The objectives are for the natural resources which form the basis of our existence on this planet to be used sparingly and in a manner which takes the requirements of both nature and humanity into account. You too can help to protect the environment by operating your vehicle in an environmentally responsible manner. Fuel consumption and the rate of engine, transmission, brake and tyre wear depend on the following factors: Roperating conditions of your vehicle personal driving style You can influence both factors. You should bear the following in mind: Operating conditions: Ryour Ravoid short trips as these increase fuel con- sumption. sure that the tyre pressures are always correct. Rdo not carry any unnecessary weight. Rkeep an eye on the vehicle's fuel consumption. Rremove roof racks once you no longer need them. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Ralways have maintenance work carried out at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. Personal driving style: Rmake Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine with the vehicle stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. frequent, sudden acceleration. Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. Ravoid Rswitch off the engine in stationary traffic. Returning end-of-life vehicles Mercedes-Benz will take back your Mercedes-Benz to dispose of it in an environmentally responsible manner, in accordance with the European Union (EU) End of Life Vehicles Directive. The End of Life Vehicles Directive applies to vehicles with a gross vehicle weight of up to 3.5 t, in accordance with national regulations. For several years, Mercedes-Benz has been meeting all the legal requirements for a design which allows for recycling and reuse. There is a network of return points and disassembly plants which can recycle your vehicle in an environmentally responsible manner. The options for recycling vehicles and parts are constantly being developed and improved. This means that your MercedesBenz will also continue to meet even the increased recycling quotas in the future in good time. You can obtain further information from your national Mercedes-Benz homepage or your national hotline number. Vehicle equipment This Owner's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Owner's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelevant systems and functions. The equipment in your vehicle may therefore differ from that shown in the descriptions and illustrations. All the systems found in your vehicle Z 25 26 Introduction are listed in the original purchase agreement of your vehicle. Should you have any questions concerning equipment and operation, please consult a Mercedes-Benz Service Centre. Operating safety Safety notes G WARNING All work on the vehicle and, in particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. The specialist workshop must have the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. G WARNING Some safety systems only function when the engine is running. You should therefore never switch off the engine when driving. Otherwise, the safety systems of your vehicle may not function correctly and as a result will no longer protect you and other persons as intended. In addition, there is a risk that you may lose control of your vehicle and thus cause an accident. G WARNING Work carried out incorrectly, or alterations made to the vehicle, e.g. re-routing of cables under coverings, could cause the safety systems of your vehicle to stop working properly. The safety systems would thus no longer protect you and other persons as intended. In addition, there is a risk that you may lose control of your vehicle and thus cause an accident. All work and alterations to the vehicle, e.g. installations or modifications, should therefore be carried out at a qualified specialist workshop. G WARNING If work on electronic equipment and its software is carried out incorrectly, this equipment could stop working. The electronic systems are networked via interfaces. Tampering with these electronic systems could cause malfunctions in systems which have not been modified. Malfunctions such as these can seriously jeopardise the vehicle's operating safety and therefore your own safety. You should therefore have all work and modifications to electronic components carried out at a qualified specialist workshop. Qualified specialist workshop A qualified specialist workshop has the necessary specialist knowledge, tools and qualifications to correctly carry out the work required on your vehicle. This is especially the case for work relevant to safety. Observe the information in the Service Booklet. Always have the following work carried out at a qualified specialist workshop: Rwork relevant to safety and maintenance work Rrepair work Ralterations, installation work and modifications Rwork on electronic components Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre. Rservice Vehicle registration Mercedes-Benz may ask its Service Centres to carry out technical inspections on certain vehicles to improve their quality or safety. If you did not purchase your vehicle from an authorised specialist dealer and your vehicle has never been inspected at a MercedesBenz Service Centre, it is possible that your vehicle is not registered in your name with Introduction Mercedes-Benz. Mercedes-Benz can only inform you about vehicle checks if it has your registration data. It is advisable to register your vehicle with a Mercedes-Benz Service Centre. Inform Mercedes-Benz as soon as possible about any change in address or vehicle ownership. Data stored in the vehicle Fault data Correct use Components critical for vehicle operation are equipped with fault data memories as standard. There are also data storage devices which record the technical reactions of vehicle components to certain driving situations (e.g. airbag deployment or ESP® intervention). This data is used exclusively to: G WARNING Rassist Various warning stickers are affixed to your vehicle. Their purpose is to draw your attention, and the attention of others, to various dangers. Therefore, do not remove any warning stickers unless the sticker clearly states that you may do so.

