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 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. Rdoor 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 468). 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 car- Z 25 26 Introduction ried 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 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 affect 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 anymore 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 you make any changes to the vehicle electronics, the general operating permit is rendered invalid. ! There is a risk of damage to the vehicle if: Rthe vehicle becomes stuck, e.g. on a high kerb or an unpaved road Ryou drive too fast over an obstacle, e.g. a kerb or a pothole in the road heavy object strikes the underbody or parts of the chassis Ra In situations like this, the body, the underbody, chassis parts, wheels or tyres could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, no longer withstand the strain they are designed for. If the underbody panelling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody panelling. If these materials come in contact with hot parts of the exhaust system, they can catch fire. In such situations, have the vehicle checked and repaired immediately at a qualified specialist workshop. If, upon continuing your journey, you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, consult a qualified specialist workshop. Hybrid vehicles have a combustion engine and an electric motor. The voltage supply for operating the vehicle electrically is provided by the vehicle's high-voltage electrical system. G DANGER The vehicle's high voltage electrical system is under high voltage. If you modify components in the vehicle's high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehicle's high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury. Do not touch any high-voltage components after an accident and never modify the vehicle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system checked by a qualified specialist workshop. The components of the vehicle's high-voltage electrical system are marked with yellow Introduction warning stickers. The cables of the vehicle's high-voltage electrical system are orange. Vehicles with an electric motor generate significantly less noise than vehicles with internal combustion engines. As a result, in certain situations your vehicle may not be heard by other road users. This can happen, for example, when you are parking and your vehicle is not seen by other road users. This requires you to adopt a particularly anticipatory driving style, as it is necessary to allow for the possibility that other road users may behave unpredictably. Declarations of conformity Wireless vehicle components The following information applies to all components of the vehicle and the information systems and communication devices integrated into the vehicle which receive and/or transmit radio waves: The components of this vehicle that receive and/or transmit radio waves are compliant with the basic requirements and all other relevant conditions of Directive 1999/5/EC. You can obtain further information from any Mercedes-Benz Service Centre. Electromagnetic compatibility The electromagnetic compatibility of the vehicle components has been checked and certified according to the currently valid version of Regulation ECE-R 10. Diagnostics connection The diagnostics connection is only intended for the connection of diagnostic equipment at a qualified specialist workshop. G WARNING If you connect equipment to a diagnostics connection in the vehicle, it can affect the operation of the vehicle systems. This may affect the operating safety of the vehicle. There is a risk of an accident. Do not connect any equipment to a diagnostics connection in the vehicle. 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. ! If the engine is switched off and equipment on the diagnostics connection is used, the starter battery may discharge. Connecting equipment to the diagnostics connection can lead to emissions monitoring information being reset, for example. This may lead to the vehicle failing to meet the requirements of the next emissions test during the main inspection.

Hybrid vehicles General notes Hybrid technology combines a fuel-efficient internal combustion engine with a powerful electric motor. Important safety notes Danger of electric shock G DANGER The vehicle's high voltage electrical system is under high voltage. If you modify components in the vehicle's high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehicle's high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury. Do not touch any high-voltage components after an accident and never modify the vehicle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system checked by a qualified specialist workshop. All components of the hybrid system are marked with yellow warning stickers that warn you of the danger of high voltage. The cables of the vehicle's high-voltage electrical system are orange in colour. The ignition must be switched off when carrying out general tasks, such as changing bulbs or checking the coolant level. Automatic deactivation of the hybrid system G DANGER 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. In addition, the vehicle's high-voltage electrical system may not be deactivated as intended in the event of an accident. Touching damaged components of the vehicle's highvoltage electrical system could result in an electric shock. There is an increased risk of injury, possibly even fatal. Hybrid vehicles If components of the restraint system are activated during an accident, the hybrid system is automatically deactivated. The hybrid system is not activated when the vehicle is started if: Ra short circuit is detected in the hybrid sys- tem. hybrid system electrical connection is disconnected. This ensures that you do not come into contact with high voltage. Ra Get assistance from others if necessary. The vehicle is locked automatically when the ignition is switched on and the wheels are turning. There is therefore a risk of being locked out if the vehicle is being pushed or tested on a dynamometer. X Switch the ignition off. X Shift the automatic transmission to park position P. Apply the electric parking brake (Y page 209). Secure the vehicle to prevent it from rolling away (Y page 439). X To use the high-voltage switch-off device: open the bonnet. Manual deactivation of the hybrid system The hybrid system can be deactivated manually using the high voltage switch-off device. !

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. The restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. Occupant safety Rseat belt system Rairbags Rchild restraint system Rchild seat securing system The components of the restraint system work in conjunction with each other. They can only offer protection if all vehicle occupants always: Rhave the seat belt correctly fastened (Y page 48) Rhave the seat and head restraint adjusted properly (Y page 119) As the driver, you must also make sure that the steering wheel is also adjusted properly. Observe the information on the correct driver's seat position (Y page 118). In addition, you must make sure that the airbags can inflate properly if they are deployed (Y page 51). An airbag supplements a correctly worn seat belt and, as an additional safety device, increases protection for vehicle occupants in applicable accident situations. The airbags are not deployed, for example, in the event of an accident in which sufficient protection is offered by the seat belt. In addition, only those airbags, which in the applicable accident situations offer additional protection, are deployed in the event of an accident. However, the seat belt and airbag generally do not protect against objects penetrating the vehicle from the outside. Information on how the restraint system operates can be found under "Deployment of belt tensioners and airbags" (Y page 60). See "Children in the vehicle" for further information on children travelling in the vehicle as well as on child restraint systems (Y page 63). 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. 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 functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time. The 6 restraint system warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. The components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up after the ignition is switched on Rdoes not go out after a few seconds with the engine running Rlights up again while the engine is running All vehicles, except hybrid vehicles: 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. Z Safety The restraint system includes the: 45 Safety 46 Occupant safety There is an increased risk of serious or even fatal injuries.

PASSENGER AIRBAG indicator lamp PASSENGER AIR BAG ON indicator lamp : and PASSENGER AIR BAG OFF indicator lamp ; are part of the deactivation system of the front-passenger front airbag. The indicator lamps display the status of the front-passenger front airbag. RPASSENGER AIR BAG ON : lights up: the front-passenger front airbag is enabled. If, in the case of an accident, all deployment criteria are met, the front-passenger front airbag is deployed. RPASSENGER AIR BAG OFF ; lights up: the front-passenger front airbag is disabled. It will then not be deployed in the event of an accident. Depending on the person in the frontpassenger seat, the front-passenger front airbag must either be disabled or enabled; see the following points. You must make sure of this both before and during a journey. RChildren in a rearward-facing child restraint system: the PASSENGER AIR BAG OFF indicator lamp must be lit. The front-passenger front airbag is disabled. Always observe the information on the "Automatic front-passenger front airbag deactivation system" (Y page 54) and on "Children in the vehicle" (Y page 63). RChildren in a forward-facing child restraint system: depending on the installed child restraint system, the age and size of the child the front-passenger front airbag is either disabled or enabled. Therefore, always observe the information on the "Automatic front-passenger front airbag deactivation system" (Y page 54) and on "Children in the vehicle" (Y page 63). RAll other persons: the PASSENGER AIR BAG ON indicator lamp must be lit. The front-passenger front airbag is enabled. Depending on the build of the person on the front-passenger seat, the PASSENGER AIR BAG OFF indicator lamp may light up. The front-passenger front airbag is disabled. It will then not be deployed in the event of an accident. In this case, the front-passenger seat should not be used. Always observe the information on the "Automatic front-passenger front airbag deactivation system" (Y page 54) as well Occupant safety Seat belts Introduction A correctly fastened seatbelt is the most effective means of restraining the movement of vehicle occupants in the event of a collision or if the vehicle overturns. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior or being thrown from the vehicle. Additionally, the seat belt helps to keep the vehicle occupant in the best position in relation to the airbag. The seat belt system consists of: Rseat belts tensioners for the front seat belts and the outer seat belts in the rear Rbelt force limiters for the front seat belts and the outer seat belts in the rear If the seat belt is pulled too quickly or suddenly from the belt outlet, the inertia reel will lock. 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 occupants back in the direction of the seat backrest. The belt tensioner cannot compensate for the seat position being incorrect or for a seat belt being routed or worn incorrectly. If the seat belt is also fitted with a belt force limiter and this is triggered, the force exerted 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 reduces the forces to which vehicle occupants are subjected during an accident. Rbelt ! 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 properly and are seated 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, additional 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.

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 the seat belts checked immediately at a qualified specialist workshop. Rthe Mercedes-Benz recommends that you only use seat belts which have been approved specifically for your vehicle by MercedesBenz. Any such modifications could invalidate the vehicle's general operating permit. Correct seat belt use Observe the safety notes on the seat belt (Y page 47). 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.

Information on activating and deactivating the seat-belt adjustment function can be found in the Digital Owner's Manual or in the The rear seat belt status indicator 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. If a rear seat passenger unfastens their seat belt when travelling at a speed above 25 km/h, a short warning tone also sounds. You can also cancel the rear seat belt status indicator immediately (Y page 314). Airbags Introduction The installation location of an airbag is identified by the AIRBAG symbol. An airbag supplements a correctly worn seat belt. It is not a replacement for the seat belt. The airbag offers additional protection in applicable accident situations. Not all airbags are deployed in an accident. The different airbag systems work independently of each other (Y page 60). However, no system available today can completely eliminate injuries and fatalities. It is also not possible to completely rule out a risk of injury caused by an airbag due to the speed at which the airbag must be deployed. 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 46). RAlways observe the instructions and safety notes on the automatic front-passenger front airbag deactivation system (Y page 54) and on "Children in the vehicle" (Y page 63) in addition to the child restraint system manufacturer's installation instructions. Z 51 Safety Occupant safety 52 Occupant safety 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 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. 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. Front airbags ! Do not place heavy objects on the front- passenger seat. This could cause the system to identify the seat as being occupied. In the event of an accident, the restraint systems on the front-passenger side may be triggered and have to be replaced. 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 on the front seats, the front airbags offer additional protection for the head and thorax. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you about the status of the frontpassenger front airbag (Y page 46). Front-passenger front airbag ; will only deploy if: Rthe automatic front-passenger front airbag deactivation system has detected that the front-passenger seat is occupied (Y page 54).

