Our objectives are to use the natural resources which form the basis of our existence on this planet sparingly and in a manner which takes the requirements of both nature and humanity into consideration. You too can help to protect the environment by operating your vehicle in an environmentally-responsible manner. Fuel consumption and the rate of engine, transmission, brake and tyre wear depend on the following factors: Roperating conditions of your vehicle personal driving style You can influence both factors. Therefore, please bear the following in mind: Operating conditions: Ryour short trips, as these increase fuel consumption. Robserve the correct tyre pressure. Rdo not carry any unnecessary weight in the vehicle. Rremove the roof rack once you no longer need it. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Rall maintenance work should be carried out at a qualified specialist workshop. Personal driving style: Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. off the engine in stationary traffic. Rmonitor the vehicle's fuel consumption. Rswitch Returning an end-of-life vehicle EU countries only: Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-responsible manner in accordance with the European Union (EU) End of Life Vehicles Directive. There is a network of return points and disassembly plants available. You can return your vehicle to these plants free of charge. This makes a valuable contribution to the recycling process and the conservation of resources. For further information on recycling old vehicles, recovery and the terms of the policy, visit the Mercedes-Benz homepage. Ravoid Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine when the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. Ravoid frequent, sudden acceleration and braking. Genuine Mercedes-Benz parts H Environmental note Daimler AG also supplies reconditioned assemblies and parts which are of the same quality as new parts. For these, the same warranty applies as for new parts. ! Airbags and seat belt tensioners, as well as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars sills Rseats Rdashboard Rinstrument cluster Rcentre console Rdoor Introduction Do not install accessories such as audio systems in these areas. Do not carry out repairs or welding. You could impair the operating efficiency of the restraint systems. Have accessories retrofitted at a qualified specialist workshop. You could jeopardise the operating safety of your vehicle if you use parts, tyres and wheels as well as accessories relevant to safety which have not been approved by MercedesBenz. This could lead to malfunctions in safety-relevant systems, e.g. the brake system. Only use 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) (Y page 402) when ordering genuine Mercedes-Benz parts. Owner's Manual Vehicle equipment This Owner's Manual describes all models and all standard and optional equipment available for your vehicle at the time of publication of the Owner's Manual. Country-specific differences are possible. Note that your vehicle may not be fitted with all features described. This is also the case for systems and functions relevant to safety. Therefore, the equipment on your vehicle may differ from that in the descriptions and illustrations. The original purchase contract documentation for your vehicle contains a list of all of the systems in your vehicle. Should you have any questions concerning equipment and operation, please consult a Mercedes-Benz Service Centre. The Owner's Manual and Service Booklet are important documents and should kept in the vehicle. Operating safety Important safety notes G WARNING If you do not have the prescribed service/ maintenance work or necessary repairs carried out, this could result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/maintenance work as well as necessary repairs carried out at a qualified specialist workshop. G WARNING 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 Z 23 24 Introduction 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 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 con- tinuing 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.

Occupant safety Introduction to the restraint system The restraint system can reduce the risk of vehicle occupants coming into contact with parts of the vehicle's interior in the event of an accident. The restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. The restraint system comprises: RSeat belt system RAirbags RChild Panic alarm restraint system seat securing systems The components of the restraint system work in conjunction with each other. They can only deploy their protective function if all vehicle occupants always: RChild Rfasten To activate: press and hold the ! button : for approx. one second. A visual and audible alarm is triggered if the alarm system is primed. X To deactivate: press the ! button : again. or X Insert the key into the ignition lock. or, on vehicles with KEYLESS-GO start function or KEYLESS‑GO X Press the Start/Stop button. The key must be in the vehicle. X The panic alarm function is only available in certain countries. their seat belts correctly (Y page 46) Radjust their seat and head restraint properly (Y page 113). As the driver, you also have to make sure that the steering wheel is adjusted correctly. Observe the information relating to the correct driver's seat position (Y page 112). You also have to make sure that an airbag can inflate properly if deployed (Y page 48). An airbag supplements a correctly fastened seat belt. As an additional safety device, the airbag increases the level of protection for vehicle occupants in the event of an accident. For example, if the protection of the seat belt is sufficient in an accident, the airbags are not deployed. In the event of an accident, only the airbags that increase protection in the relevant accident situation are deployed. However, seat belts and airbags generally do not protect against objects penetrating the vehicle from the outside. Information on the restraint system operation can be found under "Triggering of belt tensioners and airbags" (Y page 57). For more information about children travelling with you in the vehicle, see "Children in the vehicle" (Y page 59). Important safety notes G WARNING If the restraint system is modified, it may no longer work as intended. The restraint system may then not perform its intended protective function by failing in an accident or triggering unexpectedly, for example. There is an increased risk of injury, possibly even fatal. Never modify parts of the restraint system. Do not attempt to modify the wiring as well as electronic components or their software. G WARNING If the restraint system is malfunctioning, restraint system components may be triggered unintentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. This can effect belt tensioners or airbags, for example. There is an increased risk of serious or even fatal injuries. Have the restraint system checked and repaired immediately at a qualified specialist workshop. PASSENGER AIR BAG indicator lamp If it is necessary to modify an airbag system to accommodate a person with disabilities, contact a Mercedes-Benz Service Centre for details. Restraint system warning lamp The functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time. The 6 restraint system warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up after the ignition is switched on Rdoes not go out after a few seconds with the engine running Rlights up again while the engine is running PASSENGER AIR BAG ON indicator lamp : and PASSENGER AIR BAG OFF indicator lamp ; are part of the automatic 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 event 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. Z 43 Safety Occupant safety 44 Occupant safety Safety 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. It is imperative to observe the notes on the "Automatic front-passenger front airbag deactivation system" (Y page 51) and on "Children in the vehicle" (Y page 59). RChildren in a forward-facing child restraint system: depending on the installed child restraint system and the age and size of the child, the front-passenger front airbag is either disabled or enabled. Therefore, it is imperative to observe the notes on the "Automatic front-passenger front airbag deactivation system" (Y page 51) and on "Children in the vehicle" (Y page 59). 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. It is imperative to observe the notes on the "Automatic front-passenger front airbag deactivation system" (Y page 51) as well as on "Seat belts" (Y page 44) and "Airbags" (Y page 48). There you can also find information on the correct seat position. Seat belts Introduction A correctly worn seat belt 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 ejected from it. The seat belt also helps to keep the vehicle occupants in the best position in relation to the airbag being deployed. 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 quickly or sharply from the belt outlet, the inertia reel locks. The belt strap cannot be pulled out any further. The belt tensioner tightens the seat belt in the event of a collision so that it fits tightly across your body. However, it does not pull the vehicle occupants back in the direction of the seat backrest. The belt tensioner does not, however, correct an incorrect seat position or correct the routing of a seat belt that is worn incorrectly. When triggered, seat belt force limiters help to reduce the peak force exerted by the seat belt on the vehicle occupant. The belt force limiters on the front seats are synchronised with the front airbags, which take on a part of the deceleration force. This can reduce the forces to which the 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. There is an increased risk of injury, possibly even fatal. Secure persons less than 1.50 m tall in a suitable restraint system. If a child younger than twelve 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 this Mercedes-Benz vehicle. The child restraint system must be appropriate to the age, weight and size of the child. Ralways observe the instructions and safety notes on the automatic front-passenger front airbag deactivation system (Y page 51) Ralways observe the instructions and safety notes on "Children in the vehicle" in this Owner's Manual (Y page 59) in addition to the child restraint system manufacturer's installation instructions G WARNING Seat belts cannot protect as intended, if: Rthey are damaged, have been modified, are extremely dirty, bleached or dyed seat belt buckle is damaged or extremely dirty Rmodifications have been made to the belt tensioners, belt anchorages or inertia reels Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. 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. Otherwise, your vehicle's general operating permit could be invalidated. Sports seat or AMG Performance seat: this seat is designed for the standard three-point seat belt. If you fit another multipoint seat belt, e.g. sport or racing seat belts, the restraint system cannot provide the best level of protection. G WARNING If you feed seat belts through the opening in the seat backrest, the seat backrest may be damaged or may even break in the event of an Z 45 Safety Occupant safety 46 Occupant safety Safety accident. This poses an increased risk of injury or even fatal injury. Only use the standard three-point seat belt. Never modify the seat belt system. Correct seat belt use Observe the safety notes on the seat belt (Y page 44). All vehicle occupants must be wearing the seat belt correctly before beginning the journey. Also make sure that all vehicle occupants are always wearing the seat belt correctly while the vehicle is in motion. When fastening the seat belt, always make sure that: Infants and children must never travel sitting on the lap of a vehicle occupant. In the event of an accident, they could be crushed between the vehicle occupant and seat belt. Robjects are never secured with a seat belt if the seat belt is also being used by one of the vehicle's occupants Also ensure that no objects are placed between a person and the seat. e.g. a cushion. Seat belts are only intended to secure and restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects, luggage or loads (Y page 316).

