display. The HOLD function is deactivated in the follow‐ ing situations: R Active Distance Assist DISTRONIC is activa‐ ted. 182 Driving and parking R R The transmission is shifted to position j. The vehicle is secured with the electric park‐ ing brake. In the following situations, the vehicle is held by transmission position j and/or by the electric parking brake: R The seat belt is unfastened and the driver's door is opened. R The vehicle is switched off. R There is a system malfunction. R The power supply is insufficient. In addition, the Brake Immediately message may appear in the driver's display and a horn tone may sound at regular intervals. # Immediately depress the brake pedal firmly until the warning message disappears. The HOLD function is deactivated. # Additionally secure the vehicle against rolling away. Function of Hill Start Assist ATTENTION ASSIST Hill Start Assist holds the vehicle for a short time when pulling away on a hill under the fol‐ lowing conditions: R The transmission is in position h or k. R The electric parking brake is released. Function of ATTENTION ASSIST ATTENTION ASSIST assists you on long, monoto‐ nous journeys, e.g. on highways and trunk roads. If indicators of fatigue or increasing lapses in concentration on the part of the driver are detected, the system suggests taking a break. ATTENTION ASSIST is only an aid. It cannot always detect fatigue or lapses in concentration in time. The system is not a substitute for a wellrested and attentive driver. On long journeys, take regular breaks in good time that allow for adequate recuperation. You can choose between two settings: R Standard: normal system sensitivity. R Sensitive: higher system sensitivity. The driver is warned earlier and the attention level detected by ATTENTION ASSIST is adap‐ ted accordingly. This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to roll away. & WARNING Risk of accident and injury due to the vehicle rolling away After a short time, Hill Start Assist no longer holds the vehicle. # Swiftly move your foot from the brake pedal to the accelerator pedal. Do not leave the vehicle when it is being held by Hill Start Assist. If drowsiness or increasing lapses in concentra‐ tion are detected, the ATTENTION ASSIST: Take a Break! warning appears in the driver display. You can acknowledge the message and take a Driving and parking 183 break where necessary. If you do not take a break and ATTENTION ASSIST continues to detect increasing lapses in concentration, you will be warned again after a minimum of 15 minutes. The following information is displayed in the driver display: R The length of the journey since the last break R The attention level determined by ATTENTION ASSIST: The more segments 1 of the circle dis‐ played, the higher the detected attention level. - Fewer segments 1 are displayed in the circle as the attention level decreases. If ATTENTION ASSIST is unable to calculate the attention level and cannot issue a warning, the System Suspended message appears. If a warning is given in the driver display, the multimedia system offers to search for a rest area. You can select a rest area and start naviga‐ tion to this rest area. If you restart the vehicle, ATTENTION ASSIST with microsleep detection is automatically acti‐ vated. The last selected sensitivity level remains stored. System limits ATTENTION ASSIST is active in the 37 mph (60 km/h) to 124 mph (200 km/h) speed range. Particularly in the following situations, ATTEN‐ TION ASSIST only functions in a restricted man‐ ner and warnings may be delayed or not occur: R If you have been driving for less than approx‐ imately 30 minutes. R If the road condition is poor (uneven road surface or potholes). R R R R R If there is a strong side wind. If you adopt a sporty driving style (high cor‐ nering speeds or high rates of acceleration). If the Steering Assist function of Active Dis‐ tance Assist DISTRONIC is active. If the clock is set to the incorrect time. If you change lanes and vary your speed fre‐ quently in active driving situations. Also observe any information regarding display messages that can be displayed in the driver dis‐ play. The ATTENTION ASSIST drowsiness or alertness assessment is reset and restarted when continu‐ ing the journey in the following situations: R You switch off the vehicle. R If you unfasten your seat belt and open the driver's door (e.g. to change drivers or take a break). 184 Driving and parking Setting ATTENTION ASSIST Multimedia system: 4 © 5 Settings 5 Assistance 5 Assistance 5 ATTENTION ASSIST Displays on the driver display h (gray): cruise control is selected but not yet active, or temporarily passive. R h (green): cruise control is active. Setting the sensitivity Tap the current setting. # Select Standard or Sensitive. A stored speed appears under the h display and is indicated in the speedometer. # Speed control cruise control Function of cruise control Cruise control regulates the speed to the value selected by the driver. If you accelerate to overtake, for example, the stored speed is not deleted. If you remove your foot from the accelerator pedal after overtaking, cruise control will resume speed regulation back to the stored speed. You can store any speed above 15 mph (20 km/h) up to the maximum design speed. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). R R System limits Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle. By doing so, you will make use of the engine's brak‐ ing effect. This relieves the load on the brake system and prevents the brakes from overheat‐ ing and wearing too quickly. Do not use cruise control in the following situa‐ tions: R In traffic situations which require frequent changes of speed, e.g. in heavy traffic, on winding roads. R On slippery roads. Accelerating can cause the drive wheels to lose traction and the vehicle could then skid. If you are driving when visibility is poor. Operating cruise control & WARNING Risk of accident due to stored speed If you call up the stored speed and this is lower than your current speed, the vehicle decelerates. # Take into account the traffic situation before calling up the stored speed.

Active Distance Assist DISTRONIC Function of Active Distance Assist DISTRONIC Active Distance Assist DISTRONIC maintains the set speed on free-flowing roads. If vehicles in front are detected, the set distance is main‐ tained, if necessary, until the vehicle comes to a halt. The vehicle accelerates or brakes depend‐ ing on the distance to the vehicle in front and the set speed. The speed and distance to the vehicle in front are set and saved using the steering wheel. Available speed range: R Vehicles without Driving Assistance Pack‐ age: 15 mph (20 km/h) - 100 mph (160 km/h) R Vehicles with Driving Assistance Pack‐ age: 15 mph (20 km/h) - 130 mph (210 km/h) Other features of Active Distance Assist DISTRONIC: R Adjusts the driving style depending on the selected drive program (fuel-saving, comfort‐ able or dynamic) (/ page 159) R Initiates acceleration to the stored speed if the turn signal indicator is switched on to change to the overtaking lane R Vehicles with Driving Assistance Pack‐ age: Reacts to stationary vehicles detected in urban speed ranges (except bicycles and motorcycles) Takes one-sided overtaking restrictions into account on highways or on multi-lane roads with separate roadways (countrydependent) % In the DYNAMIC SELECT menu, the driving style of Active Distance Assist DISTRONIC can be set. Depending on which drive pro‐ gram is selected, the driving characteristics can be geared towards energy economy, comfort or dynamic performance. In the Active Distance Assist menu, the driving style can be permanently set to Comfort or Dynamic (/ page 192). Vehicles with Active Parking Assist and Driv‐ ing Assistance Package: if Active Distance Assist DISTRONIC has braked the vehicle to a standstill, it can automatically follow the vehicle in front when driving off again within 30 sec‐ onds. If a critical situation is detected in the sur‐ rounding area when driving off, such as a person in the vehicle path, a visual and acoustic warning is given indicating that the driver must now take control of the vehicle. The vehicle is not acceler‐ ated any further. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). Driving and parking 187 Display in the driver display in the Assistance menu 1 Vehicle in front 2 Distance indicator 3 Set specified distance Vehicle detected in front 1 is highlighted in green.