Countryspecific deviations are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-relevant systems and functions. i Please read the information on qualified specialist workshops (Y page 26). Occupant safety Important safety notes Seat belts, together with the Supplemental Restraint System – SRS (Y page 45), are complementary, co-ordinated restraint systems. They reduce the risk of injury in specific, pre-defined types of accident situations and thereby increase occupant safety. However, seat belts and airbags generally do not protect against objects penetrating the vehicle from the outside. To ensure that the restraint systems can deliver their full potential protection, make sure that: Rthe seat and head restraint are adjusted properly (Y page 96). Rthe seat belt has been fastened properly (Y page 53). Rthe airbags can inflate unrestricted if deployed (Y page 46). Rthe steering wheel is adjusted properly (Y page 96). Rthe restraint systems have not been modified. i An airbag increases the protection of vehicle occupants wearing a seat belt. As such, they are only an additional restraint system which complements, but does not replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all times, even if the vehicle is equipped with airbags. The airbags are not deployed in all types of accidents. For example, if the protective capacity of correctly fastened seat belts is not increased by deploying the airbags, the airbags will not deploy. Airbag deployment only provides increased protection if the seat belt is worn correctly because: Rthe seat belt helps to keep the vehicle occupant in the best position in relation to the airbag. Rin a head-on collision, for example, the seat belt prevents the vehicle occupant from being propelled towards the point of impact. It can thus reduce the risk of injury. In accidents in which an airbag is deployed, it provides increased protection only if the seat belt is worn correctly. G WARNING If service work is not carried out correctly, the operating safety of your vehicle may be affected. This could cause you to lose control of your vehicle and cause an accident. Moreover, the safety systems may no longer be able to protect you or others as they are designed to do. Always have service work carried out at a qualified specialist workshop. The workshop must have the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. G WARNING G WARNING Modifications to or work performed incorrectly on the following parts can result in the restraint systems not functioning as intended: If SRS is malfunctioning, individual systems may be activated unintentionally or may not be triggered in the event of an accident with a high rate of vehicle deceleration. A malfunction has occurred if: Rthe restraint system, consisting of seat belts and their anchorage points, belt tensioners, belt force limiters and airbags Rthe wiring Rnetworked electronic systems Airbags and belt tensioners could fail to deploy or be triggered in an accident despite the deceleration force being sufficient to trigger the systems, or could be triggered unintentionally. For this reason, never make any modifications to the restraint systems. Therefore, you must not tamper with electronic components or their software. SRS (Supplemental Restraint System) Introduction SRS consists of: Rthe 6 SRS warning lamp Rairbags Rairbag control unit (with crash sensors) tensioners Rbelt force limiters SRS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the effect of the forces to which occupants are subjected during an accident. Rbelt SRS warning lamp SRS functions are checked regularly when you switch on the ignition and when the engine is running. Therefore, malfunctions can be detected in good time. The 6 SRS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. Rthe 6 SRS warning lamp does not light up when the ignition is switched on. Rthe engine is running and the 6 SRS warning lamp does not go out after a few seconds. Rthe engine is running and the 6 SRS warning lamp lights up again. In this case, have SRS checked immediately at a qualified specialist workshop. MercedesBenz recommends that you use a MercedesBenz Service Centre for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Triggering of belt tensioners, belt force limiters and airbags During the first stage of a collision, the airbag control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as: Rduration Rdirection Rmagnitude Based on the evaluation of this data, the airbag control unit pre-emptively triggers the belt tensioners in the first stage. i The front belt tensioners can only be trig- gered if the seat belt tongues on the front seats are correctly engaged in the seat belt buckles. If there is an even higher rate of vehicle deceleration or acceleration in a longitudinal direction, the front airbags are also deployed. Your vehicle has adaptive, two-stage front airbags. The airbag control unit evaluates vehicle deceleration or acceleration in the event Z 45 Safety Occupant safety Safety 46 Occupant safety of a collision. In the first deployment stage, the front airbag is filled with enough propellant gas to reduce the risk of injuries. The front airbag is fully deployed if a second deployment threshold is exceeded within a few milliseconds. The belt tensioner and airbag triggering thresholds are variable and are adapted to the rate of deceleration or acceleration of the vehicle. This process is pre-emptive in nature. The triggering process must take place in good time at the start of the collision. i Airbags are not deployed in all types of accidents. Also, not all airbags are deployed together in an accident. The different airbag systems work independently of each other. How the airbag system works is determined by the severity of the collision detected, especially the vehicle deceleration or acceleration, and the apparent type of accident: Rhead-on collision impact Rrear impact Rside 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, e.g. the bonnet or the wing, without an airbag being deployed. This is the case if only parts which are relatively easily deformed are affec- ted and the rate of deceleration is not high. Conversely, airbags 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. Airbags Important safety notes Airbag deployment slows down and restricts the movement of the vehicle occupant. If the airbags are deployed, you will hear a bang and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard. The 6 SRS warning lamp lights up. The airbag installation locations are identified by the AIRBAG symbol. G WARNING Airbags provide additional protection; they are not, however, a substitute for seat belts. Observe the following notes to reduce the risk of serious or even fatal injury caused by airbag deployment: Rall vehicle occupants – in particular, pregnant women – must wear their seat belt correctly at all times and lean back against the backrest, which should be positioned as close to the vertical as possible. The head restraint must support the back of the head at about eye level. Ralways secure children less than 1.50 m tall and under 12 years of age in suitable child restraint systems. Rall vehicle occupants must select a seat position that is as far away from the airbag as possible. The driver's seat position must allow the vehicle to be driven safely. The driver's chest should be as far away from Occupant safety Rdo not lean on the doors from inside the vehicle. Rmake sure that there are no people, animals or objects between the vehicle occupants and the area where the airbags are deployed. Rdo not place any objects between the seat backrest and the door. Rdo not hang any hard objects, for example, coat hangers, on the grab handles or coat hooks. Rdo not attach accessories, e.g. cup holders, to the doors. It is not possible to rule out a risk of injury being caused by an airbag, due to the high speed at which the airbag must be deployed. G WARNING Airbag functionality can only be assured if the following parts are not covered and no badges or stickers are attached to them: Rpadded steering wheel boss cover below the steering column Rfront-passenger airbag cover Router side of front seat bolsters Rside trim next to the rear seat backrest Rroof frame cover between the front A-pillar and the C-pillar in the rear compartment Rkneebag G WARNING A small amount of powder is released when an airbag is deployed. The powder could cause short-term breathing difficulties in people with asthma or other respiratory problems. In order to prevent breathing difficulties, you should leave the vehicle as soon as it is safe to do so. You can also open the window to allow fresh air to enter the interior. The powder does not constitute a health hazard and does not indicate that there is a fire in the vehicle. Z Safety the centre of the driver's airbag cover as possible. Rmove the front-passenger seat as far back as possible. This is especially important if you have secured a child in a child restraint system on the front-passenger seat. Rvehicle occupants – in particular, children – must not lean their heads into the area of the window in which the sidebag/windowbag is deployed. Rrearward-facing child restraint systems must not be fitted to the front-passenger seat unless the front-passenger airbag has been disabled. On the front-passenger seat, the front-passenger airbag is disabled if a child restraint system with a transponder for automatic child seat recognition is fitted to the front-passenger seat in a vehicle equipped with automatic child seat recognition. The 4 PASSENGER AIRBAG OFF indicator lamp must be continuously lit. If the front-passenger seat of your vehicle does not have automatic child seat recognition, or your rearward-facing child restraint system does not have automatic child seat recognition, children must be secured in a child restraint system on a suitable seat in the rear. If you secure a forward-facing child restraint system to the front-passenger seat, you must move the front-passenger seat as far back as possible. Rmake sure there are no heavy or sharpedged objects in the pockets of clothing. Rdo not lean forwards, e.g. over the cover of the driver's/front-passenger airbag, particularly when the vehicle is in motion. Rdo not put your feet on the dashboard. Ronly hold the steering wheel on the outside. This allows the airbag to be fully deployed. You could be injured if the airbag is deployed and you are holding the inside of the steering wheel. 47 48 Occupant safety Safety G WARNING The airbag parts are hot after the airbag has been deployed. Do not touch them as you could burn yourself. Have the airbags replaced at a qualified specialist workshop. Otherwise, occupants are not protected by the airbags in the event of another accident. Front airbags The front airbags increase protection for the driver's and front-passenger's head and chest. out automatic child seat recognition has been fitted or that a child restraint system with automatic child seat recognition is incorrectly fitted. ! Do not place heavy objects on the front- passenger seat. The system may then detect that the seat is occupied and if there is an accident, the restraint systems on the front-passenger side could be deployed. Have restraint systems that have been triggered replaced. Driver's kneebag i The driver's kneebag is only available in certain countries. The driver's kneebag increases protection of the driver against: Rknee injuries injuries Rlower leg injuries Rthigh Driver's airbag : deploys in front of the steering wheel; front-passenger airbag ; deploys in front of and above the glove compartment. They are deployed: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction Rif the system determines that airbag deployment can offer additional protection to that provided by the seat belt Rif the seat belt is fastened Rindependently of other airbags in the vehicle Front-passenger airbag ; is only activated if the system determines that the frontpassenger seat is occupied. The 4 PASSENGER AIRBAG OFF indicator lamp on the centre console is not lit (Y page 57). This means that a child restraint system with- Driver's kneebag : is always deployed along with the driver's airbag and inflates underneath the steering column. Sidebags G WARNING If you wish to use seat covers, Mercedes-Benz recommends that, for safety reasons, you only use seat covers that have been approved for Mercedes-Benz vehicles. The seat covers must have a special tear seam for sidebags/pelvisbags. Otherwise, the sidebag/pelvisbag cannot deploy correctly and would fail to provide the intended protection in the event of an accident. Appropriate seat covers can be obtained, for example, from a Mercedes-Benz Service Centre. When deployed, the sidebags offer additional protection for the thorax of the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the: Rhead Rneck The seat covers must have a special tear seam for sidebags/pelvisbags. Otherwise, the sidebag/pelvisbag cannot deploy correctly and would fail to provide the intended protection in the event of an accident.

PRE-SAFE® intervenes: Rin emergency braking situations, e.g. if BAS is activated or for vehicles with DISTRONIC PLUS, BAS PLUS intervenes powerfully Rif the radar sensor system detects an imminent danger of collision in certain situations (on vehicles with DISTRONIC PLUS) Rin critical driving situations, e.g. when physical limits are exceed and the vehicle understeers or oversteers severely X Move the backrest or seat back slightly, but only when the vehicle is stationary. The belt pretensioning is reduced and the locking mechanism is released. G WARNING When adjusting the seat, make sure that nobody can become trapped. ! Make sure that there are no objects in the footwell or behind the seats when moving the seat back. There is a risk that the seats and/or the objects could be damaged. More information about seat-belt adjustment, a convenience function integrated into PRE-SAFE®, can be found in the "Seat-belt adjustment" section (Y page 53). NECK-PRO head restraints The NECK-PRO head restraints increase protection to the driver's and front passenger's head and neck. To this end, the NECK-PRO head restraints on the driver's and frontpassenger seats are moved forwards and upwards in the event of a rear-end collision of a certain severity. This provides better head support. Occupant safety 51 Only use head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. The use of non-approved head restraint covers may prevent NECK-PRO head restraints from triggering properly. Consequently, the NECK-PRO head restraints cannot provide the intended level of protection. Consult a Mercedes-Benz Service Centre regarding availability. If the NECK-PRO head restraints have been triggered in an accident, reset the NECK-PRO head restraints on the driver’s and frontpassenger seat (Y page 51). Otherwise, the additional protection will not be available in the event of another rear-end collision. You can recognise when NECK-PRO head restraints have been triggered by the fact that they have moved forwards and can no longer be adjusted. Resetting triggered NECK-PRO head restraints Following a rear-end collision, MercedesBenz recommends that you have NECK-PRO head restraints checked at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. i Resetting the NECK-PRO head restraints requires a lot of strength. If you have difficulty resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. Safety G WARNING Tilt the top of the NECK-PRO head restraint cushion forwards in the direction of arrow :. X Push the NECK-PRO head restraint cushion down in the direction of arrow ; as far as it will go. X Firmly push the NECK-PRO head restraint cushion back in the direction of arrow = until the cushion engages. X Repeat this procedure for the second NECK-PRO head restraint. X Seat belts Important safety notes Seat belts are the most effective means of restraining the movement of vehicle occupants in the event of an accident. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior. G WARNING A seat belt which is not worn correctly, or which has not been engaged in the seat belt buckle correctly, cannot perform its intended protective function. Under certain circumstances, this could cause severe or even fatal injuries in the event of an accident. Make sure that all occupants – in particular, pregnant women – wear their seat belt correctly at all times. RThe seat belt must fit snugly on your body and must not be twisted. Therefore, avoid wearing bulky clothing, e.g. a winter coat. Z Safety 52 Occupant safety The shoulder belt section must be routed across the centre of your shoulder – on no account across your neck or under your arm – and pulled tight against your upper body. The lap belt must always pass across your lap as low down as possible, i.e. over your hip joints – not across your abdomen. If necessary, push down the belt strap slightly and then retighten it in the roll-up direction. RDo not route the belt strap across sharp edges or fragile objects, especially if these are located on or in your clothing, e.g. spectacles, pens, keys, etc. The seat belt strap could be damaged and tear in an accident, and you or other vehicle occupants could be injured. ROnly one person should use each seat belt at any one time. Children must never travel sitting on the lap of other occupants. It would not be possible to restrain the child in the event of a sudden change in direction, braking or an accident. This could result in severe or even fatal injuries to the child and other occupants. RPersons less than 1.50 m tall cannot wear the seat belts correctly. For this reason, secure persons less than 1.50 m tall in specially designed, suitable restraint systems. RChildren less than 1.50 m tall or under 12 years of age cannot wear the seat belts properly. Therefore, they should always be secured in a suitable child restraint system on a suitable vehicle seat. You can find more information under "Children in the vehicle" in the "Safety" section of the Owner's Manual. Follow the manufacturer's installation instructions when fitting a child restraint system. RDo not secure any objects with a seat belt if the seat belt is also being used by one of the vehicle's occupants. G WARNING The seat belt does not offer the intended level of protection unless the backrest is almost vertical. Under certain circumstances, this could cause severe or even fatal injuries in the event of an accident. Before starting a journey, make sure that the seat is properly adjusted and that the backrest is almost vertical. G WARNING A dirty or damaged seat belt or a seat belt that has been subjected to a load in an accident or which has been modified no longer offers the intended level of protection. Under certain circumstances, this could cause severe or even fatal injuries in the event of an accident. For this reason, check regularly that the seat belts are not damaged or dirty. Always have damaged seat belts or seat belts that have been subjected to a load in an accident replaced at a qualified specialist workshop. Consult a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. For safety reasons, Mercedes-Benz recommends that you only use seat belts which have been approved by Mercedes-Benz for your vehicle. Occupant safety Seat belt adjustment The seat-belt adjustment function adjusts the driver's and front-passenger seat belt to the upper body of the occupants. The belt strap is tightened slightly when: Ryou Adjust the seat and move the backrest to an almost vertical position (Y page 96). X Pull the seat belt smoothly through belt sash guide :.