It may Z Safety 48 Occupant safety light up continuously or flash. A warning tone may also sound. The 7 seat belt warning lamp goes out and the warning tone stops as soon as the driver's and the co-driver's seat belts have been fastened. i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belt" (Y page 301). Rear seat belt status indicator 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 57). 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 The seat belts on the left and centre rear seats, when viewed in the direction of travel, are not fastened. (Example) 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 You can also cancel the rear seat belt status indicator immediately (Y page 265). Airbags Introduction The installation location of an airbag is identified by the AIRBAG symbol. 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 Occupant safety RAlways secure children under twelve years of age and less than 1.50 m tall in suitable child restraint systems. RChild restraint systems should be fitted to the rear seats. ROnly secure a child to the front-passenger seat when the front-passenger front airbag is disabled, and only then in a rearwardfacing child restraint system. If the PASSENGER AIR BAG OFF indicator lamp is permanently lit, the front-passenger front airbag is disabled (Y page 43). RAlways observe the instructions and safety notes on the automatic front-passenger front airbag deactivation system (Y page 51) and on "Children in the vehicle" (Y page 59) in addition to the child restraint system manufacturer's installation instructions. 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, are hanging 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. Z Safety 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. RAlways 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: 49 Occupant safety Driver's kneebag : deploys under the steering column. The driver's kneebag is triggered together with the front airbags. The driver's kneebag offers additional thigh, knee and lower leg protection for the occupant in the driver's seat. Safety 50 i The driver's kneebag is only available in certain countries. Sidebags Driver's airbag : deploys in front of the steering wheel. Front-passenger front airbag ; deploys in front of and above the glove compartment. When deployed, the front airbags offer additional head and thorax protection for the occupants in the front seats. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you about the status of the frontpassenger front airbag (Y page 43). The 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 51). The PASSENGER AIR BAG ON indicator lamp is lit (Y page 52) Rthe restraint system control unit predicts a high accident severity 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. Driver's kneebag Front sidebags : and rear sidebags ; deploy next to the outer bolster of the seat backrest. When deployed, the sidebag offers additional thorax protection. It also offers additional pelvis protection for occupants in the front seats.

When deployed, the windowbag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the windowbag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a windowbag may be deployed in other accident situations (Y page 57). 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 63). If this is not the case, always install a child restraint system on a suitable rear seat (Y page 65). 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. a cushion. 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 forward-facing child restraint system must, as far as possible, be resting on the backrest of the front-passenger seat. The 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 65) in addition to the child Rthe Z Safety In the event of a side impact, the sidebag is deployed on the side on which the impact occurs.

Safety Operation of automatic front-passenger front airbag deactivation tion 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 a person sits in the passenger seat, they must be: Rseated with the seat belt fastened correctly Rin : 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 event 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 278). When the frontpassenger seat is occupied, always pay atten- 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. 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 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 disa- bled 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 56). 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 child 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.

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 59). 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.

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. You can find further information under: "Restraint system warning lamp" (Y page 43) 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 accident, in certain head-on collisions, additional components of the restraint system are deployed independently of each other: Rfront airbags and driver's kneebag Rwindowbag, 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 43). Your vehicle has two-stage front airbags. In the first deployment stage, the front airbag is Z Safety Deployment of belt tensioners and airbags 57 Safety 58 Occupant safety filled with propellant gas to reduce the risk of 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, the applicable components of the restraint system are activated independently of each other. RSidebags on the side on which an impact occurs, independent from the seat belt tensioner and seat belt usage Vehicles with the automatic frontpassenger airbag deactivation system: the sidebag on the front-passenger side 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 RSeat belt tensioners, if the system determines that deployment can offer additional protection for the vehicle occupants in this situation i Not all airbags are deployed in an acci- dent.

Rvehicles with the memory function: the front-passenger seat is adjusted if it is in an unfavourable position. If the hazardous situation passes without resulting in an accident, PRE-SAFE® slackens the belt pre-tensioning. All settings made by PRE-SAFE® can then be reversed. If the seat belt pre-tensioning is not reduced: Rif X Move the seat backrest or seat back slightly when the vehicle is stationary. Seat belt pre-tensioning is reduced and the locking mechanism is released. The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function.

Children could be suffer burns by touching these parts, in particular on the metallic parts of the child restraint system. There is a risk of injury. If you and your child leave the vehicle, always make sure that the child restraint system is not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has been exposed to direct sunlight, leave it to cool down before securing the child in it. Never leave children unattended in the vehicle. Always ensure that all vehicle occupants have their seat belts fastened correctly and are sitting properly. Particular attention must be paid to children. Observe the safety notes on the seat belt (Y page 44) and the information on the correct use of the seat belt (Y page 46). Child restraint system If you fit a rearward-facing child restraint system to the centre rear seat, the rear arm rest must be folded back as far as possible. Observe the instructions for correct use of the child restraint system (Y page 65). For safety reasons, Mercedes-Benz recommends that you only use a child restraint system recommended by Mercedes-Benz (Y page 69). G WARNING If the child restraint system is incorrectly fitted on the seat position suitable for this purpose, it cannot perform its intended protective function. In the event of an accident, sharp braking or a sudden change in direction, the child may not be held securely. There is an increased risk of serious or even fatal injuries. Observe the manufacturer's installation instructions and the correct use for the child restraint system. Make sure that the entire surface of the child restraint system is resting on the seat surface. Never place objects under or behind the child restraint system, e.g. cushions. Only use child restraint systems with the original cover designed for them. Only replace damaged covers with genuine covers. G WARNING If the child restraint system is fitted incorrectly or is not secured, it can come loose in the event of an accident, heavy braking or a sudden change in direction. The child restraint system could be thrown about, striking vehicle occupants. There is an increased risk of injury, possibly even fatal.

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. NEVER use a rearward facing child restraint on a seat protected by an ACTIVE AIRBAG in front of it; DEATH or SERIOUS INJURY to the CHILD can occur. If the PASSENGER AIR BAG ON indicator lamp is lit, the front-passenger front airbag is enabled (Y page 43). If the front-passenger seat of your vehicle is not equipped with the automatic frontpassenger front airbag deactivation system, this is indicated by a special sticker. The sticker is affixed to the side of the dashboard on the front-passenger side. The sticker is visible when you open the front-passenger door. If you turn the key to position 2 in the ignition lock, the PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps light up briefly. However, they have no function and do not indicate that there is an automatic front-passenger front airbag deactivation system. Always fit the rearward-facing restraint system to a suitable rear seat in this case (Y page 65). Observe the following information under "Rearward-facing child restraint system" and "Forward-facing child restraint system" as well as information on the suitable positioning of the child restraint system (Y page 65). Rearward-facing child restraint system If it is absolutely necessary to fit a rearwardfacing child restraint system to the frontpassenger seat, always make sure that the front-passenger front airbag is disabled. Only if the PASSENGER AIR BAG OFF indicator lamp is lit continuously (Y page 43)is the front-passenger front airbag disabled. Always observe the information on suitable positioning of the child restraint system (Y page 65) in addition to the child restraint system manufacturer's installation and operating instructions. Forward-facing child restraint system If it is absolutely necessary to fit a forwardfacing child restraint system to the frontpassenger seat, always move the frontpassenger seat as far back as possible. Fully retract the seat cushion length. The entire base of the child restraint system must always rest on the seat cushion of the frontpassenger seat. The backrest of the child restraint system must, as far as possible, lie flat against the backrest of the frontpassenger seat. The 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. 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.