The driver's kneebag is triggered together with the front airbag. The driver's kneebag on the driver's seat offers additional protection for the thighs, knee and lower leg. Sidebags G WARNING Unsuitable seat covers can obstruct or prevent the deployment of the airbags integrated into the seats. Consequently, the airbags cannot protect vehicle occupants as they are designed to do. In addition, the function of the automatic front-passenger front airbag deactivation system could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the corresponding seats by Mercedes-Benz. Rarms In the event of a side impact, the sidebag is deployed on the side on which the impact occurs. vehicles with the automatic front-passenger front airbag deactivation system: the sidebag on the front-passenger side (front) deploys under the following conditions: Ran occupant is detected on the frontpassenger seat or Rthe belt tongue is engaged in the belt buckle of the front-passenger seat If the belt tongue is engaged in the belt buckle, the sidebag on the front-passenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the front-passenger seat is occupied or not. Windowbags 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. Z 53 Safety Occupant safety Safety 54 Occupant safety 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 60). Automatic front-passenger front airbag deactivation Introduction In order to recognise a child restraint system on the front-passenger seat, the automatic front-passenger front airbag deactivation system categorises the person in the frontpassenger seat. Depending on that result, the front-passenger front airbag is either enabled or disabled. If a rearward-facing child restraint system is fitted to the frontpassenger seat, the PASSENGER AIR BAG OFF indicator lamp must light up after the system self-test and remain lit. The frontpassenger front airbag is disabled. The system does not disable: Rthe sidebag windowbag Rthe seat belt tensioner Make sure that your vehicle is equipped with the automatic front-passenger front airbag deactivation system (Y page 66). If this is not the case, always fit the child restraint system on a suitable rear seat (Y page 68). If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to observe the correct positioning of the child restraint system. Never place objects under or behind the child restraint system, e.g. cushions. Fully retract the seat cushion length. The entire base of the child restraint system must always rest on the seat cushion of the front-passenger seat. The backrest of the forwards-facing child restraint system must, as far as possible, be resting on the backrest of the front-passenger seat. The Rthe child restraint system must not touch the roof or be put under strain by the head restraint. Adjust the angle of the seat backrest and the head restraint position accordingly. Only then is the correct function of the automatic frontpassenger front airbag deactivation system guaranteed. Always observe the information on suitable positioning of the child restraint system (Y page 68) in addition to the child restraint system manufacturer's installation instructions. Operation of automatic front-passenger front airbag deactivation : PASSENGER AIR BAG ON indicator lamp ; PASSENGER AIR BAG OFF indicator lamp The indicator lamps inform you whether the front-passenger front airbag is disabled or enabled. X Press the Start/Stop button once or twice, or turn the key to position 1 or 2 in the ignition lock. The system carries out a self-diagnosis. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps must light up simultaneously for approximately six seconds. The indicator lamps display the status of the front-passenger front airbag. RPASSENGER AIR BAG ON : lights up: the front-passenger front airbag is enabled. If, in the case of an accident, all deployment criteria are met, the front-passenger front airbag is deployed. RPASSENGER AIR BAG OFF ; lights up: the front-passenger front airbag is disabled. It will then not be deployed in the event of an accident. If the status of the front-passenger front airbag changes while the vehicle is in motion, an airbag display message appears in the instrument cluster (Y page 328). When the frontpassenger seat is occupied, always pay attention to the PASSENGER AIR BAG ON and PASSENGER AIR BAG OFF indicator lamps. Be aware of the status of the front-passenger front airbag both before and during the journey. If there is no child restraint system fitted to the front-passenger seat, the front-passenger must sit: Rwith the seat belt fastened correctly Rin an almost upright position with their back against the seat backrest Rwith their feet resting on the floor, if possible If the front passenger does not observe these conditions, the automatic front-passenger front airbag deactivation system may be influenced, e.g. because the front passenger: Rtransfers their weight by supporting themselves on a vehicle armrest Rsits in such a way that their weight is raised from the seat cushion The front-passenger front airbag may be disabled by mistake as a result of these or similar actions. In this case, the PASSENGER AIR BAG OFF indicator lamp lights up permanently. The front-passenger front airbag does not then deploy during an accident. into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always make sure that: Rthe classification of the person in the front- passenger seat is correct and that the frontpassenger front airbag is enabled or disabled in accordance with the person in the front-passenger seat. Rthe front-passenger seat has been moved back as far back as possible. Rthe person is seated correctly. Make sure, both before and during the journey, that the status of the front-passenger front airbag is correct. G WARNING If you secure a child on the co-driver's seat in a rearward-facing child restraint system and the PASSENGER AIR BAG ON indicator lamp lights up, the co-driver's airbag could be deployed in the event of an accident. The child could be struck by the airbag. There is an increased risk of injury, possibly even fatal. In this case, always ensure that the co-driver's airbag is disabled. The PASSENGER AIRBAG OFF indicator lamp must light up. If the PASSENGER AIR BAG OFF indicator lamp remains off and/or the PASSENGER AIR BAG ON indicator lamp lights up, do not install a rearward-facing child restraint system on the front-passenger seat. Further information can be found under "Problems with the automatic front-passenger front airbag deactivation system" (Y page 59). G WARNING If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disabled. It will not be deployed in the event of an accident and cannot perform its intended protective function. A person in the frontpassenger seat could then, for example, come Z 55 Safety Occupant safety 56 Occupant safety Safety G WARNING If you secure a child in a forward-facing child restraint system on the front-passenger seat and you position the front-passenger seat too close to the dashboard, in the event of an accident, the child could: Rcome into contact with the vehicle's interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example Rbe struck by the airbag if the PASSENGER AIR BAG ON indicator lamp is lit This poses an increased risk of injury or even fatal injury. Always move the front-passenger seat as far back as possible and fully retract the seat cushion length. Always make sure that the shoulder belt strap is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the vehicle belt outlet. If necessary, adjust the vehicle belt outlet and the front-passenger seat accordingly. Always observe the information about suitable positioning of the child restraint system in this Owner's Manual as well as the child restraint system manufacturer's installation instructions. If the automatic front-passenger front airbag deactivation system detects that: Rthe front-passenger seat is unoccupied, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the frontpassenger front airbag is disabled. Rthe front-passenger seat is occupied by a child in a rearward-facing child restraint system, the PASSENGER AIR BAG OFF indicator lamp lights up after the system selftest and remains lit. This indicates that the front-passenger front airbag is disabled. But in the case of a child in a rearwardfacing child restraint, the PASSENGER AIR BAG ON indicator lamp can light up after the system self-test and remain lit. This indicates that the front-passenger front airbag is enabled. The result of the classification is dependent on, among other factors, the child restraint system and the child's build. It is recommended that you fit the restraint system to a suitable rear seat. Rthe front-passenger seat is occupied by a child in a forward-facing child restraint system, either the PASSENGER AIR BAG ON or PASSENGER AIR BAG OFF indicator lamp lights up and remains lit after the system self-test depending on the result of the classification. The result of the classification is dependent on, among other factors, the child restraint system and the child's build. Move the front-passenger seat as far back as possible. Always observe the information in "Child restraint systems on the frontpassenger seat" (Y page 66) and in "Suitable positioning of the child restraint system" (Y page 68). Alternatively, you can fit the child restraint system to a suitable rear seat. Rthe front-passenger seat is occupied by a person with a smaller build (e.g. a teenager or small adult), either the PASSENGER AIR BAG ON or PASSENGER AIR BAG OFF indicator lamp lights up and remains lit after the system self-test depending on the result of the classification. - if the PASSENGER AIR BAG ON indicator lamp lights up, move the front-passenger seat as far back as possible. Alternatively, a person with a small build can sit on a rear seat. - if the PASSENGER AIR BAG OFF indicator lamp is lit, a person with a smaller build should not use the front-passenger seat. Rthe front-passenger seat is occupied by an adult or a person with a build corresponding to that of an adult, the PASSENGER AIR BAG ON indicator lamp lights up after the system self-test and remains lit. This indicates that the front-passenger front airbag is enabled. If children are travelling in the vehicle, be sure to observe the notes on "Children in the Vehicle" (Y page 63). If the automatic front-passenger front airbag deactivation system is malfunctioning, the red 6 restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The front-passenger front airbag is disabled in this case and does not deploy during an accident. Have the system checked as soon as possible by qualified technicians. Consult a Mercedes-Benz Service Centre. The front-passenger seat should only be repaired at a Mercedes-Benz Service Centre. If the front-passenger seat, the seat cover or the seat cushion is damaged, have the necessary repair work carried out at a MercedesBenz Service Centre. For safety reasons, Mercedes-Benz recommends that you only use a child restraint system which has been tested and approved by Mercedes-Benz in combination with the automatic front-passenger front airbag deactivation system. System self-test G DANGER If both the PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps do not light up during the system self-test, the system is malfunctioning. The frontpassenger front airbag might be triggered unintentionally or might not be triggered at all in the event of an accident with high deceleration. This poses an increased risk of injury or even fatal injury. In this case the front-passenger seat may not be used. Do not install a child restraint system on the front-passenger seat. Have the automatic front-passenger front airbag deactivation system checked and repaired immediately at a qualified specialist workshop. G WARNING If the PASSENGER AIRBAG OFF indicator lamp remains lit after the system self-test, the front-passenger front airbag is disabled. It will not be deployed in the event of an accident. In this case, the front-passenger front airbag cannot perform its intended protective function, e.g. when a person is seated in the frontpassenger seat. That person could, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the frontpassenger front airbag is enabled or disabled in accordance with the person in the front-passenger seat. Rthe person is seated properly with a correctly fastened seat belt. Rthe front-passenger seat has been moved as far back as possible.

Z Safety Problem 60 Occupant safety Deployment of belt tensioners and airbags Safety 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 you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, particularly if a seat belt tensioner was triggered or an airbag was 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 the belt tensioners are triggered or an airbag is 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. In general, the powder released is not hazardous to health but may cause shortterm breathing difficulties to persons suffering from asthma or other pulmonary conditions. Provided it is safe to do so, you should leave the vehicle immediately or open the window in order to prevent breathing difficulties. Operation During the first stage of a collision, the restraint system control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the restraint system control unit triggers the seat belt tensioners in the event of a head-on or rear collision. A seat belt tensioner can only be triggered if: Rthe ignition is switched on Rthe components of the restraint system are operational; see "Restraint system warning lamp" (Y page 45) Rthe belt tongue has engaged in the belt buckle of the respective front seat The seat belt tensioners in the rear compartment are triggered independently of the lock status of the seat belts. If the restraint system control unit detects a high severity of an accident, in certain headon collisions, additional components of the restraint system are deployed independently of each another: Rfront airbags and driver's kneebag if the system determines that deployment can offer additional protection to that provided by the seat belt On vehicles with the automatic frontpassenger front airbag deactivation system: depending on the person in the frontpassenger seat, the front-passenger front airbag is either disabled or enabled. The frontpassenger front airbag can only be deployed in an accident if the PASSENGER AIR BAG ON indicator lamp is lit. Observe the information on the PASSENGER AIR BAG indicator lamps (Y page 46). 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 Rwindowbag, injuries. The front airbag is fully deployed if the second deployment stage is activated within a few milliseconds. The activation threshold for the seat belt tensioners and airbags is determined based on the evaluation of the vehicle's rate of deceleration or acceleration at various points in the vehicle. This process is pre-emptive in nature. The triggering/deployment process should take place in good time at the start of the collision. The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by: Rthe distribution of forces during the collision Rthe collision angle Rthe deformation characteristics of the vehicle Rthe characteristics of the object with which the vehicle has collided Factors which can only be seen and measured after a collision has occurred do not play a decisive role in the deployment of an airbag, nor do they provide an indication of airbag deployment. The vehicle may be deformed significantly without an airbag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of deceleration is not high. Conversely, an airbag may be deployed even though the vehicle suffers only minor deformation. This is the case if, for example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs as a result. If the restraint system control unit detects a side impact or if the vehicle overturns, the applicable components of the restraint system are activated independently of each other depending on the apparent type of accident. If the system determines that, in this situation, triggering can offer additional protection, the seat belt tensioners are also triggered. RSidebags on the side on which an impact occurs, independent from the seat belt tensioner and seat belt usage Vehicles with the automatic frontpassenger front airbag deactivation system: the sidebag on the front-passenger side (front) deploys under the following conditions: - an occupant is detected on the frontpassenger seat or - the belt tongue is engaged in the belt buckle of the front-passenger seat RWindowbag on the side on which an impact occurs, independent of seat belt usage and regardless of whether the front-passenger seat is occupied RWindowbags on the driver's and frontpassenger side in certain situations if the vehicle overturns and if the system determines that deployment can offer additional protection to that provided by the seat belt i Not all airbags are deployed in an acci- dent.