Rthe key is in position 2 in the ignition lock and you then engage the belt tongue in the buckle. The seat-belt adjustment will apply a certain tightening force if any slack is detected between the occupant and the seat belt. Do not hold on to the seat belt tightly while it is adjusting. On vehicles with a luxury multifunction steering wheel (12 buttons), you can switch the seat-belt adjustment on and off using the on-board computer (Y page 228). The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. More information about PRE-SAFE® can be found in the "PRE-SAFE® (preventative occupant protection)" section (Y page 50). Releasing seat belts X Press release button ? (Y page 53) and guide belt tongue ; back towards belt sash guide :. i If you have guided the seat belt back, it is turned 180 °. This is necessary in order to guarantee that the seat belt is not twisted and that it is routed correctly when the belt is fastened. ! Make sure that the seat belt is fully rolled up. Otherwise, the seat belt or belt tongue will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Damaged seat belts can no longer fulfil their protective function and must be replaced. Consult a Mercedes-Benz Service Centre. Z Safety Fastening seat belts 53 Safety 54 Occupant safety Belt warning for driver and front passenger You can also cancel the rear seat belt status indicator immediately (Y page 232). The 7 seat belt warning lamp in the instrument cluster is a reminder for all occupants to fasten their seat belts. It may light up continuously or flash. In addition, there may be a warning tone. The 7 seat belt warning lamp goes out and the warning tone ceases when the driver and the front passenger have fastened their seat belt. For certain countries only: regardless of whether the driver or the front passenger have fastened their seat belts, the 7 seat belt warning lamp lights up for six seconds after the engine is started. It then goes out if the driver and the front passenger have fastened their seat belts. i The status indicator for the rear-compart- i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belt" (Y page 273).

Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners. The belt tensioners tighten the seat belts in an accident, pulling them close against the body. Belt tensioners do not correct incorrect seat positions or incorrectly fastened seat belts. Belt tensioners do not pull vehicle occupants back towards the backrest. If the seat belt is also fitted with a belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced. The belt force limiters on the front seats are synchronised with the front airbags. They take on a part of the deceleration force, resulting in the force exerted on the occupant being distributed over a greater area. The belt tensioners can only be activated when: Rthe ignition is switched on. restraint systems are operational; see "SRS warning lamp" (Y page 45). Rthe belt tongue is engaged in the buckle on each of the three-point seat belts in the front. The belt tensioners on the seats in the rear compartment are triggered independently of the lock status of the seat belts. The belt tensioners are triggered depending on the type and severity of an accident: Rthe Rif, in the event of a head-on or rear-end col- lision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact Rif, in the event of a side impact, on the side opposite the impact the vehicle deceler- ates or accelerates rapidly in a lateral direction When the belt tensioners are triggered, you will hear a bang and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard. The 6 SRS warning lamp lights up. G WARNING If the seat belt tensioners have been triggered, they provide no additional protection in the event of another accident. Therefore, have belt tensioners which have been triggered replaced at a qualified specialist workshop. Comply with safety regulations when disposing of belt tensioners. Any Mercedes-Benz Service Centre can provide details of these regulations. ! If the front-passenger seat is not occu- pied, do not engage the seat belt tongue in the buckle on the front-passenger seat. Otherwise, the belt tensioner could be triggered in the event of an accident. Children in the vehicle Child restraint systems Important safety notes G WARNING To reduce the risk of serious or even fatal injury to the child in the event of a sudden change in direction, braking or an accident: Rchildren less than 1.50 m tall and under twelve years of age must always be secured in special child restraint systems on a suitable vehicle seat. This is necessary because the seat belts are not designed for children. Rdo not secure children less than 1.50 m tall or under twelve years of age on the frontpassenger seat. Exception: the vehicle is equipped with automatic child seat recognition on the front-passenger seat and the child is secured in a child restraint system with transponders for automatic child seat recognition. Rif you secure a forward-facing child restraint system to the front-passenger seat, you must move the front-passenger seat as far back as possible. Rchildren must never travel sitting on the lap of another occupant. Due to the forces which occur in the event of a sudden change of direction, heavy braking or an accident, it would not be possible to restrain the child. The child could be thrown against parts of the vehicle interior and be seriously or even fatally injured. G WARNING The child restraint system cannot perform its protective function if it is not correctly fitted to a suitable vehicle seat. The child cannot be restrained in the event of an accident, heavy braking or sudden changes of direction. The child could be seriously or even fatally injured. For this reason, when fitting a child restraint system, observe the manufacturer's installation instructions and the correct use of the child restraint system. Child restraint systems should be fitted to the rear seats. Children are generally better protected there. The entire base of the child restraint system must always rest on the seat cushion. Therefore, never place objects, e.g. a cushion, under the child restraint system. Only use child restraint systems with the original cover designed for them. Only replace damaged covers with genuine Mercedes-Benz covers. We recommend the use of child restraint systems which have been approved for Mercedes-Benz vehicles.

Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road and weather conditions, as well as the traffic conditions and maintain a safe distance from the vehicle in front. Drive carefully. i Please note that the driving safety sys- tems described only work as effectively as possible when there is adequate contact between the tyres and the road surface. Pay particular attention to the information Approval number (E1 ...) – Order number – Automatic child seat recognition regarding tyres, recommended minimum tyre tread depths etc. in the "Wheels and tyres" section (Y page 336). In wintry driving conditions, always use winter tyres (M+S tyres) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible. ABS (Anti-lock Braking System) Important safety notes i Observe the "Important safety notes" section (Y page 65). 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. ABS works from a speed of about 8 km/h upwards, regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. G WARNING If ABS is faulty, the wheels could lock when braking. This limits the steerability of the vehicle when braking and the braking distance may increase. If ABS is deactivated due to a malfunction, then BAS and ESP are also deactivated. There is an increased risk of your vehicle skidding in certain situations. Z 65 Safety Driving safety systems 66 Driving safety systems Safety You should always adapt your driving style to suit the prevailing road and weather conditions. Braking If ABS intervenes when braking, you will feel a pulsing in the brake pedal. X 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. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving. G WARNING Do not depress the brake pedal several times in quick succession (pumping). Pumping the brake pedal reduces the braking effect. You might otherwise not be able to stop the vehicle in time and could cause an accident. Depress the brake pedal firmly and smoothly. BAS (Brake Assist) i Observe the "Important safety notes" section (Y page 65). BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. X Keep the brake pedal firmly depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. G WARNING If BAS has malfunctioned, the braking system remains available with full brake boosting effect. However, braking force is not automatically increased in emergency braking sit- uations and the stopping distance may increase. BAS PLUS (Brake Assist System PLUS) BAS PLUS is only available on vehicles with DISTRONIC PLUS. i Observe the "Important safety notes" section (Y page 65). BAS PLUS provides braking assistance in hazardous situations at speeds of over 30 km/h and uses radar sensor technology to assess the traffic situation. With the help of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. At speeds up to approximately 70 km/h, BAS PLUS may also detect stationary obstacles, for example, stopped or parked vehicles. Should you approach an obstacle and BAS PLUS has detected a risk of collision, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. Should you apply the brakes forcefully, BAS PLUS can automatically increase the braking force to a level suitable for the traffic conditions. If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal. is no longer any danger of a rear-end collision. Rno obstacle is detected in front of your vehicle. BAS PLUS is then deactivated. Rthere Vehicles with COMAND and navigation system: the radar sensor system is switched off automatically in the vicinity of radio telescope facilities (Y page 363). Vehicles without COMAND and a navigation system and vehicles for Australia: the radar sensor system and on-board computer must be switched off in the vicinity of radio telescope facilities (Y page 226). For BAS PLUS to assist you when driving, the radar sensor system must be switched on and operational; see "Radar sensor system" in the index. G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. BAS PLUS cannot intervene in these cases. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else covering the sensors Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of strong radar reflections, for example in multi-storey car parks Ra narrow vehicle travelling in front, e.g. a motorbike Ra vehicle travelling in front on a different line G WARNING BAS PLUS does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering As a result, BAS PLUS may not intervene in critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at slow speeds where there is no visible damage to the front of the vehicle. If BAS PLUS 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 lamps i Adaptive brake lamps are only available in certain countries. 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 switch button (Y page 111). ESP® (Electronic Stability Program) Important safety notes i See the "Important safety notes" section (Y page 65). 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. If necessary, 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. Z 67 Safety Driving safety systems 68 Driving safety systems If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. Safety G WARNING If the ÷ warning lamp in the instrument cluster flashes, proceed as follows: not deactivate ESP® under any circumstances.

ESP® trailer stabilisation ESP® trailer stabilisation is not available in AMG vehicles. If your vehicle with trailer (vehicle/trailer combination) begins to lurch, you can only stabilise the vehicle/trailer combination by depressing the brake firmly. In this situation, ESP® assists you and can detect if the vehicle/trailer combination begins to lurch. ESP® slows the vehicle down by braking and limiting the engine output until the vehicle/trailer combination has stabilised. Trailer stabilisation is active above speeds of about 65 km/h. G WARNING X To deactivate: press button : until the å ESP® OFF warning lamp lights up in the instrument cluster. The ÷OFF message appears in the multifunction display. If road and weather conditions are poor, trailer stabilisation will not be able to prevent the trailer from swerving and will thus be unable to reduce the risk of an accident. Trailers with a high centre of gravity can tip over before ESP® can detect this. Trailer stabilisation does not work if ESP® is deactivated or disabled because of a malfunction. EBD (electronic brake force distribution) i Observe the "Important safety notes" section (Y page 65). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. G WARNING If EBD has malfunctioned, the braking system remains available with full brake boosting effect. However, the rear wheels can still lock, e.g. under full braking. This could cause you to lose control of your vehicle and cause an accident. You should therefore adapt your driving style to the different handling characteristics. X Observe the notes on warning and indicator lamps (Y page 275) as well as display messages (Y page 235) (4-button multifunction steering wheel) and (Y page 240) (12button multifunction steering wheel). ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 177) and hill start assist (Y page 140). For further information, see Driving tips (Y page 159). PRE-SAFE® Brake PRE-SAFE® Brake is only available in vehicles with DISTRONIC PLUS. i Observe the "Important safety notes" section (Y page 65). PRE-SAFE® Brake can help you to minimise the risk of a frontal collision with a vehicle ahead or reduce the effects of such a collision. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. This function will issue a warning at speeds of around 30 km/h or more if: Rfor a period of several seconds, the distance to the vehicle in front is too short for the speed at which you are travelling. The · distance warning lamp then lights up in the instrument cluster. Ryou are rapidly approaching the 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. If the driver and passengers have fastened their seat belts, PRE-SAFE® Brake can also can also perform the following at speeds of above approximately 30 km/h: Rbrake the vehicle automatically from a speed of up to approximately 200 km/h Rtrigger preventative passenger protection measures (PRE-SAFE®) (Y page 50) Due to the nature of the system, particularly complicated driving conditions may cause unnecessary warnings or the unnecessary intervention of PRE-SAFE® Brake. To end this, you can either depress the accelerator pedal further, activate kickdown or release the brake pedal. The braking action of PRE-SAFE® Brake is ended automatically if: Ryou drive slower than approximately 15 km/h. Ryou manoeuvre to avoid the obstacle. Z 71 Safety Driving safety systems 72 Driving safety systems Safety Rthere is no longer any danger of a rear-end collision. Rthere is no longer an obstacle detected in front of your vehicle. With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. At speeds up to approximately 70 km/h, PRE-SAFE® Brake may also detect stationary obstacles, for example stopped or parked vehicles. If you approach an obstacle and PRE-SAFE® Brake detects a risk of a collision, the system will initially alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventative passenger protection measures (PRE-SAFE®) are activated (Y page 50). If the risk of collision remains and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided. G WARNING Even if PRE-SAFE® Brake slows the vehicle before an imminent rear-end collision, the system cannot avert a collision without the intervention of the driver. There is a risk of an accident. Brake according to the situation or take evasive action. Delayed intervention by the driver can lead to an accident. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then brake the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation. In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else covering the sensors Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of strong radar reflections, for example in multi-storey car parks Ra narrow vehicle travelling in front, e.g. a motorbike Ra vehicle travelling in front on a different line G WARNING PRE-SAFE® Brake does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Rto As a result, PRE-SAFE® Brake may not give warnings or intervene in critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. X To activate/deactivate: activate or deactivate PRE-SAFE® Brake in the on-board computer (Y page 221). The Ä symbol appears in the multifunction display as long as the HOLD function is not activated (Y page 177).

Overview of climate control systems Important safety notes G WARNING Observe the settings recommended on the following pages. Otherwise, the windows could mist up. This may obstruct your view of the traffic situation and, as a result, you may cause an accident. THERMATIC automatic climate control controls the temperature and the humidity in the vehicle interior and filters undesirable substances from the air. THERMATIC automatic climate control is only operational when the engine is running. Optimum operation is only achieved when you drive with the side windows and panorama sliding sunroof closed. i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 88). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly. i The integrated filter can filter out most particles of dust and completely filters out pollen. 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 it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. i It is possible that the residual heat func- tion may be activated automatically an hour after the key is removed. The vehicle is then ventilated for 30 minutes to dry the airconditioning system.

Running-in notes Important safety notes G WARNING New brake pads/linings only have optimal braking performance after several hundred kilometres. Until then, compensate for this by applying greater force to the brake pedal. This also applies when brake pads/linings or brake discs have been changed. The first 1,500 km The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. RTherefore, drive at varying speeds and engine speeds for the first 1,500 km. RAvoid heavy loads on the engine during this period, e.g. driving at full throttle. RChange gear in good time, at the latest when the rev counter needle is 2/3 of the way to the red area in the rev counter display. RDo not manually shift to a lower gear to brake the vehicle. Vehicles with automatic transmission: RIf possible, do not depress the accelerator pedal past the point of resistance (kickdown). ROnly select shift ranges 3, 2 or 1 when driving slowly, e.g. in mountainous terrain. After 1,500 km, you may gradually bring the vehicle up to full road and engine speeds. Additional running-in notes for AMG vehicles: Rdo not drive at speeds above 140 km/h for the first 1,500 km. allow the engine to reach a maximum engine speed of 4,500 rpm briefly. Ronly i You should also observe these notes on running in if the engine or parts of the drive train on your vehicle have been replaced. AMG vehicles with rear axle locking differential Your vehicle is fitted with a self-locking differential on the rear axle. Change the oil after a running-in period of 3,000 km to improve protection of the rear axle differential. This oil change extends the service life of the differential. Have the oil change carried out at a qualified specialist workshop. MercedesBenz recommends that you use a MercedesBenz Service Centre for this purpose. Driving Important safety notes G WARNING Do not place any objects in the driver's footwell. If you use a floormat or carpet in the driver's footwell, make sure that it is correctly secured and that there is sufficient clearance for the pedals. Do not place several floormats on top of one another. Loose objects or the floormats could otherwise get caught between the pedals if you Driving Key positions Key Driving and parking accelerate or brake suddenly. You will then not be able to brake, declutch or accelerate as intended. This could lead to accidents and injury. G WARNING Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid. This could cause you to lose control of your vehicle and cause an accident. ! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only set the automatic transmission to the respective drive positions when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. Otherwise, you could damage the drive train. !