They could: Ractivate vehicle equipment and become trapped, for example Rswitch vehicle systems on or off, thus endangering other road users In the event of an accident, sudden braking or abrupt changes of direction, unsecured animals could be flung around the vehicle, injuring the vehicle occupants. There is a risk of an accident and injury. Never leave animals unattended in the vehicle. Always secure animals correctly during a journey, e.g. in an animal transport box. If you fail to adapt your driving style or if you are inattentive, the driving safety systems can neither reduce the risk of an accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for maintaining the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. The driving safety systems described only work as effectively as possible when there is adequate contact between the tyres and the road surface. Please pay special attention to the notes on tyres, recommended minimum tyre tread depths etc. (Y page 370). 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. Driving safety systems 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. ABS works from a speed of about 8 km/h, regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. Important safety notes i Observe the "Important safety notes" section (Y page 72). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop. If ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 304) and display messages which may be shown in the instrument cluster (Y page 266). The pulsating brake pedal can be an indication of hazardous road conditions; this serves as a reminder to take extra care while driving. BAS (Brake Assist) General notes BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. Important safety notes i Observe the "Important safety notes" section (Y page 72). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking. Braking X Keep the brake pedal depressed firmly until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. COLLISION PREVENTION ASSIST PLUS Brakes General notes 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. i Observe the "Important safety notes" sec- X If ABS intervenes when braking, you will feel a pulsing in the brake pedal. tion (Y page 72). COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autonomous braking function and Adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimise the risk of a collision Z Safety ABS (Anti-lock Braking System) 73 Safety 74 Driving safety systems 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 Detection of hazardous situations can be particularly impaired by: 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 Observe the important safety notes in the "Running-in notes" section (Y page 164). 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 Activating/deactivating The COLLISION PREVENTION ASSIST PLUS is automatically active after switching on the ignition. You can activate or deactivate COLLISION PREVENTION ASSIST PLUS in the on-board computer (Y page 256). When deactivated, the distance warning function and the autonomous braking function are also deactivated. If COLLISION PREVENTION ASSIST PLUS is deactivated, the æ symbol appears in the assistance graphics display. Distance warning function General notes 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. Important safety notes i Observe the "Important safety notes" section for driving safety systems (Y page 72). G WARNING The distance warning function does not react: Rto people or animals Rto 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. 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 The distance warning function issues a warning at speeds: Vehicles without DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: Rof approximately 30 km/h or more, if, over R7 several seconds, the distance maintained to the vehicle travelling in front is insufficient. 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. 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 - 105 km/h for moving objects - 50 km/h for stationary objects Vehicles with DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R7 R7 - 200 km/h for moving objects - 50 km/h for stationary objects Due to the nature of the system, complicated but non-critical driving conditions may also cause the Autonomous Braking function to intervene. If the autonomous braking function demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously (Y page 58). R7 Adaptive Brake Assist General notes i Observe the "Important safety notes" section (Y page 72). 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. 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. 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. Z 75 Safety Driving safety systems Safety 76 Driving safety systems Up to a speed of approximately 70 km/h, Adaptive Brake Assist reacts to stationary obstacles. If Adaptive Brake Assist demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously (Y page 58). X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal Rthere is no longer any danger of a collision Rno obstacle is detected in front of your vehicle Adaptive Brake Assist is then deactivated. Important safety notes i Observe the "Important safety notes" section for driving safety systems (Y page 72). 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 Rto 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. Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause Brake Assist to intervene. If Adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. Adaptive brake lights The adaptive brake lights warn following traffic in an emergency braking situation: Rby flashing brake lamps hazard warning lamps are activated 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 129). Rthe ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes" section (Y page 72). 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. Only use wheels with the recommended tyre sizes. Only then will ESP® function properly. ETS/4ETS (Electronic Traction System) Characteristics of ESP® i Observe the "Important safety notes" sec- General notes If the ÷ ESP warning lamp goes out before beginning the journey, ESP® is automatically active. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. tion (Y page 72). 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 72). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilise the vehicle. In addition, other driving safety systems are switched off. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop. Vehicles without 4MATIC: when towing away your vehicle with the front axle raised, please observe the notes on ESP® (Y page 364). If the å ESP® OFF warning lamp lights up continuously, ESP® is deactivated. If the ÷ ESP® warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 306) and display messages which may be shown in the instrument cluster (Y page 266). If ESP® intervenes: Do not deactivate ESP® under any circumstances. X When pulling away, only depress the accelerator pedal as far as is necessary. X Adapt your driving style to suit the prevailing road and weather conditions. X ECO start/stop function The ECO start/stop function switches the engine off automatically if the vehicle stops moving. When pulling away again, the engine starts automatically. ESP® remains in its previously selected status. Example: if ESP® was deactivated before the engine was switched off, ESP® remains deactivated when the engine is switched on again. Deactivating/activating ESP® (except Mercedes‑AMG vehicles) Important safety notes You can select between the following statuses of ESP®: RESP® RESP® is activated is deactivated G WARNING If you deactivate ESP®, ESP® no longer stabilises the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following.

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. Vehicles with bi-xenon or halogen headlamps It is not necessary to switch your headlamps to symmetrical dipped beam when driving in countries where vehicles are driven on the opposite side of the road to the country in which the vehicle is registered. Legal require- 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 259). If the headlamps are converted to symmetrical dipped beam, the "motorway mode" and "extended range foglamps" functions are not available. Setting the exterior lighting Setting options Exterior lighting can be set using the: Rlight switch Rcombination switch (Y page 129) range adjustment (only vehicles with halogen headlamps) (Y page 128) Ron-board computer (Y page 259) Rheadlamp Light switch Operation 1 W Left-hand parking lamps 2 X Right-hand parking lamps 3 T Side lamps, licence plate and instru- ment cluster lighting Exterior lighting led by the light sensor 5L Dipped-beam/main-beam head- lamps B R Rear foglamp C N Foglamp (vehicles with front fog- lamps only) If you hear a warning tone when you leave the vehicle, the lights may still be switched on.

Cornering light function Intelligent Light System General notes The Intelligent Light System is a system that adjusts the headlamps automatically to suit the prevailing driving and weather conditions. It offers advanced functions for improved illumination of the road surface, e.g. depending on the vehicle speed or weather conditions. The system includes the active light function, cornering light function, motorway mode and extended range foglamps. The system is only active when it is dark. You can activate or deactivate the "Intelligent Light System" function using the on-board computer (Y page 259). 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 light function may remain lit for a short time, but is automatically switched off after no more than three minutes. Motorway mode The active light function is a system that moves the headlamps according to the steering movements of the front wheels. In this Exterior lighting 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. 131 Adaptive Highbeam Assist General notes 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. You can use this function to set the headlamps to change between dipped beam and main beam automatically. The system recognises vehicles with their lights on, either approaching from the opposite direction or travelling in front of your vehicle, and consequently switches the headlamps from main beam to dipped beam. The system automatically adapts the dippedbeam headlamp range depending on the distance to the other vehicle. Once the system no longer detects any other vehicles, it switches on the main-beam headlamps again. The system's optical sensor is located behind the windscreen near the overhead control panel.

National variations are possible. Note that your vehicle may not be equipped with all of the functions described. This is also the case for systems and functions relevant to safety. i Read the information on qualified special- Climate control ist workshops: (Y page 25). Overview of climate control systems General notes Observe the settings recommended on the following pages. The windows could otherwise mist up. To prevent the windows from misting up: Rswitch off climate control only briefly air-recirculation mode only briefly Ractivate the "Cooling with air dehumidification" function Ractivate the windscreen demisting function briefly, if required The air-conditioning system/ THERMOTRONIC automatic climate control regulates the temperature and the humidity of the vehicle interior and filters undesirable substances from the air. The air-conditioning system/ THERMOTRONIC automatic climate control can only be operated when the engine is running. Optimum operation is only achieved with the side windows and panorama sliding sunroof closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 155). Always keep the ventilation flaps behind the side panelling clear (Y page 136). Otherwise the vehicle will not be ventilated correctly. Ractivate i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 102). 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. With THERMOTRONIC automatic climate control, gaseous pollutants and odours will also be reduced. 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 Vehicles with auxiliary heating: under certain environmental conditions, the residual heat function may be activated automatically an hour after the key has been removed in order to dry the automatic climate control. When the automatic climate control drying function is active, the blue LED lamp is lit in the rocker switch in the centre console. The vehicle is then ventilated for 30 minutes. Vehicles without auxiliary heating: under certain environmental conditions, the residual heat function may be activated automatically an hour after the key has been removed in order to dry the automatic climate control. The vehicle is then ventilated for 30 minutes. Overview of climate control systems 145 : ; = ?

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. When the auxiliary heating is switched on, make sure that: Rthe 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 and the exhaust gas outlet are situated in front of the right-hand front wheel. ! 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 timer function calculates the switch-on time according to the outside temperature so that the vehicle is preheated by the departure time. When the departure time is reached, the auxiliary heating continues to heat for a further five minutes and then switches off. The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs without using the heat of the running engine. The auxiliary heating is operated directly using the vehicle's fuel. For this reason, the fuel tank must be at least Õ full to ensure that the auxiliary heating functions. The auxiliary heating/ventilation automatically adjusts to changes in temperature and weather conditions. For this reason, the auxiliary heating could switch from ventilation mode to heating mode or from heating mode to ventilation mode. Operating the climate control system Before switching on Turn the key to position 2 in the ignition lock (Y page 165).

