Our objectives are to use the natural resources which form the basis of our existence on this planet sparingly and in a manner which takes the requirements of both nature and humanity into consideration. You too can help to protect the environment by operating your vehicle in an environmentally-responsible manner. Fuel consumption and the rate of engine, transmission, brake and tyre wear depend on the following factors: Roperating conditions of your vehicle personal driving style You can influence both factors. Therefore, please bear the following in mind: Operating conditions: Ryour short trips, as these increase fuel consumption. Robserve the correct tyre pressure. Rdo not carry any unnecessary weight in the vehicle. Rremove the roof rack once you no longer need it. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Rall maintenance work should be carried out at a qualified specialist workshop. Personal driving style: Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. off the engine in stationary traffic. Rmonitor the vehicle's fuel consumption. Rswitch Returning an end-of-life vehicle EU countries only: Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-responsible manner in accordance with the European Union (EU) End of Life Vehicles Directive. There is a network of return points and disassembly plants available. You can return your vehicle to these plants free of charge. This makes a valuable contribution to the recycling process and the conservation of resources. For further information on recycling old vehicles, recovery and the terms of the policy, visit the Mercedes-Benz homepage. Ravoid Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine when the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. Ravoid frequent, sudden acceleration and braking. Genuine Mercedes-Benz parts H Environmental note Daimler AG also supplies reconditioned assemblies and parts which are of the same quality as new parts. For these, the same warranty applies as for new parts. ! Airbags and seat belt tensioners, as well as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars sills Rseats Rdashboard Rinstrument cluster Rcentre console Rdoor Z 23 24 Introduction Do not install accessories such as audio systems in these areas. Do not carry out repairs or welding. You could impair the operating efficiency of the restraint systems. Have accessories retrofitted at a qualified specialist workshop. You could jeopardise the operating safety of your vehicle if you use parts, tyres and wheels as well as accessories relevant to safety which have not been approved by Mercedes. This could lead to malfunctions in safety-relevant systems, e.g. the brake system. Use only genuine Mercedes-Benz parts or parts of equal quality. Only use tyres, wheels and accessories that have been specifically approved for your vehicle. Mercedes-Benz tests genuine parts and conversion parts and accessories that have been specifically approved for your vehicle for their reliability, safety and suitability. Despite ongoing market research, Mercedes-Benz is unable to assess other parts. Mercedes-Benz therefore accepts no responsibility for the use of such parts in Mercedes-Benz vehicles, even if they have been officially approved or independently approved by a testing centre. In Germany, certain parts are only officially approved for installation or modification if they comply with legal requirements. This also applies to some other countries. All genuine Mercedes-Benz parts meet the approval requirements. The use of non-approved parts may invalidate the vehicle's general operating permit. This is the case: Rif they cause a change of the vehicle type from that for which the vehicle's general operating permit was granted Rif other road users could be endangered Rif the emission or noise levels are adversely affected Always specify the vehicle identification number (VIN) when ordering genuine MercedesBenz parts (Y page 398). Owner's Manual Vehicle equipment This Owner's Manual describes all models and all standard and optional equipment available for your vehicle at the time of publication of the Owner's Manual. Country-specific differences are possible. Note that your vehicle may not be fitted with all features described. This is also the case for systems and functions relevant to safety. Therefore, the equipment on your vehicle may differ from that in the descriptions and illustrations. The original purchase contract documentation for your vehicle contains a list of all of the systems in your vehicle. Should you have any questions concerning equipment and operation, please consult a Mercedes-Benz Service Centre. The Owner's Manual and Service Booklet are important documents and should kept in the vehicle. Operating safety Important safety notes G WARNING If you do not have the prescribed service/ maintenance work or necessary repairs carried out, this could result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/maintenance work as well as necessary repairs carried out at a qualified specialist workshop. G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. Introduction G WARNING Flammable material such as leaves, grass or twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire. When driving off road or on unpaved roads, check the vehicle's underside regularly. In particular, remove parts of plants or other flammable materials which have become trapped. In the case of damage, contact a qualified specialist workshop. G WARNING Modifications to electronic components, their software as well as wiring could effect their function and/or the operation of other networked components. This could in particular also be the case for systems relevant to safety. They might not function properly any more and/or jeopardise the operational safety of the vehicle. There is an increased risk of an accident and injury. Do not attempt to modify the wiring as well as electronic components or their software. Always have work on electrical and electronic components carried out at a qualified specialist workshop. If the underbody panelling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody panelling.

Occupant safety Introduction to the restraint system The restraint system reduces the risk of vehicle occupants coming into contact with parts of the vehicle's interior in the event of an accident. Furthermore, the restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. The restraint system includes: RSeat belt system RAirbags RChild Panic alarm restraint system seat securing system The various components of the restraint system work complementary to one another. It can only provide maximum protection if all vehicle occupants: RChild Rhave To activate: press ! button : for approximately one second. An alarm sounds and the exterior lighting flashes. X To deactivate: press ! button : again. or X Insert the key into the ignition lock. or X Press the KEYLESS-GO Start/Stop button. The KEYLESS-GO key must be in the vehicle. X i The panic alarm function is only available in certain countries. their seat belt correctly fastened (Y page 45) Rhave correctly adjusted their seat and head restraint (Y page 105). As the driver, you must also ensure that the steering wheel is correctly adjusted. Observe the information relating to the correct driver's seat position (Y page 104). Additionally, you must ensure that an airbag can deploy freely (Y page 48). An airbag is supplementary to a correctly fastened seatbelt and, as an additional safety device, provides greater protection for vehicle occupants in an accident situation. If the protection provided by the seat belt is sufficient, the airbags do not deploy. Furthermore, in the event of an accident, only airbags which provide greater protection in the given accident situation deploy. However, seat belts and airbags generally do not protect against objects penetrating the vehicle from the outside. Information on how the restraint system operates can be found in "Deployment of the seat belt tensioner and airbags" (Y page 51). See "Children in the vehicle" for further information on children travelling in the vehicle as well as on child restraint systems (Y page 55). Important safety notes G WARNING If the restraint system is modified, it may no longer work as intended. The restraint system may then not perform its intended protective function by failing in an accident or triggering unexpectedly, for example. There is an increased risk of injury, possibly even fatal. Never modify parts of the restraint system. Do not attempt to modify the wiring as well as electronic components or their software. G WARNING If the restraint system is malfunctioning, restraint system components may be triggered unintentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. This can effect belt tensioners or airbags, for example. There is an increased risk of serious or even fatal injuries. Have the restraint system checked and repaired immediately at a qualified specialist workshop. PASSENGER AIR BAG OFF indicator lamp If it is necessary to modify an airbag system to accommodate a person with disabilities, contact an authorised Mercedes-Benz Centre. Restraint system warning lamp The operation of the restraint system is checked when the ignition is switched on and at regular intervals while the engine is running. This allows malfunctions to be quickly identified. The 6 restraint system warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. The various components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up when the ignition is switched on Rdoes not go out after a few seconds while the engine is running Rlights up again while the engine is running PASSENGER AIR BAG OFF indicator lamp : is part of the automatic child seat recognition on the front-passenger seat. A permanently lit PASSENGER AIR BAG OFF indicator lamp informs you that the frontpassenger front airbag is disabled. Depending on the person in the frontpassenger seat, the front-passenger front airbag must either be disabled or enabled. You must make sure of this both before and during a journey. RChildren in a child restraint system: whether the front-passenger front airbag is enabled or disabled depends on the installed child restraint system, and the age and size of the child. Therefore, always observe the information on "Children in the vehicle" (Y page 55). There you will also find instructions on backwards and forwardsZ 43 Safety Occupant safety Safety 44 Occupant safety facing child restraint systems on the frontpassenger seat. RAll other persons: the PASSENGER AIR BAG OFF indicator lamp must be off. Be sure to observe the notes on "Seat belts" (Y page 44) and "Airbags" (Y page 48). There you can also find information on the correct seat position. Observe the information on automatic child seat recognition in the front-passenger seat (Y page 59). Seat belts Introduction A correctly fastened seat belt is the most effective means of limiting the movement of a vehicle occupant during a collision or in the event that the vehicle overturns. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior or being ejected from it. Furthermore, the seat belt helps to keep the vehicle occupant in the best position in relation to a deployed airbag. The seat belt system consists of: Rseat belts tensioners for the front seat belts and the outer seat belts in the rear Rseat belt force limiters for the front seat belts and the outer seat belts in the rear If the seat belt is pulled quickly or suddenly from the belt sash guide, the inertia reel locks. The belt strap cannot be pulled out further. In an impact, the belt tensioner tightens the belt to pull it close to the body. It does not pull the vehicle occupant back in the direction of the seat backrest, however. In addition, the belt tensioner cannot compensate for the seat position being incorrect or for an incorrectly worn seat belt. If the seat belt is also fitted with a belt force limiter and this is triggered, the force exerted Rbelt by the seat belt on the vehicle occupant is reduced. The belt force limiters on the front seats are synchronised with the front airbags, which take on a part of the deceleration force. This helps to reduce the forces to which vehicle occupants are subjected during an accident. ! If the co-driver's seat is not occupied, do not engage the seat belt tongue in the buckle on the co-driver's seat. Otherwise, the belt tensioner could be triggered in the event of an accident and would have to be replaced. Important safety notes G WARNING The seat belt cannot perform its intended protective function if it is not fastened correctly. Also, an improperly fastened seat belt can cause additional injuries in the event of an accident, sudden braking or abrupt changes of direction. There is an increased risk of injury, possibly even fatal. Always make sure that all vehicle occupants are wearing their seat belt and positioned correctly. G WARNING The seat belt does not offer the intended level of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdomen or neck injuries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always ensure that the backrest is in an almost vertical position and that the shoulder section of your seatbelt is routed across the centre of your shoulder. G WARNING Persons under 1.50 m tall cannot wear the seat belts correctly without a suitable, addi- Occupant safety If you are travelling with a child younger than 12 years of age and under 1.50 m tall in the vehicle: Ralways secure the child in a child restraint system suitable for this Mercedes-Benz vehicle. The child restraint system must be appropriate to the age, weight and size of the child. Rensure that you observe the instructions and safety notes on "Children in the vehicle" in these Operating Instructions (Y page 55) in addition to the child restraint system manufacturer's instructions G WARNING Seat belts cannot protect as intended, if: Rthey are damaged, have been modified, are extremely dirty, bleached or dyed seat belt buckle is damaged or extremely dirty Rmodifications have been made to the belt tensioners, belt anchorages or inertia reels Damage caused to safety belts in an accident may not be visible, e.g. by splinters of glass. Modified or damaged seat belts can tear or fail, for example in the event of an accident. Modified seat belt tensioners may be deployed unintentionally or fail to be deployed when required. There is an increased risk of injury, possibly even fatal. Never modify safety belts, seat belt tensioners, seat belt anchorages and inertia reels. Ensure that seat belts are not damaged or worn and are clean. After an accident, have Rthe the seat belts checked immediately at a qualified specialist workshop. Mercedes-Benz recommends that you only use seat belts which have been approved specifically for your vehicle by MercedesBenz. Correct seat belt use Observe the safety notes on the seat belt (Y page 44). All vehicle occupants must be wearing the seat belt correctly before beginning the journey. Also make sure that all vehicle occupants are always wearing the seat belt correctly while the vehicle is in motion. When fastening the seat belt, always make sure that: Rthe seat belt tongue is only inserted to the belt buckle belonging to that seat. Rthe seat belt is tight across your body. Avoid wearing bulky clothing, e.g. a winter coat. Rthe seat belt is not twisted. Only then can forces which occur be distributed across the surface of the seat belt. Rthe shoulder section of the belt is always routed across the centre of your shoulder. The shoulder section of the seat belt should not touch your neck nor be routed under your arm. If possible, adjust the seat belt to the appropriate height. Rthe lap belt passes across your lap as tightly and as low down as possible. The lap must always be routed across your hip joints and never across your abdomen. This applies particularly to pregnant women. If necessary, press the lap belt down into your hip joints and pull tight with the shoulder section of the belt. Rthe seat belt is not routed across sharp, pointed or fragile objects. If you have such items located on or in your clothing, e.g. pens, keys or spectacles, store these in a suitable place. Z Safety tional restraint system. The seat belt cannot perform its intended protective function if it is not fastened correctly. Also, an improperly fastened seat belt can cause additional injuries in the event of an accident, sudden braking or abrupt changes of direction. There is an increased risk of injury, possibly even fatal. Secure persons less than 1.50 m tall in a suitable restraint system. 45 Occupant safety 46 Safety Ronly one person is using a seat belt. Infants and children must never travel sitting on the lap of a vehicle occupant. In the event of an accident, they could be crushed between the vehicle occupant and seat belt. Robjects are never secured with a seat belt if the seat belt is also being used by one of the vehicle's occupants. Seat belts are only intended to secure and restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects, luggage or loads (Y page 300). automatically, see "Belt adjustment" (Y page 47). X If necessary, pull upwards on the shoulder section of the seat belt to tighten the belt across your body. Fastening and adjusting the seat belts Observe the safety notes on the seat belt (Y page 44) and the notes on correct use of seat belts (Y page 45). If the centre rear seat belt is being used, also observe the information about the seat belt for the centre rear seat (Y page 46). The shoulder section of the seat belt must always be routed across the centre of the shoulder. Adjust the belt sash guide if necessary. To raise: slide the belt guide upwards.