PRE-SAFE® PLUS (anticipatory occupant protection PLUS) Introduction PRE-SAFE® PLUS is only available in vehicles with the Driving Assistance package. Using the radar sensor system, PRE-SAFE® PLUS is able to detect that a head-on or rearend collision is imminent. In certain hazardous situations, PRE-SAFE® PLUS takes preemptive measures to protect the vehicle occupants. Important safety notes The intervention of PRE-SAFE® PLUS cannot prevent an imminent collision. The driver is not warned when PRE-SAFE® PLUS intervenes. PRE-SAFE® PLUS does not intervene: Rif the vehicle is reversing the vehicle is towing a trailer and there is a risk of a rear-end collision PRE-SAFE® PLUS does not perform braking actions while the vehicle is in motion or when Parking Guidance is active. Rwhen Children in the vehicle PRE-SAFE® PLUS intervenes in certain situations if the radar sensor system detects an imminent head-on or rear-end collision. PRE-SAFE® PLUS takes the following measures depending on the hazardous situation detected: RIf the radar sensor system detects that a head-on collision is imminent, the seat belts are pre-tensioned. RIf the radar sensor system detects that a rear-end collision is imminent: - the rear hazard warning lamps are activated and flash at a higher frequency. - the brake pressure is increased if the driver applies the brakes when the vehicle is stationary. - the seat belts are pre-tensioned. The PRE-SAFE® PLUS braking application is cancelled: Rif the accelerator pedal is depressed when a gear is engaged Rif the risk of a collision passes or is no longer detected Rif DISTRONIC PLUS indicates an intention to pull away If the hazardous situation passes without resulting in an accident, the original settings are restored. Automatic measures after an accident Immediately after an accident, the following measures are implemented, depending on the type and severity of the impact: Rthe hazard warning lamps are activated emergency lighting is activated Rthe vehicle doors are unlocked Rthe front side windows are lowered Rvehicles with a memory function: the electrically adjustable steering wheel is raised Rthe engine is switched off Rthe Rvehicles with the Mercedes-Benz emergency call system: automatic emergency call Rvehicles with the hybrid drive system: the hybrid system is deactivated Children in the vehicle Important safety notes Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Children are generally better protected there. If a child younger than 12 years old and under 1.50 m in height is travelling in the vehicle: Ralways secure the child in a child restraint system suitable for Mercedes-Benz vehicles. The child restraint system must be appropriate to the age, weight and size of the child Rbe sure to observe the instructions and safety notes in this section in addition to the child restraint system manufacturer's installation instructions Ralways pay attention to the instructions and safety notes on the automatic frontpassenger front airbag deactivation system (Y page 54) G WARNING If you leave children unattended in the vehicle, they may be able to set the vehicle in motion if, for example, they: Rrelease the parking brake Rshift the automatic transmission out of park position P or shift manual transmission into neutral Rstart the engine In addition, they may operate vehicle equipment and become trapped. There is a risk of an accident and injury. Z Safety Function 63 64 Children in the vehicle Safety When leaving the vehicle, always take the key with you and lock the vehicle.

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: (Anti-lock Braking System) (Y page 74) RBAS (Brake Assist System) (Y page 75) RBAS PLUS with Cross-Traffic Assist (Brake Assist System PLUS with Cross-Traffic Assist) (Y page 75) RCOLLISION PREVENTION ASSIST PLUS (distance warning function and adaptive Brake Assist) (Y page 77) RAdaptive brake lamps (Y page 80) RESP® (Electronic Stability Program) (Y page 80) REBD (electronic brake force distribution) (Y page 82) RADAPTIVE BRAKE (Y page 82) RPRE-SAFE® Brake (Y page 82) RSTEER CONTROL (Y page 85) 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. 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 428). 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. RABS 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 ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. Driving safety systems Important safety notes Important safety notes i Observe the "Important safety notes" sec- i Observe the "Important safety notes" sec- 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. 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. If ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 355) and display messages which may be shown in the instrument cluster (Y page 315). 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. Braking 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, and functions 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. tion (Y page 74). 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 PLUS) with Cross-Traffic Assist General notes i Observe the "Important safety notes" section (Y page 74). BAS PLUS is only available on vehicles with the Driving Assistance package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a camera system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an extended period of time Rthat cross the path of your vehicle In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians using typical characteristics such as the body contours and posture of a person standing upright. If the radar sensor system or the camera system is malfunctioning, BAS PLUS functions are restricted or no longer available. The Z Safety tion (Y page 74). 75 76 Driving safety systems brake system is still available with complete brake boosting effect and BAS. Safety i Observe the restrictions described in the "Important safety notes" section (Y page 76). BAS PLUS can help you to minimise the risk of a collision with a vehicle or a pedestrian and reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking. 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 small people, e.g. children animals Rto oncoming vehicles Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto In the event of snowfall or heavy rain, 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 Rinterference Ra narrow vehicle travelling in front, e.g. a motorcycle Ra vehicle travelling in front on a different line Rvehicles quickly moving into the radar sensor system detection range Detection by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is covered Rglare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif: - pedestrians move quickly, e.g. into the path of the vehicle - the camera system no longer detects a pedestrian as a person due to special clothing or other objects - a pedestrian is concealed by other objects - the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the 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. Following damage to the windscreen, have the configuration and operation of the camera system checked at a qualified specialist workshop. Function To avoid a collision, BAS PLUS calculates the brake force necessary if: 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. RBAS 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 with vehicles in front within a speed range between 7 km/h and 250 km/h. At speeds of up to approximately 70 km/h, BAS PLUS can react to: Rstationary objects in the path of your vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robstacles crossing your path, which move in the detection range of the sensors and are recognised by them 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 again if: Ryou release the brake pedal is no longer a risk of collision Rno obstacle is detected in front of your vehicle Ryou depress the accelerator pedal Ryou activate kickdown Rthere COLLISION PREVENTION ASSIST PLUS General notes COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autonomous emergency braking function and adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimise the risk of a collision with the vehicle in front or reduce the effects of such a collision. If COLLISION PREVENTION ASSIST PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. If you do not react to the visual and audible collision warning, autonomous braking can be initiated in critical situations. If you apply the brake yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake Assist assists you. Important safety notes In particular, the detection of obstacles can be impaired in the case of: Rdirt on the sensors or obscured sensors or heavy rain Rinterference 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 Rnew vehicles or after a service on the COLLISION PREVENTION ASSIST PLUS system Please observe the information in the section on running-in the vehicle (Y page 180). Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at slow speeds where there is no visible damage to the front of the vehicle. Rsnow Distance warning function Important safety notes i Observe the "Important safety notes" section for driving safety systems (Y page 74). Z 77 Safety Driving safety systems 78 Driving safety systems G WARNING The distance warning function does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Safety Rto G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. In such cases, the distance warning function may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay careful attention to the traffic situation; do not rely on the distance warning function alone. Rnot Function X To activate/deactivate: activate or deactivate the distance warning function in the on-board computer (Y page 308). If the distance warning function is deactivated, the æ symbol appears in the assistance graphics display. The distance warning function can help you to minimise the risk of a collision with the vehicle in front or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically. The distance warning function issues a warning at speeds: Rof approximately 30 km/h or more, if, over several seconds, the distance maintained to the vehicle travelling in front is insuffi- cient. The · distance warning lamp then lights up in the instrument cluster. Rof approximately 7 km/h or more, if you rapidly approach a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action provided it is safe to do so. Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the system to display a warning. With the help of the radar sensor system, the distance warning function can detect obstacles that are in the path of your vehicle for an extended period of time. Up to a speed of approximately 70 km/h, the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles. If you approach an obstacle and the distance warning function detects a risk of a collision, the system will alert you both visually and acoustically. Autonomous braking function If the driver does not react to the distance warning signal in a critical situation, COLLISION PREVENTION ASSIST PLUS can assist with the autonomous braking function. The autonomous braking function: Rgives the driver more time to react to critical driving situations Rcan help the driver to avoid an accident or Rreduces the effects of an accident Vehicles without DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R7 - 105 km/h for moving objects R7 - 50 km/h for stationary objects Vehicles with DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R7 - 200 km/h for moving objects - 50 km/h for stationary objects If the autonomous braking function demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. R7 Adaptive Brake Assist i Observe the "Important safety notes" section (Y page 74). Adaptive Brake Assist provides braking assistance in hazardous situations at speeds above 7 km/h. It uses radar sensor technology to assess the traffic situation. G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In such cases, Adaptive Brake Assist can: Rintervene unnecessarily intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. Rnot G WARNING Adaptive Brake Assist does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering As a result, the Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto tions may also cause Brake Assist to intervene. If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. With the help of adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of collision with the vehicle in front, it calculates the braking force necessary to avoid a collision. If you apply the brakes forcefully, adaptive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal is no longer any danger of a collision Rno obstacle is detected in front of your vehicle Adaptive Brake Assist is then deactivated. If adaptive Brake Assist demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. Up to a speed of approximately 250 km/h, adaptive Brake Assist is capable of reacting to moving objects that have already been detected as such at least once over the period of observation. Up to a speed of approximately 70 km/h adaptive Brake Assist reacts to stationary obstacles. Rthere Due to the nature of the system, particularly complicated but non-critical driving condiZ 79 Safety Driving safety systems 80 Driving safety systems Adaptive brake lamps The adaptive brake lights warn following traffic in an emergency braking situation: Safety Rby flashing brake lamps activating the hazard warning lamps 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 137). Rby ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes" section (Y page 74). 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) i Observe the "Important safety notes" section (Y page 74). ETS traction control is part of ESP®. On vehicles with 4MATIC, 4ETS is a component 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 i Observe the "Important safety notes" section (Y page 74). 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. ! If you test the parking brake using a brake dynamometer, switch the ignition off. Application of the brakes by ESP® may otherwise destroy the brake system. When towing your vehicle with the rear axle raised, observe the notes on ESP® (Y page 422). ESP® is deactivated if the å warning lamp in the instrument cluster lights up and: Rthe vehicle is moving ECO start/stop function is activated If the ÷ warning lamp lights up continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 357) and display messages which may be shown in the instrument cluster (Y page 315). Only use wheels with the recommended tyre sizes. Only then will ESP® function properly. Rthe Driving safety systems 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. 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® Important safety notes i Observe the "Important safety notes" section (Y page 74). You can select between the following states 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. It may be best to deactivate ESP® in the following situations: Rwhen using snow chains deep snow Ron sand or gravel Activate ESP® as soon as the situations described above no longer apply. ESP® will otherwise not be able to stabilise the vehicle if the vehicle starts to skid or a wheel starts to spin. Rin Deactivating/activating ESP® You can deactivate or activate ESP® via the on-board computer. X To deactivate: (Y page 307). The å ESP® OFF warning lamp in the instrument cluster lights up. X To activate: (Y page 307). The å ESP® OFF warning lamp in the instrument cluster goes out. Characteristics when ESP® is deactivated If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster does not flash. In such situations, ESP® will not stabilise the vehicle. If you deactivate ESP®: RESP® no longer improves driving stability driven wheels can spin The spinning of the wheels results in a cutting action for better traction on loose surfaces. Rtraction control is still activated RPRE-SAFE® is no longer available; nor is it activated if you brake firmly with assistance from ESP® RPRE-SAFE® Brake is no longer available; it is also not activated if you brake firmly with assistance from ESP® RESP® still provides support when you brake firmly. Rthe Z Safety Characteristics of ESP® 81 82 Driving safety systems Safety ESP® trailer stabilisation General notes If your vehicle/trailer combination begins to lurch, ESP® assists you in this situation. 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 approximately 65 km/h. ESP® trailer stabilisation does not work if ESP® is deactivated or disabled because of a malfunction. Important safety notes Crosswind Assist does not work if ESP® is deactivated or disabled because of a malfunction. EBD (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" section (Y page 74). G WARNING If EBD is malfunctioning, the rear wheels can 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 355) as well as display messages (Y page 318). Crosswind Assist General notes Strong crosswind gusts can impair the roadholding of your vehicle when driving straight ahead. The crosswind driving assistance function integrated in ESP® noticeably reduces these impairments. Depending on the direction and intensity of the side wind, ESP® is activated automatically. ESP intervenes with stabilising braking to assist you in keeping the vehicle in the lane. Crosswind Assist is active at vehicle speeds above 80 km/h when driving straight ahead or cornering gently. ADAPTIVE BRAKE 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 232) and hill start assist (Y page 185). PRE-SAFE® Brake General notes i Pay attention to the important safety notes in the "Driving safety systems" section (Y page 74). Driving safety systems Important safety notes 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. 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. In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. 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 a speed of up to approximately 70 km/h, PRE-SAFE® Brake can also detect: Rstationary objects in the path of your vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle G WARNING G WARNING PRE-SAFE® Brake will initially brake your vehi- PRE-SAFE® Brake does not react: cle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you brake yourself. Even after subsequent full application of the brakes a collision cannot always be avoided, particularly when approaching at too high a speed. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action, provided it is safe to do so. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. Rto small people, e.g. children Rto animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering 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. Z Safety PRE‑SAFE® Brake is only available for vehicles with the Driving Assistance package. For PRE-SAFE® Brake to assist you when driving, the radar sensor system and the camera system must be switched on and operational. With the help of the radar sensor system and the camera system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. In addition, pedestrians in the path of your vehicle can be detected. PRE-SAFE® Brake detects pedestrians using typical characteristics such as the body contours and posture of a person standing upright. Observe the restrictions described in the "Important safety notes" section“ (Y page 83). PRE-SAFE® Brake can help you to minimise the risk of a collision with a vehicle ahead or a pedestrian, and reduce the effects of such a collision. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. 83 84 Driving safety systems Detection by the radar sensor system is also impaired in the event of: Safety Rdirt on the sensors or obscured sensors Rinterference 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 Detection by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is covered Rglare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif: - pedestrians move quickly, e.g. into the path of the vehicle - the camera system no longer detects a pedestrian as a person due to special clothing or other objects - a pedestrian is concealed by other objects - the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the 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. Following damage to the windscreen, have the configuration and operation of the camera system checked at a qualified specialist workshop. Function X To activate/deactivate: activate or deactivate PRE-SAFE® Brake in the on-board computer (Y page 309). 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 higher, you very quickly approach a vehicle in front or a pedestrian. An intermittent warning tone will then sound and the · distance warning lamp lights up in the instrument cluster. X Brake immediately to defuse the situation. or X Take evasive action provided it is safe to do so. If there is an increased risk of collision, preventive passenger protection measures (PRESAFE®) are activated. If the risk of collision with the vehicle in front remains and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic emergency braking, up to the point of full brake application. Automatic emergency braking is not performed until immediately prior to an imminent accident.