This is also the case for systems and functions relevant to safety. i Read the information on qualified specialist workshops: (Y page 25). 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 1500 km, you may gradually bring the vehicle up to full road and engine speeds. Additional notes on running in MercedesAMG vehicles: Rfor the first 1,500 km do not drive at speeds above 140 km/h. allow the engine to reach a maximum engine speed of 4,500 rpm briefly. 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 maximum permissible speed. Ronly 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 process. Brake pads/linings and discs that are either new or have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal. The first 1500 km If you treat the engine with sufficient care from the very start, you will be rewarded with excellent performance for the remainder of the engine's life. RDrive at varying vehicle speeds and engine speeds for the first 1500 km. RAvoid overstraining the vehicle during this period, e.g. driving at full throttle. RChange gear in good time, before the rev counter needle is Ô of the way to the red area of the rev counter. 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 Rshoes Driving Key positions Key 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.

Gearshift recommendation Driving and parking Shifting gears ! Mercedes-AMG vehicles: the automatic transmission does not shift up automatically even when the engine limiting speed for the current gear is reached. When the engine limiting speed is reached, the fuel supply is cut to prevent the engine from overrevving. Always make sure that the engine speed does not reach the red area of the rev counter. There is otherwise a risk of engine damage. The gearshift recommendations assist you in adopting an economical driving style. The recommended gear is shown in the multifunction display. X Shift to recommended gear ; according to gearshift recommendation : when shown in the multifunction display. Upshifting (Mercedes-AMG vehicles) ! The automatic transmission does not shift To shift up: pull steering wheel gearshift paddle ;. The automatic transmission shifts up to the next gear. All vehicles (except Mercedes-AMG vehicles): if the maximum engine speed on the currently engaged gear is reached and you continue to accelerate, the automatic transmission automatically shifts up in order to prevent engine damage. X To shift down: pull steering wheel gearshift paddle :. The automatic transmission shifts down to the next gear. Automatic downshifting occurs when coasting. If the engine exceeds the maximum engine speed when shifting down, the automatic transmission protects against engine damage by not shifting down. X up automatically even when the engine limiting speed for the current gear is reached. When the engine limiting speed is reached, the fuel supply is cut to prevent the engine from overrevving. Always make sure that the engine speed does not reach the red area of the rev counter. There is otherwise a risk of engine damage. Before the engine speed reaches the red area, an upshift indicator will be shown in the multifunction display.

Driving tips General notes 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. Z 195 Driving and parking Driving tips 196 Driving tips Drive sensibly – save fuel Observe the following tips to save fuel: Driving and parking RThe tyres should always be inflated to the recommended tyre pressure. RRemove unnecessary loads. RRemove roof racks when they are not needed. RWarm up the engine at low engine speeds. RAvoid frequent acceleration or braking. RHave all maintenance work carried out as indicated by the service intervals in the Service Booklet or by the service interval display. 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 provides feedback on how economical your driving characteristics are. The ECO display assists you in achieving the most economical driving style for the selected settings and prevailing conditions. Consumption can be significantly influenced by your driving style. The ECO display consists of three bars: RAcceleration RConstant RCoasting The percentage count is the mean value of the three bar values. The three bars and the mean value begin at the value of 50%. A higher percentage count indicates a more economical driving style. The ECO display does not indicate the actual fuel consumption. A fixed percentage count in the ECO display does not indicate a fixed consumption. In addition to driving style, the consumption is affected by many other factors, such as: Rload Rtyre pressure start Rchoice of route Rthe use of electrical consumers These factors are not included in the ECO display. The evaluation of your driving style takes the following three categories into consideration: RAcceleration (evaluation of all acceleration processes): - the bar fills up: moderate acceleration, especially at higher speeds - the bar empties: sporty acceleration RConstant (assessment of driving behaviour at all times:) - the bar fills up: constant speed and avoidance of unnecessary acceleration and deceleration - the bar empties: fluctuations in speed RCoasting (assessment of all deceleration processes): - the bar fills up: anticipatory driving, keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes. - the bar empties: frequent braking An economical driving style involves driving at a moderate engine speed. To achieve a higher value in the categories Acceleration and Constant Constant: Robserve the gearshift recommendation Rdrive the vehicle in drive program C or E (vehicles with DYNAMIC SELECT button). On long journeys at a constant speed, e.g. on the motorway, only the bar for Constant will change. The ECO display summarises the driving characteristics from the start of the journey to its Rcold Driving tips 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. For vehicles with automatic transmission, you need to activate manual gearshifting (Y page 185). This also applies if you have activated cruise control, SPEEDTRONIC or DISTRONIC PLUS. This will use the braking effect of the engine, so less braking will be required to maintain vehicle speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Briefly depressing the accelerator pedal on downhill gradients while the manual drive program M is temporarily activated (vehicles with automatic transmission): the automatic transmission may switch back to the last active automatic drive program E or S. The automatic transmission may shift to a higher gear. This can reduce the engine's braking effect. 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. If the brakes have been used only moderately, you should occasionally test their effectiveness. To do this, brake more firmly from a higher speed, paying attention to 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. Z Driving and parking completion. Therefore, there are dynamic changes in the bars at the start of a journey. During a prolonged driving time, these changes are smaller. For more dynamic changes, perform a manual reset. Further information on the ECO display (Y page 250). 197 Driving and parking 198 Driving tips This can increase the braking distance considerably. RIn order to prevent any salt build-up, apply the brakes occasionally while paying attention to the traffic conditions. RCarefully depress the brake pedal at the end of the journey and when starting the next journey. RMaintain a much greater distance to the vehicle in front. New brake pads/linings Brake pads/linings and discs that are either new or have been replaced only achieve optimum braking effect after several hundred kilometres of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal. For safety reasons, Mercedes-Benz recommends that you only have brake pads/linings fitted to your vehicle which have been approved for Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles or which are not of an equivalent quality could affect your vehicle's operating safety. Driving on wet roads Aquaplaning If water has accumulated to a certain depth on the road surface, there is a danger of aquaplaning occurring, even if: Ryou are driving at low speeds tyres have adequate tread depth For this reason, drive in the following manner in the event of heavy rain or in conditions in which aquaplaning can occur: Rthe Rlower your speed Ravoid tyre ruts Ravoid sudden steering movements Rbrake 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: Rin the case of standing water, the water level must be no higher than 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. You should pay special attention to road conditions when temperatures are around freezing point.

Driving systems 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. The speed indicated in the speedometer may differ slightly from the speed stored. Important safety notes If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. Cruise control cannot take into account road, weather or traffic conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time, and for staying in lane. Do not use cruise control: Rin road and traffic conditions which do not allow you to maintain a constant speed, e.g. in heavy traffic or on winding roads Ron smooth or slippery roads. Braking or accelerating can cause the drive wheels to lose traction and the vehicle could then skid Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow If there is a change of drivers, advise the new driver of the speed stored. Cruise control General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. You must select a lower gear in good time on long and steep downhill gradients, especially if the vehicle is laden or towing a trailer. For vehicles with automatic transmission, you need to have selected manual shift drive program M (Y page 185).

Variable SPEEDTRONIC is selected. 203 204 Driving systems Driving and parking Permanent SPEEDTRONIC You can use the on-board computer to limit the speed permanently to a value between 160 km/h(e.g. for driving on winter tyres) and the maximum speed (Y page 259). Shortly before the stored speed is reached, it appears in the multifunction display. Permanent SPEEDTRONIC remains active even if variable SPEEDTRONIC is deactivated. You cannot exceed the stored limit speed even if you depress the accelerator pedal beyond the pressure point (kickdown). 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 to avoid exceeding the set speed or to maintain the designated distance from the vehicle in front. 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. stop- ped or parked vehicles and crossing traffic As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Roncoming G WARNING DISTRONIC PLUS cannot always clearly 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. ! When DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automatically in certain situations. Driving systems Rwhen towing away Rin a car wash If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of an accident nor override the laws of physics. DISTRONIC PLUS cannot take road and weather conditions or traffic conditions into account. DISTRONIC PLUS is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Do not use DISTRONIC PLUS: Rin road and traffic conditions which do not allow you to maintain a constant speed, e.g. in heavy traffic or on winding roads Ron smooth or slippery roads. Braking or accelerating can cause the drive wheels to lose traction and the vehicle could then skid. Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. In particular, the detection of obstacles can be impaired in the case of: Rdirt on the sensors or obscured sensors or heavy rain Rinterference by other radar sources Rthe possibility of strong radar reflections, for example, in multi-storey car parks If DISTRONIC PLUS no longer detects a vehicle in front, it may unexpectedly accelerate to the speed stored. This speed can: Rsnow Rbe too high for a filter lane or a slip road Rbe so high in the right lane that you pass vehicles driving on the left Rbe so high in the left lane that you pass vehicles driving on the right If there is a change of drivers, advise the new driver of the speed stored.