The fuel lines and/or the diesel injection system could otherwise be blocked by particles from the fuel can. but only as a temporary measure, you may also use regular unleaded petrol, 91 RON/82.5 MON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle. In some countries, the fuel grade available may not be adequate and could cause deposits to build up. In such cases, and in consultation with a Mercedes-Benz Service Centre, the petrol may be mixed with the additive recommended by Mercedes-Benz (part number A000989254510). You must observe the notes and mixing ratios specified on the container. Fuel grade For further information on "Fuel", see (Y page 354). ! Only refuel using unleaded premium- AMG vehicles and 12-cylinder engines grade petrol with at least 95 RON/85 MON, which conforms to European standard EN 228 or an equivalent specification. ! Do not use the following: RE85 (petrol with 85% ethanol) (100% ethanol) RM15 (petrol with 15% methanol) RM85 (petrol with 85% methanol) RM100 (100% methanol) RDiesel Do not mix these fuels with petrol, and do not use any additives. Otherwise, this can lead to damage to the engine. This does not include additives for the removal and prevention of residue build-up. Only additives recommended by Mercedes-Benz may be added to petrol. More information about recommended additives can be obtained from any Mercedes-Benz Service Centre. RE100 ! Only refuel using super-grade unleaded petrol with at least 98 RON/88 MON, which conforms to European standard EN 228 or equivalent. You can otherwise impair engine output or damage the engine. i If the recommended fuel is not available and only as a temporary measure, you may also use premium-grade unleaded petrol, 95 RON/85 MON. This may reduce engine performance and increase fuel consumption. Avoid driving at full throttle. ! In emergencies, and only if the recom- mended fuel is not available, you may also use standard unleaded petrol, 91 RON/ 82.5 MON. However, using this fuel results in considerably higher petrol consumption and significantly reduced engine performance. Avoid driving at full throttle. Z Driving and parking ! Do not use petrol to refuel vehicles with a 153 Driving and parking 154 Refuelling If no fuel other than regular petrol with 91 RON/82.5 MON or a lower grade is permanently available, you should have the vehicle adapted to run on this fuel in a qualified specialist workshop. MercedesBenz recommends that you use a Mercedes-Benz Service Centre for this purpose. C 350 BlueEFFICIENCY ! Only refuel using unleaded, sulphur-free premium-grade petrol with at least 95 RON/85 MON, which conforms to European standard EN 228 or an equivalent specification. You can 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. Diesel (EN 590) Fuel grade ! When refuelling, only use diesel fuel that conforms to the European standard EN 590 or is of equivalent quality. You can otherwise impair engine output or damage the engine. ! Vehicles with diesel particle filters: in countries outside the EU, only use low sulphur Euro diesel with a sulphur content of under 50 ppm. Otherwise, the emission control system could be damaged. ! Vehicles without a diesel particle fil- ter: in countries where only diesel fuels with a higher sulphur content are available, the vehicle's oil change intervals are shorter. More information about intervals for changing the oil can be obtained from any Mercedes-Benz Service Centre. ! Only use fuel that complies with the EN 590 European standard. Fuel that does not comply with EN 590 can lead to increased wear, engine damage and damage to the exhaust system. Do not use the following: Rmarine diesel oil Rbio-diesel Rvegetable oil Rpetrol Rparaffin Rkerosene Do not mix these fuels with diesel fuels and do not use any special additives. Otherwise, this can lead to damage to the engine. This excludes flow improver; see "Low outside temperatures". Rheating ! Use a filter when adding fuel from a fuel can. Otherwise, the fuel lines and/or the diesel injection system could be blocked by particles from the fuel can. For further information on "Fuel", see (Y page 354). Low outside temperatures Diesel fuel with improved cold flow qualities is available during the winter months. In Europe, various climate-dependent low-temperature classes are defined in EN 590. Refuelling with diesel fuel which complies with the climatic specifications of standard EN 590 can help to prevent operating problems. At exceptionally low temperatures, it is possible that the flow properties of the fuel may be inadequate. This also applies to fuel that has not been adapted to suit the climatic conditions, e.g. diesel fuel from warmer regions. i Further information about country-spe- cific fuel properties can be obtained from oil companies, e.g. at filling stations. Refuelling 155 Flow improvers can be added to improve the cold resistance of diesel fuel. The effectiveness of a flow improver is not guaranteed with every fuel. Correct dosage and thorough mixing are decisive factors in ensuring improvement in lowtemperature resistance. Under certain circumstances, an excessive dosage may actually decrease low-temperature resistance and should therefore be avoided. Follow the manufacturer's dosing instructions. Mix the additive with the diesel in good time, before the flow properties of the diesel become inadequate. Malfunctions can otherwise only be rectified by heating the entire fuel system, e.g. by parking the vehicle in a heated garage. Observe the information provided by the manufacturer when using a flow improver. Only use flow improvers that have been tested and approved by Mercedes-Benz. You can obtain further information from any Mercedes-Benz Service Centre.

If you leave the vehicle parked up for longer than six weeks, the vehicle may suffer damage as a result of lack of use. X Visit a qualified specialist workshop and seek advice. Never switch the engine off while the vehicle is in motion. There is no power assistance for the steering and the service brake when the engine is not running. You will require considerably more effort to steer and brake, and you could therefore lose control of the vehicle and cause an accident. Engine oil ! Vehicles with a diesel particle filter: If the vehicle is mostly driven for short distances, it is possible that malfunctions may occur during the automatic cleaning of the diesel particle filter. This can lead to engine damage. Therefore, if you frequently drive short distances, make sure to drive on motorways or country roads for 20 minutes at least every 500 km. Brakes Important safety notes G WARNING Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid. G WARNING Make sure that other road users are not endangered by your braking. Downhill gradients On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must shift to a lower gear in good time or, Z Driving and parking Rolling with the engine switched off 160 Driving tips on vehicles with automatic transmission, select shift range 1, 2 or 3. Driving and parking i This also applies if you have activated cruise control, SPEEDTRONIC or DISTRONIC PLUS. This will use the braking effect of the engine, so less braking will be required to maintain the speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Heavy and light loads G WARNING Never depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by applying constant slight pedal pressure. This causes the brake system to overheat, increases the braking distance and can lead to the brakes failing completely. If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly. If the brakes have been used only moderately, you should occasionally test their effectiveness. To do this, brake more firmly from a higher speed. This improves the grip of the brakes. Wet road surface If driving in heavy rain for a prolonged period of time without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after the vehicle has been washed. You have to depress the brake pedal more firmly. Maintain a greater distance from 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 salt treated roads G WARNING The layer of salt on the brake discs and the brake pads/linings may cause a delay in the braking effect, resulting in a significantly longer braking distance, which could lead to an accident. To avoid this danger, you should: Roccasionally brake carefully, without putting other road users at risk, when you are driving on salted roads. This helps to remove any salt that may have started to build up on the brake discs and the brake pads/linings. Rmaintain a greater distance to the vehicle ahead and drive with particular care. Rcarefully apply the brakes at the end of a trip and immediately after commencing a new trip, so that salt residues are removed from the brake discs. New brake pads/linings G WARNING New brake pads/linings only reach their optimum braking effect after several hundred kilometres of driving. Before this optimum braking effect is reached, you should compensate for the reduced braking effect by applying greater pressure when braking. This also applies after the brake discs or the brake pads/linings have been replaced. 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 tips The high-performance brake system is designed for heavy loads. This may lead to noise when braking. This will depend on: Rspeed Rbraking force Renvironmental conditions, such as temperature and humidity The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions. For this reason, it is impossible to state a mileage that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your Mercedes-Benz Service Centre. Tyre traction G WARNING Whereas the vehicle can be fully controlled at a certain speed on dry roads, you must reduce your speed on wet or icy roads to achieve the same road safety. You could otherwise cause an accident. Pay particular attention to the road conditions at temperatures around freezing point. If ice has formed on the road surface (e.g. from fog), a thin film of water rapidly forms on the ice when you brake, considerably reducing tyre traction. Drive with particular care in such weather conditions. 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 drive at low speeds tyres have adequate tread depth For this reason, do not drive in tyre ruts, and brake carefully. Rthe Driving on flooded roads If you have to drive on stretches of road on which water has collected, please bear in mind that: Rthe maximum permitted still water depth is 25 cm. should drive no faster than at walking pace. Ryou ! 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. Winter driving General notes G WARNING If the vehicle becomes trapped in snow, ensure that snow is kept away from the exhaust pipe and from around the vehicle as long as the engine is running. Otherwise, poisonous carbon monoxide (CO) may enter the vehicle, resulting in loss of consciousness and even death. To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. Z Driving and parking High-performance brake system for AMG vehicles 161 Driving systems Driving and parking 162 At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at a Mercedes-Benz Service Centre. Observe the notes in the "Winter operation" section (Y page 337). Driving with summer tyres Observe the notes in the "Winter operation" section (Y page 337). Slippery road surfaces G WARNING Do not shift down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid. You should drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking manoeuvres. If the vehicle threatens to skid or cannot be stopped when moving at low speed: Vehicles with manual transmission: engage 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 i For more information on driving with snow chains, see (Y page 338). Driving systems Cruise control Important safety notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must shift to a lower gear in good time or select shift range 1, 2 or 3 on vehicles with automatic transmission. By doing so, you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. G WARNING Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid. Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 30 km/h. G WARNING Cruise control cannot take account of road and traffic conditions. Always pay attention to traffic conditions even when cruise control is activated. Cruise control is only an aid designed to assist driving. You are responsible for the vehicle's speed and for braking in good time. G WARNING Do not use cruise control Rin traffic conditions that do not allow you to drive at a constant speed (e.g. heavy traffic or winding roads). You may otherwise cause an accident.