Exterior lighting General notes For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations. Driving abroad General notes 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 as soon as possible after crossing the border (only vehicles with Intelligent Light System). This prevents oncoming traffic from being dazzled. Symmetrical lights do not illuminate as large an area of the edge of the carriageway. ments are fulfilled without switching the headlamps to symmetrical dipped beam. Vehicles with Intelligent Light System Before crossing the border, set the headlamps to symmetrical dipped beam and after returning back to asymmetrical dipped beam via the "Dipped-beam headlamps for driving on the right/left" function in the on-board computer (Y page 311). If the headlamps are converted to symmetrical dipped beam, the "motorway mode" and "extended range foglamps" functions are not available.

Rthe Z Lights and windscreen wipers X 138 Exterior lighting Intelligent Light System Cornering light function Lights and windscreen wipers 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" function using the on-board computer (Y page 311). Active light function 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 The cornering lamp may remain lit for a short time, but is automatically switched off after no more than three minutes. 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 you are driving. This allows you to recognise pedestrians, cyclists and animals. Active: when the lights are switched on 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 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 Plus General notes With Adaptive Highbeam Assist Plus, you can automatically switch between dipped-beam, partial main-beam and main-beam headlamps. Partial main-beam illumination is a form of illumination whereby the main beam is directed past other road users. Other road users are kept out of the main-beam. This prevents glare. If there is a vehicle in front, for example, the main-beam headlamps illuminate the areas to its right and left, and the vehicle in front is illuminated by the dipped-beam headlamps. 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. If the main-beam or partial main-beam headlamps are causing too much reflection from traffic signs, the lights are automatically dimmed and glare for the driver caused by the reflections is thus avoided. The system's optical sensor is located behind the windscreen near the overhead control panel. Important safety notes G WARNING Adaptive Highbeam Assist Plus 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 Plus may not recognise road users who do have lights, or may recognise them too late. In this, or in similar situations, the automatic main-beam headlamps will not be deactivated or will be activated despite the presence of other road users. There is a risk of an accident. Always carefully observe the traffic conditions and switch off the main-beam headlamps in good time.

To prevent the windows from misting up: Rswitch Rswitch briefly Rswitch off climate control only briefly on air-recirculation mode only on the cooling with air dehumidification function Rswitch on the "demist windscreen" function briefly, if required Climate control regulates the temperature and air humidity in the vehicle interior. The interior filter cleans the air, thus improving the interior climate. For vehicles without hybrid drive, the "Cooling with air dehumidification" function is available when the engine is running. For hybrid vehicles, the cooling with air dehumidification function is also available via the electric refrigerant compressor when the engine is not running. Optimum climate control is only achieved with the side windows and roof closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 166). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 107). This will speed up the cooling process and the desired 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. i It is possible that the blower may be activated automatically 60 minutes after the key has been removed depending on various factors, e.g. the outside temperature.

Auxiliary heating Important safety notes 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: Rhot parts of the exhaust system exhaust gas itself There is a risk of fire. Rthe When the auxiliary heating is switched on, make sure that: Rno flammable materials come into contact with hot vehicle components Rthe exhaust gas can escape from the exhaust pipe unhindered Rthe exhaust gas does not come into contact with flammable materials. The auxiliary heating is fitted under the front wing on the right-hand side of the vehicle. The emissions outlet is found behind the front wheel on the right hand side of the vehicle. ! Operating the auxiliary heating/ventila- tion draws on the vehicle battery. After you have heated or ventilated the vehicle a maximum of two times, drive for a longer distance. 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.

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 1,500 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 1,500 km. RAvoid overstraining the vehicle during this period, e.g. driving at full throttle. RWhen changing gears manually, change up in good time, before the rev counter needle reaches Ô of the way to the red area of the rev counter. RDo not shift down a gear manually in order to brake. RVehicles with automatic transmission: try to avoid depressing the accelerator pedal beyond the point of resistance (kickdown). After 1,500 km, you may gradually accelerate the vehicle to full road and engine speeds. You should also observe these notes on running-in if the engine or parts of the drive train on your vehicle have been replaced. Always observe the applicable speed limit. 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. G WARNING 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 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.

AdBlue® (BlueTEC vehicles only) Important notes on use To function properly, BlueTEC exhaust gas aftertreatment must be operated with the reducing agent AdBlue®. Topping up AdBlue® is part of the maintenance work. When the supply of AdBlue® is down to approximately 3.0 litres, the Refill AdBlue See Owner's Manual message is shown in the multifunction display. When the AdBlue® supply drops to a minimum, the Refill AdBlue No start in X km message is shown in the multifunction display. If you drive the vehicle faster than 15 km/h, the Refill AdBlue See Owner's Manual message goes out after approximately one minute. If the Refill AdBlue No start in X km message is shown in the multifunction display, you can still drive the vehicle over the distance shown. If the AdBlue® is not topped up, you will subsequently be unable to start the engine. If the Refill AdBlue Start not possible message appears in the multifunction display and the engine does not start, you must top up AdBlue®. Add at least 3.5 l of AdBlue®. Switch on the ignition for at least 60 seconds. X Start the engine. X X i You can also have the AdBlue® tank refilled at a qualified specialist workshop. Before driving your vehicle outside Europe, have the AdBlue® supply checked at a qualified specialist workshop. Further information about BlueTEC exhaust gas aftertreatment and about AdBlue® can be obtained from any Mercedes-Benz Service Centre. Important notes on the refilling procedure 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, Refuelling rinse AdBlue® off your skin with soap and water. Rif AdBlue® comes into contact with your eyes, immediately rinse them thoroughly with clean water. Seek medical attention immediately. Rif AdBlue® is swallowed, immediately rinse your mouth out thoroughly. Drink plenty of water. Seek medical attention immediately. Rchange immediately out of clothing that has come into contact with AdBlue®. Rimmediately ! Only use AdBlue® in accordance with ISO 22241. Do not mix any additives with AdBlue®, and do not dilute AdBlue® with water. This may destroy the BlueTEC exhaust gas aftertreatment system. ! In order to fill the AdBlue® tank, the vehicle must be parked on a level surface. The AdBlue® tank can only be filled as intended with the vehicle parked on a level surface. Fluctuations in capacity will thus be avoided. Filling a vehicle standing on an uneven surface is not permitted. There is a danger of overfilling, which can cause damage to BlueTEC exhaust gas aftertreatment components. ! Surfaces which have come into contact with AdBlue® while refilling should be rinsed immediately with water, or remove AdBlue® with a moist cloth and cold water. If AdBlue® has already crystallised, use a sponge and cold water to clean the area. AdBlue® residue crystallises after a certain amount of time and soils the affected surfaces. ! AdBlue® is not a fuel additive and must not be added to the fuel tank. If AdBlue® is added to the fuel tank, this can lead to engine damage. Have the AdBlue® tank refilled at a qualified specialist workshop. However, you can also top up the AdBlue® tank: a filling station with an AdBlue® filling pump Rwith AdBlue® refill bottles Rwith an AdBlue® refill canister When the pump nozzle switches off automatically during filling at a filling pump, the AdBlue® tank has been completely filled. Do not fill the AdBlue® tank any further. AdBlue® may leak out.

Electric parking brake General notes G WARNING If you leave children unattended in the vehicle, they may be able to set the vehicle in motion if, for example, they: Rrelease the parking brake Rshift the automatic transmission out of park position P or shift manual transmission into neutral Rstart the engine In addition, they may operate vehicle equipment and become trapped. There is a risk of an accident and injury. When leaving the vehicle, always take the key with you and lock the vehicle. Never leave children unattended in the vehicle. The function of the electric parking brake is dependent on the on-board voltage. If the onboard voltage is low or if there is a malfunction in the system, it may not be possible to apply the released parking brake. If this is the case, only park the vehicle on level ground and secure it to prevent it from rolling away. X Vehicles with automatic transmission: shift the automatic transmission to position P. X Vehicles with manual transmission: engage first gear. X It may not be possible to release an applied parking brake if the on-board voltage is low or if there is a malfunction in the system. Contact a qualified specialist workshop. The electric parking brake carries out a function check at regular intervals when the engine is switched off. Noises that occur are normal.