Activating DISTRONIC PLUS Activation conditions To activate DISTRONIC PLUS, all of the following activation conditions must be fulfilled: Rthe engine must be running. It may take up to two minutes of driving before DISTRONIC PLUS is ready for use. Rthe electric parking brake must be released. RESP® must be switched on, but not intervening. RActive Parking Assist must not be activated. Rthe transmission must be in position D. Rthe driver's door must be closed when you shift from P to D or your seat belt must be fastened. Rthe front-passenger door and the rear doors must be closed. Rthe DISTRONIC PLUS function must be selected with the cruise control lever (Y page 205). Activating X Briefly pull the cruise control lever towards you ?, up : or down A. DISTRONIC PLUS is activated. X Keep the cruise control lever pressed up : or down A until the desired speed is set. X Remove your foot from the accelerator pedal. Your vehicle adapts its speed to that of the vehicle in front, but only up to the desired stored speed. i If you do not fully release the accelerator pedal, the DISTRONIC PLUS inactive message appears in the multifunction display. The set distance to a slower-moving vehicle in front will then not be maintained. The position of the accelerator pedal will determine the speed. You can also activate DISTRONIC PLUS when stationary. The lowest speed that can be set is 30 km/h. Driving with DISTRONIC PLUS Pulling away and driving The vehicle can also pull away when it is facing an unidentified obstacle or is driving on a different line from another vehicle. The vehicle then brakes automatically. Be ready to brake at all times. DISTRONIC PLUS is deactivated when you depress the brake, except when the vehicle is stationary. X If you want to pull away with DISTRONIC PLUS: remove your foot from the brake pedal. X Briefly pull the cruise control lever towards you ?. or X Accelerate briefly. Your vehicle pulls away and adapts its speed to that of the vehicle in front. If no vehicle is detected in front, your vehicle accelerates to the set speed. 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. The vehicle is only accelerated up to the speed you have stored. Driving systems Changing lanes If you change to the overtaking lane, DISTRONIC PLUS supports you if: Ryou are driving faster than 70 km/h PLUS is maintaining the distance to a vehicle in front Ryou switch on the respective turn signal RDISTRONIC PLUS does not detect a danger of collision If these conditions are met, your vehicle is accelerated. Acceleration will be interrupted if changing lanes takes too long or if the distance between your vehicle and the vehicle in front becomes too small. RDISTRONIC Stopping G WARNING When leaving the vehicle, even if it is braked only by DISTRONIC PLUS, it could roll away if: Rthere is a malfunction in the system or in the voltage supply. RDISTRONIC PLUS has been deactivated with the cruise control lever, e.g. by a vehicle occupant or from outside the vehicle. Rthe electrical system in the engine compartment, the battery or the fuses have been tampered with. Rthe battery is disconnected. Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant. There is a risk of an accident. If you wish to exit the vehicle, always turn off DISTRONIC PLUS and secure the vehicle against rolling away. Further information on deactivating DISTRONIC PLUS (Y page 209). If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. Once your vehicle is stationary, it remains stationary and you do not need to depress the brake. i After a short period, the vehicle is secured by the electric parking brake, thus relieving the service brake. i Depending on the specified minimum dis- tance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. When DISTRONIC PLUS is activated, the transmission is shifted automatically to position P if: Rthe driver's seat belt is not fastened 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 The electric parking brake secures the vehicle automatically if DISTRONIC PLUS is activated when the vehicle is stationary and: Ra system fault occurs power supply is insufficient If a malfunction in the electric parking brake occurs, then the transmission may also be shifted into position P automatically. Rthe Z Driving and parking Selecting the drive program DISTRONIC PLUS supports a sporty driving style when you select the S+ drive program (Mercedes-AMG vehicles only), S (Y page 183) or the manual drive program (Y page 185). Acceleration behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have selected the E (C in Mercedes-AMG vehicles:) drive program, the vehicle accelerates more gently. This setting is recommended in stop-start traffic. 207 208 Driving systems Driving and parking 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 maintains to the vehicle in front, dependent on vehicle speed.

Observe the instructions for towing the vehicle with all wheels in full contact with the ground. Z Driving and parking The RACE START active message appears in the multifunction display. 215 Driving and parking 216 Driving systems 4MATIC, together with ESP®, 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 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 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. 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. Chassis with adaptive adjustable damping General notes A suspension with the Adaptive Damping System provides improved driving comfort and continuously controls the calibration of the dampers. The damping characteristics adapt to the current operating and driving situation. The damping is tuned individually to each wheel and depends on: Ryour driving style, e.g. sporty road surface conditions Rthe drive program selected Rthe vehicle level setting The drive program can be set using the DYNAMIC SELECT button (Y page 174).

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 when you: Rswitch on the ignition to position D, R or N on vehicles with automatic transmission Rrelease the electric parking brake 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. Rshift : Example: sensors in the front bumper, left-hand side The sensors must be free of dirt, ice and slush. Otherwise, they may not function correctly. Clean the sensors regularly, taking care not to scratch or damage them (Y page 344). Range Range of the sensors General notes PARKTRONIC does not take into account obstacles located: Rbelow the detection range, e.g. persons, animals or objects Rabove the detection range, e.g. overhanging loads, tail sections or loading ramps of goods vehicles Front sensors Centre Approx. 100 cm Corners Approx. 60 cm Z 217 Driving and parking Driving systems 218 Driving systems Driving and parking Rear sensors Centre Approx. 120 cm Corners Approx. 80 cm Minimum distance Centre Approx. 20 cm Corners Approx. 20 cm If there is an obstacle within this range, the relevant warning displays light up and a warning tone sounds. If the distance falls below the minimum, the distance may no longer be shown. Warning displays : Segments on the left-hand side of the vehicle ; Segments on the right-hand side of the vehicle = Segments showing operational readiness The warning displays show the distance between the sensors and the obstacle. The warning display for the front area is located on the dashboard above the centre air vents. The warning display for the rear area is located on the roof lining in the rear compartment. The warning display for each side of the vehicle is divided into five yellow and two red segments. PARKTRONIC is operational if yellow segments showing operational readiness = light up. The gear lever position or the transmission position of the automatic transmission and the direction in which the vehicle is rolling determine which warning display is active when the engine is running. Manual transmission: Gear lever position Warning display Forward gear or Neutral Front area activated Reverse gear or Rear and front areas the vehicle is rolling activated backwards Automatic transmission: Transmission position Warning display D Front area activated R, N or the vehicle is rolling backwards Rear and front areas activated P No areas activated One or more segments light up as the vehicle approaches an obstacle, depending on the vehicle's distance from the obstacle. From the: Rsixth segment onwards, you will hear an intermittent warning tone for approximately two seconds. Rseventh segment onwards, you will hear a warning tone for approximately two seconds. This indicates that you have now reached the minimum distance. Driving systems 219 Driving and parking Deactivating/activating PARKTRONIC : Indicator lamp ; To deactivate/activate PARKTRONIC If indicator lamp : lights up, PARKTRONIC is deactivated. i PARKTRONIC is automatically activated when you turn the key to position 2 in the ignition lock.

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 216). i The active braking application is only available on vehicles with automatic transmission. 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 deactivated, Active Parking Assist is also unavailable. 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 sharp angle. Otherwise, you may damage the wheels or tyres. Driving systems 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 218) 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 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 Ron between your vehicle and the trailer, Active Parking Assist is no longer available. PARKTRONIC is deactivated for the rear area. 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 deactivate Active Parking Assist. Rthe For further information on the detection range (Y page 217). 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 Z Driving and parking Active Parking Assist may also display spaces not suitable for parking, e.g.: 221 Driving and parking 222 Driving systems Example: parking symbol : 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 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: When 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 driver's side is activated. When parking on the driver's side, this must remain activated until you confirm the use of Active Parking Assist Stop the vehicle when the parking symbol shows the desired parking space in the instrument cluster.