R The windshield in the area of the camera is dirty, fogged up, damaged or covered. R If the radar sensors are dirty or covered. R In parking garages or on roads with steep uphill or downhill gradients. R If there are narrow vehicles in front, such as bicycles or motorcycles. In addition, on slippery roads, braking or accel‐ erating can cause one or several wheels to lose traction and the vehicle could then skid. Do not use Active Distance Assist DISTRONIC in these situations. 188 Driving and parking & WARNING Risk of accident from acceler‐ ation or braking by Active Distance Assist DISTRONIC & WARNING Risk of accident due to insuf‐ ficient deceleration by Active Distance Assist DISTRONIC R Active Distance Assist DISTRONIC may accel‐ erate or brake in the following cases, for example: R If the vehicle pulls away using Active Dis‐ tance Assist DISTRONIC. R If the stored speed is called up and is considerably faster or slower than the currently driven speed. R If Active Distance Assist DISTRONIC no longer detects a vehicle in front or does not react to relevant objects. Active Distance Assist DISTRONIC brakes your vehicle with up to 50% of the possible deceleration. If this deceleration is not suffi‐ cient, Active Distance Assist DISTRONIC alerts you with a visual and acoustic warning. # Adjust your speed and maintain a suita‐ ble distance from the vehicle in front. # Brake the vehicle yourself and/or take evasive action. R # # Always carefully observe the traffic con‐ ditions and be ready to brake at all times. Take into account the traffic situation before calling up the stored speed. & WARNING Risk of accident if detection function of Active Distance Assist DISTRONIC is impaired Active Distance Assist DISTRONIC does not react or has a limited reaction: R when driving on a different lane or when changing lanes R to pedestrians, animals, bicycles or sta‐ tionary vehicles, or unexpected obstacles to complex traffic conditions to oncoming vehicles and crossing traffic As a result, Active Distance Assist DISTRONIC may neither give warnings nor intervene in such situations. # Always observe the traffic conditions carefully and react accordingly.

Deactivating Active Distance Assist DISTRONIC & WARNING Risk of an accident due to Active Distance Assist DISTRONIC being active when you leave the driver's seat If you leave the driver's seat while the vehicle is being braked by Active Distance Assist DISTRONIC only, the vehicle can roll away. # Always deactivate Active Distance Assist DISTRONIC and secure the vehi‐ cle to prevent it from rolling away before you leave the driver's seat. # Press ±. % If you brake, deactivate ESP® or if ESP® intervenes, Active Distance Assist DISTRONIC is deactivated. Function of Active Speed Limit Assist If a change in the speed limit of 12 mph (20 km/h) or more is detected and automatic adoption of speed limits is activated, the new speed limit is automatically adopted as the stored speed (/ page 192). The driven speed is adjusted when the vehicle is level with the traffic sign at the latest. In the case of signs indicating entry into an urban area, the speed is adapted according to the speed permitted within the urban area. The speed limit display in the driver display is always updated when the vehicle is level with the traffic sign. If you are driving on German highways and there is no speed limit, the system uses the speed stored for a stretch of road with no speed limit as the set speed. If you do not alter the stored speed on a stretch of road with no speed limit, the recommended speed of 80 mph (130 km/h) is adopted. If Active Distance Assist DISTRONIC has been put into passive mode by pressing the accelera‐ tor pedal, only speed limits which are higher than the set speed are adopted. The maximum permissible speed does not take the road condition and current weather and traf‐ fic conditions into account. Adjust your speed accordingly, when necessary. Driving and parking 191 Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). System limits The system limits of Traffic Sign Assist apply to the detection of traffic signs (/ page 205). Speed limits below 12 mph (20 km/h) are not automatically adopted by the system as the stored speed. Temporary speed restrictions (e.g. for a certain time or due to weather conditions) cannot be properly detected by the system. The maximum permissible speed applying to a vehi‐ cle with a trailer is not detected by the system. Adjust the speed in these situations. & WARNING Risk of accident due to Active Speed Limit Assist adapting the vehicle's speed The speed adopted by Active Speed Limit Assist may be too high or incorrect in some individual cases, such as: R at speed limits below 12 mph (20 km/h) R R # # in wet conditions or in fog when towing a trailer Ensure that the driven speed complies with traffic regulations. Adjust the driving speed to suit current traffic and weather conditions. Function of route-based speed adaptation When Active Distance Assist DISTRONIC is acti‐ vated, the vehicle speed will be adapted accord‐ ingly to the route events ahead. Depending on the drive program selected, the vehicle negoti‐ ates a route event ahead in a fuel-saving, com‐ fortable or dynamic manner. When the route event has been passed, the vehicle accelerates again to the stored speed. The set distance to the vehicle in front, vehicles detected ahead and speed restrictions ahead are taken into account. Route-based speed adaptation can be activated in the multimedia system (/ page 192). The following route events are taken into account: R Curves R R R R Roundabouts T-intersections Turns and exits Traffic jams ahead (only with Live Traffic ) Also, the speed is reduced if the turn signal indi‐ cator is switched on and one of the following sit‐ uations is detected: R Turning off at intersections R Driving on slowing-down lanes R Driving on lanes adjacent to slowing-down lanes The driver is responsible for choosing the right speed and observing other road users. This applies in particular to intersections, round‐ abouts and traffic lights, as route-based speed adaptation does not brake the vehicle to a stand‐ still. If a corresponding route event is detected while route guidance is active, the first speed adjust‐ ment is carried out automatically. If the turn sig‐ nal indicator is switched on, the selected route is 192 Driving and parking confirmed and further speed adjustment is acti‐ vated. Speed adaptation is canceled in the following cases: R If the turn signal indicator is switched off before the route event and it is therefore assumed that the route event is not relevant to the driver. R If the driver depresses the accelerator or brake pedal during the process. System limits Route-based speed adaptation does not take right of way regulations into account. The driver is responsible for complying with road traffic regulations and driving at a suitable speed. In difficult conditions, the speed selection made by the system may not always be suitable. This applies to the following situations, for example: R Unclear roads R Road narrowing R Varying maximum permissible speeds in indi‐ vidual lanes, for example at toll stations R Wet road surfaces, snow or ice In these situations the driver must intervene accordingly. & WARNING Risk of accident in spite of route-based speed adaptation Route-based speed adaptation can malfunc‐ tion or be temporarily unavailable in the fol‐ lowing situations: R If the driver does not follow the calcula‐ ted route R If map data is not up-to-date or available R In the event of roadworks R In bad weather or road conditions R If the accelerator pedal is depressed R In the event of electronically displayed speed limitations # Adapt the speed to the traffic situation.