Important safety 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. Drive sensibly – save fuel Observe the following tips to save fuel: The tyres should always be inflated to the recommended tyre pressure. X Remove unnecessary loads. X Remove roof racks when they are not needed. X Warm up the engine at low engine speeds. X Avoid frequent acceleration or braking. X Have all maintenance work carried out as indicated by the service intervals in the Service Booklet or by the service interval display. X Fuel consumption also increases when driving in cold weather, in stop-start traffic, on short journeys and in hilly terrain. ECO display The ECO display shows you how economical your driving style is. 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. Z Driving and parking The vehicle is braked as long as you keep handle : of the electric parking brake depressed. The longer the electric parking brake handle : is depressed, the greater the braking force. During braking: 211 212 Driving tips The ECO display consists of three sections, with an inner and outer area. The sections correspond to the following three categories: Driving and parking : Acceleration (evaluation of all acceleration processes): Rthe : ; = ? Acceleration Coasting Constant Additional range achieved outer area fills up and the inner area lights up green: moderate acceleration, especially at higher speeds Rthe outer area empties and the inner area is grey: sporty acceleration ; Range ? is shown under Bonus fr. start and represents the additional range achieved since the beginning of the journey as a result of an adapted driving style. If the fuel level has dropped into the reserve range, the Reserve fuel message is shown in the multifunction display instead of range ?. In addition, the 8 warning lamp in the instrument cluster lights up (Y page 360). Coasting (evaluation of all deceleration processes): Rthe outer area fills up and the inner area lights up green: anticipatory driving, keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes. Rthe outer area empties and the inner area is grey: frequent heavy braking = Constant (continuous evaluation over the entire journey): Rthe outer area fills up and the inner area lights up green: constant speed and avoidance of unnecessary acceleration and deceleration Rthe outer area empties and the inner area is grey: fluctuations in speed The three inner areas display the current driving style and light up green as a result of a particularly economical driving style. Depending on the driving situation, up to two areas may light up simultaneously. At the beginning of the journey, the three outer areas are empty and fill up as a result of economical driving. A higher level indicates a more economical driving style. If the three outer areas are completely filled at the same Driving tips Rload Rtyre pressure Rcold start Rchoice of route Rthe use of electrical consumers These factors are not included in the ECO display. An economical driving style involves driving at a moderate engine speed. To achieve a higher value in the categories "acceleration" and "smooth driving": Robserve the gearshift recommendation the vehicle in drive program E (vehicles with the AGILITY SELECT switch) On long journeys at a constant speed, e.g. on the motorway, only the outer area for "constant" will change. The ECO display summarises the driving style from the start of the journey to its completion. Therefore, there are more marked changes in the outer areas at the start of a journey. During a prolonged driving time, these changes are smaller. For more marked changes, perform a manual rest (Y page 299). Further information on the ECO display (Y page 298). Rdrive 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 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. This also applies if cruise control, DISTRONIC PLUS or SPEEDTRONIC are activated. 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. 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 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 heavy demands are made on the brakes, do not park the vehicle immediately. Drive on for a short while. This allows the airflow to cool the brakes more quickly. Z Driving and parking time, the driver has adopted the most economical driving style for the selected settings and prevailing conditions. The ECO display border lights up. The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under Bonus fr. start does not indicate a fixed consumption reduction. In addition to driving style, the actual consumption is affected by other factors, such as: 213 Driving and parking 214 Driving tips 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 a layer of salt forming, 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 discs and 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 only fitting the following brake discs and brake pads/linings: Rbrake discs that have been approved by Mercedes-Benz Rbrake pads/linings that have been approved by Mercedes-Benz or that are of an equivalent standard of quality Other brake discs or brake pads/linings can compromise the safety of your vehicle. Always replace all brake discs and brake pads/linings on an axle at the same time. Always fit new brake pads/linings when replacing brake discs. The vehicle is equipped with lightweight brake discs to which the wheel assembly with rim and threaded connection is matched. The use of brake discs other than those approved by Mercedes-Benz may alter track width and is subject to approval, if applicable. Shock-type loads when handling the brake discs, such as when changing wheels, can lead to a reduction in comfort when driving with lightweight brake discs. Avoid shocktype loads on the lightweight brake discs, particularly on the brake plate. 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 Ravoid your speed tyre ruts Driving tips sudden steering movements carefully 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 water level, in the case of still water, may not exceed a maximum point of the lower edge of the vehicle body 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. Do not use cruise control or DISTRONIC PLUS. If the vehicle threatens to skid or cannot be stopped when moving at low speed: Vehicles with manual transmission: shift to neutral. X Vehicles with automatic transmission: shift 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 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 lever Cruise control General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. 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. 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.

DISTRONIC PLUS General notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. Vehicles are detected with the aid of the radar sensor system. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. Without your intervention, DISTRONIC PLUS cannot prevent a collision. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately to increase the distance to the vehicle driving in front, or take evasive action, provided it is safe to do so. DISTRONIC PLUS operates in the 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. stopped or parked vehicles Roncoming 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. G WARNING DISTRONIC PLUS cannot always clearly recognise other road users and complex traffic conditions. In such cases, DISTRONIC PLUS may: Rgive an unnecessary warning and then brake the vehicle Rneither give a warning nor intervene Raccelerate or brake unexpectedly There is a risk of an accident. Continue to drive carefully and be prepared to brake, particularly if DISTRONIC PLUS warns you. G WARNING DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration. If this deceleration is not sufficient, DISTRONIC PLUS alerts you with a visual and acoustic warning. There is a risk of an accident. Apply the brakes yourself in these situations and try to take evasive action. ! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automatically in certain situations.

Otherwise, it sets the vehicle cruise speed to the previously stored value. X Driving with DISTRONIC PLUS Pulling away and driving If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained. If DISTRONIC PLUS detects a faster-moving vehicle in front, it increases the driving speed. However, the vehicle is only accelerated up to the speed you have stored. Selecting the drive program DISTRONIC PLUS supports a sporty driving style when you have selected the S or S+ drive program (Y page 197). Acceleration behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have selected the C or E drive program, the vehicle accelerates more gently. This setting is recommended in stop-and-start traffic. Changing lanes If you change to the overtaking lane, DISTRONIC PLUS supports you if: Ryou are driving faster than 70 km/h switch on the respective turn signal RDISTRONIC PLUS does not detect a danger of collision If these conditions are met, your vehicle is accelerated.

The 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 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. The system takes into account the fact that overtaking on the right is not permitted on motorways or high-speed major roads at speeds above 80 km/h. The driving speed is adjusted to the speed of the queue of vehicles in the adjacent lane to the left. Rapproach i Prevention of overtaking on the right applies to countries where traffic drives on the right. In countries where traffic drives on the left, overtaking on the left is prevented accordingly. 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. For further information on deactivating DISTRONIC PLUS (Y page 228). 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. After a short period, the vehicle is secured by the electric parking brake, thus relieving the service brake. Depending on the specified minimum distance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. The electric parking brake secures the vehicle automatically if DISTRONIC PLUS is activated and: Rthe seat belt is unfastened and the driver's door is open Rthe engine is switched off, unless it is auto- matically switched off by the ECO start/ stop function Driving systems system fault occurs power supply is insufficient If a malfunction occurs, then the transmission may also be shifted into position P automatically. Rthe Setting a speed Setting the specified minimum distance You can set the specified minimum distance for DISTRONIC PLUS by varying the time span between one and two seconds. With this function, you can set the minimum distance that DISTRONIC PLUS keeps to the vehicle in front, dependent on vehicle speed. You can see this distance in the multifunction display (Y page 228). i Make sure that you maintain the mini- mum distance to the vehicle in front as required by law.

The distance to the vehicle in front will be too short. Driving and parking Other vehicles changing lane DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Crossing vehicles DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot General notes DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the carriageway because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles DISTRONIC PLUS with Steering Assist and Stop&Go Pilot aids you in keeping the vehicle in the centre of the driving lane by means of moderate steering interventions in a speed range from 0 - 200 km/h. It monitors the area in front of your vehicle by means of camera system : at the top of the windscreen. Driving systems Important safety notes If you fail to adapt your driving style, DISTRONIC PLUS with Steering Assist and Stop&Go Pilot can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot 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. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot does not detect road and traffic conditions and does not detect all road users. If you are following a vehicle which is driving towards the edge of the carriageway, your vehicle could come into contact with the kerb or other road boundaries. In the case of deviations in road markings, beware of other road users, e.g. cyclists, that are directly next to your vehicle. Obstacles such as traffic pylons on the lane or projecting out into the lane are not detected. An inappropriate steering intervention, e.g. after intentionally driving over a lane marking, can be corrected at any time if you steer slightly in the opposite direction. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. 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 The system is switched to passive and no longer assists you by performing steering interventions if: Ryou actively change lane switch on the turn signal Ryou take your hands off the steering wheel or do not steer for a prolonged period of time Ryou i After you have finished changing lanes, Steering Assist and Stop&Go Pilot are automatically active again. Steering Assist and Stop&Go Pilot cannot provide assistance: Ron very sharp corners towing a trailer Ra loss of tyre pressure or a defective tyre has been detected and displayed Rwhen Z Driving and parking At speeds of more than 60 km/h Steering Assist focuses on clear lane markings (left and right). In a speed range from 0 - 60 km/h Stop&Go Pilot focuses on the vehicle in front, taking into account lane markings, e.g. when following vehicles in a traffic jam. If these conditions are not present, Steering Assist and Stop&Go Pilot cannot provide assistance. DISTRONIC PLUS must be active in order for the function to be available. 231 Driving systems Driving and parking 232 Also observe the important safety notes for DISTRONIC PLUS (Y page 222). The steering interventions are carried out with a limited steering moment. The system requires the driver to keep his hands on the steering wheel and to steer himself. If you do not steer yourself or if you take your hands off the steering wheel for a prolonged period of time, the system will first alert you with a visual warning. A steering wheel symbol appears in the multifunction display. If you have still not started to steer and have not taken hold of the steering wheel after five seconds at the latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Assist and Stop&Go Pilot switch to passive mode. DISTRONIC PLUS remains active.

When driving at speeds below 80 km/h, the vehicle is raised again. 4MATIC (permanent all-wheel drive) 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. If you fail to adapt your driving style, 4MATIC can neither reduce the risk of an accident nor Z 235 Driving and parking Driving systems Driving and parking 236 Driving systems 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 you use winter tyres (M+S tyres), with snow chains if necessary. PARKTRONIC Important safety notes PARKTRONIC is an electronic parking aid with ultrasonic sensors. It monitors the area around your vehicle using six sensors in the front bumper and six sensors in the rear bumper. PARKTRONIC indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a 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. ! 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. ! Fold in the ball coupling if the trailer tow hitch is not required. PARKTRONIC measures the minimum detection range to an obstacle from the bumper, not the ball coupling. PARKTRONIC is activated automatically if you: Rswitch on the ignition the transmission to position D, R or N PARKTRONIC is deactivated at speeds above 18 km/h. It is reactivated at lower speeds. PARKTRONIC is deactivated for the rear area when you establish an electrical connection between your vehicle and a trailer.