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 Online. You can select a service station and navigation to this service station will then begin. This function can be activated and deactivated in COMAND Online. 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 multifunction camera : attached at 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. The display can also be updated without a visible traffic sign if: 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 Z 231 Driving and parking Driving systems Driving and parking 232 Driving systems If a sign indicating the end of a restriction (speed limit or overtaking restriction) is passed, the sign is displayed for five seconds. The currently applicable traffic regulation continues to be shown in the assistance graphic display (Y page 255). 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. The system may be either functionally impaired or temporarily unavailable if: Rvisibility is poor, e.g. due to snow, rain, fog or spray Rthere is glare, e.g. from the sun being low in the sky Rthere is dirt, ice or misting on the windscreen in the vicinity of the camera Rtraffic signs are hard to detect (dirt, ice, snow) Rthe traffic signs are insufficiently lit at night Rsigns are ambiguous (e.g. traffic signs on construction sites or in adjacent lanes) Rthe information in the digital street map of the navigation system is incorrect or out of date Activating Traffic Sign Assist X Activate the Traffic Sign Assist display using the on-board computer (Y page 256). If you have activated the Traffic Sign Assist display in the on-board computer, the traffic regulations (speed limits and overtaking restrictions) are displayed in the instrument cluster for five seconds respectively. The wrong-way warning and the traffic sign display for speed limits and overtaking restrictions remain active in the Assist graphic even when the display has been deactivated. Traffic Sign Assist is not available in all countries. In this case, display : is shown in the multifunction display.

Important safety notes G WARNING Blind Spot Assist does not react to vehicles: Rovertaken No entry (wrong-way warning) A warning message : is displayed in the instrument cluster if Traffic Sign Assist detects that you are passing a “no entry” sign and you are driving in the wrong direction. 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 234) and Lane Keeping Assist (Y page 236). 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. Monitoring range of the sensors In particular, the detection of obstacles can be impaired in the case of: Rdirt on the sensors or obscured sensors Rpoor visibility, e.g. due to fog, heavy rain or snow narrow vehicle travelling in front, e.g. a motorcycle or a bicycle Rvery wide lanes Rnarrow lanes Rvehicles not driving in the middle of their lane Rbarriers or other road boundaries Ra Driving systems Warning display : Warning display Blind Spot Assist monitors the area up to 3.0 m behind your vehicle and directly next to your vehicle, as shown in the picture. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if the vehicles are driving on the inner side of their lane. Due to the nature of the system: Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders Rwarnings may be interrupted when driving alongside particularly long vehicles, for example lorries, for a prolonged time Blind Spot Assist is not active at speeds below approximately 30 km/h. Vehicles in the monitoring range are then not indicated. If Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow up to a speed of 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 30 km/h, warning lamp : on the corresponding side lights up red. This warning always occurs when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 12 km/h. The yellow indicator lamp goes out if reverse gear is engaged. Blind Spot Assist is then deactivated. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the corresponding turn signal, a double warning tone sounds. Red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Z Driving and parking Vehicles in the monitoring range are then not indicated. 235 Driving and parking 236 Driving systems Activating Blind Spot Assist X Make sure that Blind Spot Assist is activated in the on-board computer (Y page 257). X Turn the key to position 2 in the ignition lock. Warning lamps : in the exterior mirrors light up red for approximately 1.5 seconds and then turn yellow. Towing a trailer If you couple up a trailer, make sure that you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. Blind Spot Assist is then deactivated. The indicator lamps in the exterior mirrors light up yellow and the Blind Spot Assist not available when towing a trailer See Owner's Manual message appears in the multifunction display. i You can deactivate the indicator lamps in the exterior mirrors. To do so, you will need to deactivate Blind Spot Assist if: Rthe key is in position 2 in the ignition lock Rthe engine is not running electrical connection to the trailer has been established Rthe Lane Keeping Assist General notes Lane Keeping Assist monitors the area in front of your vehicle by means of multifunc- tion camera : attached at the top of the windscreen. Lane Keeping Assist detects lane markings on the road and can warn you before you leave your lane unintentionally. This function is available in a speed range between 60 km/h and 200 km/h. A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration through the steering wheel for up to 1.5 seconds. Important safety notes G WARNING Lane Keeping Assist cannot always clearly identify lane markings. In these cases, Lane Keeping Assist may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay particular attention to the traffic situation and keep in lane, especially if Lane Keeping Assist alerts you. Rnot G WARNING The Lane Keeping Assist warning does not return the vehicle to the original lane. There is a risk of an accident. Always steer, apply the brakes or accelerate the vehicle yourself, especially if Lane Keeping Assist alerts you. If you fail to adapt your driving style, Lane Keeping Assist can neither reduce the risk of an accident nor override the laws of physics. Lane Keeping Assist cannot take into account road, weather or traffic conditions. Lane Keeping Assist is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Lane Keeping Assist does not keep your vehicle in its lane. Towing a trailer Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflection from other vehicles (e.g. if the road surface is wet) Rthe windscreen is dirty, misted up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rno or several, unclear lane markings are present for one lane, e.g. in a construction area Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Rthe road is narrow and winding Rthere are highly variable shade conditions on the road Activating Lane Keeping Assist X Activate Lane Keeping Assist using the onboard computer; to do so, select Standard or Adaptive (Y page 257). If you drive at speeds above 60 km/h and lane markings are detected, the lane markings in the assistance graphics display (Y page 255) are shown in green. When Standard is selected, no warning vibration occurs if: Ryou have switched on the turn signal. In this event, the warnings are suppressed for a certain period of time. Ra driving safety system intervenes, such as ABS, BAS or ESP®. When Adaptive is selected, no warning vibration occurs if: Ryou have switched on the turn signal. In this event, the warnings are suppressed for a certain period of time. Ra driving safety system intervenes, such as ABS, BAS or ESP®. Ryou accelerate hard, e.g. kickdown. Ryou brake hard. Ryou steer actively, e.g. swerve to avoid an obstacle or change lane quickly. Ryou cut the corner on a sharp bend. In order that you are warned only when necessary and in good time if you cross the lane marking, the system detects certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a bend Rthe road has very wide lanes, e.g. a motorway Rthe system detects solid lane markings The warning vibration occurs later if: Rthe Ryou road has narrow lanes cut the corner on a bend Towing a trailer Important safety notes 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 Z Driving and parking The system may be impaired or may not function if: 237 238 Towing a trailer Driving and parking 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 trailer Rthe ball coupling Rtrailer 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: Rthe 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 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. Ron 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 412). 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. 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: RMercedes‑AMG CLA 45 4MATIC with AMG Line When towing a trailer, set the tyre pressure on the rear axle of the towing vehicle for the maximum load. Further information on the tyre pressure table in the fuel filler flap (Y page 374). Please note that when towing a trailer, the following driving systems have limited availability or are not available at all. RVehicles RPARKTRONIC (Y page 216) Spot Assist (Y page 234) The height of the ball coupling changes with the load of the vehicle. If necessary, use a trailer with a height-adjustable drawbar. You will find fitting dimensions and loads under "Technical data" (Y page 411). RBlind Driving tips Observe the notes on ESP® trailer stabilisation (Y page 79). 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. 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. For vehicles with automatic transmission, you need to have selected manual drive program M (Y page 185). This also applies if you have activated cruise control, SPEEDTRONIC or DISTRONIC PLUS. This will use the braking effect of the engine, so less braking will be required to maintain vehicle speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If you need additional braking, depress the brake pedal repeatedly rather than continuously. Briefly depressing the accelerator pedal on downhill gradients while the manual drive program M is temporarily activated (vehicles with automatic transmission): the automatic transmission may switch back to the last active automatic drive program E or S. The automatic transmission may shift to a higher gear. This can reduce the engine's braking effect. Driving tips If the trailer swings from side to side: Do not accelerate. Do not countersteer.

You can connect accessories to the per- manent power supply up to a maximum of 240 W. You cannot charge a trailer battery using the power supply. 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. If LED lamps are fitted in the trailer, a malfunction 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 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.