Function of Active Stop-and-Go Assist Active Stop-and-Go Assist helps you when in traffic jams on multi-lane roads with separate roadways by automatically pulling away within up to 60 seconds and with moderate steering maneuvers. It orients itself using the vehicle in front and lane markings. Active Stop-and-Go Assist automatically maintains a safe distance from the vehicle in front and vehicles cutting in. Active Stop-and-Go Assist requires you, as the driver, to keep your hands on the steering wheel at all times so that you are able to intervene at any time to correct the course of the vehicle and keep it in lane. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). Active Stop-and-Go Assist activates automati‐ cally when all of the following conditions are met: R You are in a traffic jam on a freeway or highspeed major road. R Active Distance Assist DISTRONIC is activa‐ ted and active (/ page 188). R Active Steering Assist is activated and active (/ page 195). R You are traveling no faster than 35 mph (60 km/h).

Active Steering Assist Function of Active Steering Assist Active Steering Assist is only available up to a speed of 130 mph (210 km/h). The system helps you to stay in the center of the lane by means of moderate steering interventions. Depending on the speed driven, Active Steering Assist uses the vehicles ahead and lane markings as a refer‐ ence. % Depending on the country, in the lower speed range Active Steering Assist can use the surrounding traffic as a reference. If nec‐ essary, Active Steering Assist can then also provide assistance when driving away from the center of the lane. If the detection of lane markings and vehicles ahead is impaired, Active Steering Assist switches to passive mode. The system provides no support in this case.

Dis‐ play 1 appears in the driver display. If the driver still does not steer the vehicle, or gives no confirmation to the system, a warning tone sounds in addition to the visual warning mes‐ sage. If the driver does not react to this warning for a considerable period, an emergency stop is initi‐ ated (/ page 195). The warning is not issued or is stopped as soon as the system detects that the driver has touched the steering wheel. Touch detection may be limited or inoperative in the following situations: R The driver is wearing gloves. R There is a steering wheel cover on the steer‐ ing wheel. If Active Steering Assist detects that a system limit has been reached, a visual warning is issued and a warning tone sounds. If the system detects that the driver has not steered the vehicle for a considerable period of Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). System limits Active Steering Assist has a limited steering tor‐ que for lateral guidance. In some cases, the steering intervention is not sufficient to keep the vehicle in the lane. The system may be impaired or may not function in the following instances: R There is poor visibility, e.g. due to snow, rain, fog, heavy spray, greatly varying ambient light or strong shadows on the road.