Seat belt adjustment The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. This function adjusts the driver's and frontpassenger seat belt to the upper body of the occupants. The belt strap is tightened slightly when: Rthe seat belt tongue is engaged in the belt buckle and Rthe ignition is switched on The seat-belt adjustment will apply a certain tightening force if any slack is detected between the vehicle occupant and the seat belt. Do not hold on to the seat belt tightly while it is adjusting. You can switch the seat-belt adjustment on and off in the on-board computer (Y page 257). The seat belt on the right rear seat, when viewed in the direction of travel, is not fastened. (Example: CLS Coupé) The status indicator for the rear-compartment seat belts is only available for certain countries. For approximately 30 seconds, the rear seat belt status indicator informs you which rear seat belt is not fastened. The rear seat belt status indicator appears if: Ryou drive off and reach a speed of approximately 10 km/h. Rthe rear passengers fasten or unfasten their seat belts while the vehicle is in motion. Rsomeone gets in or out of the vehicle and you pull away again. You can also cancel the rear seat belt status indicator immediately (Y page 261). Z Safety will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Damaged seat belts can no longer fulfil their protective function and must be replaced. Visit a qualified specialist workshop. 47 48 Occupant safety Airbags Safety Introduction The AIRBAG symbol indicates the installation location of an airbag. The airbag is supplementary to a correctly fastened seatbelt. It does not replace a seatbelt. The airbag serves to provide additional protection in an accident situation. Not all airbags are deployed in an accident. The various airbag systems work independently of one another (Y page 51). However, no system available today can completely eliminate injuries and fatalities. Due to the speed of airbag deployment, it is also not possible to entirely rule out the risk of injuries caused by the driver's airbag deploying. Important safety notes G WARNING If you deviate from the correct seat position, the airbag cannot perform its intended protective function and can even cause additional injuries when deployed. There is an increased risk of serious or even fatal injuries. In order to avoid such risks, always ensure that all vehicle occupants: Rfasten their seatbelts correctly, including pregnant women Rare seated correctly and maintain the furthest possible distance from the airbags Robserve the following notes Always ensure that there are no objects located between the airbag and the vehicle occupant. RAdjust the seats properly before beginning your journey. Always make sure that the seat is in an almost upright position. The centre of the head restraint must support the head at about eye level. RMove the driver's and front-passenger seats as far back as possible. The driver's seat position must allow the vehicle to be driven safely. ROnly hold the steering wheel on the outside. This allows the airbag to be fully deployed. RAlways lean against the backrest while driving. Do not lean forwards or lean against the door or side window. You may otherwise be in the deployment area of the airbags. RAlways keep your feet in the footwell in front of the seat. Do not put your feet on the dashboard, for example. Your feet may otherwise be in the deployment area of the airbag. RFor this reason, always secure persons less than 1.50 m tall in suitable restraint systems. Up to this height, the seat belt cannot be worn correctly. If a child is travelling in your vehicle, also observe the following notes: RAlways secure children under 12 years of age and less than 1.50 m tall in suitable child restraint systems. RChild restraint systems should be fitted to the rear seats. ROnly secure a child to the front-passenger seat when the front-passenger front airbag is disabled, and only then in a rearwardfacing child restraint system. If the PASSENGER AIR BAG OFF indicator lamp is permanently lit, the front-passenger front airbag is disabled (Y page 43). RAlways observe the instructions and safety notes on "Children in the vehicle" (Y page 55) and on the "Child restraint system on the front-passenger seat" (Y page 61) in addition to the child restraint system manufacturer's installation instructions. Occupant safety are no people, animals or objects between the vehicle occupants and an airbag. Rthere are no objects between the seat, door and B-pillar. Rno hard objects, e.g. coat hangers, hang on the grab handles or coat hooks. Rno accessories, such as cup holders, are attached to the vehicle within the deployment area of an airbag, e.g. to doors, side windows, rear side trim or side walls. Rno heavy, sharp-edged or fragile objects are in the pockets of your clothing. Store such objects in a suitable place. Front airbags Safety Objects in the vehicle interior may prevent the airbag from functioning correctly. Before starting your journey and to avoid risks resulting from the speed of the airbag as it deploys, make sure that: Rthere G WARNING If you modify an airbag cover or affix objects such as stickers to it, the airbag can no longer function correctly. There is an increased risk of injury. Never modify an airbag cover or affix objects to it. G WARNING Sensors to control the airbags are located in the doors. Modifications or work not performed correctly to the doors or door panelling, as well as damaged doors, can lead to the function of the sensors being impaired. The airbags might therefore not function properly any more. Consequently, the airbags cannot protect vehicle occupants as they are designed to do. This poses an increased risk of injury. Never modify the doors or parts of the doors. Always have work on the doors or door panelling carried out at a qualified specialist workshop. 49 Driver's airbag : deploys in front of the steering wheel; front-passenger front airbag ; deploys in front of and above the glove compartment. When deployed, the front airbags offer additional head and thorax protection for the occupants in the front seats. The permanently lit PASSENGER AIR BAG OFF indicator lamp shows you that the frontpassenger front airbag is deactivated (Y page 43). Driver's kneebag Driver's kneebag : deploys under the steering column. The driver's kneebag is triggered together with the front airbag. The driver's kneebag offers additional thigh, knee and lower leg protection for the occupant in the driver's seat. i The driver's kneebag is only available in certain countries. Z 50 Occupant safety Safety Sidebags G WARNING Unsuitable seat covers may obstruct or even prevent deployment of the airbags integrated into the seats. The airbags may then fail to protect the vehicle occupants as intended. Operation of the automatic child seat recognition may also be impaired. There is an increased risk of injury, possibly even fatal. Use only seat covers which have been specifically approved for the respective seat by Mercedes-Benz. Operation of the automatic child seat recognition may also be impaired. There is an increased risk of injury, possibly even fatal.

The pelvisbag is deployed on the side of the impact. i Pelvisbags are only available in certain countries. Windowbags Rhead Rneck Rarms In the event of a side impact, the sidebag is deployed on the side on which the impact occurs. Pelvisbags G WARNING Unsuitable seat covers may obstruct or even prevent deployment of the airbags integrated into the seats. The airbags may then fail to protect the vehicle occupants as intended. Example: Coupé Windowbags : are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. When deployed, the windowbag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the windowbag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a windowbag may be deployed in other accident situations (Y page 51). Deployment of belt tensioners and airbags Important safety notes G WARNING After the airbag deploys, the airbag parts are hot. There is a risk of injury. Do not touch the airbag parts. Have a deployed airbag replaced at a qualified specialist workshop as soon as possible. G WARNING Pyrotechnic seat belt tensioners that have been deployed are no longer operational and are unable to perform their intended protective function. This poses an increased risk of injury or even fatal injury. Therefore, have pyrotechnic belt tensioners which have been triggered immediately replaced at a qualified specialist workshop. Mercedes-Benz recommends that after an accident, you have your vehicle towed to a qualified specialist workshop. This is particularly important after the seat belt tensioners have been triggered or after airbags have been deployed. An electric motor is used by PRE-SAFE® to trigger the tightening of the seat belt in hazardous situations. This procedure is reversible. If belt tensioners are triggered or the airbags are deployed, you will hear a bang, and a small amount of powder may also be released. The 6 restraint system warning lamp lights up. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard but can cause short-term breathing difficulties for people with asthma or breathing problems. If it is safe to do so, leave the vehicle immediately or open a window to avoid experiencing potential breathing difficulties. Mode of operation During the first stage of a collision, the restraint system control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the seat belt tensioner is triggered by the restraint system control unit in the event of a frontal or rear collision. The belt tensioner can only be triggered if: Rthe ignition is switched on Rthe components of the restraint system are operational; see the "Restraint system warning lamp" section (Y page 43) Rthe seat belt buckle tongue is engaged in the belt buckle on your front seat The belt tensioners in the rear compartment are triggered independently of the lock status of the seat belts. In certain frontal collision situations, further components of the restraint system are activated independently of each other if the restraint system control unit determines that the accident is severe: Rfront airbags and driver's kneebag if it is determined that it can offer additional protection to the seat belt for vehicle occupants Depending on the classification of the person in the front-passenger seat, the frontRwindowbag, Z 51 Safety Occupant safety Safety 52 Occupant safety passenger front airbag is disabled or enabled. Only when the PASSENGER AIR BAG OFF indicator lamp is not lit, can the co-driver's airbag be deployed in the event of an accident. Observe the information on the PASSENGER AIR BAG OFF indicator lamp (Y page 43). Your vehicle has two-stage front airbags. In the first deployment stage, the front airbag is filled with propellant gas to reduce the risk of injuries. The front airbag is fully deployed if a second deployment threshold is reached within a few milliseconds. The evaluation of the activation threshold for a seat belt tensioner and airbag involves an assessment of the deceleration or acceleration dynamics that occur at different points on the vehicle. This process functions preemptively. Deployment must take place promptly at the beginning of the collision. The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by: Rthe distribution of the force during the impact Rthe collision angle Rthe deformation characteristics of the vehicle Rthe characteristics of the object with which the vehicle has collided Factors which can only be seen and measured after the collision has occurred do not play a decisive role in the deployment of an airbag, nor do they provide an indication of airbag deployment. The vehicle can be substantially deformed without the driver's airbag being deployed. This is the case if only relatively easily deformable vehicle parts are affected by the collision and a high deceleration threshold is not reached. On the other hand, airbags may be deployed even though the vehicle only displays minor deformation. This is the case if, for example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs as a result. When the restraint system control unit detects a side impact or determines that the vehicle has overturned, the corresponding components of the restraint system are activated independently of each other, depending on the type of accident that has occurred. If the system determines in this situation that it can offer additional protection for vehicle occupants, the seat belt tensioners are also triggered. RSidebags and pelvisbag on the side on which impact occurs, independent of the belt tensioner and seat belt use Vehicles with automatic child seat recognition in the co-driver's seat: the sidebag and pelvisbag on the co-driver's side deploy under the following conditions: - an occupant is detected on the co-driver's seat, or - the seat belt buckle tongue is engaged in the belt buckle on the co-driver's seat RThe windowbag on the side on which impact occurs, independent of seat belt use and regardless of whether the co-driver's seat is occupied RWindowbags on the driver's and co-driver's sides in certain situations where the vehicle overturns, if it is determined that they can offer additional protection to the seat belt for vehicle occupants i Not all airbags are deployed in an acci- dent. The various airbag systems work independently of one another. How the airbag system works is determined by the severity of the accident detected, especially the vehicle deceleration or acceleration, and the apparent type of accident: Rfrontal collision impact Roverturn Rside Occupant safety Important safety notes G WARNING The function of the head restraint may be impaired if you: Rattach objects such as coat hangers to the head restraints, for example Ruse unsuitable head restraint covers If you do so, the head restraints cannot fulfil their intended protective function in the event of an accident. In addition, objects attached to the head restraints could endanger other vehicle occupants. This poses an increased risk of injury. Do not attach any objects to the head restraints and only use suitable head restraint covers. Consult a Mercedes-Benz Service Centre regarding the availability of suitable seat or head restraint covers. Operation NECK-PRO head restraints/NECK-PRO luxury head restraints offer additional protection against head and chest injuries. In the event of a rear collision of a certain severity, the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and frontpassenger seats are moved forwards and upwards. This provides better head support. If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats (Y page 54). Otherwise, the additional protection will not be available in the event of another rear-end collision. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted. Mercedes-Benz recommends that you have the functionality of the NECK-PRO head restraints/NECK-PRO luxury head restraints checked at a qualified specialist workshop after a rear-end collision. Resetting a triggered NECK-PRO head restraint/NECK-PRO luxury head restraint NECK-PRO head restraints Example: Coupé Do not insert your finger between the upholstery of the head restraint and the cover. Pay particular attention while resetting the NECKPRO head restraints. X Tilt the top of the NECK-PRO head restraint cushion forwards in the direction of arrow :.