For an overview, see the instrument panel illustration (Y page 32). Displays and operation Instrument cluster lighting The light sensor in the instrument cluster automatically controls the brightness of the multifunction display. In daylight, the displays in the instrument cluster are not illuminated. The lighting in the instrument cluster, in the displays and the controls in the vehicle interior can be adjusted using the brightness control knob. The brightness control knob is located on the bottom left of the instrument cluster (Y page 32). X Turn the brightness control knob clockwise or anti-clockwise. If the light switch is set to the Ã, T or L position, the brightness is dependent upon the brightness of the ambient light. Speedometer with segments The speedometer is divided into segments only on vehicles with DISTRONIC PLUS. The segments in the speedometer indicate which speed range is available. RVariable SPEEDTRONIC activated (Y page 202): The segments light up from the start of the scale to the selected limit speed. RDISTRONIC PLUS activated (Y page 204): One or two segments in the set speed range light up. RDISTRONIC PLUS detects a vehicle in front moving more slowly than the stored speed: The segments between the speed of the vehicle in front and the stored speed light up. Rev counter Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 120 †. At high outside temperatures and when driving uphill, the coolant temperature may rise to the end of the scale. ! Do not drive in the overrevving range. Doing so will damage the engine. The red band in the rev counter indicates the engine's overrevving range. The engine is limited within a range to protect the engine when the red band is reached. Operating the on-board computer Overview Outside temperature display You should pay special attention to road conditions when temperatures are around freezing point.

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. Check wheels and tyres for damage at least once a month. Check wheels and tyres 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 Rpunctures Rtears 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 371). 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 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 374). Rbulges G WARNING 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: Rsummer tyres: 3 mm tyres: 4 mm For safety reasons, replace the tyres before the legally prescribed limit for the minimum tyre tread depth is reached. RM+S Selecting, fitting and replacing tyres G WARNING Exceeding the stated tyre load-bearing capacity and the approved maximum speed could lead to tyre damage or the tyre bursting. There is a risk of accident. Therefore, only use tyre types and sizes approved for your vehicle model. Observe the tyre load rating and speed rating required for your vehicle. Pay special attention to country-specific requirements for tyre approval. These Z Wheels and tyres Notes on the tyre tread Wheels and tyres 372 Winter operation 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 here the "MOExtended tyres (tyres with run-flat characteristics)" section (Y page 352). 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 396). 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 pressure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tyres with a flat tyre (Y page 352). Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified specialist workshop. Winter operation General notes Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 379). Driving with summer tyres At temperatures below +7 †, summer tyres lose elasticity and therefore traction and braking power. Change the tyres on your vehicle to M+S tyres. Using summer tyres at very cold temperatures could cause tears to form, thereby damaging the tyres permanently. Mercedes-Benz cannot accept responsibility for this type of damage. G WARNING Damaged tyres can cause tyre inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tyres regularly for signs of damage and replace any damaged tyres immediately. M+S tyres G WARNING M+S tyres with a tyre tread depth of less than 4 mm are not suitable for use in winter as they do not provide sufficient traction. There is a risk of accident. M+S tyres with a tread depth of less than 4 mm must be replaced. Winter operation Check the tyre pressures (Y page 374). Restart the tyre pressure loss warning system (Y page 376). X Restart the tyre pressure monitor (Y page 378). X X Information about driving with an emergency spare wheel (Y page 396). Snow chains G WARNING If snow chains are fitted to the rear 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 fit snow chains on the rear wheels fit snow chains in pairs to the front wheels. Ralways ! 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. For more information, please contact a qualified specialist workshop. 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 384). 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. Rwhen snow chains are fitted, never use Active Parking Assist (Y page 220). You may wish to deactivate ESP® (Y page 77) when pulling away with snow chains fitted. This way you can allow the wheels to spin in a controlled manner, achieving increased driving force (cutting action). Information about driving with an emergency spare wheel (Y page 396). Z Wheels and tyres 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 204). When you have fitted the M+S tyres: 373 374 Tyre pressure Tyre pressure Tyre pressure specifications G WARNING Underinflated or overinflated tyres pose the following risks: 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. Observe the recommended tyre pressure and check the tyre pressure of all the tyres including the spare wheel: Wheels and tyres Rthe Rat least every two weeks the load changes Rbefore embarking on a longer journey Rfor changed operating conditions, e.g. offroad driving If necessary, correct the tyre pressure. 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. G WARNING If the tyre pressure drops repeatedly, the wheel, valve or tyre may be damaged. Tyre pressure that is too low may result in a tyre blow-out. There is a risk of accident. RCheck the tyre for foreign objects. RCheck whether the wheel is losing air or the valve is leaking. If you are unable to rectify the damage, contact a qualified specialist workshop. H Environmental note Check the tyre pressure regularly, at least every 14 days. The recommended tyre pressures for various operating conditions can be found in the tyre pressure table on the fuel filler flap (Y page 189). Operation with an emergency spare wheel: information on operation with an emergency spare wheel can be found in the general notes in the "Emergency spare wheel" section (Y page 396). Operation with a trailer: the applicable value for the rear axle is the maximum tyre pressure value stated in the table inside the fuel filler flap. Additionally, the tyre pressure table may also 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 table apply for all tyres approved for this vehicle. If a tyre size precedes a tyre pressure, the following tyre pressure information is only valid for that tyre size. Use a suitable pressure gauge to check the tyre pressure. The outer appearance of a tyre 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 vehicle speed 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 Tyre pressure loss warning system General notes While the vehicle is in motion, the tyre pressure loss warning system monitors the set tyre pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tyre. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display. You can recognise the tyre pressure loss warning by the Run Flat Indicator active Restart with OK message which appears in the multifunction display in the Serv.menu. Information on the message disServ. play can be found in the "Restarting the tyre pressure loss warning system" section (Y page 376). 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 374). The tyre pressure loss warning does not replace the need to regularly check the tyre pressures. An even loss of pressure on several tyres at the same time cannot be detected by the tyre pressure loss warning system. The tyre pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tyre is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering manoeuvres. The function of the tyre pressure loss warning system is limited or delayed if: Rsnow chains are fitted to your vehicle's tyres. Rroad conditions are wintry. Ryou are driving on sand or gravel. Ryou adopt a very sporty driving style (cornering at high speeds or driving with high rates of acceleration). Ryou are towing a very heavy or large trailer. Ryou are driving with a heavy load (in the vehicle or on the roof). Z Wheels and tyres 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: 375 Tyre pressure 376 Restarting the tyre pressure loss warning system If you wish to cancel the restart: Restart the tyre pressure loss warning system if you have: or Wheels and tyres Rchanged the tyre pressure Rchanged the wheels or tyres Rfitted new wheels or tyres X Before restarting, make sure that the tyre pressures are set properly on all four tyres for the respective operating conditions. The recommended tyre pressures can be found in the tyre pressure table on the fuel filler flap. The tyre pressure loss warning system can only give reliable warnings if you have set the correct tyre pressure. If an incorrect tyre pressure is set, these incorrect values will be monitored.

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 374). Note that the correct tyre pressure for the current operating situation must first be taught-in to the tyre pressure monitor. Tyre pressure Rif the warning lamp is lit continuously, the tyre pressure on one or more tyres is significantly too low. The tyre pressure monitor is not malfunctioning. Rif the warning lamp flashes for around a minute and then remains lit constantly, the tyre pressure monitor is malfunctioning. In addition to the warning lamp, a message appears in the multifunction display. Observe the information on display messages (Y page 292). It may take up to ten minutes for a malfunction of the tyre pressure monitor to be indicated. A malfunction will be indicated by the tyre pressure warning lamp 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 meas- ured 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 in the ignition lock (Y page 165). X Press = or ; on the steering wheel to select the Serv. Serv.menu.

X If the vehicle was parked for longer than 20 minutes, the Tyre pressures will be displayed after a few minutes of driving message is shown. After a teach-in period, the tyre pressure monitor automatically detects new wheels or new sensors. As long as a clear allocation of the tyre pressure values to the individual wheels is not possible, the Tyre pressure monitor active message is shown instead of the tyre pressure display. The tyre pressures are already being monitored. If an emergency spare wheel is fitted, for a few minutes the system may continue to show the tyre pressure of the wheel that has been removed. If this occurs, note that the value displayed for the position where the spare wheel is fitted is not the same as the current tyre pressure of the emergency spare wheel. Z Wheels and tyres 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 378). 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 374). 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: 377 378 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. The yellow tyre pressure warning lamp then lights up. Wheels and tyres RIf the Please correct tyre pressure message appears in the multifunction display, the tyre pressure in at least one tyre is too low. The tyre pressure must be corrected when the opportunity arises. RIf the Tyre pressure Check tyre(s) message appears in the multifunction display, the tyre pressure in one or more tyres has dropped significantly. The tyres must be checked. RIf the Tyre pressure Caution Tyre malfunction message appears in the multifunction display, the tyre pressure in one or more tyres has dropped suddenly. The tyres must be checked. Observe the instructions and safety notes in the display messages in the "Tyres" section (Y page 292). 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 set reference values manually as described here. The tyre pressure monitor then monitors the new tyre pressure values. 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.