Function of Active Emergency Stop Assist Depending on vehicle equipment, Active Emer‐ gency Stop Assist uses touch sensors or detects steering movements when monitoring the steer‐ ing wheel. If the system detects that the driver is no longer holding the steering wheel, it can ini‐ tiate an emergency stop, if necessary. Vehicles without Driving Assistance Pack‐ age: the accelerator and brake pedal are moni‐ tored as well as the steering wheel. 196 Driving and parking Vehicles with Driving Assistance Package: if Active Steering Assist is deactivated, the accel‐ erator and brake pedal are monitored as well as the steering wheel. A warning is issued when the steering wheel is not being held or when a pedal is not depressed, and the vehicle is in danger of leaving the lane. If the system detects that the driver has not steered the vehicle for a considerable period of time or has removed their hands from the steer‐ ing wheel, visual warning 1 is issued. If the driver still does not steer the vehicle, or gives no confirmation to the system, a warning tone sounds in addition to the visual warning mes‐ sage. Also observe the instructions on the contact detection of Active Steering Assist (/ page 193). Active Emergency Stop Assist issues the follow‐ ing warnings in order: R Display message 1 appears in the driver display. R In addition to display 1 a warning tone sounds. R The Beginning Emergency Stop message appears in the driver display, a continuous warning tone sounds, the vehicle no longer accelerates, and there is a slight, repeated tensioning of the seat belt. R The vehicle speed is reduced in increments until it is at a standstill. Sharp brake impul‐ ses are also produced. Vehicles with Driving Assistance Package: depending on the country, a lane change to the adjacent right-hand lane is carried out, if possi‐ ble. % It is only possible to change across one lane and only into the right-hand lane, and not onto the hard shoulder. When automatic braking is initiated, Active Dis‐ tance Assist DISTRONIC is deactivated. Depend‐ ing on the country, the hazard warning light sys‐ tem is switched on. When the vehicle is stationary, the following actions are carried out: R The vehicle is secured with the electric park‐ ing brake. R The vehicle is unlocked. R If possible, an emergency call is placed to the Mercedes-Benz emergency call center. Before automatic braking is initiated, you can cancel Active Emergency Stop Assist by steer‐ ing. You can cancel the intervention by Active Emer‐ gency Stop Assist after automatic braking is ini‐ tiated by one of the following actions: R Accelerating or braking: the emergency stop is canceled, but the warning message, warn‐ ing tone and power steering remain active Driving and parking 197 R Steering: power-assisted steering is can‐ celed, the warning message and warning tone remain active and the vehicle continues to be braked % Active Emergency Stop Assist can initiate an emergency stop a maximum of three times within one driving cycle. Subsequently, Active Steering Assist and Active Emergency Stop Assist are deactivated for that driving cycle. System limits Vehicles without Driving Assistance Pack‐ age: if Active Lane Keeping Assist does not detect lane markings or is deactivated, Active Emergency Stop Assist is not active. Vehicles with Driving Assistance Package: if Active Lane Keeping Assist does not detect lane markings, Active Emergency Stop Assist is not active. For the detection of vehicles and other obsta‐ cles, observe the system limits of the following functions: R Active Distance Assist DISTRONIC (/ page 186) R Active Steering Assist (/ page 193) R Active Lane Change Assist (/ page 197) Active Lane Change Assist Function of Active Lane Change Assist Active Lane Change Assist supports the driver when changing lanes and is activated by indicat‐ ing briefly. For this, the following conditions must be fulfil‐ led: R You are on a freeway or high-speed major road. R The vehicle speed is between approximately 45 mph (70 km/h) and 110 mph (180 km/h). R The neighboring lane is separated by a bro‐ ken lane marking. R R R No vehicle or obstacle is detected in the adjacent lane. Active Lane Change Assist is selected in the multimedia system. Active Distance Assist DISTRONIC and Active Steering Assist are switched on and active. 198 Driving and parking Display in the driver display in the Assistance menu 1 Green arrow: lane change initiated 2 Red arrow: lane change canceled When Active Lane Change Assist is available, the ± display appears along with green arrows in the driver display. If the system has been activa‐ ted but is not currently available, the ± dis‐ play appears along with gray arrows in the driver display. If no vehicle or obstacle is detected in the adja‐ cent lane and a lane change is permitted, the lane change begins after the driver has indicated briefly. The lane change is shown to the driver with a flashing green arrow next to the ± steering wheel symbol. Green arrow 1 is dis‐ played in the appropriate adjacent lane in the Assistance menu in the driver display. The Lane Change to the Left message, for example, also appears. If a lane change is not possible directly after the driver has activated the turn signal indicator because an obstacle has been detected, for example, the arrow will also flash in green next to the ± steering wheel symbol and the neighboring lane will continue to be monitored. When the lane becomes free, a lane change will be carried out and the Lane Change to the Left message, for example, appears in the driver dis‐ play. If the green arrows stop flashing, the lane change must be activated again. Active Lane Change Assist can be canceled in various situations, including the following: R Change in the surrounding conditions (e.g. detected obstacle). R The driver steers with too much force or in the opposite direction. R The driver moves the turn signal indicator in the opposite direction. R Active Distance Assist DISTRONIC or Active Steering Assist is deactivated. R The vehicle cannot make the lane change as planned. Cancellation of Active Lane Change Assist is dis‐ played as follows: R The arrow in the selected direction of travel turns red. R A corresponding message will also appear in the driver display. R In certain circumstances a warning tone sounds. Driving and parking 199 & WARNING Risk of accident when chang‐ ing lane to an occupied adjacent lane Lane Change Assist cannot always clearly detect if the adjacent lane is free. The lane change might be initiated although the adjacent lane is not free. # Before changing lanes, make sure that the neighboring lane is free and there is no danger to other road users. # Monitor the lane change. & WARNING Risk of accident if Lane Change Assist unexpectedly stops func‐ tioning If the system limitations for Lane Change Assist have been reached, there is no guar‐ antee that the system will remain active. Lane Change Assist cannot then assist you by applying steering torque. # Always monitor the lane change and keep your hands on the steering wheel. Observe the traffic conditions and steer and/or brake if necessary. System limits The system limitations of Active Steering Assist apply to Active Lane Change Assist (/ page 193). The system may also be impaired or may not function in the following situations: R The sensors are damaged, covered or dirty (/ page 176). R The exterior lighting shows a defect. R The system does not detect a suitable road, for example, in tight curves. R The vehicle is on a construction site. % The Active Lane Change Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Lane Change Assist is unavailable or only partially available during this teach-in process, and no arrows are dis‐ played next to the Ø Active Steering Assist symbol. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). Selecting Active Lane Change Assist Multimedia system: 4 © 5 Settings 5 Assistance 5 Driving # Select the function. Active Brake Assist Function of Active Brake Assist Active Brake Assist consists of the following functions: R Distance warning function R Autonomous braking function R Situation-dependent braking assistance R Vehicles with Driving Assistance Pack‐ age: Evasive Steering Assist (country-spe‐ cific) Active Brake Assist can help you to minimize the risk of a collision with vehicles, cyclists or 200 Driving and parking pedestrians or to reduce the effects of such a collision. If Active Brake Assist has detected a risk of colli‐ sion, a warning tone sounds and the L dis‐ tance warning lamp lights up. In the Assistance menu, an insufficient distance 1 to the vehicle in front is displayed in red. If you further reduce the distance, the vehicle in front is also highlighted in red. When the system detects a risk of collision, red radar waves 2 appear in front of the vehicle. Vehicles with PRE-SAFE®: depending on the country, an additional haptic warning occurs in the form of slight, repeated tensioning of the seat belt. % Vehicles with active ambient lighting: if Warning Support is activated, the Active Brake Assist warning is also accompanied by ambient lighting (/ page 130). If you do not react to the warning, autonomous braking can be initiated in critical situations. In particularly critical situations, Active Brake Assist can also initiate autonomous braking directly. In this case, the warning lamp and warn‐ ing tone occur simultaneously with the braking application. If you apply the brake yourself in a critical situa‐ tion or apply the brake during autonomous brak‐ ing, situation-dependent braking assistance occurs. The brake pressure increases up to max‐ imum full-stop braking if necessary. If autonomous braking or situation-dependent braking assistance has occurred, pop up 1 appears in the driver's display and then automat‐ ically goes out after a short time. If the autonomous braking function or the situa‐ tion-dependent braking assistance is triggered, additional preventive measures for occupant protection (PRE-SAFE®) may also be initiated. Driving and parking 201 & WARNING Risk of an accident caused by limited detection performance of Active Brake Assist Active Brake Assist cannot always clearly identify objects and complex traffic situa‐ tions. In such cases, Active Brake Assist might: R Give a warning or brake without reason R Not give a warning or not brake Active Brake Assist is only an aid. The driver is responsible for maintaining a sufficiently safe distance to the vehicle in front, vehicle speed and for braking in good time. # Always pay careful attention to the traf‐ fic situation; do not rely on Active Brake Assist alone. # Be prepared to brake or swerve if nec‐ essary. % If Active Brake Assist is deactivated, æ appears in the driver's display. If the system is unavailable or the functions are restricted, Ä appears. Also observe the system limits of Active Brake Assist. The individual subfunctions are available in the following speed ranges: The distance warning function issues a warning in the following situations: R From approximately 4 mph (7 km/h) if your vehicle is critically close to a vehicle, cyclist or pedestrian, you will hear an intermittent warning tone and the L distance warning lamp lights up in the driver's display. Vehicles with PRE-SAFE®: depending on the country, an additional haptic warning occurs in the form of slight, repeated ten‐ sioning of the seat belt. If possible, brake immediately or maneuver to avoid the obstacle. Distance warning function The distance warning function can aid you in the following situations with an intermittent warning tone and a warning lamp: Vehicles without Driving Assistance Package: At speeds up to approximately 155 mph (250 km/h) when approaching vehicles ahead.

Canceling a brake application of Active Brake Assist You can cancel a brake application of Active Brake Assist at any time by: R Fully depressing the accelerator pedal or with kickdown. R Releasing the brake pedal. Active Brake Assist may cancel the brake appli‐ cation when one of the following conditions is fulfilled: R You maneuver to avoid the obstacle R There is no longer a risk of collision R An obstacle is no longer detected in front of your vehicle Reaction to oncoming road users (only vehi‐ cles with Driving Assistance Package) Active Brake Assist can also react to detected oncoming road users: R Reaction up to speeds of approximately 62 mph (100 km/h) R Warning for oncoming road users through acoustic warning and warning lamp R Autonomous braking application in order to reduce the severity of an accident Evasive Steering Assist (only vehicles with Driving Assistance Package) & WARNING Risk of accident despite Eva‐ sive Steering Assist Evasive Steering Assist cannot always recog‐ nize objects or complex traffic situations clearly. Moreover, the steering support provided by Evasive Steering Assist is not sufficient to avoid a collision. # # # # Always pay careful attention to the traf‐ fic situation; do not rely on Evasive Steering Assist alone. Be prepared to brake or swerve if nec‐ essary. End the support by actively steering in non-critical situations. Drive at an appropriate speed if there are pedestrians close to the path of your vehicle. Evasive Steering Assist has the following charac‐ teristics: R Detection of pedestrians, cyclists and vehi‐ cles. R Assistance through power-assisted steering if it detects a swerving maneuver. R Activation by an abrupt steering movement during a swerving maneuver. R Assistance during swerving and straightening of the vehicle. 204 Driving and parking R Reaction from a speed of approximately 12 mph (20 km/h) up to a speed of approx‐ imately 68 mph (110 km/h).