DISTRONIC PLUS Important safety notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. It brakes automatically in order to avoid exceeding the set speed. Driving systems G WARNING Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid. G WARNING DISTRONIC PLUS is only an aid designed to assist driving. The driver remains fully responsible for the vehicle's distance from other vehicles, the vehicle's speed and for braking in good time. DISTRONIC PLUS does not react in particular to: Rpedestrians Rstationary obstacles on the road, e.g. stop- ped or parked vehicles and crossing traffic DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. Therefore, always pay attention to traffic conditions even when DISTRONIC PLUS is activated. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Roncoming G WARNING DISTRONIC PLUS cannot take account of road and traffic conditions. If DISTRONIC does not recognise or no longer recognises the vehicle in front, do not activate DISTRONIC or, if it is already active, deactivate it. This is especially the case: Rbefore corners filter lanes Rwhen changing to a lane with faster moving traffic Rin complex driving situations or where lanes are diverted, e.g. at roadworks on a motorway DISTRONIC PLUS otherwise maintains the current speed set by you or accelerates up to the set speed. DISTRONIC PLUS cannot take account of weather conditions. Deactivate, or do not activate, DISTRONIC PLUS: Ron Rif the roads are slippery, snow-covered or icy. The wheels could lose their grip when braking or accelerating. The vehicle could start to skid. Rif the sensors are dirty or there is poor visibility, e.g. due to snow, rain or fog. Distance control may be impaired. Always pay attention to traffic conditions even when DISTRONIC PLUS is activated. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. ! You must deactivate the radar sensor system in certain countries and near radio telescope facilities. You will find further information under "Radar sensor system" in the index. The radar sensor system is automatically deactivated near radio telescope facilities (Y page 363). If you want DISTRONIC PLUS to assist you, the radar sensor system must be activated (Y page 226) and operational. Z Driving and parking On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must select shift range 1, 2 or 3 in good time. By doing so, you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If a slower-moving vehicle is detected in front, DISTRONIC PLUS causes your vehicle to brake and maintain a preset distance to the vehicle in front. 165 Driving and parking 166 Driving systems If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 30 km/h and 200 km/h. If a vehicle is driving in front of you, DISTRONIC operates in the speed range between 0 km/h and 200 km/h. Do not use DISTRONIC PLUS while driving on roads with steep gradients. G WARNING DISTRONIC PLUS brakes your vehicle up to a maximum of 4 m/s2 depending on its speed. This corresponds to approximately 40% of your vehicle's maximum braking power. You must also apply the brakes yourself if this braking power is not sufficient. If DISTRONIC PLUS detects a risk of collision with a vehicle in front, an intermittent warning tone sounds. In addition, the · distance warning lamp in the instrument cluster lights up. Brake to avoid a collision.

X Keep the cruise control lever pressed up : or down A until the desired speed is set. i You can use the cruise control lever to set the stored speed and the control on the cruise control lever to set the specified minimum distance (Y page 170). Pulling away X If the vehicle in front pulls away: 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. Driving If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If a slower-moving vehicle is detected in front, DISTRONIC PLUS causes your vehicle to brake and maintain a preset distance to the vehicle in front. Z Driving and parking To activate the DISTRONIC PLUS, the following conditions must be fulfilled: 167 168 Driving systems Driving and parking If DISTRONIC PLUS detects a faster-moving vehicle in front, it increases the driving speed, but only up to the desired speed you have stored. G WARNING If you depress the brake, DISTRONIC PLUS is deactivated unless your vehicle is stationary. DISTRONIC PLUS then no longer brakes your vehicle. In such cases, control the distance from vehicles travelling in front with the brake alone. You could otherwise cause an accident and thereby injure yourself and others. The driver remains fully responsible for the vehicle's distance from other vehicles, the speed being driven and for braking in good time. Changing lanes If you wish to change to the passing lane (in countries where traffic drives on the right, the passing lane is the left-hand lane), DISTRONIC PLUS supports you if: are driving faster than 60 km/h. PLUS is maintaining the distance to a vehicle in front. Ryou switch on the appropriate turn signals. 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. Vehicles with COMAND Online i The following function is not operational in all countries. DISTRONIC PLUS uses additional information from your navigation system so that it can react appropriately to certain traffic situations. This is the case if, while following a vehicle, DISTRONIC PLUS is active and you: Rapproach or drive through a roundabout a T junction Rturn off at a motorway exit Even if the vehicle in front leaves the detection range, DISTRONIC PLUS temporarily maintains the current driving speed and does not accelerate. This is based on the current map data in the navigation system. Rapproach Ryou RDISTRONIC G WARNING DISTRONIC PLUS and Active Blind Spot Assist are only an aid designed to assist driving. They do not relieve you of the responsibility of paying attention. The driver remains fully responsible for the vehicle's distance from other vehicles, the vehicle's speed and for braking in good time. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Example: roundabout The current speed is maintained: Rapproximately 10 seconds before the roundabout/T junction and for approximately 1.5 seconds when driving on the roundabout Rapproximately 12 seconds before reaching a motorway exit and approximately 4 seconds after the motorway exit Afterwards, the vehicle accelerates back to the set speed you specified.

Ryou accelerate. Rthere is a malfunction in the system or an interruption in the power supply, e.g. battery failure. Rthe electrical system in the engine compartment, the battery or the fuses are tampered with. Rthe battery is disconnected. If you wish to leave the vehicle or park it, deactivate DISTRONIC PLUS and secure the vehicle against rolling away. If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. Once your vehicle is stationary, it remains stationary and you do not need to depress the brake. i Depending on the specified minimum dis- tance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. You will see a warning message in the multifunction display if DISTRONIC PLUS is activated and: Rthe driver's door is open and the driver's seat belt is unfastened. Rthe engine is switched off, unless it is automatically switched off by the ECO start/ stop function. Rthe bonnet is opened. Select Park (P) the engine off, open the driver's door and take off your seat belt Ropen the bonnet The sounding of the horn alerts you to the fact that the vehicle has been parked while DISTRONIC PLUS is still activated.

Vehicles travelling on a different line DISTRONIC PLUS may not detect vehicles travelling on a different line. The distance to the vehicle in front will be too short. Driving systems Other vehicles changing lane 173 detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Driving and parking Crossing vehicles DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles DISTRONIC PLUS may detect vehicles that are crossing your lane by mistake. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally. SPEEDTRONIC Important safety notes DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the carriageway, because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles SPEEDTRONIC brakes automatically so that you do not exceed the set speed. On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must shift to a lower gear in good time or select shift range 1, 2 or 3 on vehicles with automatic transmission. By doing so, you will make use of the braking effect of the engine, which 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. G WARNING DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the Never depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by applying constant slight pedal pressure. This causes the brake system to overheat, increases the braking distance and can lead to the brakes failing completely. Z 174 Driving systems Driving and parking G WARNING Do not change down for additional engine braking on a slippery road surface. This could cause the drive wheels to lose their grip and the vehicle could skid.