Vehicles with an emergency spare wheel: in the event of a flat tyre, the emergency spare wheel is fitted according to the description under "Fitting a wheel" (Y page 380). Interchanging the wheels G WARNING Interchanging the front and rear wheels may severely impair the driving characteristics if the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of accident. Interchange front and rear wheels only if the wheels and tyres are of the same dimensions. ! On vehicles fitted with a tyre pressure monitor, electronic components are located in the wheel. Tyre-fitting tools should not be applied in the area of the valve, as this could damage the electronic components. Only have tyres changed at a qualified specialist workshop. Z Wheels and tyres Radio type approval for the tyre pressure monitor 379 Changing a wheel Wheels and tyres 380 Interchanging the front and rear wheels of differing dimensions can render the general operating permit invalid. Observe the instructions and safety notes in the "Changing a wheel" section (Y page 379). 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 or the tyre pressure monitor. Direction of rotation Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aquaplaning. These advantages can only be gained if the tyres are fitted corresponding to the direction of rotation. 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. Move the front wheels to the straightahead position. X Vehicles with manual transmission: depress the clutch pedal fully and engage first or reverse gear.

Further information on tyre pressure (Y page 374). Check tyre pressures regularly and only when the tyres are cold. Notes on the vehicle equipment – always fit the vehicle: Wheels and tyres RFA: Rwith tyres of the same size across an 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 352). 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.

To prevent hazardous situations: RAdapt your driving style accordingly and drive carefully. RNever fit more than one spare wheel/emergency spare wheel if the dimensions are different to those of the wheel being replaced. ROnly use a spare wheel/emergency spare wheel briefly if the dimensions are different to those of the wheel being replaced. not switch off ESP®.

RDo 7 8 When using an emergency spare wheel or spare wheel of a different size, you must not exceed the maximum speed of 80 km/h. Snow chains must not be fitted to emergency spare wheels. General notes Apart from some country-specific variants, vehicles are not equipped with an emergency spare wheel. Emergency spare wheels are specific to the vehicle. For more information on which emergency spare wheels are approved for your vehicle, consult a qualified specialist workshop. You should regularly check the pressure of the emergency spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 374). The value on the wheel is valid. In addition, the emergency spare wheel tyre pressure can be found under "Technical data" (Y page 398). An emergency spare wheel may also be fitted against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel. Replace the tyres after six years at the latest, regardless of wear. This also applies to the emergency spare wheel. Use of snow chains not permitted. Observe the notes in the "Snow chains" section. Observe the notes on "Large wheels" in the "Wheel/tyre combinations" section. Emergency spare wheel 397 If you are driving with the emergency spare wheel fitted, the tyre pressure loss warning system or the tyre pressure monitor cannot function reliably. Only restart the tyre pressure loss warning system or tyre pressure monitor when the defective wheel has been replaced with a new wheel. Vehicles with tyre pressure monitor: after fitting an emergency spare wheel, the system may still display the tyre pressure of the removed wheel for a few minutes. The value displayed for the position where the emergency spare wheel is fitted is not the same as the current tyre pressure of the emergency spare wheel.

Even small amounts of the wrong fuel can result in damage to the fuel system and the engine. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely. Technical data ! Only refuel using unleaded petrol with at least 95 RON that conforms to the European standard EN 228 or E DIN 51626-1 or an equivalent specification. Fuel of this specification may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle using E10 fuel. Fuel that does not conform to EN 228 or E DIN 51626–1 can lead to increased wear as well as damage to the engine and exhaust system. i E10 fuel contains up to 10% bioethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle using E10 fuel. ! Only use the fuel recommended. Operat- ing the vehicle with other fuels can lead to engine failure. ! Do not use the following: RE85 (petrol with 85% ethanol) RE100 (100% ethanol) RM15 (petrol with 15% methanol) RM30 (petrol with 30% methanol) RM85 (petrol with 85% methanol) (100% methanol) RPetrol with additives containing metal RDiesel Do not mix such fuels with the fuel recommended for your vehicle. RM100 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. CLA 200, CLA 250, CLA 250 4MATIC: as a temporary measure, if the recommended fuel is not available, you may also use regular unleaded petrol with an octane rating of 93 RON. All other models: as a temporary measure, if the recommended fuel is not available, you may also use regular unleaded petrol with an octane rating of 91 RON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration. Never refuel using fuel with a lower RON. i In some countries, the available petrol may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced. Information on refuelling (Y page 189). Mercedes-AMG vehicles ! Only refuel using super unleaded petrol with at least 98 RON, that conforms to the European standard EN 228 or E DIN 51626-1 or an equivalent specification. You can otherwise impair engine output or damage the engine. Fuel of this specification may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle using E10 fuel. ! As a temporary measure, if the recom- mended fuel is not available, you may also Service products and capacities ! As a temporary measure, if the recom- mended fuel is not available, you may also use unleaded petrol in emergencies with an octane rating of 91 RON. Doing so results in noticeably higher fuel consumption, and the engine power output is noticeably reduced. Avoid driving at full throttle. If no fuel other than petrol with 91 RON or a lower grade is available, you should have the vehicle adapted to run on this fuel at a qualified specialist workshop. CLA 250 (only for certain countries). ! Only refuel using unleaded, sulphur-free unleaded petrol with at least 95 RON/ 85 MON that conforms to European standard EN 228 or an equivalent specification. You could otherwise impair engine output or damage the emission control system. i In some countries, the available petrol may not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours, especially on short journeys. As soon as sulphur-free fuel (sulphur content < 10 ppm) is used for refuelling, the odours are reduced. Additives ! Operating the engine with fuel additives added later can lead to engine failure. Do not mix fuel additives with fuel. This does not include additives for the removal and prevention of residue build-up. Petrol must only be mixed with additives recommended by Mercedes-Benz. Observe the instructions for use in the product description. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre. Mercedes-Benz recommends that you use fuel brands that have additives. The quality of the fuel available in some countries may not be sufficient. Residue could build up in the injection system as a result. In this case, in consultation with a MercedesBenz Service Centre, the petrol may be mixed with the cleaning additive recommended by Mercedes-Benz. Always observe the notes and mixing ratios specified on the container. Diesel Fuel grade G WARNING If you mix diesel fuel with petrol, the flash point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running, components in the exhaust system may overheat unnoticed. There is a risk of fire. Never refuel with petrol. Never add petrol to diesel fuel. ! When refuelling, only use diesel fuel that conforms to the European standard EN 590 or is of equivalent quality. Fuel that does not conform to EN 590 can lead to increased wear as well as damage to the engine and exhaust system. ! Do not use the following: Rmarine diesel oil Rbio-diesel Rvegetable oil Rpetrol Rparaffin Rkerosene Do not mix such fuels with diesel fuel and do not use any special additives. Otherwise, engine damage may occur. Rheating ! Vehicles with diesel particle filters: in countries outside the EU, only use low sulphur Euro diesel with a sulphur content of Z Technical data use unleaded petrol with an octane rating of 95 RON. This may reduce engine performance and increase fuel consumption. As much as possible, avoid driving at full throttle. 405 406 Service products and capacities under 50 ppm. Otherwise, the emission control system could be damaged. ! Vehicles without a diesel particle fil- ter: in countries where only diesel fuel with a high sulphur content is available, you will need to carry out your vehicle's oil change at shorter intervals. More information about the interval for oil change can be obtained from any qualified specialist workshop. 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 189). 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 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. Rdriving The vehicle will use more fuel than usual in the following situations: Rat very low outside temperatures Rin urban traffic Ron short journeys Rin mountainous terrain Rwhen towing a trailer i Only for certain countries: you can find the current consumption and emissions 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.

Engine oil viscosity When handling brake fluid, observe the important safety notes on service products (Y page 402). The brake fluid change intervals can be found in the Service Booklet. Only use brake fluid approved by MercedesBenz according to MB-Freigabe or MBApproval 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. Technical data i Have the brake fluid regularly replaced at 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. 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 Brake fluid G WARNING The brake fluid continuously absorbs moisture from the air. This results in the boiling point of the brake fluid lowering. If the boiling point of the brake fluid is too low, vapour pockets may form when the brakes are subjected to a heavy load. This would impair braking efficiency. There is a risk of an accident. Have the brake fluid renewed at the prescribed intervals. 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.