Active Parking Assist General notes Active Parking Assist is an electronic parking aid with ultrasound. It measures the road on both sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering intervention and brake application can assist you during parking and when exiting a parking space. You may also use PARKTRONIC (Y page 236). 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. For vehicles with the trailer tow hitch folded out, the minimum length for parking spaces is slightly longer. If you have attached a trailer to your vehicle, you should not use Active Parking Assist. Once the electrical connection is established between your vehicle and the trailer, Active Parking Assist is no longer available. PARKTRONIC is deactivated for the rear area. G WARNING While parking or pulling out of a parking space, the vehicle swings out and can drive onto areas of the oncoming lane. This could cause you to collide with other road users. There is a risk of an accident. 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 Z Driving and parking Problem 240 Driving systems sharp angle. Otherwise, you may damage the wheels or tyres. Driving and parking 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 237) warning messages during the parking procedure. Ryou can intervene in the steering procedure to correct it at any time. 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 that are: Rparallel or at right angles to the direction of travel straight roads, not bends Ron the same level as the road, e.g. not on the pavement Ron 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 there are objects above the detection range: RActive Park Assist may steer too early vehicle may not stop in front of these objects. This could cause a collision. There is a risk of an accident. If objects are located above the detection range, stop and switch off Active Parking Assist. Rthe Further information on the detection range (Y page 236). Active Parking Assist does not assist you parking in spaces at right angles to the direction of travel if: Rtwo parking spaces are located directly next to one another Rthe parking space is directly next to a low obstacle such as a low kerb Ryou forward park Active Parking Assist does not assist you parking in spaces that are parallel or at right angles to the direction of travel if: Rthe parking space is on a kerb 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 : 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. Active Parking Assist will only detect parking spaces: Rparallel or at right angles to the direction of travel are parallel to the direction of travel and are at least 1.5 m wide Rthat are parallel to the direction of travel and at least 1.0 m longer than your vehicle Rthat are at right angles to the direction of travel and at least 1.0 m wider than your vehicle Rthat driver's side is activated. When parking on the driver's side, this must remain switched on until you acknowledge the use of Active Parking Assist by pressing the a button on the multifunction steering wheel. The system automatically determines whether the parking space is parallel or at right angles to the direction of travel. A parking space is displayed while you are driving past it, and until you are approximately 15 m away from it. Parking G WARNING If you leave the vehicle when it is only being braked by Active Parking Assist it could roll away if: Rthere is a malfunction in the system or in the voltage supply. Rthe electrical system in the engine compartment, the battery or the fuses are tampered with. Rthe battery is disconnected. Rthe vehicle is accelerated, e.g. by a vehicle occupant. There is a risk of an accident. Before leaving the vehicle, always secure it against rolling away. i Vehicles with automatic transmis- sion: if PARKTRONIC detects obstacles, Active Parking Assist brakes automatically during the parking process. You are responsible for braking in good time. i Note that Active Parking Assist cannot measure the length of a parking space if it is at right angles to the direction of travel. You will need to judge whether your vehicle will fit in the parking space. When driving at speeds below 30 km/h, you will see parking symbol ; as a status indicator in the instrument cluster. When a parking space has been detected, an arrow towards the right or the left also appears. Active Parking Assist only displays parking spaces on the front-passenger side as standard. Parking spaces on the driver's side are displayed as soon as the turn signal on the Stop the vehicle when the parking symbol shows the desired parking space in the instrument cluster.

Vehicles with manual transmission: the Park Assist active Engage reverse gearObserve surroundings message appears in the multifunction display. As soon as the parking procedure is complete, the Park Assist switched off message appears and a warning tone sounds. The vehicle is now parked. Vehicles with automatic transmission: the vehicle is kept stationary without the driver having to depress the brake pedal. The braking effect is cancelled when you depress the accelerator pedal. Active Parking Assist no longer supports you with steering interventions and brake applications. When Active Parking Assist is finished, you must steer and brake again yourself. PARKTRONIC is still available. Parking tips: RThe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. It may be the case that Active Parking Assist guides you too far into a parking space, or not far enough into it. In some cases, it may also lead you across or onto the kerb. If necessary, you should cancel the parking procedure with Active Parking Assist. RYou can also preselect transmission position D. The vehicle redirects and does not drive as far into the parking space. Should the transmission change take place too early, the parking procedure will be cancelled. A sensible parking position can no longer be achieved from this position. Exiting a parking space In order that Active Parking Assist can support you when you exit the parking space: Rthe border of the parking space must be high enough at the front and the rear. A kerb stone is too small, for example. Rthe border of the parking space must not be too wide, as the position of the vehicle must not exceed an angle of 45° to the starting position as it is manoeuvred into the parking space. Ra manoeuvring distance of at least 1.0 m must be available. Active Parking Assist can only assist you with exiting a parking space if you have parked the vehicle parallel to the direction of travel using Active Parking Assist. i If PARKTRONIC detects obstacles, Active Parking Assist brakes automatically whilst the vehicle exits the parking space. You are responsible for braking in good time. Start the engine. Release the electric parking brake. X Switch on the turn signal in the direction you are pulling away. X Vehicles with automatic transmission: shift the transmission to position D or R. X X Vehicles with manual transmission: shift to forward or reverse gear. The Start Park Assist? Yes: OK No: % message appears in the multifunction display. X To cancel the procedure: press the % button on the multifunction steering wheel or pull away. or X To exit a parking space using Active Parking Assist: press the a button on the multifunction steering wheel. The Park Assist active Accelerate and brake Observe surroundings message appears in the multifunction display. X Release the multifunction steering wheel. X Pull away, being ready to brake at all times. Do not exceed a maximum speed of approximately 10 km/h when exiting a parking space. Otherwise, Active Parking Assist will be cancelled. X Vehicles with automatic transmission: depending on the message or as required, shift the transmission to position D or R. Vehicles with manual transmission: depending on the message or as required, engage forward or reverse gear. Active Parking Assist immediately steers in the other direction. The Park Assist active Accelerate and brake Observe surroundings message appears in the multifunction display. i You will achieve the best results by waiting for the steering procedure to complete before pulling away. If you reverse after activation, the steering wheel is moved to the straight-ahead position. X Drive forwards and reverse as prompted by the PARKTRONIC warning displays, several times if necessary. Once you have exited the parking space completely, the steering wheel is moved to the straight-ahead position. You hear a tone and the Park Assist switched off message Z 243 Driving and parking Driving systems Driving systems Driving and parking 244 appears in the multifunction display. You will then have to steer and merge into traffic on your own. PARKTRONIC is still available. You can take over the steering before the vehicle has exited the parking space completely. This is useful, for example when you recognise that it is already possible to pull out of the parking space. Reversing camera General notes Cancelling Active Parking Assist X Stop the movement of the multifunction steering wheel or steer yourself. Active Parking Assist will be cancelled at once. The Park Assist cancelled message appears in the multifunction display. or X Press the PARKTRONIC button (Y page 238). PARKTRONIC is switched off and Active Parking Assist is immediately cancelled. The Park Assist cancelled message appears in the multifunction display. Active Parking Assist is cancelled automatically if: Rthe electric parking brake is applied position P is selected in vehicles with automatic transmission Rparking using Active Parking Assist is no longer possible Ryou are driving faster than 10 km/h Ra wheel spins and ESP® intervenes or fails. The ÷ warning lamp lights up in the instrument cluster. A warning tone sounds. The parking symbol disappears and the multifunction display shows the Park Assist cancelled message. When Active Parking Assist is cancelled, you must steer and brake again yourself. If a system malfunction occurs, the vehicle is braked to a standstill. To drive on, depress the accelerator pedal again. Rtransmission Reversing camera : is in the boot lid handle. Reversing camera : is an optical parking and manoeuvring aid. It shows the area behind your vehicle with guidelines in the Audio 20/COMAND Online display.

It is active in the 60 km/h to 200 km/h range. If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break. Important safety notes ATTENTION ASSIST is only an aid. It may not always detect fatigue or lapses in concentration until too late, or may not detect them at all. The system is not a substitute for a wellrested and attentive driver. The functionality of ATTENTION ASSIST is restricted, and warnings may be delayed or not occur at all: Rif the length of the journey is less than approximately 30 minutes Rif the road condition is poor, e.g. if the surface is uneven or if there are potholes Rif there is a strong side wind You can have current status information displayed in the assistance menu (Y page 307) of the on-board computer.

The bar display then changes the display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h. Activating ATTENTION ASSIST X Activate ATTENTION ASSIST using the onboard computer (Y page 309). The system determines the attention level of the driver depending on the setting selected: Selection Standard Standard: the sensitivity with which the system determines the attention level is set to normal. Selection Sensitive Sensitive: the sensitivity is set higher. The attention level detected by Attention Assist is adapted accordingly and the driver is warned earlier. When ATTENTION ASSIST is deactivated, the é symbol appears in the multifunction display in the assistance graphic display. When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine has been stopped. The sensitivity selected corresponds to the last selection activated (standard/sensitive). Warning in the multifunction display If fatigue or increasing lapses in concentration are detected, a warning appears in the multifunction display: ATTENTION ASSIST Take a break!. break! In addition to the message shown in the multifunction display, you will then hear a warning tone. X If necessary, take a break. X Confirm the message by pressing the a button on the steering wheel. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break and ATTENTION ASSIST still detects increasing lapses in concentration, you will be warned again after 15 minutes at the earliest. This will only happen if ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. If a warning is output in the multifunction display, a service station search is performed in COMAND. You can select a service station and navigation to this service station will then begin. This function can be activated and deactivated in COMAND. Traffic Sign Assist General notes Traffic Sign Assist displays the maximum speed permitted and overtaking restrictions to the driver in the instrument cluster. Driving onto a section of road in the wrong direction triggers a warning. Traffic Sign Assist detects traffic signs with camera system : attached behind the top of the windscreen. The data and general traffic regulations stored in the navigation system are also used to determine the current speed limit. If a traffic sign that is relevant to your vehicle is passed, the display of the speed limits and overtaking restrictions is updated. Driving systems Rthe vehicle changes roads (e.g. motorway exit or slip road) Ra village or town boundary is passed which is stored in the digital map Rthe last traffic sign detected by the camera has not been repeated If a sign indicating the end of a restriction (speed limit or overtaking restriction) is passed, the sign is displayed for five seconds. The applicable traffic regulation then appears in the instrument cluster. The camera also detects traffic signs with a restriction indicated by an additional sign (e.g. in wet conditions). The traffic signs are only displayed with the restrictions if: Rthe regulation must be observed with the restriction, or RTraffic Sign Assist is unable to determine whether the restriction applies If Traffic Sign Assist is unable to determine a maximum permitted speed from any of the available sources, no speed limit is displayed in the instrument cluster either. always have priority over the Traffic Sign Assist display.

You will then also hear a warning tone. You should immediately check your direction of travel in order to avoid danger to yourself and other road users. Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 259) and Lane Keeping Assist (Y page 261). Blind Spot Assist General notes 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. Blind Spot Assist supports you from a speed of approximately 30 km/h. 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. Radar sensors The radar sensors for Blind Spot Assist are integrated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. 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 radar sensors checked at a qualified specialist workshop. Blind Spot Assist may no longer work properly.

Driving Assistance PLUS package General notes The Active Driving Assistance PLUS package consists of DISTRONIC PLUS (Y page 222), Active Blind Spot Assist (Y page 263) and Active Lane Keeping Assist (Y page 266). 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. Important safety notes Active Blind Spot Assist is only an aid and is not a substitute for attentive driving. G WARNING Active Blind Spot Assist does not react to vehicles: Rovertaking too closely on the side, placing them in the blind spot area Rif the difference in the speed of approach and overtaking is too great 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.

Hybrid operation Points to remember General notes Hybrid technology combines a fuel efficient internal combustion engine with a powerful electric motor. The hybrid system automatically selects the most efficient operating mode for every driving situation. Drive the vehicle in the usual manner. To save fuel, the hybrid system switches off the combustion engine as often as possible during the journey when power output requirements are low. When power output requirements are low, the electric motor powers the vehicle. When power output requirements are high, the combustion engine is switched on, even during a journey. When the vehicle is stationary, the combustion engine is usually switched off. Consequently, there is usually no engine idling as with combustion engine vehicles. For pulling away and accelerating, the electric motor supports the internal combustion engine using the power stored in the highvoltage battery. In addition, the power is used for partially electric driving, operation of the electric coolant compressor and to support the 12 V on-board electrical system. In this way the hybrid drive helps to reduce your vehicle's fuel consumption. Observe the driving tips on hybrid operation (Y page 278). RBS (Recuperative Brake System) If you release the accelerator pedal when the vehicle is in motion, overrun recuperation is initiated. The electric motor is operated as a generator when in overrun mode and when you brake. Hybrid technology converts the kinetic energy of the vehicle into electricity and stores it in the high-voltage battery. Important safety notes All of the vehicle's systems remain active, if: Rthe vehicle is stationary, combustion engine is switched off and Rthe READY-indicator in the instrument cluster is lit. If you remove your foot from the brake pedal while in transmission position D or R, the vehicle could pull away automatically. Observe the notes on the READY display of the ECO start/stop function (Y page 279). Vehicles with an electric motor generate significantly less noise than vehicles with internal combustion engines. As a result, in certain Rthe Z 269 Driving and parking Hybrid operation Driving and parking 270 Hybrid operation situations your vehicle may not be heard by other road users. This is the case, for example, when you are parking and your vehicle is not seen by other road users. This requires you to adopt a particularly anticipatory driving style, as it is necessary to allow for the possibility that other road users may behave unpredictably. Hybrid operation 271 Driving and parking Hybrid system overview : ; = ?