PARKTRONIC Important safety notes G WARNING PARKTRONIC is only an aid and may not detect all obstacles. It is not a substitute for attentive driving. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and manoeuvring. You could otherwise endanger yourself and others. Z Driving and parking Conditions for activation 179 180 Driving systems G WARNING Driving and parking Make sure that no persons or animals are in the manoeuvring range. Otherwise, they could be injured. PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is activated automatically when you: Rswitch on the ignition Rshift to position D, R or N on vehicles with automatic transmission Rrelease the parking brake PARKTRONIC is deactivated at speeds above 18 km/h. It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper. Side view Top view Front sensors Centre approximately 100 cm Corners approximately 60 cm Rear sensors : Sensors in the front bumper, left-hand side (example) Range of the sensors General notes The sensors must be free of dirt, ice and slush; otherwise, they may not function correctly.

Ultrasound is used to measure the road on both sides of the vehicle. A suitable parking space is indicated by the parking symbol. You receive steering instructions when parking. You may also use PARKTRONIC (Y page 179). G WARNING Parking Guidance is merely an aid and may recommend parking spaces that are not suitable for parking. For example, these might be spaces where parking is prohibited, driveways, unsuitable surfaces, etc. Parking Guidance measures the parking space as you drive past it. Any later changes to the parking space are not taken into account. For instance, this may be the case when the vehicle parked in front of or behind the space changes its position or when an obstacle is moved into the parking space. Parking Guidance does not relieve you of the responsibility for paying attention. If you rely solely on Parking Guidance, you could cause an accident and injure yourself and others. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and manoeuvring. G WARNING Objects located above the height range of Parking Guidance 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. In some circumstances, Parking Guidance Z Driving and parking Problem 184 Driving systems Driving and parking might therefore issue steering instructions too soon. This may lead to a collision. For this reason, you should avoid using Parking Guidance in such situations. G WARNING Make sure that no persons or animals are in the manoeuvring range. Otherwise, they could be injured. lead you across or onto the kerb. If necessary, cancel the parking procedure with Parking Guidance. ! 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. Detecting parking spaces When PARKTRONIC is deactivated, Parking Guidance is also unavailable. Use Parking Guidance for parking spaces: Rthat are parallel to the direction of travel are on straight roads, not bends Rthat are on the same level as the road, i.e. not on the pavement, for example. Parking Guidance may not detect flat kerbs Parking tips: ; Parking symbol Ron = Detected parking space on the right Rthat narrow roads, drive past the parking space as close as possible. Rparking spaces that are littered, overgrown or partially occupied by trailer drawbars might be identified incorrectly or not at all. Rsnowfall or heavy rain may lead to a parking space being measured inaccurately. Rpay attention to the PARKTRONIC (Y page 181) warning messages during the parking procedure. Rwhen transporting a load which protrudes from your vehicle, you must not use Parking Guidance. Rnever use Parking Guidance with snow chains or an emergency spare wheel fitted. Rmake sure that the tyre pressures are always correct. This has a direct effect on the steering instructions. Rthe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. In some cases, Parking Guidance may guide you too far or not far enough into a parking space. In some cases, it may also Example: vehicles with automatic transmission : Detected parking space on the left Parking Guidance is automatically activated when you drive 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. 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. Parking Guidance 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. To park on the driver's side, you must leave the driver's side turn signal switched on until you have engaged reverse gear. Driving systems 185 Parking Guidance will only detect parking spaces: Rthat are parallel to the direction of travel are at least 1.5 m wide Rthat are at least 1.3 m longer than your vehicle A parking space is displayed while you are driving past it, and until you are approximately 15 m away from it.

ATTENTION ASSIST Important safety notes ATTENTION ASSIST helps you during long, monotonous journeys such as on motorways and trunk roads. It is active in the 80 km/h to 180 km/h range. If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break. The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the road condition is poor, e.g. if the surface is uneven or if there are potholes Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration Rif you are predominantly driving slower than 80 km/h or faster than 180 km/h Rif you are currently using COMAND Online or making a telephone call with it Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed Warning and display messages in the multifunction display G WARNING ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentration too late or not at all. It is not a substitute for a well rested and attentive driver. Fatigue may cause you to recognise hazardous situations too late, misjudge a situation or react slower. For this reason, make sure you feel rested before you begin driving and during your journey. Always take breaks in good time and regularly, especially during long journeys. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. ATTENTION ASSIST assesses your level of fatigue or lapses in concentration by taking the following criteria into account: Ryour personal driving style, e.g. steering characteristics Rdriving conditions, e.g. time, driving time Example: vehicles with automatic transmission X Activate ATTENTION ASSIST using the onboard computer (Y page 222). Symbol : appears in the multifunction display. If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun.

Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 190) and Lane Keeping Assist (Y page 192). Blind Spot Assist Important safety notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. Blind Spot Assist provides assistance at speeds higher than 30 km/h. A warning display in the exterior mirrors draws your attention to detected vehicles in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive a visual and acoustic collision warning. The Blind Spot Assist monitoring system uses sensors in the rear bumper. G WARNING Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehicles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traffic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow, rain or mist, for example. In this case, vehicles are detected late or not at all. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. The radar sensor system is automatically deactivated near radio telescope facilities (Y page 363). For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 226) and operational. Driving systems G WARNING Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. There is no display and no warning. If the lanes are very wide, it may not be possible to monitor the complete width of the neighbouring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation in different lanes. This may be the case if vehicles are driving at the edge of their lane that is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. If the lanes are narrow, the system may be unable to distinguish the neighbouring lane from the one beyond it. For this reason, vehicles in the farther lane may be indicated, especially if the vehicles are driving in a staggered formation in different lanes. In particular, this may be the case if the vehicles are driving at the edge of their lane nearest your vehicle. 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. The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush around the sensors. For example, the radar sensors must not be covered 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, e.g. a Mercedes-Benz Service Centre. Blind Spot Assist may otherwise not work properly. Indicator and warning display : Yellow indicator lamp/red warning lamp If Blind Spot Assist is switched on, indicator lamp : in the exterior mirrors lights up yellow up to a speed of 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and 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 in red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or Z Driving and parking Monitoring range of the sensors Blind Spot Assist monitors the area up to three metres behind your vehicle and directly next to your vehicle, as shown in the diagram. 191 Driving and parking 192 Driving systems 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. G WARNING Blind Spot Assist is not active at speeds below 30 km/h, and the indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the 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. Switching on Blind Spot Assist X On vehicles without a navigation system, make sure that the Becker® MAP PILOT is connected; see the separate operating instructions for Audio 20. X Make sure that the radar sensor system (Y page 226) and Blind Spot Assist (Y page 222) are activated in the on-board computer. X Turn the key to position 2 in the ignition lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5 seconds and then turn yellow. Trailer towing If you attach a trailer, make sure you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. In this event, Blind Spot Assist is deactivated. The indicator lamp in the exterior mirrors lights up yellow, and the Blind Spot Assist currently unavail‐ able See Owner's Manual message appears in the multifunction display. i You can deactivate the indicator lamps in the exterior mirrors. To do so, switch off Blind Spot Assist if: Rthe key is in position 2 in the ignition lock. Rthe engine is not running. Rthe electrical connection to the trailer has been established. Lane Keeping Assist Important safety notes Lane Keeping Assist monitors the area in front of your vehicle by means of a camera at the top of the windscreen. Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally. : Lane Keeping Assist camera If you have chosen the Display unit Speed-/odometer:(Y page 223) function in the on-board computer and select kmkm as the unit of measurement, Active Lane Keeping Assist is active from speeds of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. G WARNING Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray. Rthere is glare, e.g. from oncoming traffic, the sun, or reflection from other vehicles. Rthe windscreen is dirty, misted up or covered, for instance by a sticker, in the vicinity of the camera Rseveral or no lane markings for a single lane are present. 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 on the road are unclear, e.g. near roadworks. Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge. Rthe road is narrow and winding. Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognises certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a bend. Rthe road has very wide lanes, e.g. a motorway. Rthe system recognises solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. cut the corner on a bend. No warning vibration occurs if: Ryou Ryou clearly and actively steer, brake, or accelerate. Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, such as ABS, BAS or ESP®. Ryou have switched on the turn signals. In this event, the warnings are suppressed for a certain period of time. Activating Lane Keeping Assist Example: vehicles with automatic transmission X Activate Lane Keeping Assist using the onboard computer (Y page 222). Symbol : appears in the multifunction display. If you drive at speeds above 60 km/h and lane markings are detected, symbol : is displayed in green. Lane Keeping Assist is ready for use.