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: RABS X To activate/deactivate: press button ;. If indicator lamp : is lit, operation of the rear side windows is disabled. Operation is 69 (Anti-lock Braking System) (Y page 70) RBAS (Brake Assist System) (Y page 70) RBAS PLUS (Brake Assist System PLUS) (Y page 71) RAdaptive brake lamps (Y page 72) RESP® (Electronic Stability Program) (Y page 72) REBD (electronic brake force distribution) (Y page 76) RADAPTIVE BRAKE (Y page 76) RPRE-SAFE® Brake (Y page 76) Z 70 Driving safety systems Safety Important safety notes If you fail to adapt your driving style or if you are inattentive, the driving safety systems can neither reduce the risk of an accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road, weather and traffic conditions and maintain a safe distance from the vehicle in front. Drive carefully. i The driving safety systems described only work as effectively as possible when there is adequate contact between the tyres and the road surface. Please pay special attention to the notes on tyres, recommended minimum tyre tread depths etc. (Y page 364). In wintry driving conditions, always use winter tyres (M+S tyres) and, if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible. ABS (Anti-lock Braking System) General notes ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. The yellow ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. Important safety notes i Observe the "Important safety notes" section (Y page 70). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop. If ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 289) and display messages which may be shown in the instrument cluster (Y page 262). ABS works from a speed of about 8 km/hupwards, regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. Brakes If ABS intervenes: continue to depress the brake pedal with force until the braking situation is over. X To make a full brake application: depress the brake pedal with full force. X If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions; this serves as a reminder to take extra care while driving. BAS (Brake Assist) General notes BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. Driving safety systems i Observe the "Important safety notes" section (Y page 70). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking. Braking X Keep the brake pedal depressed firmly until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System Plus) General notes i Observe the "Important safety notes" section (Y page 70). Important safety notes G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. In such cases, BAS PLUS may: Rintervene unnecessarily intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. Rnot G WARNING BAS PLUS does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto BAS PLUS is only available on vehicles with DISTRONIC PLUS. For BAS PLUS to assist you, the radar sensor system must be: In the event of snowfall or heavy rain, detection can be impaired. Detection by the radar sensor system is also impaired in the event of: Ractivated (Y Rdirt page 255) Roperational With the aid of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. If the radar sensor system is malfunctioning, BAS PLUS will not be available. The brake system is still available with complete brake boosting effect and BAS. on the sensors or obscured sensors by other radar sources Rstrong radar reflections, for example, in multi-storey car parks Ra narrow vehicle travelling in front, e.g. a motorcycle Ra vehicle travelling in front on a different line Following damage to the front end of the vehicle, have the radar sensor settings and operation checked at a qualified specialist workshop. This also applies to collisions at slow speeds where there is no visible damage to the front of the vehicle. Rinterference Z Safety Important safety notes 71 Driving safety systems 72 Function To avoid a collision, BAS PLUS calculates the brake force necessary if: Safety Ryou approach an obstacle and PLUS has detected a risk of collision When driving at a speed under 30 km/h: if you depress the brake pedal, BAS PLUS is activated. Braking assistance from BAS PLUS is carried out at the last possible moment. When driving at a speed above 30 km/h: if you depress the brake pedal sharply, BAS PLUS automatically increases the brake pressure to a degree suited to the traffic situation. BAS PLUS provides braking assistance in hazardous situations at speeds above 7 km/h. At speeds of up to approximately 70 km/h, BAS PLUS can also detect stationary objects. Examples of stationary objects are stopped or parked vehicles. RBAS i If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. BAS PLUS is deactivated and the brakes function as usual, if: Ryou release the brake pedal is no longer a risk of collision Rno obstacle is detected in front of your vehicle Rthere Adaptive brake lamps i Observe the "Important safety notes" section (Y page 70). The adaptive brake lights warn following traffic in an emergency braking situation: Rby flashing brake lamps hazard warning lamps are activated Rthe If you brake sharply from a speed of more than 50 km/h or if braking is assisted by BAS or BAS PLUS, the brake lamps flash rapidly. In this way, traffic travelling behind you is warned in an even more noticeable manner. If you brake sharply from a speed of more than 70 km/h to a standstill, the hazard warning lamps are activated automatically. If the brakes are applied again, the brake lamps light up continuously. The hazard warning lamps switch off automatically if you travel faster than 10 km/h. You can also switch off the hazard warning lamps using the hazard warning button (Y page 126). ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes" section (Y page 70). ESP® monitors driving stability and traction, i.e. power transmission between the tyres and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilise the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilise the vehicle during braking. ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is transferred to the wheel or wheels with traction. Traction control remains active if you deactivate ESP®. Important safety notes Characteristics of ESP® i Observe the "Important safety notes" sec- General notes If the ÷ ESP warning lamp goes out before beginning the journey, ESP® is automatically active. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. tion (Y page 70). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilise the vehicle. In addition, other driving safety systems are switched off. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop. ! Vehicles with 4MATIC: switch off the ignition when the parking brake is being tested using a dynamometer. Application of the brakes by ESP® may otherwise destroy the brake system. ! Vehicles with 4MATIC: function or per- formance tests may only be carried out on a 2-axle dynamometer. Before operating the vehicle on such a dynamometer, please consult a qualified specialist workshop. You could otherwise damage the drive train or the brake system. Vehicles without 4MATIC: when towing your vehicle with the rear axle raised, it is important that you observe the notes on ESP® (Y page 359). ESP® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 291) and display messages which may be shown in the instrument cluster (Y page 262). i Only use wheels with the recommended tyre sizes. Only then will ESP® function properly. If ESP® intervenes: Do not deactivate ESP® under any circumstances. X When pulling away, only depress the accelerator pedal as far as is necessary. X Adapt your driving style to suit the prevailing road and weather conditions. X ECO start/stop function The ECO start/stop function switches the engine off automatically if the vehicle stops moving. When pulling away again, the engine starts automatically. ESP® remains in its previously selected status. Example: if ESP® was deactivated before the engine was switched off, ESP® remains deactivated when the engine is switched on again. Deactivating/activating ESP® (except AMG vehicles) Important safety notes You can select between the following statuses of ESP: RESP® RESP® is activated is deactivated G WARNING If you deactivate ESP®, ESP® no longer stabilises the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following. Z 73 Safety Driving safety systems Driving safety systems 74 It may be best to deactivate ESP® in the following situations: Rwhen using snow chains deep snow Ron sand or gravel Safety Rin i Activate ESP® as soon as the situations described above no longer apply.

ESP® slows the vehicle down by braking and limiting the engine output until the vehicle/trailer combination has stabilised. Important safety notes G WARNING If road and weather conditions are poor, trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerving. Trailers with a high centre of gravity can tip over before ESP® can detect this. There is a risk of an accident. Always adapt your driving style to the prevailing road and weather conditions. If your vehicle/trailer combination begins to lurch, you can only stabilise the vehicle/ trailer combination by depressing the brake firmly. ESP® trailer stabilisation is active above speeds of about 65 km/h. Z Safety To activate SPORT handling mode: briefly press button :.

PRE-SAFE® Brake General notes Safety i Observe the "Important safety notes" secEBD (electronic brake force distribution) General notes EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. Important safety notes i Observe the "Important safety notes" sec- tion for driving safety systems (Y page 70). G WARNING If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop. Observe information regarding indicator and warning lamps (Y page 289) as well as display messages (Y page 264). ADAPTIVE BRAKE i Observe the "Important safety notes" section (Y page 70). ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 200) and hill start assist (Y page 162). tion (Y page 70). PRE-SAFE® Brake is only available on vehicles with DISTRONIC PLUS. For PRE-SAFE® Brake to assist you when driving, the radar sensor system must be: Ractivated (Y page 255) Roperational With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. PRE-SAFE® Brake can help you to minimise the risk of a collision with a vehicle ahead or reduce the effects of such a collision. If PRESAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. Important safety notes G WARNING PRE-SAFE® Brake will initially brake your vehicle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you also brake. Automatic emergency braking cannot prevent a collision. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then brake the vehicle Rneither give a warning nor intervene There is a risk of an accident. Driving safety systems In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. G WARNING PRE-SAFE® Brake does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Rto As a result, PRE-SAFE® Brake may neither give warnings nor intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. In the event of snowfall or heavy rain, detection can be impaired. Detection by the radar sensor system is also impaired in the event of: Rdirt on the sensors or obscured sensors by other radar sources Rstrong radar reflections, for example, in multi-storey car parks Ra narrow vehicle travelling in front, e.g. a motorcycle Ra vehicle travelling in front on a different line Following damage to the front end of the vehicle, have the radar sensor settings and operation checked at a qualified specialist workshop. This also applies to collisions at slow speeds where there is no visible damage to the front of the vehicle. Rinterference Function X To activate/deactivate: activate or deactivate PRE-SAFE® Brake in the on-board computer (Y page 250). If the PRE-SAFE® Brake is not activated, the æ symbol appears in the multifunction display. This function will issue a warning if: Rat a speed of around 30 km/h or more the distance maintained to the vehicle travelling in front is insufficient for several seconds. The · distance warning lamp then lights up in the instrument cluster. Rat a speed of approximately 7 km/h or more, you rapidly approach a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. X Brake immediately to defuse the situation. or X Take evasive action provided it is safe to do so. The PRE-SAFE® Brake function can also brake the vehicle automatically under the following conditions: Rthe driver and front passenger have their seat belts fastened and Rthe vehicle speed is between approximately 7 km/h and 200 km/h At speeds of up to approximately 70 km/h PRE-SAFE® Brake can also detect stationary objects. Examples of stationary objects are stopped or parked vehicles. You can prevent the intervention of PRESAFE® Brake at any time by: Rdepressing the accelerator pedal further kickdown Rreleasing the brake pedal Ractivating Z Safety Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation. 77 78 Anti-theft systems The braking action of PRE-SAFE® Brake is ended automatically if: manoeuvre to avoid the obstacle is no longer any danger of a collision Rthere is no longer an obstacle detected in front of your vehicle If you approach an obstacle and PRE-SAFE® Brake detects a risk of a collision, the system will alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventive passenger protection measures (PRE-SAFE®) are activated (Y page 54). If a risk of collision remains at speeds over 30 km/h and you do not brake, take evasive action or significantly accelerate, automatic braking may be performed up to a level of automatic emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided.

Setting the exterior lighting Setting options Exterior lighting can be set by: Rusing the light switch the combination switch (Y page 125) Rusing the on-board computer (Y page 253) Rusing Light switch Operation Driving abroad Symmetrical dipped-beam headlamps If your journey takes you to countries where vehicles are driven on the opposite side of the road to the country in which the vehicle is registered, your headlamps must be switched to symmetrical dipped beam. This prevents oncoming traffic from being dazzled. Symmetrical lights do not illuminate as large an area of the edge of the carriageway. Convert the headlamps as close to the border as possible before driving in these countries (Y page 253). Asymmetrical dipped-beam headlamps Convert the headlamps back to asymmetrical dipped beam as soon as possible after crossing the border (Y page 253). 1 W Left-hand parking lamps 2 X Right-hand parking lamps 3 T Side lamps, licence plate and instru- ment cluster lighting 4 à Automatic headlamp mode, control- led by the light sensor 5 L Dipped-beam/main-beam head- lamps B R Rear foglamp If you hear a warning tone when you leave the vehicle, the lights may still be switched on.