It assists you by displaying detected speed limits and overtaking restrictions in the driver display and in the Head-up Display. The system can issue a warning when you exceed the maximum permissible speed. Vehicles with the Driving Assistance Pack‐ age: in some countries, the system can provide you with further functions and can warn you when you are approaching pedestrian crossings or when you are about to drive past stop signs or red lights unintentionally. The camera also detects and analyzes traffic signs with a restriction indicated by an additional sign (e.g. when wet). Traffic Sign Assist portrays only selected signs in the driver display. Actual traffic signs and speed limits have priority over traffic signs and speed limits shown in the driver display. Also observe the following information: R Select a speed adapted to the traffic, sur‐ roundings and weather conditions R Observe actual traffic signs R Observe applicable traffic rules and regula‐ tions Displays in the driver display Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). 1 Permissible speed 2 Permissible speed when there is a restriction 3 Additional sign with restriction The system can show up to two traffic signs in the driver display simultaneously. The system always prioritizes displaying speed limits. Up to one traffic sign with a maximum permissible speed can be shown in the Head-up Display. If two speed signs are shown in the driver display, for example when speed limits are detected, the value of left-hand speed limit 1 is transmitted to the limiter, cruise control or Active Distance 206 Driving and parking Assist DISTRONIC for adoption and is shown in the Head-up Display. Examples of traffic signs which can be displayed Traffic Sign Assist can detect and display follow‐ ing traffic signs 1: R Speed limits R End of the speed limit R Overtaking restrictions R Play streets R Recommended speeds Traffic Sign Assist can detect following addi‐ tional signs 3 and, if necessary, analyze the relevance of the restrictions using other vehicle sensors: R When wet R Slippery road surfaces R In fog R Temporary restrictions R Exits R Restrictions for vehicle/trailer combinations Traffic Sign Assist also uses data from the digital street map in the navigation system. When you leave or enter a municipality or change roads, on a freeway exit or access road for example, or after you turn at an intersection, the display in the driver display can thus be updated without a traffic sign having been detected. If Traffic Sign Assist cannot determine the cur‐ rently applicable maximum permissible speed (e.g. due to missing signs), the following display appears in the driver display: Traffic Sign Assist is not available in all coun‐ tries. If the vehicle is in a country where Traffic Sign Assist is not supported, this is displayed continuously. % Also observe the information on display mes‐ sages in Traffic Sign Assist (/ page 367). Warning when the maximum permissible speed is exceeded The system can warn you if you unintentionally exceed the maximum permissible speed. To do this, you can specify in the multimedia system by how much the maximum permissible speed can be exceeded before a warning is issued. You can set the warning to visual only (the traffic sign flashes three times in the driver display) or visual and acoustic, including a warning tone. Additional functions of Traffic Sign Assist (country-specific) Warning for no-entry signs: Traffic Sign Assist can warn you if you drive the wrong way down a Driving and parking 207 section of road, for example on freeway access roads or one-way streets. Warning at pedestrian crossings (vehicles with the Driving Assistance Package): if you approach pedestrian crossings, provided that pedestrians are in the danger zone or are moving towards it, Traffic Sign Assist can warn you up to a speed of approximately 44 mph (70 km/h). Warning at stop signs (vehicles with the Driving Assistance Package): Traffic Sign Assist can warn you up to a speed of approx‐ imately 44 mph (70 km/h) if you are about to drive past a stop sign unintentionally. For this to be possible, the signs must be clear, for example if the system detects more than one stop sign, or a stop sign can be confirmed using the digital navigation map. No warning can be issued if sev‐ eral different signs with differing information have been detected. Warning at red lights (vehicles with the Driv‐ ing Assistance Package): Traffic Sign Assist can warn you up to a speed of approximately 44 mph (70 km/h) if you are about to drive through a red light unintentionally. The following conditions must be fulfilled: Several traffic lights have been detected. R All traffic lights detected are red. R At least one of the red traffic lights detected is on the front passenger side beside the vehicle's own lane. R The traffic lights are in the following sequence (from top to bottom): red, yellow, green. R R % If the function is available, you can activate or deactivate the warnings at pedestrian crossings, stop signs and red lights in the Traffic Sign Assist menu under Further Warnings (/ page 208). System limits The system may be impaired or may not function particularly in the following situations: R If visibility is poor, e.g. due to insufficient illu‐ mination of the road, highly variable shade conditions, rain, snow, fog, swirling dust or heavy spray. R R R R R R R If there is glare, e.g. from oncoming traffic, direct sunlight or reflections. If the windshield in the area of the multifunc‐ tion camera is dirty, or if the camera is fog‐ ged up, damaged or covered. If traffic signs are difficult to detect, e.g. because they are dirty, covered, faded, cov‐ ered with ice, damaged, badly positioned, poorly lit or twisted. Active traffic signs with LED displays may not be detected correctly or at all due to techni‐ cal factors, such as transmission frequency. If the information on the navigation system's digital map is incorrect, incomplete or out of date. If signs or the road layout is ambiguous, e.g. traffic signs in roadworks, at exits and ramps, in neighboring lanes or parallel roads. If signs do not conform to the standard.

The system can detect vehicles traveling from speeds of approximately 8 mph (12 km/h) and issue a warning if they move into the monitoring range. Status display in the driver's display ¸ Gray: the system is activated but inopera‐ tive. ¸ Green: the system is activated and opera‐ tional. Driver's display in the Assistance menu If a vehicle is detected at speeds above approx‐ imately 8 mph (12 km/h) and this vehicle enters the monitoring range immediately afterwards, the red warning lamp in the corresponding out‐ side mirror lights up red. In the Assistance menu, the lamp in outside mirror 1 also lights up red, and the lane in which the vehicle is detected is hatched out. If a vehicle is detected in the monitoring range and you switch on the turn signal indicator in the corresponding direction, a double warning tone sounds once and the warning lamp flashes red in the corresponding outside mirror. Red radar waves 2 are displayed next to your vehicle in the Assistance graphic. If the turn signal indicator remains on, the dis‐ play in the outside mirror flashes for all other detected vehicles, but no further warning tone sounds. If you overtake a vehicle quickly, no warning is given. Observe the notes on driving systems and your responsibility; you may otherwise fail to recog‐ nize dangers (/ page 176). & WARNING Risk of accident despite Blind Spot Assist Blind Spot Assist does not react to vehicles approaching and overtaking you at a greatly different speed. Blind Spot Assist cannot warn drivers in this situation. # Always pay careful attention to the traf‐ fic situation and maintain a safe dis‐ tance at the side of the vehicle. 212 Driving and parking Exit warning The exit warning is an additional function of Blind Spot Assist and Active Blind Spot Assist and can warn vehicle occupants attempting to leave a stationary vehicle about approaching vehicles. & WARNING Risk of accident despite exit warning The exit warning neither reacts to stationary objects nor to persons or road users approaching you at a greatly differing speed. The exit warning cannot warn drivers in these situations. # Always pay particular attention to the traffic situation when opening the doors and make sure there is sufficient clear‐ ance. If a vehicle is detected in the monitoring range, the red warning lamp lights up in the corre‐ sponding outside mirror. If a vehicle occupant pulls the door handle on the side of the warning, a warning tone sounds twice and the ambient lighting in the respective door and the warning lamps in the correspond‐ ing outside mirror flash red. % Vehicles with ambient lighting: the Warning Support of the ambient lighting can be activated and deactivated (/ page 130). % The warning assistance can differ depending on the equipment and may vary according to the setting. The exit warning is only available when Blind Spot Assist is activated and up to a maximum of three minutes after the vehicle has been switched off. The exit warning is no longer avail‐ able once the warning lamp in the outside mirror flashes three times. The exit warning is only an aid and not a substi‐ tute for the attention of vehicle occupants. The responsibility for opening and closing the doors and for leaving the vehicle remains with the vehi‐ cle occupants.