The electro-mechanically assisted steering gear allows use of the power steering without loss of comfort. Hybrid operation Rentirely by electric propulsion Rin combination with the internal combustion engine When accelerating at an increased or full load, boost mode is utilised. The electric motor supports the internal combustion engine by providing additional torque when the accelerator is depressed rapidly. Overrun mode or braking There are three possible operating modes when the hybrid vehicle is decelerating: RWhen coasting and decelerating, energy recuperation is already taking place (Y page 269). The electric motor functions as an alternator and stores the recuperated energy in the high-voltage battery. RWhen braking gently, the electric motor increases the deceleration of the vehicle. Energy recuperation is increased (Y page 269). The electric motor functions as an alternator and stores the recuperated energy in the high-voltage battery. RDuring heavy braking, the service brake is also used to slow down the vehicle. Both systems work together. Driving in the city Energy is recuperated during frequent deceleration and stopping in city traffic. The vehicle can be driven by the electric motor alone up to a speed of approximately 35 km/h, e.g.: Rwhile approaching a traffic light stop-and-start traffic The vehicle is driven by the electric motor alone only when all conditions for the automatic engine switch-off are fulfilled. Further information on the automatic engine switch-off (Y page 280). Driving on inter-urban roads Three phases are possible when driving on inter-urban roads: Rrapid acceleration (boost mode) energy consumption Renergy recuperation Depending on the characteristics of the route, there may be a lot of recuperated energy available. This reduces consumption and emissions. Rconstant Driving on the motorway When driving on a motorway, the following have a particularly positive effect on fuel consumption and emissions: Rthe decrease in wasted power when using recuperative braking Rthe decrease in wasted power in overrun mode when the combustion engine is switched off Manoeuvring and turning The hybrid drive makes it possible to manoeuvre and turn solely using the electric motor. ECO start/stop function General notes The ECO start/stop function switches the internal combustion engine off automatically when the vehicle stops moving and at high speeds (Y page 280). All vehicle systems remain active, e.g. the automatic climate control. The ECO start/stop function is only available in drive programs C, E and I. Electric-only operation is only possible in drive programs C and E. Rin Z Driving and parking Acceleration Depending on the operating mode, pulling away and driving under low load conditions are performed: 279 280 Hybrid operation Automatic engine switch-off The internal combustion engine is switched off automatically if: has reached the lower limit settings of the automatic climate control require it, e.g. at external temperatures above 30 † Rthe Rthe Driving and parking driver removes his foot from the accelerator pedal and a speed of 160 km/h is not exceeded (Y page 280) Rthe combustion engine and the transmission have reached operating temperature Rthe driver's seat belt is fastened and the driver's door is closed Rthe driver only slightly depresses the accelerator pedal in order to, for example, maintain the current speed for a limited distance Rthe bonnet is closed and engaged properly Rthe high-voltage battery is charged sufficiently Rthere are no faults in the hybrid system The internal combustion engine will not be switched off automatically, if: Rthe charge level of the high-voltage battery Rthe self-diagnosis function of the engine control unit is still active Rthe climate control of the vehicle requires it Rthe high-voltage battery is being charged (Y page 274) Rautomatic emissions tests are running Rthe operating temperature of the engine, transmission and catalytic converter has not yet been reached Automatic engine start The internal combustion engine, which has been automatically switched-off, starts automatically in certain situations, when: Rthe power demand from the driver via the accelerator pedal is greater than the electric motor alone can provide Rthe driver switches to drive program S or S + Rthe driver has activated manual gearshifting Overrun mode This operating mode is available in the speed range below 160 km/h.

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. Exceeding the maximum permissible noseweight of the trailer drawbar on the ball coupling may cause damage to the following: Ryour vehicle Rthe trailer Rthe ball coupling Rthe trailer tow hitch The vehicle/trailer combination could become unstable. If the noseweight used is lower than the minimum permissible noseweight, the vehicle/ trailer combination could also become unstable. To avoid hazardous situations: 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. 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 The applicable permissible values, which must not be exceeded, can be found: Rthe Rin your vehicle documents Ron the identification plates of the trailer tow hitch and the trailer the vehicle identification plate If the values differ, the lowest value applies. 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 478). Ron 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. Z Driving and parking Towing a trailer 283 284 Towing a trailer ! Depressing the brake pedal constantly Driving and parking results in excessive and premature wear to the brake pads. 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. When towing a trailer, your vehicle's handling characteristics will be different in comparison to when driving without a trailer. The vehicle/trailer combination: Ris heavier restricted in its acceleration and gradient-climbing capability Rhas an increased braking distance Ris affected more by strong crosswinds Rdemands more sensitive steering Rhas a larger turning circle This can impair the vehicle's handling characteristics. Adapt your driving style 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 Trailer towing is not permissible on the following models: RC 180 BlueEFFICIENCY Edition 220 BlueTEC BlueEFFICIENCY Edition When towing a trailer, set the tyre pressure on the rear axle of the towing vehicle for a maximum load; see the tyre pressure table in the fuel filler flap (Y page 432). RC 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 477). When towing a trailer, the ECO start/stop function is deactivated. The è ECO symbol appears yellow in the multifunction display. For further information on the ECO start/stop function; see (Y page 186). Driving tips Observe the notes on ESP® trailer stabilisation (Y page 82). 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 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 the "Technical data" section to find out whether this applies to your vehicle (Y page 478). 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. This also applies if cruise control, DISTRONIC PLUS or SPEEDTRONIC are activated. 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 Towing a trailer 285 Driving tips If the trailer swings from side to side: Do not accelerate. Do not countersteer. X Brake if necessary.

The indicator lamp on the release knob flashes. Do not attempt to speed this process up by applying additional pressure with your foot. The system could otherwise be mechanically damaged. 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 fitting the trailer electrics at a qualified specialist workshop. 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 181). Bulb failure indicator for LED lamps X Press the ball coupling in the direction of the arrow until it engages audibly behind the bumper. The indicator lamp on the release knob goes out and the message in the multifunction display disappears. Trailer power supply ! 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. 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 may 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.

G DANGER The vehicle's high voltage electrical system is under high voltage. If you modify components in the vehicle's high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehicle's high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury. Do not touch any high-voltage components after an accident and never modify the vehicle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system checked by a qualified specialist workshop. G WARNING In the event of a vehicle fire, the internal pressure of the high-voltage battery could exceed a critical value. In this case, flammable gas escapes through a vent valve in the vehicle's underbody. The gas can ignite. There is a risk of injury. Leave the danger area immediately. Secure the danger area at a suitable distance, whilst observing legal requirements. G WARNING If the housing of the high-voltage battery has been damaged, electrolyte and gases may leak out. These are poisonous and caustic. There is a risk of injury. Avoid contact with the skin, eyes or clothing. Immediately rinse electrolyte splashes off with water and seek medical attention straight away. ! Only charge the high-voltage battery in the "Charging when stationary" operating mode. Do not connect a battery charger to the high-voltage battery. Otherwise, the vehicle's high-voltage electrical system could be damaged. ! Exhaustive discharge caused by the vehicle standing idle for lengthy periods can damage the high-voltage battery. If the vehicle is idle for lengthy periods, run it for a few minutes once every six weeks to charge up the high-voltage battery. During the charging process, switch off all electrical consumers, e.g. the automatic climate control or the seat heating. If you wish to park your vehicle for several weeks, ensure that the battery is at least 30% charged. If necessary, charge the high-voltage battery while stationary before parking the vehicle (Y page 416).

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 432). Observe the notes on the emergency spare wheel (Y page 461). 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 429). 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.

There is a risk of accident. 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. 429 Wheels and tyres 430 Winter operation Therefore, only use tyre types and sizes approved for your vehicle model. Observe the tyre load rating and speed rating required for your vehicle. sure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tyres with a flat tyre (Y page 408). Pay special attention to country-specific requirements for tyre approval. These requirements can stipulate a specific tyre type for your vehicle. Furthermore, the use of certain tyre types in certain regions and areas of operation can be highly beneficial. You can find further information regarding tyres at specialist tyre retailers, at qualified specialist workshops or at any Mercedes-Benz Service Centre. 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 run-flat characteristics)" section (Y page 408). 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 461). i Vehicles with MOExtended tyres are not 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. MOExtended tyres may only be used in conjunction with an activated tyre pressure loss warning system or with an activated tyre pres- 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 438). 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 Winter operation 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. 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 an appropriate warning sign 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 221). When you have fitted the M+S tyres: Check the tyre pressures (Y page 432). Restart the tyre pressure loss warning system (Y page 437). X Restart the tyre pressure monitor (Y page 435). X X Information about driving with an emergency spare wheel (Y page 461). 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. ! Vehicles with steel wheels: if you fit snow chains on steel wheels, you may damage the hub caps. Remove the hub caps from the relevant wheels before fitting the snow chains. 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 444). 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 234). You may wish to deactivate ESP® (Y page 81) when pulling away with snow chains fitted. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). Z Wheels and tyres 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. 431 432 Tyre pressure Information about driving with an emergency spare wheel (Y page 461). Tyre pressure Tyre pressure specifications G WARNING Underinflated or overinflated tyres pose the following risks: Wheels and tyres Rthe tyres may burst, especially as the load and vehicle speed increase. Rthe tyres may wear excessively and/or unevenly, which may greatly impair tyre traction. Rthe driving characteristics, as well as steering and braking, may be greatly impaired. There is a risk of an accident.

Rwhen 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. 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 461). 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. G WARNING If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged. Tyre If a tyre size precedes a tyre pressure, the following tyre pressure information is only valid for that tyre size. Tyre pressure 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 10 kPa (0.1 bar/1.5 psi) per 10 †. Take this into account when checking the pressure of warm tyres. Only correct the tyre pressure if it is too low for the current operating conditions. Driving with tyre pressure that is too high or too low can: Rshorten the service life of the tyres increased tyre damage Rhave a negative effect on handling characteristics and thus driving safety (e.g. aquaplaning) 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. Rcause For Saloons at speeds of up to 210 km/h (does not apply to AMG vehicles, AMG Sport models): despite what is stated on the tyre pressure information label (fuel filler flap), at speeds of up to 210 km/h the values stated can be reduced as follows, without a reduction in safety: RSaloons (except Eco models): Ò30 kPa (Ò0.3 bar/Ò4 psi) RSaloons (Eco models with 16 or 17 in tyres on both axles): Ò60 kPa (Ò0.6 bar/ Ò9 psi) This does not apply to vehicles towing a trailer. This improves the ride comfort of your vehicle; however, fuel consumption may increase slightly. Tyre pressure monitor General notes If a tyre pressure monitor system is fitted, the vehicle's wheels have sensors fitted that monitor the tyre pressures in all four tyres. The tyre pressure monitor warns you if the pressure drops in one or more of the tyres. The tyre pressure monitor only functions if the corresponding sensors are fitted to all wheels. Information on tyre pressures is shown in the multifunction display. After a few minutes of driving, the current tyre pressure of each tyre is shown in the Service menu of the multifunction display, see illustration (example). Z Wheels and tyres 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: 433 434 Tyre pressure For further information on displaying this message, refer to the "Checking the tyre pressure electronically" section (Y page 434). Wheels and tyres 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 432). 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 reference values taught-in. Restart the tyre pressure monitor after adjusting to the cold tyre pressure (Y page 435). 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 the notes on the recommended tyre pressure (Y page 432). 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 tyre pressure monitor has a yellow warning lamp in the instrument cluster for indicating a pressure loss or malfunction. Depending on how the warning lamp flashes or lights up, a tyre pressure that is too low or a malfunction in the tyre pressure monitor is indicated: 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. In addition to the warning lamp, a message appears in the multifunction display. Further information can be found under (Y page 343). 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. Checking the tyre pressure electronically Make sure that the key is in position 2 (Y page 181) in the ignition lock. X Use ò on the steering wheel to call up the list of menus.