Rthe operate even if the ignition is switched off. Headlamp cleaning system The headlamps are cleaned automatically if the "Wipe with washer fluid" function is operated five times (Y page 133) while the lights are on and the engine is running. When you switch off the ignition, the automatic headlamp cleaning system is reset and counting is resumed from 0. The active light function is a system that moves the headlamps according to the steering movements of the front wheels. In this way, relevant areas remain illuminated while driving. This allows you to recognise pedestrians, cyclists and animals. Active: when the lights are switched on. Cornering light function Intelligent Light System General notes The Intelligent Light System is a system that adjusts the headlamps automatically to suit the prevailing driving and weather conditions. It offers advanced functions for improved illumination of the road surface, e.g. depending on the vehicle speed or weather conditions. The system includes the active light function, cornering light function, motorway mode and extended range foglamps. The system is only active when it is dark. You can activate or deactivate the "Intelligent Light System" using the on-board computer (Y page 253). The cornering light function improves the illumination of the road over a wide angle in the direction you are turning, enabling better visibility in tight bends, for example. It can only be activated when the dipped-beam headlamps are switched on. Active: Rif you are driving at speeds below 40 km/h and switch on the turn signal or turn the steering wheel Rif you are driving at speeds between 40 km/h and 70 km/h and turn the steering wheel Z Lights and windscreen wipers i The hazard warning lamps continue to 128 Exterior lighting Not active: if you are driving at speeds above 70 km/h or switch off the turn signal or turn the steering wheel to the straight-ahead position. The cornering lamp may remain lit for a short time, but is automatically switched off after no more than three minutes. Not active: if, following activation, you are driving at speeds above 100 km/h or if you switch off the rear foglamp. Adaptive Highbeam Assist General notes Lights and windscreen wipers Motorway mode Active: if you are driving at a speed above 110 km/h and do not make any large steering movements for at least 1,000 m or if you are driving at a speed above 130 km/h. Not active: if you are driving at speeds below 80 km/h following activation. Extended range foglamps The extended range foglamps reduce the glare experienced by the driver and improve the illumination of the edge of the carriageway. Active: if you are driving at speeds below 70 km/h and you switch on the rear foglamp. You can use this function to set the headlamps to change between dipped beam and main beam automatically. The system recognises vehicles with their lights on, either approaching from the opposite direction or travelling in front of your vehicle, and consequently switches the headlamps from main beam to dipped beam. The system automatically adapts the dippedbeam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it switches on the main-beam headlamps again. The system's optical sensor is located behind the windscreen near the overhead control panel. Exterior lighting G WARNING Adaptive Highbeam Assist does not recognise road users: Rwho have no lights, e.g. pedestrians have poor lighting, e.g. cyclists Rwhose lighting is blocked, e.g. by a barrier In very rare cases, Adaptive Highbeam Assist recognises road users too late or not at all. In this, or in similar situations, the automatic main-beam headlamps will not be deactivated or activated regardless. There is a risk of an accident. Always carefully observe the traffic conditions and switch off the main-beam headlamps in good time. Rwho Adaptive Highbeam Assist cannot take into account road, weather or traffic conditions. Adaptive Highbeam Assist is only an aid. You are responsible for adjusting the vehicle's lighting to the prevailing light, visibility and traffic conditions.

You can get an electric shock if you remove the cover of the xenon bulb and touch the electrical contacts. There is a risk of fatal injury. Never touch the parts or the electrical contacts of the xenon bulb. Always have work on the xenon bulbs carried out at a qualified specialist workshop. If your vehicle is equipped with xenon bulbs, you can recognise this by the following: the cone of light from the xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be observed, the lights must be switched on before the engine is started. G WARNING Bulbs, lamps and plug connectors can become very hot during use. When replacing a bulb, you could burn yourself on these components. There is a risk of injury. Allow these components to cool down before replacing the bulb. Do not use a bulb that has been dropped or if its glass tube has been scratched. The bulb may explode if: Ryou Rit touch it is hot Z Lights and windscreen wipers X 132 Replacing bulbs Ryou drop it scratch it Only operate bulbs in enclosed lamps designed for that purpose. Only fit spare bulbs of the same type and the specified voltage. Marks on the glass tube reduce the service life of the bulbs. Do not touch the glass tube with your bare hands. If necessary, clean the glass tube when cold with alcohol or spirit and rub it off with a lint-free cloth. Protect bulbs from moisture during operation. Do not allow bulbs to come into contact with liquids. You can neither replace xenon bulbs nor LED bulbs. Have LED bulbs replaced at a qualified specialist workshop. Replace only the bulbs listed (Y page 132). Have the bulbs that you cannot replace yourself replaced at a qualified specialist workshop. If you require assistance replacing bulbs, consult a qualified specialist workshop. If the new bulb still does not light up, consult a qualified specialist workshop.

To prevent the windows from misting up: Rswitch Rswitch briefly off climate control only briefly on air-recirculation mode only Rswitch on the cooling with air dehumidification function Rswitch on the "demist windscreen" function briefly, if required Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control is only operational when the engine is running. Optimum operation is only achieved when the side windows and the roof are closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 149). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 97). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly. i The integrated filter filters out most par- ticles of dust and soot and completely filters out pollen. It also reduces gaseous pollutants and odours. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Service Booklet. As this depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. Overview of climate control systems 139 : ; = ?

Auxiliary heating Important safety notes Climate control G DANGER If the exhaust pipe is blocked or sufficient ventilation is not possible, toxic exhaust fumes can enter the vehicle, especially carbon monoxide. This is the case, e.g. in enclosed spaces, or if the vehicle is stuck in snow. There is a risk of fatal injuries. You should switch off the auxiliary heating in enclosed spaces which do not have an extraction system, e.g. a garage. If the vehicle is stuck in snow and you must leave the auxiliary heating running, keep the exhaust pipe and the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open a window on the side of the vehicle away from the wind. G WARNING When the auxiliary heating is switched on, parts of the vehicle can become very hot. Flammable materials such as leaves, grass or twigs may ignite if they come into contact with: i Switch the auxiliary heating on regularly once a month for about ten minutes. The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs without using the heat of the running engine. The auxiliary heating is operated directly using the vehicle's fuel. For this reason, the tank content must be at least at reserve fuel level to ensure that the auxiliary heating functions. The auxiliary heating/ventilation automatically adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating could switch from ventilation mode to heating mode or from heating mode to ventilation mode. The auxiliary heating switches off automatically after 50 minutes. This time limit can be altered. To do this, visit a qualified specialist workshop.

Running-in notes Important safety notes In certain driving and driving safety systems, the sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in procedure. Brake pads/linings and discs that are either new or have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal. The first 1500 km If you treat the engine with sufficient care from the very start, you will be rewarded with excellent performance for the remainder of the engine's life. RDrive at varying road speeds and engine speeds for the first 1500 km. RAvoid overstraining the vehicle during this period, e.g. driving at full throttle. RChange gear in good time, before the rev counter needle is Ô of the way to the red area of the rev counter. RDo not shift down a gear manually in order to brake. RTry to avoid depressing the accelerator pedal beyond the point of resistance (kickdown). After 1500 km, you may gradually accelerate the vehicle to full road and engine speeds. Additional running-in notes for AMG vehicles: RDo not drive at speeds above 140 km/h for the first 1500 km. allow the engine to reach a maximum engine speed of 4500 rpm briefly. ROnly i You should also observe these notes on running-in if the engine or parts of the drive train on your vehicle have been replaced. AMG vehicles with self-locking rear axle differential Your vehicle is equipped with a self-locking differential on the rear axle. Change the oil after a running-in period of 3000 km to improve protection of the rear axle differential. This oil change prolongs the service life of the differential. Have the oil change carried out at a qualified specialist workshop. Driving Important safety notes G WARNING Objects in the driver's footwell may restrict the clearance around the pedals or block a depressed pedal. This jeopardises the operating and road safety of the vehicle. There is a risk of an accident. Stow all objects securely in the vehicle so that they do not get into the driver's footwell. Always fit the floormats securely and as prescribed in order to ensure that there is always sufficient room for the pedals. Do not use loose floormats and do not place several floormats on top of one another. Driving Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals. Rshoes G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. G WARNING If the parking brake has not been fully released when driving, the parking brake can: Roverheat and cause a fire Rlose its hold function. There is a risk of fire and an accident. Release the parking brake fully before driving off. ! Warm up the engine quickly.

Driving tips General notes G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. ECO display The brake lights do not light up when you brake the vehicle with the parking brake. X To apply: depress parking brake ; firmly. The J indicator lamp in the instrument cluster lights up if the engine is running. X To release: depress the brake pedal and keep it depressed. X Pull release handle :. The J indicator lamp in the instrument cluster goes out. Parking up the vehicle If you leave the vehicle parked up for longer than four weeks, the battery may be damaged by exhaustive discharging. If you leave the vehicle parked up for longer than six weeks, the vehicle may suffer damage as a result of lack of use. Visit a qualified specialist workshop and seek advice. i You can obtain information about trickle chargers from a qualified specialist workshop. X Example: ECO display The ECO display provides feedback on how economical your driving characteristics are. The ECO display assists you in achieving the most economical driving style for the selected settings and prevailing conditions. Consumption can be significantly influenced by your driving style. The ECO display consists of three bars: RAcceleration RConstant RCoasting The percentage count is the mean value of the three bar values. The three bars and the mean value begin at the value of 50%. A higher percentage count indicates a more economical driving style. The ECO display does not indicate the actual fuel consumption. A fixed percentage count in the ECO display does not indicate a fixed consumption. Driving tips Rload Rtyre pressure start Rchoice of route Rthe use of electrical consumers These factors are not included in the ECO display. The evaluation of your driving style takes the following three categories into consideration: RAcceleration (evaluation of all acceleration processes): - the bar fills up: moderate acceleration, especially at higher speeds - the bar empties: sporty acceleration RConstant (assessment of driving behaviour at all times): - the bar fills up: constant speed and avoidance of unnecessary acceleration and deceleration - the bar empties: fluctuations in speed RCoasting (assessment of all deceleration processes): - the bar fills up: anticipatory driving, keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes - the bar empties: frequent braking Rcold a journey. During a prolonged driving time, these changes are smaller. For more dynamic changes, perform a manual reset. Further information on the ECO display (Y page 244). Brakes Important safety notes G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. This increases the risk of skidding and having an accident. Do not shift down for additional engine braking on a slippery road surface. Downhill gradients Do not depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by constantly applying light pressure to the pedal. This results in excessive and premature wear to the brake pads. Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle and when towing a trailer. i An economical driving style involves driv- i This also applies if you have activated i On long journeys at a constant speed, e.g. This will use the braking effect of the engine, so less braking will be required to maintain vehicle speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. ing at a moderate engine speed. To achieve a higher value in the categories Acceleration and Constant Constant: Robserve the gearshift recommendation Rdrive the vehicle in drive program E on the motorway, only the bar for Constant will change. i The ECO display summarises the driving characteristics from the start of the journey to its completion. Therefore, there are dynamic changes in the bars at the start of cruise control, SPEEDTRONIC or DISTRONIC PLUS. Heavy and light loads G WARNING The braking system can overheat if you leave your foot on the brake pedal while driving. This increases the braking distance and could Z Driving and parking In addition to driving style, the consumption is affected by many other factors, such as: 183 Driving and parking 184 Driving tips even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Do not simultaneously depress both the brake pedal and the accelerator pedal while driving. ! Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly. If the brakes have been used only moderately, you should occasionally test their effectiveness. To do this, brake more firmly from a higher speed while paying attention to the traffic conditions. This improves the grip of the brakes. Wet road surfaces If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after a car wash or after driving through deep water. You will have to depress the brake pedal more firmly. Maintain a greater distance to the vehicle in front. After driving on a wet road or having the vehicle washed, brake firmly while paying attention to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corrosion. Limited braking performance on salttreated roads If you drive on salt-treated roads, a layer of salt may form on the brake discs and pads. This can increase the braking distance considerably. RIn order to prevent any salt build-up, apply the brakes occasionally while paying attention to the traffic conditions. RCarefully depress the brake pedal at the end of the journey and when starting the next journey. RMaintain a much greater distance to the vehicle in front. New brake pads/linings Brake pads/linings and discs that are either new or have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal. For safety reasons, Mercedes-Benz recommends that you only have brake pads/linings fitted to your vehicle which have been approved for Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles or which are not of an equivalent quality could affect your vehicle's operating safety. AMG high-performance and ceramic brakes The high-performance brake system is only available on AMG vehicles. The AMG brake systems are designed for heavy loads. This may lead to noise when braking. This is dependent on: Rspeed Rbraking force Renvironmental conditions, such as temper- ature and humidity The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions. For this reason, it is impossible to state a mileage (service life) that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further Driving tips Driving on wet roads Aquaplaning If water has accumulated to a certain depth on the road surface, there is a danger of aquaplaning occurring, even if: Ryou are driving at low speeds tyres have adequate tread depth For this reason, drive in the following manner in the event of heavy rain or in conditions in which aquaplaning can occur: Rthe Rlower your speed tyre ruts Ravoid sudden steering movements Rbrake carefully Ravoid Driving on flooded roads ! Bear in mind that vehicles travelling in front or in the opposite direction create waves. This may cause the maximum permissible water depth to be exceeded. These notes must be observed under all circumstances. You could otherwise damage the engine, the electronics or the transmission. If you must drive on stretches of road on which water has collected, please bear in mind that: Rthe maximum permissible fording depth in still water is 25 cm Ryou should drive no faster than walking pace Winter driving G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. This increases the risk of skidding and having an accident. Do not shift down for additional engine braking on a slippery road surface. G DANGER If the exhaust pipe is blocked or adequate ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle becomes trapped in snow. There is a risk of fatal injury. If you leave the engine or the auxiliary heating running, make sure the exhaust pipe and area around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind. Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. You should drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking manoeuvres. If the vehicle threatens to skid or cannot be stopped when moving at low speed: Move the transmission to position N. X Try to bring the vehicle under control by using corrective steering. X The outside temperature indicator is not designed to serve as an ice-warning device Z Driving and parking information about this from your MercedesBenz Service Centre. Brake pads/linings and discs that are either new or have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal. Always be aware of this and adapt your driving and braking accordingly during the running-in period. Excessive heavy braking results in correspondingly high brake wear. Observe the brake wear warning lamp in the instrument cluster and note any brake status messages in the multifunction display. If you regularly drive at high speeds, it is particularly important to have the brake system checked and maintained regularly. 185 Driving and parking 186 Driving systems and is therefore unsuitable for that purpose. Changes in the outside temperature are displayed after a short delay. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could skid if you fail to adapt your driving style. Always adapt your driving style and drive at a speed to suit the prevailing weather conditions. You should pay special attention to road conditions when temperatures are around the freezing point.

Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in the lane. Do not use cruise control: Rin road and traffic conditions which do not allow you to maintain a constant speed (e.g. in heavy traffic or on winding roads) Ron smooth or slippery roads. Braking or accelerating can cause the drive wheels to lose traction and the vehicle could then skid Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow If there is a change of drivers, advise the new driver of the speed stored. Cruise control lever Driving systems Cruise control General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. You must select a low gear in good time on long and steep downhill gradients, especially if the vehicle is laden or towing a trailer (CLS Shooting Brake only). By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Use cruise control only if road and traffic conditions are appropriate for maintaining a steady speed for a prolonged period. You can store any road speed above 30 km/h.

If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 30 km/h and 200 km/h. If a vehicle is driving in front of you, it operates in the speed range between 0 km/h and 200 km/h. Do not use DISTRONIC PLUS while driving on roads with steep gradients. Important safety notes G WARNING DISTRONIC PLUS does not react to: Rpeople or animals Rstationary obstacles on the road, e.g. stop- ped or parked vehicles and crossing traffic As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Roncoming G WARNING DISTRONIC PLUS cannot always clearly identify other road users and complex traffic situations. In such cases, DISTRONIC PLUS may: Rgive an unnecessary warning and then brake the vehicle Rneither give a warning nor intervene Raccelerate unexpectedly There is a risk of an accident. Continue to drive carefully and be ready to brake, in particular when warned to do so by DISTRONIC PLUS. G WARNING DISTRONIC PLUS brakes your vehicle with up to 40% of the maximum braking force. If this braking force is insufficient, DISTRONIC PLUS warns you visually and audibly. There is a risk of an accident. In such cases, apply the brakes yourself and try to take evasive action. ! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automatically in certain situations. To prevent damage to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in the following or other similar situations: Rwhen Rin towing the vehicle the car wash If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of an accident nor override the laws of physics.

Vehicles with COMAND Online i The vehicle can also pull away when it is facing an unidentified obstacle or is driving on a different line from another vehicle. The vehicle then brakes automatically. There is a risk of an accident. Be ready to brake at all times. If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained. If DISTRONIC PLUS detects a faster-moving vehicle in front, it increases the driving speed. However, the vehicle is only accelerated up to the speed you have stored. Example: roundabout i The following function is not operational in all countries. DISTRONIC PLUS uses additional information from your navigation system so that it can adapt to certain traffic situations. This is the case if, while following a vehicle, DISTRONIC PLUS is active and you: Rapproach or drive around a roundabout a T-junction Rturn off at a motorway exit Rapproach Z Driving and parking Ryou RDISTRONIC Driving and parking 196 Driving systems Even if the vehicle in front leaves the detection range, DISTRONIC PLUS temporarily maintains the current driving speed and does not accelerate. This is based on the current map data in the navigation system. Afterwards, the vehicle accelerates back to the speed you set. Stopping G WARNING When leaving the vehicle, even if it is braked only by DISTRONIC PLUS, it could roll away if: Rthere is a malfunction in the system or in the voltage supply. RDISTRONIC PLUS has been deactivated with the cruise control lever, e.g. by a vehicle occupant or from outside the vehicle. Rthe electrical system in the engine compartment, the battery or the fuses have been tampered with. Rthe battery is disconnected. Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant. There is a risk of an accident. If you wish to exit the vehicle, always turn off DISTRONIC PLUS and secure the vehicle against rolling away. If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. Once your vehicle is stationary, it remains stationary and you do not need to depress the brake. i Depending on the specified minimum dis- tance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. When DISTRONIC PLUS is activated, the transmission is shifted automatically to position P if: Rthe driver's door is open and the driver's seat belt is unfastened Rthe engine is switched off, unless it is automatically switched off by the ECO start/ stop function Rthe bonnet is opened Ra system fault occurs Rthe power supply is insufficient Setting a speed Press the cruise control lever up : for a higher speed or down ; for a lower speed.

There is a danger of injury. When lowering the vehicle, make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches. The vehicle may be lowered if you press the suspension tuning selector button or the AMG button. The vehicle is lowered even if the vehicle is at a standstill. ! If Sport or Sport + suspension tuning has been selected, the vehicle's ground clearance decreases. Make sure that no objects become trapped or that the vehicle has not been damaged, for example, on the kerb. i The vehicle level at the rear axle may change visibly if you park the vehicle and the outside temperature changes. If the temperature drops, the vehicle level lowers; with an increase in temperature, the vehicle level rises. Changing the rear axle level This function is only available for the CLS 63 AMG 4MATIC and CLS 63 AMG Shooting Brake. The vehicle level at the rear axle depends on the selected suspension mode and the vehicle speed. The vehicle level at the rear axle changes while driving depending on which suspension mode is selected: RComfort: +10 mm + and Sport: -15 mm When changing from Comfort to Sport or Sport +, the axle is lowered approximately 25 mm. When changing from Sport or Sport + to Comfort, the axle is raised approximately RSport 25 mm. The level change also occurs when stationary. If you drive faster than 170 km/h, the rear axle level is set to a middle level. This increases road safety and reduces air resistance. If you then drive slower than 150 km/h, the level of the rear axle is again adjusted to correspond to the selected suspension mode. Load compensation The vehicle can compensate differences in the vehicle level by raising or lowering the rear axle. This is the case, for example, when people get out of the vehicle or when luggage is removed. A load compensation occurs if: Ra door or the boot lid/tailgate is opened parked vehicle is unlocked The engine needs to be running for larger level changes. Rthe 4MATIC (permanent all-wheel drive) If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override the laws of physics. 4MATIC cannot take account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in the lane. If a drive wheel spins due to insufficient grip: Rwhen pulling away, only depress the accelerator pedal as far as is necessary Raccelerate less when driving ! Never tow the vehicle with one axle raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz implied warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground. i In wintry driving conditions, the maximum effect of 4MATIC can only be achieved if Driving systems 4MATIC ensures that all four wheels are permanently driven. Together with ESP®, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip. PARKTRONIC Important safety notes PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a substitute for your attention to the immediate surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that there are no persons, animals or objects in range while manoeuvring and parking. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper. Range of the sensors General notes PARKTRONIC does not take into account obstacles located: Rbelow the detection range, e.g. persons, animals or objects Rabove the detection range, e.g. overhanging loads, tail sections or loading ramps of goods vehicles ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and objects which absorb ultrasonic sources. Ultrasonic sources, such as an automatic car wash, a lorry's compressed-air brakes or a pneumatic drill, could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain. : Example: sensors in the front bumper, left-hand side The sensors must be free of dirt, ice and slush. Otherwise, they may not function correctly. Clean the sensors regularly, taking care not to scratch or damage them (Y page 337). PARKTRONIC is activated automatically if you: Rswitch on the ignition the transmission to position D, R or N Rrelease the parking brake PARKTRONIC is deactivated at speeds above 18 km/h. It is reactivated at lower speeds. Rshift Example: side view Z Driving and parking you use winter tyres (M+S tyres), with snow chains if necessary. 207 208 Driving systems Driving and parking Warning displays Example: top view Front sensors Centre Approx. 100 cm Corners Approx. 60 cm Rear sensors Warning display for the front area : Segments on the left-hand side of the vehicle ; Segments on the right-hand side of the vehicle = Segments showing operational readiness Centre Approx. 120 cm Corners Approx. 80 cm Minimum distance Centre Approx. 20 cm Corners Approx. 15 cm If there is an obstacle within this range, the relevant warning displays light up and a warning tone sounds.

A parking symbol indicates a suitable parking space. Active steering intervention can assist you during parking. You may also use PARKTRONIC (Y page 207). Important safety notes Active Parking Assist is only an aid. It is not a substitute for your attention to the immediate surroundings. The responsibility for safe manoeuvring and parking remains with you. Make sure that no persons, animals or objects are in the manoeuvring range. When PARKTRONIC is switched off, Active Parking Assist is also unavailable. G WARNING The vehicle will veer out when parking and can take you onto sections of the oncoming lane. As a result, you may collide with other road users. There is a risk of an accident. When parking, pay attention to other road users. Stop the vehicle if necessary or cancel the Active Parking Assist parking procedure. ! If unavoidable, you should drive over obstacles such as kerbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tyres. Active Parking Assist may also display spaces not suitable for parking, e.g.: Rparking or stopping prohibitions Rin front of driveways or entrances and exits Runsuitable surfaces Parking tips: Ron narrow roads, drive as closely as possible past the parking space. Rparking spaces that are littered or overgrown might be identified or measured incorrectly. Rparking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. Rsnowfall or heavy rain may lead to a parking space being measured inaccurately. Rpay attention to the PARKTRONIC (Y page 208) warning messages during the parking procedure. Rat any time, you can intervene in the steering procedure to correct it. Active Parking Assist will then be cancelled. Rwhen transporting a load which protrudes from your vehicle, you should not use Active Parking Assist. Rnever use Active Parking Assist when snow chains are fitted. Rmake sure that the tyre pressures are always correct. This has a direct influence on the parking characteristics of the vehicle. Use Active Parking Assist for parking spaces: Rthat are parallel to the direction of travel Rthat are on straight roads, not bends Rthat are on the same level as the road, e.g. not on the pavement Detecting parking spaces Objects located above the height range of Active Parking Assist will not be detected when the parking space is measured. These are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. G WARNING If objects are located above the detection range, Active Parking Assist may start to steer into the parking space too soon. As a result, you could cause a collision. There is a risk of an accident. If objects are located above the detection range, stop the vehicle and switch Active Parking Assist off. For further information on the detection range (Y page 207). Active Parking Assist does not support you parking in spaces that are parallel to the direction of travel if: Rthe parking space is on a kerb stone system reads the parking space as being blocked, for example by foliage or grass paving blocks Rthe area is too small for the vehicle to manoeuvre into Rthe parking space is bordered by an obstacle, e.g. a tree, a post or a trailer Rthe Example: detected parking space : Detected parking space on the left ; Parking symbol = Detected parking space on the right Active Parking Assist is activated automatically when driving forwards. The system is operational at speeds of up to approximately 35 km/h. While in operation, the system independently locates and measures parking spaces on both sides of the vehicle.

Night View Assist Plus camera : picks up the infrared light and displays a monochrome image in COMAND. The image displayed in COMAND corresponds to a road lit up by main-beam headlamps. This enables you to see the road's course and any obstacles in good time. When pedestrian recognition is active, pedestrians recognised by the system are highlighted in the Night View Assist Plus display. Light from the headlamps of oncoming vehicles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the main-beam headlamps due to oncoming traffic. i Infrared light is not visible to the human eye and therefore does not dazzle. Night View Assist Plus can therefore remain switched on even if there is oncoming traffic. X X Make sure COMAND Online is switched on. Press button :. The Night View Assist Plus display appears in the COMAND display. You can read about how to adjust the brightness of the COMAND display in the COMAND Online operating instructions. i The infrared headlamps only switch on when the vehicle is being driven at speeds of at least 10 km/h. This means that you do not have the full visual range while stationary and cannot check whether Night View Assist Plus is working.

X Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 223) and Lane Keeping Assist (Y page 225). Blind Spot Assist General notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from speeds of 30 km/h. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible collision warning. For monitoring, Blind Spot Assist uses sensors in the rear bumper. Important safety notes G WARNING Blind Spot Assist does not react to vehicles: Rovertaken too closely on the side, placing them in the blind spot area Rwhen the difference in the speed of approach and overtaking is too great As a result, Blind Spot Assist cannot warn drivers in these situations. There is a risk of an accident. Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle. Blind Spot Assist is only an aid. It may fail to detect some vehicles and is no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles. Z Driving and parking Problems with Night View Assist Plus 224 Driving systems Monitoring range of the sensors In particular, the detection of obstacles can be impaired in the case of: Driving and parking Rdirt on the sensors or obscured sensors Rpoor visibility, e.g. due to fog, heavy rain, snow or spray Rnarrow vehicles, e.g. motorcycles or bicycles Rvery wide lanes Rnarrow lanes Rvehicles not driving in the middle of their lane Rbarriers or other road boundaries Vehicles in the monitoring range are then not indicated. Due to the nature of the system: Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders Rwarnings may be interrupted when driving alongside long vehicles, for example lorries, for a prolonged time The two radar sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors. The sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the sensors checked at a qualified specialist workshop. Blind Spot Assist may otherwise not work properly. Indicator and warning display : Yellow indicator lamp/red warning lamp CLS Coupé Blind Spot Assist monitors the area up to 3.0 m behind your vehicle and directly next to your vehicle, as shown in the diagram. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles at the edge of their lane nearest your vehicle. Blind Spot Assist is not active at speeds below approximately 30 km/h. Vehicles in the monitoring range are then not indicated. If Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow up to a speed of 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 30 km/h, warning lamp : on the corresponding side lights up red. This warning always occurs when a vehicle enters the blind spot monitoring range from behind or from Driving systems Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the corresponding turn signal, a double warning tone sounds.

Blind Spot Assist is then deactivated. The indicator lamp lights up yellow in the exterior mirrors and the Blind Spot Assist currently unavailable See Owner's Manual message appears in the multifunction display. i You can deactivate the indicator lamps in the exterior mirrors. To do so, you will need to deactivate Blind Spot Assist if: Rthe key is in position 2 in the ignition lock Rthe engine is not running electrical connection to the trailer has been established Rthe Lane Keeping Assist General notes Lane Keeping Assist monitors the area in front of your vehicle by means of camera : at the top of the windscreen. Lane Keeping Assist detects lane markings on the road and can warn you before you leave your lane unintentionally. This function is available in the range between 60 km/h and 200 km/h. A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration through the steering wheel for up to 1.5 seconds. Important safety notes G WARNING Lane Keeping Assist cannot always clearly identify lane markings. In these cases, Lane Keeping Assist may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay particular attention to the traffic situation and keep in lane, especially if Lane Keeping Assist alerts you. Rnot Z Driving and parking the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 12 km/h. The yellow indicator lamp goes out if reverse gear is engaged. Blind Spot Assist is then deactivated. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. 225 226 Driving systems Driving and parking G WARNING The Lane Keeping Assist warning does not return the vehicle to the original lane. There is a risk of an accident. Always steer, apply the brakes or accelerate the vehicle yourself, especially if Lane Keeping Assist alerts you. If you fail to adapt your driving style, Lane Keeping Assist can neither reduce the risk of an accident nor override the laws of physics. Lane Keeping Assist cannot take into account road, weather or traffic conditions. Lane Keeping Assist is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in lane. Lane Keeping Assist does not keep your vehicle in its lane. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflection from other vehicles (e.g. if the road surface is wet) Rthe windscreen is dirty, misted up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rno, or several, unclear lane markings are present for one lane, e.g. in a construction area Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Rthe road is narrow and winding Rthere are highly variable shade conditions on the road Activating Lane Keeping Assist X Activate Lane Keeping Assist using the onboard computer; to do so, select Standard or Adaptive (Y page 251).

Active Blind Spot Assist General notes Active Blind Spot Assist monitors the areas on either side of the vehicle that are not visible to the driver with two lateral, rear-facing radar sensors. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lanes, you will also receive a visual and audible collision warning. If a risk of side impact is detected, corrective braking may help you avoid a collision. Active Blind Spot Assist evaluates the free space in the direction of travel and to the side before making a course-correcting brake application. For this, Active Blind Spot Assist uses the forwardfacing radar sensors. Active Blind Spot Assist supports you from a speed of approximately 30 km/h. As a result, Active Blind Spot Assist may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic situation and maintain a safe distance at the side of the vehicle. Radar sensors The Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers and behind a cover in the radiator grille. Make sure that the bumpers and the cover in the radiator grille are free of dirt, ice or slush. The rear sensors must not be covered, e.g. by bicycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop. Active Blind Spot Assist may otherwise no longer function properly. Monitoring range G WARNING Active Blind Spot Assist does not detect all traffic situations and road users. There is a risk of an accident. Always make sure that there is sufficient distance to the side for other traffic or obstacles. Important safety notes Active Blind Spot Assist is only an aid and is not a substitute for attentive driving.

Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles at the edge of their lane. Due to the nature of the system: Rpoor Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders Rwarnings may be interrupted when driving alongside long vehicles, for example lorries, for a prolonged time Indicator and warning display If Active Blind Spot Assist is switched on, indicator lamp : in the exterior mirrors lights up yellow up to a speed of 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and Active Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 30 km/h, warning lamp : on the corresponding side lights up red. A warning is always issued when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 12 km/h. The yellow indicator lamp goes out if reverse gear is engaged. Active Blind Spot Assist is then no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light.

Ra driving safety system intervenes, such as ABS, BAS or ESP®. Ryou accelerate hard, e.g. kickdown. Ryou brake hard. Ryou steer actively, e.g. swerve to avoid an obstacle or change lane quickly. Ryou cut the corner on a sharp bend. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognises certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a bend Rthe road has very wide lanes, e.g. a motorway Rthe system recognises solid lane markings The warning vibration occurs later if: Rthe road has narrow lanes Ryou cut the corner on a bend Towing a trailer If you attach a trailer, make sure that you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. Towing a trailer Important safety notes G WARNING The braking system can overheat if you leave your foot on the brake pedal while driving. This increases the braking distance and could even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Do not simultaneously depress both the brake pedal and the accelerator pedal while driving. G WARNING You could lose control of the vehicle/trailer combination if it begins to swerve. The vehicle/trailer combination could even overturn. There is a risk of an accident. On no account should you attempt to straighten out the vehicle/trailer combination by increasing speed. Decrease your speed and do not countersteer. Brake if necessary. G WARNING If the maximum the permissible load for a carrier system is exceeded, the carrier could come loose from the vehicle and endanger other road users. There is a risk of an accident and injury. Never exceed the permissible noseweight when using a carrier. ! Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. If you exceed the maximum permissible noseweight of the trailer drawbar on the ball coupling, the following may become damaged: Ryour vehicle trailer Rthe ball coupling RTrailer tow hitch The vehicle/trailer combination could become unstable. Rthe Towing a trailer Rmake sure to check the noseweight before each journey. Ruse a drawbar noseweight as close as possible to the maximum noseweight. Rdo not exceed the maximum permissible noseweight. Rdo not use a noseweight lower than the minimum permissible trailer drawbar noseweight. When reversing the vehicle towards the trailer, make sure there is nobody between the trailer and the vehicle. Couple and uncouple the trailer carefully. If you do not couple the trailer to the towing vehicle correctly, the trailer could become detached. Make sure that the following values are not exceeded: Rthe permissible trailer drawbar noseweight Rthe permissible trailer load Rthe permissible rear axle load of the towing vehicle maximum permissible gross vehicle weight of both the towing vehicle and the trailer You will find the applicable permissible values, which must not be exceeded, in the vehicle documents. You will find the values approved by the manufacturer on the vehicle identification plates and those for the towing vehicle under "Technical data" (Y page 410). When towing a trailer, your vehicle's handling characteristics will be different in comparison to when driving without a trailer. The vehicle/trailer combination: Rthe Ris heavier restricted in its acceleration and gradient-climbing capability Ris Rhas an increased braking distance affected more by strong crosswinds Rdemands more sensitive steering Rhas a larger turning circle This can impair the vehicle's handling characteristics. Adapt your style of driving accordingly. Maintain a safe distance. Drive carefully. When towing a trailer, always adjust your speed to the current road and weather conditions. Do not exceed the maximum permissible speed for your vehicle/trailer combination. Ris Notes on towing a trailer General notes i When towing a trailer, set the tyre pres- sure on the rear axle of the towing vehicle for a maximum load; see the tyre pressure table in the fuel filler flap (Y page 367). Please note that when towing a trailer, PARKTRONIC (Y page 207), Active Parking Assist (Y page 210) and Blind Spot Assist (Y page 223) are only available with limitations, or not at all. i On vehicles without level control, the height of the ball coupling will alter according to the load placed on the vehicle. If necessary, use a trailer with a height-adjustable drawbar. You will find fitting dimensions and loads under "Technical data" (Y page 409). Driving tips i Observe the notes on ESP® trailer stabilisation (Y page 75). The maximum permissible speed for vehicle/ trailer combinations depends on the type of trailer. Before beginning the journey, check the trailer's documents to see what the maximum permitted speed is. Observe the legally Z Driving and parking If the noseweight used is lower than the minimum permissible noseweight, the vehicle/ trailer combination could also become unstable. To avoid hazardous situations: 233 Towing a trailer Driving and parking 234 prescribed maximum speed in the relevant country. For certain Mercedes-Benz vehicles, the maximum permissible rear axle load is increased when towing a trailer. See "Technical data" to find out whether this applies to your vehicle (Y page 410). If you utilise any of the added maximum rear axle load when towing a trailer, the vehicle/trailer combination may not exceed a maximum speed of 100 km/h for reasons concerning the operating permit. This also applies in countries in which the permissible maximum speed for vehicle/ trailer combinations is above 100 km/h. When towing a trailer, your vehicle's handling characteristics will be different in comparison to when driving without a trailer and it will consume more fuel. Change into a lower gear in good time on long and steep downhill gradients. i This also applies if you have activated cruise control, SPEEDTRONIC or DISTRONIC PLUS. This will use the braking effect of the engine, so less braking will be required to maintain vehicle speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If you need additional braking, depress the brake pedal repeatedly rather than continuously. level. When driving in mountainous areas, note that the power output of the engine, and consequently the vehicle's gradientclimbing capability, decrease with increasing altitude. Folding out the ball coupling G WARNING If the ball coupling is not correctly engaged, the trailer can detach. There is a risk of an accident. Always engage the ball coupling as described. G WARNING If you release the ball coupling or it does not engage correctly when folding in, it will swing out. Within pivoting range of the ball coupling, there is an increased risk of an accident and injury. Only release the ball coupling if the pivoting range is unobstructed. Always make sure that the ball coupling engages when folding in. Driving tips If the trailer swings from side to side: Do not accelerate. Do not countersteer. X Brake if necessary. X X RMaintain a greater distance from the vehicle in front than when driving without a trailer. RAvoid braking abruptly. If possible, brake gently at first to allow the trailer to run on. Then, increase the braking force rapidly. RThe values given for gradient-climbing capabilities from a standstill refer to sea CLS Shooting Brake Before you can tow a trailer with your vehicle, you must fold out the ball coupling.

You can connect accessories with a power rating of up to 240 W to the permanent power supply and with a power rating of up to 180 W to the power supply that is switched on via the ignition lock. Towing a trailer X To switch the connected power supply on or off: turn the key in the ignition lock to position 2 or 0 respectively (Y page 159). When it leaves the factory, your vehicle's trailer socket is equipped with a permanent power supply and a power supply that is switched on via the ignition lock. The permanent power supply is supplied via trailer socket pin 9. The power supply that is switched on via the ignition lock is supplied via trailer socket pin 10. The trailer's permanent power supply is switched off in the event of low vehicle supply voltage and after six hours at the latest. You can find more information about installing the trailer electrics at a qualified specialist workshop. Bulb failure indicator for LED lamps Fitting the adapter ! Make sure that there is sufficient cable play so that the cable cannot become detached when cornering. Driving and parking The trailer battery may not be charged from the power supply. 237 Open the socket cover. Insert the plug connector with lug : into groove = on the socket. Turn bayonet connection ; clockwise to the stop. X Let the cover engage. X If you are using an adapter cable, secure the cable to the trailer with cable ties. X X i If LED lamps are fitted in the trailer, an error message may appear in the multifunction display even if there is no fault. The reason for the error message could be that the current has fallen below the minimum of 50 mA. To ensure reliable operation of the bulb failure indicator, each LED chain in the trailer lighting must be guaranteed a minimum current of 50 mA. Trailer with 7-pin connector General notes Trailer with 7-pin connector: you can connect to the 13-pin socket on the ball coupling using an adapter or, if necessary, an adapter cable.