Function of Parking Assist PARKTRONIC Parking Assist PARKTRONIC is an electronic parking assistance system which monitors the area surrounding your vehicle and shows you the distance between the vehicle and a detected obstacle visually and audibly. The passive side impact protection also warns you of obstacles to the side. These must be detected beforehand by the sensors in the front or rear bumper while driving by them. If you steer in the direction of a detected obstacle and there is a risk of a lateral collision, a warning is issued. The passive side impact protection can be activated and deactivated via the multimedia system. In order for front or rear obstacles to the side to be displayed, the vehicle must first travel a dis‐ tance of at least half a vehicle length. Once the vehicle has traveled one vehicle length, obsta‐ cles on all sides can be shown. Parking Assist PARKTRONIC is only an aid. It is not a substitute for your attention to the sur‐ roundings. The responsibility for safe maneuver‐ ing and parking remains with you. Make sure that there are no persons, animals or objects in the maneuvering area while maneuvering and parking in/exiting parking spaces. 226 Driving and parking Displays on the central display Vehicles with surround view camera Vehicles with rear view camera As soon as Parking Assist PARKTRONIC is opera‐ tional, the respective areas of the display are shown in blue. 1 Operational, front and rear 2 Operational, all around 3 Operational, all around and obstacle detec‐ ted ting, the system warns you from a distance of 3.3 ft (1 m), in the standard setting only from 1.2 ft (0.4 m).

This feature can help save lives in the event of an accident. eCall in no way replaces assistance provided from dialing 911. Mercedes-Benz eCall only functions in areas where mobile phone coverage is available from the wireless service providers. Insufficient net‐ work coverage from the wireless service provid‐ ers may result in an emergency call not being transmitted. eCall is a standard feature in your MercedesBenz vehicle. In order to function as intended, the system relies on the transmission of data detailed in the Transmitted Data section that fol‐ lows. To disable eCall, a customer must visit an authorized Mercedes-Benz Service department to deactivate the vehicle’s communication mod‐ ule. Deactivation of this module prevents the activa‐ tion of any and all Mercedes me connect serv‐ ices. After the deactivation of eCall, automatic emergency call and manual emergency call will not be available. The vehicle must be switched on before an auto‐ matic emergency call can be made. % eCall is activated at the factory. % eCall can be deactivated by an authorized Mercedes-Benz dealer. Please note that in the event ownership of the vehicle is trans‐ ferred to another owner in its deactivated state, eCall will remain deactivated unless the new owner visits an authorized Mercedes-Benz dealership to reactivate the system. Overview of the Mercedes-Benz emergency call system eCall can help to reduce the time between an accident and the arrival of emergency services at the site of the accident. It helps locate an accident site in places that are difficult to access. However, even if a vehicle is equipped with eCall, this does not mean the system is ON. As such, eCall does not replace dialing 911 in the event of an accident. An emergency call can be made automatically or manually. Only make emergency calls if you or others are in need of rescue. Do not make an emergency call in the event of a breakdown or a similar sit‐ uation. Triggering an automatic Mercedes-Benz emergency call Requirements: R The vehicle is switched on. R The starter battery is sufficiently charged. The Mercedes-Benz emergency call system trig‐ gers an emergency call automatically in the fol‐ lowing cases: R After activation of the restraint systems such as airbags or Emergency Tensioning Devices after an accident 278 MBUX multimedia system R After an automatically initiated emergency stop by Active Emergency Stop Assist The emergency call has been made: R A voice connection is made to the MercedesBenz emergency call center. R A message with accident data is transmitted to the Mercedes-Benz emergency call center. The Mercedes-Benz emergency call center can transmit the vehicle position data to one of the emergency call centers. The SOS button in the overhead control panel flashes until the emergency call is finished. It is not possible to immediately end an auto‐ matic emergency call. If no connection can be made to the emergency services either, a corresponding message appears in the media display. # Dial the local emergency number on your mobile phone. If an emergency call has been initiated: R Remain in the vehicle if the road and traffic conditions permit you to do so until a voice R R connection is established with the emer‐ gency call center operator. Based on the call, the operator decides whether it is necessary to call rescue teams and/or the police to the accident site.