After a teach-in period, the tyre pressure monitor automatically detects new wheels or Tyre pressure Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure loss in one or more tyres, a warning message is shown in the multifunction display and the yellow tyre pressure monitor warning lamp comes on. RIf the Please correct tyre pressure message appears in the multifunction display, the tyre pressure in at least one tyre is too low and must be corrected at the next opportunity. RIf the Check tyre(s) message appears in the multifunction display, the tyre pressure in one or more tyres has dropped significantly and the tyres must be checked. RIf the Warning, tyre defect appears in the multifunction display, the tyre pressure in one or more tyres has dropped suddenly and the tyres must be checked. Observe the instructions and safety notes in the display messages in the "Tyres" section (Y page 343). If the wheel positions on the vehicle are interchanged, the tyre pressures may be displayed for the wrong positions for a short time. After a few minutes of driving, this is rectified and the tyre pressures are displayed for the correct positions. Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tyre pressures as the reference values for monitoring. In most cases, the tyre pressure monitor will automatically detect the new reference values after you have changed the tyre pressure. However, you can also define reference values manually as described here. The tyre pressure monitor then monitors the new tyre pressure values. X Use the table on the inside of the fuel filler flap to ensure that the tyre pressure is set correctly in all four tyres for the current operating conditions.

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 Service 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 437). 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 432).

Interchanging the wheels G WARNING Wheels and tyres 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. 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 438). 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 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 (Y page 437) or the tyre pressure monitor (Y page 435). 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 in a cool, dry and preferably dark place if they are not being used. Protect the tyres against oil, grease, petrol and diesel.

Only position the jack at the appropriate jacking point of the vehicle. The base of the jack Z Wheels and tyres iants, vehicles are not equipped with tyrechanging tools. Some tools for changing a wheel are specific to the vehicle. For more information on which tools are required to perform a wheel change on your vehicle, consult a qualified specialist workshop. Necessary wheel-changing tools may include, for example: 440 Changing a wheel must be positioned vertically, directly under the jacking point of the vehicle. Observe the following when raising the vehicle: Rto Wheels and tyres raise the vehicle, only use the vehiclespecific jack that has been tested and approved by Mercedes-Benz. If the jack is used incorrectly, it could tip over while the vehicle is raised. Rthe jack is designed only to raise and hold the vehicle for a short time while a wheel is being changed. It is not suitable for performing maintenance work under the vehicle. Ravoid changing the wheel on uphill and downhill slopes. Rbefore raising the vehicle, secure it from rolling away by applying the parking brake and positioning wheel chocks. Do not release the parking brake while the vehicle is raised. Rthe jack must be placed on a firm, flat and non-slip surface. On a loose surface, a large, flat load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be used, e.g. rubber mats. Rdo not use wooden blocks or similar objects as a jack underlay. Otherwise, the jack will not be able to achieve its loadbearing capacity due to the restricted height. Rmake sure that the distance between the underside of the tyres and the ground does not exceed 3 cm. Rnever place your hands or feet under the raised vehicle. Rdo not lie under the vehicle. Rdo not start the engine when the vehicle is raised. Rdo not open or close a door or the boot lid when the vehicle is raised.

X Removing a wheel ! Do not place wheel bolts in sand or dirt. The threads of the wheel bolts and wheel hubs could otherwise be damaged when the bolts are tightened. When fitting/removing wheels, and for as long as the wheels are removed, avoid applying any external force on the brake discs. This could impair the level of comfort when braking. G WARNING Oiled or greased wheel bolts or damaged wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could lose a wheel while driving. There is a risk of accident. Never oil or grease wheel bolts. In the event of damage to the threads, contact a qualified specialist workshop immediately. Have the damaged wheel bolts or hub threads replaced/renewed. Do not continue driving. G WARNING If you tighten the wheel bolts or wheel nuts when the vehicle is raised, the jack could tip over. There is a risk of injury. Only tighten the wheel bolts or wheel nuts when the vehicle is on the ground. Observe the instructions and safety notes on "Changing a wheel" (Y page 438).

Only restart the tyre pressure loss warning system when the defective wheel has been replaced with a new wheel. Z Wheels and tyres X 444 Wheel and tyre combinations 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) Wheels and tyres RMO1 = Mercedes-Benz Original (only cer- 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. Further information about wheels, tyres and approved combinations can be obtained from any qualified specialist workshop. ! Retreaded tyres are neither tested nor 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 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 432). 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) Exception: it is permissible to fit a different type or make in the event of a flat tyre. Observe the "MOExtended tyres (tyres with run-flat characteristics" section (Y page 408). 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. i Not all wheel/tyre combinations can be fitted at the factory in all countries. Wheel and tyre combinations 445 Tyres C 180 Summer tyres R 16 Tyres Wheels BA: 195/65 R16 92 V1 BA: 6.0 J x 16 H2 ET 36.5 BA: 205/60 R16 92 V1 BA: 6.0 J x 16 H2 ET 36 BA: 205/60 R16 92 V1 BA: 6.0 J x 16 H2 ET 36.5 BA: 205/60 R16 92 V2 BA: 6.5 J x 16 H2 ET 38 BA: 225/55 R16 95 V3, 2 BA: 7.0 J x 16 H2 ET 48 Tyres Wheels BA: 225/50 R17 94 W3 BA: 7.0 J x 17 H2 ET 48.5 FA: 225/50 R17 94 W3 RA: 245/45 R17 95 W3 FA: 7.0 J x 17 H2 ET 48.5 RA: 8.0 J x 17 H2 ET 54 Wheels and tyres R 17 R 18 Tyres Wheels FA: 225/45 R18 95 Y XL3 RA: 245/40 R18 97 Y XL3 FA: 7.5 J x 18 H2 ET 44 RA: 8.5 J x 18 H2 ET 56 FA: 225/45 R18 95 Y XL3 RA: 245/40 R18 97 Y XL3, 4 FA: 7.5 J x 18 H2 ET 44 RA: 8.5 J x 18 H2 ET 49 Not in conjunction with Avantgarde exterior package (code P15), Exclusive exterior package (code P23), AMG Line Exterior package (code P31), dynamic handling package (code 483/489), suspension for greater ground clearance (code 482) and sports suspension (code 486). 2 Not in conjunction with AMG Line exterior package (code P31), suspension for greater ground clearance (code 482) and sports suspension (code 486). 3 Available as MOExtended tyres. 4 Additional measures necessary (additional wheel-arch extension on rear wheel arch). 1 Z Wheel and tyre combinations 446 R 19 Tyres Wheels FA: 225/40 R19 93 Y XL3 RA: 245/35 R19 93 Y XL3 FA: 7.5 J x 19 H2 ET 44 RA: 8.5 J x 19 H2 ET 56.5 FA: 225/40 R19 93 Y XL3 RA: 255/35 R19 96 Y XL3, 4 FA: 7.5 J x 19 H2 ET 44 RA: 8.5 J x 19 H2 ET 52 Wheels and tyres Winter tyres R 16 Tyres Wheels BA: 205/60 R16 92 V M+S i1 BA: 6.0 J x 16 H2 ET 36 BA: 205/60 R16 92 H M+Si1 BA: 6.0 J x 16 H2 ET 36.5 BA: 205/60 R16 92 H M+Si2 BA: 6.5 J x 16 H2 ET 38 BA: 225/55 R16 95 H M+Si3, 2 BA: 7.0 J x 16 H2 ET 48 R 17 Tyres Wheels BA: 225/50 R17 94 H M+Si3 BA: 7.0 J x 17 H2 ET 48.5 R 18 Tyres BA: 225/45 R18 95 H XL Wheels M+Si3 BA: 7.5 J x 18 H2 ET 44 Available as MOExtended tyres.

More information about the interval for oil change can be obtained from any qualified specialist workshop. Technical data 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 201). 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 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. The vehicle will use more fuel than usual in the following situations: Rat very low outside temperatures urban traffic Ron short journeys Rin mountainous terrain Rwhen towing a trailer Rin 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). These documents are delivered with your vehicle. The consumption figures were, in each case, based on the currently applicable version: Rfor vehicles that comply with standards up to and including the EURO 4 standard, in accordance with EU Directive 80/1268/EEC Rfor vehicles that comply with or exceed the Euro 5 standard, in accordance with Regulation (EC) No. 715/2007 Deviations from these values may occur under normal operating conditions. AdBlue® Important safety notes 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. Service products and capacities Capacities The total capacity of the AdBlue® tank may vary, depending on the vehicle equipment. Low outside temperatures Model AdBlue® All models 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 †. Total capacity 8.5 l or 24.5 l Engine oil Additives General notes ! Only use AdBlue® in accordance with ISO When handling engine oil, observe the important safety notes on service products (Y page 468). 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. The table shows which engine oils have been approved for your vehicle. 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 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. Z Technical data Do not inhale any ammonia vapours that may be released. Only fill the AdBlue® tank in wellventilated areas. 473 474 Service products and capacities Petrol engines: in certain countries, different engine oils can be used, provided that the maintenance intervals are reduced.

Engine oil viscosity i If the engine oils listed in the table are not available, you may add the following engine oils until the next oil change: Rvehicles with a petrol engine: MB Approval 229.1, 229.3 or ACEA A3 Rvehicles with a diesel engine: MB Approval 229.1, 229.3, 229.5 or ACEA C3 This must only be added once and the amount must not be greater than 1.0 l. Capacities The following values refer to an oil change, including the oil filter. 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. Service products and capacities 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. When handling brake fluid, observe the important safety notes on service products (Y page 468). The brake fluid change intervals can be found in the Service Booklet. Only use brake fluid approved by MercedesBenz according to MB Approval 331.0. 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. 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. The coolant is a mixture of water and antifreeze/corrosion inhibitor. It is responsible for the following: Ranti-corrosion protection protection Rraising the boiling point If antifreeze/corrosion inhibitor is present in the correct concentration, the boiling point of the coolant during operation will be approximately 130 †. The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rantifreeze Rbe at least 50%. This will protect the engine cooling system against freezing down to approximately -37 †. Rnot exceed 55% (antifreeze protection down to -45 †). Heat will otherwise not be dissipated as effectively. Mercedes-Benz recommends an antifreeze/ corrosion inhibitor concentrate in accordance with MB Specifications for Service Products 310.1 . The coolant is checked at every maintenance interval at a qualified specialist workshop. i When the vehicle is first delivered, it is filled with a coolant mixture that ensures Z Technical data Brake fluid 475 Vehicle data 476 adequate antifreeze and corrosion protection. i The coolant is checked at every maintenance interval at a qualified specialist workshop.