Operation Information on driving Check the tyre pressures when the vehicle is heavily laden and, if necessary, adjust. While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immediately. Stop the vehicle as soon Operation Regular checking of wheels and tyres G WARNING Damaged tyres can cause tyre inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tyres regularly for signs of damage and replace any damaged tyres immediately. other valve caps or systems, e.g. tyre pressure monitoring systems. Regularly check the pressure of all the tyres, particularly prior to long trips. Adjust the tyre pressure as necessary (Y page 367). Observe the notes on the emergency spare wheel (Y page 390). The service life of tyres depends on various factors, including the following: Rdriving style pressure Rmileage Rtyre Important safety notes on the tyre tread G WARNING Rpunctures Insufficient tyre tread will reduce tyre traction. The tyre is no longer able to dissipate water. This means that on wet road surfaces, the risk of aquaplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at different locations on the tyre tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tyres. Minimum tyre tread depth for: Rtears Rsummer Regularly check the wheels and tyres of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tyre pressure. Pay particular attention to damage such as: Rcuts in the tyres in the tyres on the tyres Rdeformation or severe corrosion on wheels Regularly check the tyre tread depth and the condition of the tread across the whole width of the tyre (Y page 365). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tyre surface. All wheels must have a valve cap to protect the valve against dirt and moisture. Do not fit anything onto the valve other than the standard valve cap or other valve caps approved for your vehicle by Mercedes-Benz. Do not fit any Rbulges tyres: 3 mm tyres: 4 mm For safety reasons, replace the tyres before the legally prescribed limit for the minimum tyre tread depth is reached. RM+S Selecting, fitting and replacing tyres ROnly fit tyres and wheels of the same type and make. Exception: it is permissible to fit a different type or make in the event of a flat tyre. Observe the "MOExtended tyres (tyres with Z Wheels and tyres as possible to check the wheels and tyres for damage. Hidden tyre damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tyres and wheels checked at a qualified specialist workshop. When parking your vehicle, make sure that the tyres do not get deformed by the kerb or other obstacles. If it is necessary to drive over kerbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tyres, particularly the sidewalls, may be damaged. 365 366 Winter operation Wheels and tyres run-flat characteristics)" section (Y page 347). ROnly fit tyres of the correct size onto the wheels. RRun in new tyres at moderate speeds for the first 100 km. They only reach their full performance after this distance. RDo not drive with tyres which have too little tread depth. This otherwise significantly reduces the traction on wet roads (aquaplaning). RReplace the tyres after six years at the latest, regardless of wear. Observe the notes on the emergency spare wheel (Y page 390). MOExtended tyres (tyres with run-flat characteristics) With MOExtended tyres (tyres with run-flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tyres. Only use MOExtended tyres in conjunction with an activated tyre pressure loss warning system or tyre pressure monitoring system and only on tyres specifically inspected by Mercedes‑Benz. Notes on driving with MOExtended tyres with a flat tyre (Y page 347). i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified specialist workshop. Winter operation General notes Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 373). Driving with summer tyres At temperatures below +7 †, summer tyres lose elasticity and therefore traction and braking power. Change the tyres on your vehicle to M+S tyres. Using summer tyres at very cold temperatures could cause tears to form, thereby damaging the tyres permanently. Mercedes-Benz cannot accept responsibility for this type of damage. G WARNING Damaged tyres can cause tyre inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tyres regularly for signs of damage and replace any damaged tyres immediately. M+S tyres G WARNING M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they do not provide sufficient traction. There is a risk of accident. M+S tyres with a tread depth of less than 4 mm must be replaced. At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified by the M+S marking. Only winter tyres bearing the i snowflake symbol in addition to the M+S marking provide the best possible grip in wintry road conditions. Only these tyres will allow driving safety systems such as ABS and ESP® to function optimally in winter. These tyres have been developed specifically for driving in snow. Use M+S tyres of the same make and tread on all wheels to maintain safe handling characteristics. Tyre pressure Check the tyre pressures (Y page 367). Restart the tyre pressure loss warning system (Y page 369). X Restart the tyre pressure monitor (Y page 372). X X For more information on driving with the emergency spare wheel, see (Y page 390). Snow chains G WARNING If you have fitted snow chains to the front wheels, they may scrape against the vehicle body or chassis components. This could cause damage to the vehicle or the tyres. There is a risk of an accident. To avoid hazardous situations: Rnever Rfit fit snow chains on the front wheels snow chains to the rear wheels in pairs. For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz, or that are of a corresponding standard of quality. If you intend to fit snow chains, please bear the following points in mind: Rsnow chains cannot be fitted to all wheeltyre combinations. Permissible wheel-tyre combinations (Y page 378). Ronly use snow chains if the road surface is completely snow-covered. Remove the snow chains as soon as possible when you come to a road that is not snow-covered. Rlocal regulations may restrict the use of snow chains. Observe the appropriate regulations if you wish to fit snow chains. Rdo not exceed the maximum permissible speed of 50 km/h. Ron vehicles with AIRMATIC, you must drive at raised vehicle level if snow chains have been fitted (Y page 202). i You may wish to deactivate ESP® when pulling away with snow chains fitted (Y page 73). This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). For more information on driving with the emergency spare wheel, see (Y page 390). Tyre pressure Tyre pressure specifications G WARNING Tyres with insufficient or excessive tyre pressure harbour the following hazards: Rthe tyres may burst, especially as the load and vehicle speed increase. Rthe tyres may wear excessively or unevenly which can severely impair tyre traction. Rthe handling as well as steering and braking characteristics may be severely affected. There is a risk of an accident. Z Wheels and tyres Always observe the maximum permissible speed specified for the M+S tyres you have fitted. If you fit M+S tyres that have a lower maximum permissible speed than that of the vehicle, affix a corresponding warning label in the driver's field of vision. This can be obtained at a qualified specialist workshop. Under these circumstances, you should also restrict the maximum speed of the vehicle using permanent SPEEDTRONIC so that it does not exceed the maximum permissible speed for the M+S tyres (Y page 191). When you have fitted the M+S tyres: 367 368 Tyre pressure Observe the recommended tyre pressures and check the tyre pressure of all the tyres including the spare wheel: Revery day before starting a journey the load changes Rprior to long journey Rfor changed operating conditions, e.g. offroad driving If necessary, correct the tyre pressure. Rwhen Wheels and tyres G WARNING If you fit unsuitable accessories onto tyre valves, the tyre valves may be overloaded and malfunction, which can cause tyre pressure loss. Due to their design, retrofitted tyre pressure monitors keep the tyre valve open. This can also result in tyre pressure loss. There is a risk of accident. Only screw standard valve caps or valve caps specifically provided by Mercedes-Benz for your vehicle onto the tyre valve. G WARNING If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged. Tyre pressure that is too low may result in a tyre blow-out. There is a risk of accident. RCheck the tyre for foreign objects. RCheck whether the wheel is losing air or the valve is leaking. If you are unable to rectify the damage, contact a qualified specialist workshop. H Environmental note Check the tyre pressure regularly, at least every 14 days. You will find a table of tyre pressures for various operating conditions on the inside of your vehicle's fuel filler flap. Operation with an emergency spare wheel (Y page 390). Operation with a trailer: the applicable value for the rear tyres is the maximum tyre pressure value stated in the table inside the fuel filler flap. The table inside the fuel filler flap may state tyre pressures for different load conditions. These are defined in the table as different numbers of passengers and amounts of luggage. The actual number of seats may vary; for more information, please refer to the vehicle's registration documents. If tyre sizes are not specified, the tyre pressures stated on the tyre pressure information label apply for all tyres approved for this vehicle. If a tyre size precedes a tyre pressure, the following tyre pressure information is only valid for that tyre size. Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure. On vehicles fitted with the electronic tyre pressure monitor, the tyre pressure can be checked using the on-board computer. If possible, only correct tyre pressures when the tyres are cold. The tyres are cold: Rif the vehicle has been parked with the tyres out of direct sunlight for at least three hours and Rif the vehicle has not been driven further than 1.6 km Depending on the ambient temperature, the speed at which you are driving and the load on the tyres, the tyre temperature and thus the tyre pressure changes by approximately Tyre pressure Rshorten the service life of the tyres increased tyre damage Rhave a negative effect on handling characteristics and thus driving safety (e.g. aquaplaning) Rcause i The tyre pressure values given for low loads are minimum values which offer you good ride comfort characteristics. However, you can also use the values given for higher loads. These are permissible and will not adversely affect the running of the vehicle. For speeds up to 210 km/h (does not apply to AMG vehicles): for speeds up to 210 km/h, the values given on the tyre pressure information label (fuel filler flap) may be reduced by 20 kPa (0.2 bar/3 psi) without a reduction in safety. This improves the ride comfort of your vehicle; however, fuel consumption may increase slightly. Tyre pressure loss warning system General notes While the vehicle is in motion, the tyre pressure loss warning system monitors the set tyre pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display. You can recognise the tyre pressure loss warning by the Run Flat Indicator active Restart with OK message which appears in the Serv. menu of the multifunction display. Information on the message display can be found in the "Restarting the tyre pressure loss warning system" section (Y page 369). Important safety notes The tyre pressure warning system does not warn you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure (Y page 367). The tyre pressure loss warning does not replace the need to regularly check the tyre pressures. An even loss of pressure on several tyres at the same time cannot be detected by the tyre pressure loss warning system. The tyre pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tyre is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering manoeuvres. The function of the tyre pressure loss warning system is limited or delayed if: Rsnow chains are fitted to your vehicle's tyres Rroad conditions are wintry Ryou are driving on sand or gravel Ryou adopt a very sporty driving style (cornering at high speeds or driving with high rates of acceleration) Ryou are towing a very heavy or large trailer Ryou are driving with a heavy load (in the vehicle or on the roof) Restarting the tyre pressure loss warning system Restart the tyre pressure loss warning system if you have: Rchanged the tyre pressure the wheels or tyres Rfitted new wheels or tyres X Before restarting, make sure that the tyre pressures are set properly on all four tyres Rchanged Z Wheels and tyres 10 kPa (0.1 bar/1.5 psi) per 10 †.

X Important safety notes It is the driver's responsibility to set the tyre pressure to the recommended cold tyre pressure suitable for the operating situation (Y page 367). Note that the correct tyre pressure for the current operating situation must first be taught-in to the tyre pressure monitor. If there is a substantial loss of pressure, the warning threshold for the warning message is aligned to the taught-in reference values. Restart the tyre pressure monitor after adjusting the pressures when the tyres are cold tyre (Y page 372). The current pressures are saved as new reference values. This will ensure that a warning message will only appear if the tyre pressure drops significantly. The tyre pressure monitor does not warn you of an incorrectly set tyre pressure. Observe Tyre pressure Rif the warning lamp is lit continuously, the tyre pressure on one or more tyres is significantly too low. The tyre pressure monitor is not malfunctioning. Rif the warning lamp flashes for around a minute and then remains lit constantly, the tyre pressure monitor is malfunctioning. i In addition to the warning lamp, a mes- sage appears in the multifunction display. Further information can be found at (Y page 280). If the tyre pressure monitor is malfunctioning, it may take more than ten minutes for the tyre pressure warning lamp to inform you of the malfunction by flashing for approximately one minute and then remaining lit. When the fault has been rectified, the tyre pressure warning lamp goes out after you have driven for a few minutes. The tyre pressure values indicated by the onboard computer may differ from those measured at a filling station using a pressure gauge. The tyre pressures shown by the onboard computer refer to those measured at sea level. At high altitudes, the tyre pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tyre pressures. The operation of the tyre pressure monitor can be affected by interference from radio transmitting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.

Interchanging the wheels G WARNING Interchanging the front and rear wheels may severely impair the driving characteristics if the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of accident. Interchange front and rear wheels only if the wheels and tyres are of the same dimensions. ! On vehicles fitted with a tyre pressure monitor, electronic components are located in the wheel. Tyre-fitting tools should not be applied in the area of the valve, as this could damage the electronic components. Only have tyres changed at a qualified specialist workshop. Z Wheels and tyres Radio type approval for the tyre pressure monitor 373 Wheels and tyres 374 Changing a wheel Interchanging the front and rear wheels of differing dimensions can render the general operating permit invalid. Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 374). The wear patterns on the front and rear tyres differ depending on the operating conditions. Interchange the wheels before a clear wear pattern has formed on the tyres. Front tyres typically wear more on the shoulders and the rear tyres in the centre. On vehicles that have the same size front and rear wheels, you can interchange the wheels every 5,000 to 10,000 km depending on the degree of tyre wear. Ensure that the direction of rotation is maintained. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is interchanged. Check the tyre pressure and, if necessary, restart the tyre pressure loss warning system or the tyre pressure monitor. Direction of rotation Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aquaplaning. You will only gain these benefits if the correct direction of rotation is observed. An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tyres against oil, grease, petrol and diesel. ponents damaged in this way can unexpectedly fail. There is a risk of an accident.