Notes on regularly inspecting wheels and tires & WARNING Risk of injury through dam‐ aged tires Damaged tires can cause tire pressure loss. # Check the tires regularly for signs of damage and replace any damaged tires immediately. & WARNING Risk of hydroplaning due to insufficient tire tread Insufficient tire tread will result in reduced tire grip. In heavy rain or slush the risk of hydroplaning is increased, in particular where speed is not adapted to suit the conditions. # Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. R R R Visually inspect wheels and tires for damage. Check the valve caps. Visual check of the tire tread depth and the tire contact surface across the entire width. The minimum tread depth for summer tires is â in (3 mm) and for winter tires ã in (4 mm). Minimum tread depth for: R Summer tires: â in (3 mm) R M+S tires: ãin (4 mm) # For safety reasons, replace the tires before the legally-prescribed limit for the minimum tread depth is reached. Carry out the following checks on all wheels reg‐ ularly, at least once a month or as required, for example, prior to a long journey or driving offroad: R Check the tire pressure (/ page 323). Six marks 1 show where the bar indicators (arrow) are integrated into the tire tread. They are visible once a tire tread depth of approx‐ imately á in (1.6 mm) has been reached. Wheels and tires 323 Notes on snow chains & WARNING Risk of accident due to incor‐ rect mounting of snow chains If you have mounted snow chains to the front wheels, the snow chains may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires. # Never mount snow chains on the front wheels. # Only mount snow chains on the rear wheels in pairs. * NOTE Damage to components of the vehicle body or chassis due to mounted snow chains If you mount snow chains to the front wheels of 4MATIC vehicles, you may damage compo‐ nents of the vehicle body or chassis. # Only mount snow chains to the rear wheels of 4MATIC vehicles. Observe the following notes when using snow chains: R Snow chains are only permissible for certain wheel/tire combinations. You can obtain information about this from an authorized Mercedes-Benz Center. R For safety reasons, only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz, or snow chains with the same quality standard. R If snow chains are installed, the maximum permissible speed is 30 mph (50 km/h). R Vehicles with Active Parking Assist: Do not use Active Parking Assist when snow chains are installed. % You can deactivate ESP® to pull away (/ page 180). This allows the wheels to spin, achieving an increased driving force. Tire pressure Notes on tire pressure & WARNING Risk of accident due to insuf‐ ficient or excessive tire pressure Underinflated or overinflated tires pose in particular the following risks: R The tires can burst. R The tires can wear excessively and/or unevenly. R The driving characteristics as well as the steering and braking characteristics may be greatly impaired. # R R R Comply with the recommended tire pressures and check the tire pressure of all tires, including the spare wheel, regularly: Monthly When the load changes Before embarking on a longer journey 324 Wheels and tires R # If operating conditions change, e.g. offroad driving R Adjust the tire pressure, if necessary. R Tire pressure which is too high or too low can: R Shorten the service life of the tires. R Cause increased tire damage. R Adversely affect driving characteristics and thus driving safety, e.g. due to hydroplaning. & WARNING Risk of accident due to too low a tire pressure Tires with pressure that is too low can over‐ heat and burst as a consequence. In addition, they also suffer from irregular wear, which can significantly impair the brak‐ ing properties and the handling characteris‐ tics. # Avoid excessively low tire pressure. Tire pressure which is too low can cause: R Tire malfunctions as a result of overheating R Impaired handling characteristics Irregular wear Increased fuel consumption & WARNING Risk of accident due to too high a tire pressure Tires with excessively high pressure can burst. In addition, they also suffer from irregular wear, which can significantly impair the brak‐ ing properties and the handling characteris‐ tics. # Avoid excessively high tire pressures. Tire pressure which is too high can cause: R Increased braking distance R Impaired handling characteristics R Irregular wear R Impaired driving comfort R Susceptibility to damage & WARNING Risk of accident due to repea‐ ted pressure drop in the tires The wheels, valves or tires could be dam‐ aged. Too low a tire pressure can lead to the tires bursting. # Examine the tires for foreign objects. # Check whether the tire has a puncture or the valve has a leak. # If you are unable to rectify the damage, contact a qualified specialist workshop. You can find information on tire pressure for the vehicle's factory-installed tires on the following labels: R Tire and Loading Information placard on the B‑pillar of your vehicle (/ page 330). R Tire pressure table on the inside of the fuel filler flap (/ page 325). Observe the maximum tire pressure (/ page 336). Wheels and tires 325 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. Only correct tire pressure when the tires are cold. Conditions for cold tires: R The vehicle has been parked with the tires out of direct sunlight for at least three hours. R The vehicle has traveled less than 1 mile (1.6 km). The vehicle's tires heat up when driving. As the temperature of the tires increases, so too does the tire pressure. Vehicles with a tire pressure monitoring sys‐ tem: You can also see the tire pressure in the driver's display. The tire pressure recommended for increased load/speed in the tire pressure table can affect the ride comfort. & WARNING Risk of accident due to unsuitable accessories on tire valves If you mount unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. # Only screw standard valve caps or valve caps specifically approved by Mercedes-Benz for your vehicle onto the tire valve. Tire pressure table The tire pressure table is on the inside of the fuel filler flap. % The data shown in the images is example data. If one or more tire sizes precede a tire pressure, the following tire pressure information is only valid for those tire sizes and their respective load condition. The load conditions "partially laden" and "fully laden" are defined in the table for different num‐ bers of passengers and amounts of luggage. The actual number of seats may differ from this. 326 Wheels and tires Checking the tire pressure manually R Read the tire pressure recommended for the current operating conditions from the Tire and Loading Information placard or the tire pressure table. Observe the notes on tire pressure. # Remove the valve cap of the tire to be checked. # Press the tire pressure gauge securely onto the valve. # Read the tire pressure. # If the tire pressure is lower than the recom‐ mended value, increase the tire pressure to the recommended value. # If the tire pressure is higher than the recom‐ mended value, release air. To do so, press down the metal pin in the valve, e.g. using the tip of a pen, for example. Then check the tire pressure again using the tire pressure gauge. # Screw the valve cap onto the valve. Further related subjects: R Notes on tire pressure (/ page 323) R # Some tire pressure tables only show the rim diameter instead of the complete tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire side wall (/ page 337). R Tire and Loading Information placard (/ page 330) R Maximum tire pressure (/ page 336) Tire pressure table (/ page 325) Tire and Loading Information placard (/ page 330) Tire pressure monitoring system Function of the tire pressure monitoring sys‐ tem & DANGER Risk of accident due to incor‐ rect tire pressure Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommen‐ ded by the vehicle manufacturer on the vehi‐ cle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should deter‐ mine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor‐ ing system (TPMS) that illuminates a low tire Wheels and tires 327 pressure telltale when one or more of your tires is significantly under-inflated. Accord‐ ingly, when the low tire pressure telltale illu‐ minates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a signifi‐ cantly under-inflated 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 han‐ dling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsi‐ bility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pres‐ sure 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 sys‐ tem detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illumina‐ ted, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of rea‐ sons, including the installation of replace‐ ment or alternate tires or wheels on the vehi‐ cle that prevent the TPMS from functioning properly. The system checks the tire pressure and the tire temperature of the tires installed on the vehicle by means of a tire pressure sensor. The tire pressure and the tire temperature appear on the driver display (/ page 327). If there is a substantial pressure loss or if the tire temperature is excessive, you will be warned with display messages (/ page 417) or the h warning lamp on the driver display (/ page 439). The tire pressure monitoring system is only an aid. It is the driver's responsibility to set the tire pressure to the recommended cold tire pressure suitable for the operating situation. In most cases, the tire pressure monitoring sys‐ tem will automatically update the new reference values after you have changed the tire pressure. You can, however, also update the reference val‐ ues by restarting the tire pressure monitoring system manually (/ page 328). System limits The system may be impaired or may not function particularly in the following situations: R Incorrect reference values were taught in R Sudden pressure loss caused by a foreign object penetrating the tire, for example R There is a malfunction caused by another radio signal source Checking the tire pressure with the tire pres‐ sure monitoring system Requirements: R The vehicle is switched on. 328 Wheels and tires Driver's display: 4 © 5 Service # Select Tire Pressure and confirm with a.

Overloaded tires can also impair the steering and handling characteris‐ tics and lead to brake failure. # Observe the load rating of the tires. # The load rating must be at least half the permissible axle load of the vehicle. # Never overload the tires by exceeding the maximum load. The Tire and Loading Information placard is on the B-pillar on the driver's side of the vehicle. 1 Tire and Loading Information placard % The data shown in the illustration is example data. The Tire and Loading Information placard shows the following information: R Maximum number of seats 2 according to the maximum number of people permitted to travel in the vehicle. Wheels and tires 331 R R Maximum permissible load 3 comprises the gross weight of all vehicle occupants, load and luggage. Recommended tire pressure 1 for cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed.