Wheel and tyre combinations General notes ! For safety reasons, Mercedes-Benz rec- ommends that you only use tyres and wheels which have been approved by Mercedes-Benz specifically for your vehicle. These are specially adapted to the control systems, such as ABS or ESP® and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended (tyres featuring run-flat characteristics) RMO1 = Mercedes-Benz Original (only cer- Tightening the wheel bolts (example: vehicle with emergency spare wheel) Turn the crank of the jack anti-clockwise until the vehicle is once again standing firmly on the ground. X Place the jack to one side. X Tighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: to A). The specified tightening torque is 130 Nm. X Turn the jack back to its initial position. X tain AMG tyres) Mercedes-Benz Original Extended tyres may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tyres, wheels or accessories tested and approved by Mercedes-Benz. Certain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely affected. In addition, when driving with a load, tyre dimension variations could cause the tyres to come into contact with the bodywork and axle components. This could result in damage to the tyres or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tyres, wheels or accessories other than those tested and approved. Wheel and tyre combinations Further information about wheels, tyres and approved combinations can be obtained from any qualified specialist workshop. ! Retreaded tyres are neither tested nor 379 kit can be obtained from a qualified specialist workshop. i Not all wheel/tyre combinations can be fitted at the factory in all countries. recommended by Mercedes-Benz, since previous damage cannot always be detected on retreaded tyres. As a result, Mercedes-Benz cannot guarantee vehicle safety if retreaded tyres are fitted. Do not fit used tyres if you have no information about their previous usage. ! Large wheels: the lower the section width Wheels and tyres for a certain wheel size, the lower the ride comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and the risk of damage to the wheels and tyres as a result of driving over obstacles increases. Overview of abbreviations used in the following tyre tables: RBA: both axles front axle RRA: rear axle You will find a table with recommended tyre pressures for various operating conditions on the inside of your vehicle's fuel filler flap. For further information on tyre pressure, see (Y page 367). Check tyre pressures regularly and only when the tyres are cold. Notes on the vehicle equipment – always fit the vehicle: RFA: Rwith tyres of the same size on a given axle (left/right) Rwith the same type of tyres at a given time (summer tyres, winter tyres, MOExtended tyres) i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres.

X Lift the boot floor upwards (Y page 311). You should regularly check the pressure of all your tyres, including the emergency spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 367). The value on the wheel is valid. In addition, the emergency spare wheel tyre pressure can be found under "Technical data" (Y page 394). An emergency spare wheel may also be fitted against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel. Replace the tyres after six years at the latest, regardless of wear. This also applies to the emergency spare wheel. i If you are driving with the collapsible emergency spare wheel fitted, the tyre pressure loss warning system or the tyre pressure monitor cannot function reliably. Only restart the tyre pressure loss warning system/tyre pressure monitor when the defective wheel has been replaced with a new wheel. Vehicles with tyre pressure monitor: after mounting an emergency spare wheel, the system may still display the tyre pressure of the removed wheel for a few minutes. The value displayed for the mounted emergency spare wheel is not the same as the current tyre pressure of the emergency spare wheel.

Do not use diesel to refuel vehicles with a petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, fuel can enter the fuel system. Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely. ! Only refuel using premium-grade unlea- ded petrol with at least 95 ROZ/85 MOZ, that conforms to European standard EN 228 or E DIN 51626–1 or an equivalent specification. Fuel of this specification can contain up to 10 % ethanol. Fuel that does not conform to EN 228 or E DIN 51626–1 can lead to increased wear and damage the engine and exhaust system. ! Only use the fuel recommended. Operat- ing the vehicle with other fuels can lead to engine failure. ! Do not use the following: RE85 (petrol with 85% ethanol) (100% ethanol) RM15 (petrol with 15% methanol) RM30 (petrol with 30% methanol) RM85 (petrol with 85% methanol) RM100 (100% methanol) RE100 Service products and capacities with additives containing metal Do not mix such fuels with the fuel recommended for your vehicle. Do not use additives. This can otherwise lead to engine damage. This does not include cleaning additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by MercedesBenz; see "Additives". You can obtain further information from any Mercedes-Benz Service Centre. Usually you will find information about the fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling station staff. i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle using E10 fuel. As a temporary measure, if the recommended fuel is not available, you may also use unleaded petrol with an octane rating of 91 RON/ 82 MON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration. Never refuel using fuel with a lower RON/MON. i In some countries, the available petrol may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced. Information on refuelling (Y page 178). AMG vehicles ! Only refuel using super unleaded petrol with at least 98 RON/88 MON that conforms to European standard EN 228 or an equivalent specification. You can otherwise impair engine output or damage the engine. ! Premium-grade unleaded petrol with an octane rating of 95 RON/85 MON may be used as a temporary measure if the recommended fuel is not available. This may reduce engine performance and increase fuel consumption. As much as possible, avoid driving at full throttle. ! Regular unleaded petrol with an octane rating of 91 RON/82.5 MON may also be used as a temporary measure if the recommended fuel is not available. Doing so results in noticeably higher fuel consumption, and the engine power output is noticeably reduced. Avoid driving at full throttle. If only regular unleaded petrol with an octane rating of 91 RON/82.5 MON or lower is available, you must have the vehicle adapted to this fuel at a qualified specialist workshop. i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle using E10 fuel. CLS 350 ! Only refuel using unleaded, sulphur-free unleaded petrol with at least 95 RON/ 85 MON that conforms to European standard EN 228 or an equivalent specification. You could otherwise impair engine output or damage the emission control system. i In some countries, the available petrol may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free unleaded fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced. Additives ! Operating the engine with fuel additives added later can lead to engine failure. Do not mix fuel additives with fuel. This does not include additives for the removal and prevention of residue build-up. Petrol must Z Technical data RPetrol RDiesel 401 402 Service products and capacities only be mixed with additives recommended by Mercedes-Benz. Observe the instructions for use in the product description. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre. Mercedes-Benz recommends that you use fuel brands that have additives. The quality of the fuel available in some countries may not be sufficient. Residue could build up in the injection system as a result. In this case, in consultation with a MercedesBenz Service Centre, the petrol may be mixed with the cleaning additive recommended by Mercedes-Benz. Always observe the notes and mixing ratios specified on the container. Diesel (EN 590) Fuel grade Technical data G WARNING If you mix diesel fuel with petrol, the flash point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running, components in the exhaust system may overheat unnoticed. There is a risk of fire. Never refuel with petrol. Never add petrol to diesel fuel. ! When refuelling, only use diesel fuel that conforms to the European standard EN 590 or is of equivalent quality. Fuel that does not conform to EN 590 can lead to increased wear as well as damage to the engine and exhaust system. ! Do not use the following: Rmarine diesel Rheating oil Rbio-diesel Rvegetable oil Rpetrol Rparaffin Rkerosene Do not mix such fuels with diesel fuel and do not use any special additives. This can otherwise lead to engine damage. ! Vehicles with diesel particle filters: in countries outside the EU, only use low sulphur Euro diesel with a sulphur content of under 50 ppm. Otherwise, the emission control system could be damaged. ! Vehicles without a diesel particle fil- ter: in countries where only diesel fuel with a high sulphur content is available, you will need to carry out your vehicle's oil change at shorter intervals. More information about the interval for oil change can be obtained from any qualified specialist workshop. Usually you will find information about the fuel grade on the pump. If you cannot find the label on the petrol pump, ask the filling station staff. Information on refuelling (Y page 178). Low outside temperatures In winter months, diesel fuel with an improved cold flow quality is available. In Europe, the EN 590 standard defines various climatedependent temperature categories. Malfunctions can be avoided by refuelling with diesel fuel that corresponds to the climatic specifications outlined in EN 590. At unusually low outside temperatures, it is possible that the flow characteristics of the diesel fuel could be insufficient. Accordingly, diesel fuel from warmer areas may not be suitable for operation in colder climatic conditions. i Further information on country-specific fuel properties and fuel types with low-temperature resistance can be obtained from oil companies, e.g. at filling stations. Fuel consumption information H Environmental note CO2 (carbon dioxide) is the gas which scientists believe to be principally responsible for Service products and capacities The vehicle will use more fuel than usual in the following situations: Rat very low outside temperatures Rin urban traffic Ron short journeys Rin mountainous terrain Rwhen towing a trailer i Only for certain countries: you can find the current consumption and emission values of your vehicle in the COC documents (EU CERTIFICATE OF CONFORMITY).

AdBlue® Important safety notes Comply with the important safety notes for service products when handling AdBlue® (Y page 399). AdBlue® is a water-soluble fluid for the exhaust gas aftertreatment of diesel engines. It is: Rnon-toxic Rcolourless and odourless Rnon-flammable If you open the AdBlue® tank, small amounts of ammonia vapour may be released. Ammonia vapours have a pungent odour and are particularly irritating to the skin, to mucous membranes and to the eyes. You may experience a burning sensation in your eyes, nose and throat. You may also experience coughing and watery eyes. Do not inhale any ammonia vapours that may be released. Only fill the AdBlue® tank in wellventilated areas. Low outside temperatures AdBlue® freezes at a temperature of approximately -11 †. The vehicle is delivered from the factory equipped with an AdBlue® preheating system. Winter operation can thus be guaranteed even at temperatures below -11 †. Additives ! Only use AdBlue® in accordance with ISO 22241. Do not use additives with AdBlue® and do not dilute AdBlue® with water. This may destroy the BlueTEC exhaust gas aftertreatment system. Purity ! Impurities in AdBlue® (e.g. due to other service products, cleaning agents or dust) lead to: Rincreased emission values to the catalytic converter Rengine damage Rmalfunctions in the BlueTEC® exhaust gas aftertreatment system Rdamage Z Technical data global warming (the greenhouse effect). Your vehicle's CO2 emissions are directly related to fuel consumption and therefore depend on: Refficient use of the fuel by the engine Rdriving style Rother non-technical factors, such as environmental influences, road conditions or traffic flow You can minimise your vehicle's CO2 emissions by driving carefully and having it serviced regularly. 403 404 Service products and capacities Assuring the purity of AdBlue® is particularly important with respect to avoiding malfunctions in the BlueTEC exhaust gas aftertreatment system. If AdBlue® is pumped out of the AdBlue® tank, e.g. during repair work, do not use this fluid to refill the tank. The purity of the fluid can no longer be guaranteed. Capacities Model All models Total capacity 25.5 l Engine oil Technical data General notes When handling engine oil, observe the important safety notes on service products (Y page 399). The quality of the engine oil is decisive for the function and service life of an engine. After extensive tests, Mercedes-Benz approves engine oils that correspond to the current technical standard. Therefore, only Mercedes-Benz approved engine oils may be used in Mercedes-Benz engines. Further information on tested and approved engine oils can be obtained from any Mercedes-Benz Service Centre. MercedesBenz recommends that you have the oil change carried out at a qualified specialist workshop. Mercedes-Benz approval is indicated on the oil container by the inscription "MB Approval" and the corresponding designation, e.g. MB Approval 229.51. You can call up an overview of approved engine oils on the Internet at http://bevo.mercedes-benz.com by entering the designation, e.g. 229.5.

Information about approved brake fluid can be obtained at any qualified specialist workshop or on the Internet at http://bevo.mercedes-benz.com. i Have the brake fluid regularly replaced at a qualified specialist workshop and the replacement confirmed in the Service Booklet. Brake fluid G WARNING The brake fluid continuously absorbs moisture from the air. This results in the boiling point of the brake fluid lowering. If the boiling point of the brake fluid is too low, vapour pockets may form when the brakes are subjected to a heavy load. This would impair braking efficiency. There is a risk of an accident. Have the brake fluid renewed at the prescribed intervals. Comply with the important safety notes for service products when handling brake fluid (Y page 399). The brake fluid change intervals can be found in the Service Booklet. Coolant Important safety notes G WARNING If antifreeze comes into contact with hot components in the engine compartment, it may ignite. There is a risk of fire and injury. Let the engine cool down before you top up the antifreeze. Make sure that antifreeze is not spilled next to the filler neck. Thoroughly clean the antifreeze from components before starting the engine. ! Only add coolant that has been premixed with the desired antifreeze protection. You could otherwise damage the engine. Further information on coolants can be found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop. ! Always use a suitable coolant mixture, even in countries where high temperatures prevail. Otherwise, the engine cooling system is not sufficiently protected from corrosion and overheating. i Have the coolant regularly replaced at a qualified specialist workshop and the replacement confirmed in the Service Booklet. Z Technical data Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity rating, it flows slowly; the lower the viscosity, the faster it flows. Engine oil selection is based on the respective outside temperatures and in accordance with the SAE classification (viscosity). The table shows you which SAE classifications are to be used. The low-temperature properties of engine oils can be significantly impaired during operation due to, for example, ageing or soot and fuel accretion. It is therefore strongly recommended to observe regular oil changes using an approved engine oil with the appropriate SAE classification. 406 Service products and capacities Comply with the important safety precautions for service products when handling coolant (Y page 399). The coolant is a mixture of water and antifreeze/corrosion inhibitor.