Further related subjects: Determining the maximum permissible load (/ page 331) R Notes on tire pressure (/ page 323). R Steps for Determining Correct Load Limit The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575, pur‐ suant to the "National Traffic and Motor Vehicle Safety Act of 1966". # (1): Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's placard. # (2): Determine the combined weight of the driver and passengers that will be riding in your vehicle. # (3): Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs. # (4): The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1,400 lbs. and there will be five 150 lb pas‐ sengers in your vehicle, the amount of availa‐ ble cargo and luggage load capacity is 650 lbs. (1,400 - 750 (5 x 150) = 650 lbs.) # (5): Determine the combined weight of lug‐ gage and cargo being loaded on the vehicle. That weight may not safely exceed the availa‐ # ble cargo and luggage load capacity calcula‐ ted in Step 4. (6): If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to deter‐ mine how this reduces the available cargo and luggage load capacity of your vehicle. % Not all vehicles are permitted to tow a trailer. Towing a trailer is only permitted if a trailer-hitch is installed. Please consult an authorized Mercedes-Benz dealer if you have any questions about towing a trailer with your vehicle. Even if you have calculated the total load care‐ fully, you should still make sure that the maxi‐ mum permissible gross weight and the maxi‐ mum gross axle weight rating of your vehicle are not exceeded. Details can be found on the vehi‐ cle identification plate. 332 Wheels and tires Have your loaded vehicle – including driver, occupants and load – weighed on a vehicle weighbridge. The measured values may not exceed the maximum permissible values stated on the vehicle identification plate.

Tire Quality Grading In accordance with the US Department of Trans‐ portation's "Uniform Tire Quality Grading Stand‐ ards", tire manufacturers are required to grade their tires on the basis of the following three per‐ formance factors: 1 Uniform Tire Quality Grading Standards 2 DOT (Department of Transportation), (TIN) Tire Identification Number 3 Maximum tire load (/ page 336) 4 Maximum tire pressure (/ page 336) 1 Tread wear grade 2 Traction grade 3 Temperature grade % The data shown in the illustration is example data. % The classification is not legally stipulated for Canada, but it is generally stated. Tread wear grade The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified gov‐ ernment test course. For example, a tire graded 150 would wear one and one-half (1\1/2\) Wheels and tires 335 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. 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 meas‐ ured under controlled conditions on specified government test surfaces of asphalt and con‐ crete. A tire marked C may have poor traction performance. Traction grade Temperature grade & DANGER Risk of accident due to inade‐ quate traction The traction grade assigned to this tire is based on straight-ahead braking traction tests. # Always adapt your driving style and drive at a speed to suit the prevailing traffic and weather conditions. * NOTE Damage to the drivetrain from wheelspin # Avoid wheelspin. & WARNING Risk of accident from tire overheating and tire failure Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possi‐ ble tire failure. # Observe the recommended tire pres‐ sure. # Regularly check the pressure of all the tires. # Adjust the tire pressure, if necessary. 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. Sus‐ tained 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 Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. DOT, Tire Identification Number (TIN) US tire regulations stipulate that every tire man‐ ufacturer or retreader must imprint a TIN in or on the side wall of each tire produced. 336 Wheels and tires R R R % The data shown in the image is example data.

For wheels, pay attention to the following: R Designation R Type For tires, pay attention to the following: R Designation R Manufacturer R Type & WARNING Risk of injury through exceed‐ ing the specified tire load-bearing capa‐ city or the permissible speed rating Exceeding the specified tire load rating or the permissible speed rating may lead to tire damage and to the tires bursting. # Therefore, only use tire types and sizes approved for your vehicle model. # Observe the tire load rating and speed rating required for your vehicle. * NOTE Vehicle and tire damage through tire types and sizes that have not been approved For safety reasons, only use tires, wheels and accessories which have been specially approved by Mercedes-Benz for your vehicle. These tires are specially adapted to the active safety systems, such as ABS, ESP® and 4MATIC, and marked as follows: R MO = Mercedes-Benz Original R R MOE = Mercedes-Benz Original Extended (run-flat tire only for certain wheels) MO1 = Mercedes-Benz Original (only cer‐ tain AMG tires) Otherwise, certain properties, such as han‐ dling characteristics, vehicle noise emis‐ sions, consumption, etc. could be adversely affected. Furthermore, other tire sizes could result in the tires rubbing against the body and axle components when loaded. This could result in damage to the tire or the vehi‐ cle. Only use tires, wheels and accessories that have been checked and recommended by Mercedes-Benz. * NOTE Risk to driving safety from retrea‐ ded tires Retreaded tires are neither tested nor recom‐ mended by Mercedes-Benz, since previous damage cannot always be detected on retreaded tires. Wheels and tires 343 For this reason driving safety cannot be guar‐ anteed. # Do not use used tires if you have no information about their previous usage. * NOTE Possible wheel and tire damage when driving over obstacles Large wheels have a smaller section width. As the section width decreases, the risk of wheels and tires being damaged when driv‐ ing over obstacles increases. # Avoid obstacles or drive especially care‐ fully. # Reduce your speed when driving over curbs, speed bumps, manhole covers and potholes. # Avoid particularly high curbs. * NOTE Possible wheel and tire damage when parking on curbs or in potholes Parking on curbs or in potholes may damage the wheels and tires. # # If possible, park only on flat surfaces. Avoid curbs and potholes when parking. * NOTE Damage to electronic component parts from the use of tire-mounting tools Vehicles with a tire pressure monitoring system: Electronic component parts are located in the wheel. Tire-mounting tools should not be used in the area of the valve. This could otherwise damage the electronic component parts. # Have the tires changed at a qualified specialist workshop only. * NOTE Damage to summer tires at low ambient temperatures At low ambient temperatures, tears could form when driving with summer tires, caus‐ ing permanent damage to the tires. # At temperatures below 45 °F (7 °C) use i M+S tires. Accessory parts which are not approved for your vehicle by Mercedes-Benz, or which are not used correctly, can impair the operating safety. Before purchasing and using non-approved accessories, visit a qualified specialist workshop and inquire about: R Suitability R Legal stipulations R Factory recommendations & WARNING Risk of accident with high performance tires The special tire tread in combination with the optimized tire compound means that the risk of skidding and hydroplaning on wet roads is increased. In addition, the tire grip is greatly reduced at a low outside temperature and tire running temperature. # Switch on the ESP® and adapt your driving style accordingly. 344 Wheels and tires # # Use i M+S tires at outside temper‐ atures of less than 50 °F (10 °C). Only use the tires for their intended pur‐ pose. Observe the following when selecting, installing and replacing tires: R Furthermore, the use of certain tire types in certain regions and areas of operation can be highly beneficial. R Only use tires and wheels of the same type (summer tires, winter tires, MOExtended tires) and the same make. R Only install wheels of the same size on one axle (left and right). It is only permissible to install a different wheel size in the event of a flat tire in order to drive to the specialist workshop. R Vehicles with a tire pressure monitoring system: All installed wheels must be equip‐ ped with functioning sensors for the tire pressure monitoring system. R R R R R R At temperatures below 45 °F (7 °C) use win‐ ter tires or all-season tires marked i M+S for all wheels. Winter tires provide the best possible grip in wintry road conditions. For M+S tires, only use tires with the same tread. Observe the maximum permissible speed for the M+S tires installed. If the tire's maximum speed is below that of the vehicle, this must be indicated by an appropriate label in the driver's field of vision. Break in new tires at moderate speeds for the first 60 miles (100 km). Replace the tires after six years at the latest, regardless of wear. When replacing with tires that do not fea‐ ture run-flat characteristics: vehicles with MOExtended tires are not equipped with a TIREFIT kit at the factory. Equip the vehicle with a TIREFIT kit after replacing with tires that do not feature run-flat characteristics, e.g. winter tires.