Active Blind Spot Assist Important safety notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle that are behind the driver. A warning display in the exterior mirrors draws your attention to detected vehicles in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive a visual and acoustic collision warning. If a risk of lateral collision is detected, corrective braking may help you avoid a collision. To support the course-correcting brake application, Active Blind Spot Assist also uses the forward-facing radar sensor system. Active Blind Spot Assist provides assistance at speeds higher than about 30 km/h. style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. The radar sensor system is automatically deactivated near radio telescope facilities (Y page 363). For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 226) and operational. Monitoring range Active Blind Spot Assist monitors the area up to three metres behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper. G WARNING Active Blind Spot Assist is only an aid and may detect vehicles/obstacles incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to snow, rain, fog or spray. Rthe rear and/or front sensors are dirty. Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or only detect them too late. It cannot detect vehicles which are overtaken at a small distance and then enter the blind spot area. Active Blind Spot Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving G WARNING Active Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course. If the lanes are very wide, it may not be possible to monitor the complete width of the neighbouring lane. For this reason, vehicles in Driving systems 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. Two Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers respectively. An additional radar sensor is located behind the cover in the radiator grille. Make sure that the bumpers are free of dirt, ice or slush around the sensors. The rear 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, e.g. a Mercedes-Benz Service Centre. Active Blind Spot Assist may otherwise fail to work correctly. Indicator and warning display : Yellow indicator lamp/red warning lamp When Active Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up in yellow at speeds of up to 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and Active Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 30 km/h, warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 12 km/h. The yellow indicator lamp goes out if reverse gear is engaged. Active Blind Spot Assist is then no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G WARNING Active Blind Spot Assist is not active at speeds below 30 km/h. The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Z Driving and parking the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at the edge of their lane that is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. 195 Driving and parking 196 Driving systems Visual and acoustic collision warning If you switch on the appropriate turn signals to change lanes, and a vehicle is detected in the side monitoring range of Active Blind Spot Assist, you will receive a visual and acoustic collision warning. You will then hear a double warning tone, and red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Course-correcting brake application If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is designed to help you avoid a collision. The course-correcting brake application is available in the range between 30 km/h and 200 km/h. If a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and the following is shown in the multifunction display, for example: Example: vehicles with automatic transmission G WARNING Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. Automatic braking by the system may not always be sufficient to avoid a collision. In such cases, you need to steer, brake or accelerate yourself. In very rare cases, the system may detect a risk of collision where there is none and brake in error near crash barriers or similar road boundaries. Active Blind Spot Assist cannot detect all traffic situations and road users. Ensure at all times that there is sufficient lat- eral distance between you and other road users or obstacles. You can, for example, countersteer gently or depress the accelerator pedal at any time to cancel inappropriate braking action. You are responsible for the vehicle's speed, correct steering and for braking in good time. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Either a very slight course-correcting brake application, or none at all, may occur if: Rthere are vehicles or obstacles, e.g. crash barriers, on both sides of your vehicle. Ra vehicle approaches too closely on the side. Ryou have adopted a sporty driving style with high cornering speeds. Ryou brake or accelerate decisively. Ra driving safety system intervenes, such as ESP® or PRE-SAFE® Brake. RESP® is deactivated. Ra loss of tyre pressure or a defective tyre is detected. Activating Active Blind Spot Assist X On vehicles without a navigation system, make sure that the Becker® MAP PILOT is connected; see the separate operating instructions for Audio 20. X Make sure that the radar sensor system (Y page 226) and Active Blind Spot Assist (Y page 222) are activated in the on-board computer. X Turn the key to position 2 in the ignition lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5 seconds and then turn yellow. Driving systems Active Lane Keeping Assist Important safety notes Active Lane Keeping Assist monitors the area in front of your vehicle by means of a camera at the top of the windscreen. Active Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally. If you do not react to the warning, a lane-correcting application of the brakes can bring the vehicle back into the original lane. : Active Lane Keeping Assist camera If you have selected the Display unit Speed-/odometer:(Y page 223) function in the on-board computer and select kmkm as the unit of measurement, Active Lane Keeping Assist is active from speeds of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all. The system may be impaired or may not function if: Rseveral or no lane markings for a single lane are present. 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. Rthe windscreen is dirty, misted up or covered, for instance by a sticker, in the vicinity of the camera. 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 on the road are unclear, e.g. near roadworks. Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge. Rthe road is narrow and winding. Active Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. Rthere Warning vibration in the steering wheel A warning may be given if a front wheel passes over a lane marking. You will be warned by way of intermittent vibrations in the steering wheel for up to 1.5 seconds. In order that you are warned only when necessary and in good time if you cross the lane Z Driving and parking Trailer towing If you attach a trailer, make sure you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. Active Blind Spot Assist is then deactivated. The indicator lamp in the exterior mirrors lights up yellow, and the Active Blind Spot Assist currently unavailable See Owner's Manual message appears in the multifunction display. 197 198 Driving systems marking, the system recognises certain conditions and warns you accordingly. The warning vibration occurs earlier if: Driving and parking Ryou approach the outer lane marking on a bend. Rthe road has very wide lanes, e.g. a motorway. Rthe system recognises solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. Ryou cut the corner on a bend. No warning vibration occurs if: Ryou clearly and actively steer, brake, or accelerate. Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, such as ABS, BAS or ESP®. Ryou have switched on the turn signals. In this event, the warnings are suppressed for a certain period of time. Lane-correcting brake application If you leave your lane under certain circumstances, the vehicle will brake briefly on one side. This is designed to help you bring the vehicle back into the original lane. This function is available in the range between 60 km/h and 200 km/h. A lane-correcting brake application can only be made after driving over a solid, recognisable lane marking. Before this, a warning must be emitted by means of intermittent vibration in the steering wheel. In addition, a lane with lane markings on both sides must be recognised. The brake application also slightly reduces driving speed. If a lane-correcting brake application occurs, the following message appears in the multifunction display: Example: vehicles with automatic transmission i A further lane-correcting brake applica- tion can only occur after your vehicle has returned to the original lane. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid designed to assist driving. It is not a substitute for attentive driving. Corrective braking may not always be sufficient to return your vehicle to its original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist cannot detect the current traffic situation or other road users. Ensure at all times that there is sufficient lateral distance between you and other road users or obstacles. In rare cases, broken lines or certain structures on the road surface may be detected by the system as solid lane markings. You can, for example, countersteer gently at any time to cancel inappropriate braking action, e.g. if you intentionally drive across a solid lane marking. Active Lane Keeping Assist cannot take weather conditions into account. You are responsible for the vehicle's speed, correct steering and for braking in good time. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. No lane-correcting brake application occurs if: Ryou clearly and actively steer, brake, or accelerate. Ryou cut the corner on a sharp bend. Ryou have switched on the turn signals.

Symbol : appears in the multifunction display. If you drive at speeds above 60 km/h and lane markings are detected, symbol : is displayed in green. Active Lane Keeping Assist is ready for use. Trailer towing If you attach a trailer, make sure you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. Trailer towing Notes on towing a trailer Important safety notes G WARNING When reversing the vehicle towards the trailer, make sure there is nobody between the trailer and the vehicle. Couple and uncouple the trailer carefully. If you do not couple the trailer to the towing vehicle correctly, the trailer could become detached. Make sure that the following values are not exceeded: Rthe permissible trailer drawbar noseweight Rthe permissible trailer load Rthe permissible rear axle load of the towing vehicle maximum permissible gross vehicle weight of both the towing vehicle and the trailer You will find the applicable permissible values, which must not be exceeded, in the vehicle documents. You will find the values approved by the manufacturer on the vehicle identification plates and those for the towing vehicle in the "Technical data" section. Rthe Z 199 Driving and parking Trailer towing 200 Trailer towing Driving and parking G WARNING If the Check trailer hitch locking mechanism message appears in the multifunction display while the vehicle is in motion, pull over immediately and check whether the ball coupling is correctly engaged. G WARNING Always observe the maximum speed permitted in Germany for vehicle/trailer combinations, even in countries where higher speeds are permitted. This lowers the risk of an accident. G WARNING Never depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by applying constant slight pedal pressure. This causes the brake system to overheat, increases the braking distance and can lead to the brakes failing completely. G WARNING On no account should you attempt to draw the vehicle/trailer combination out by increasing speed. General information i When towing a trailer, set the tyre pres- sure on the rear axle of the towing vehicle for a maximum load; see the tyre pressure table in the fuel filler flap (Y page 339). You will find installation dimensions and loads in the "Technical data" section (Y page 361). The maximum permissible trailer drawbar noseweight on the ball coupling is 75 kg. However, the actual noseweight must not exceed the value given on the trailer tow hitch and trailer identification plates. The lowest weight applies. ! Use a noseweight as close as possible to the maximum permissible noseweight. Do not use a noseweight of less than 50 kg, otherwise the trailer may come loose. Bear in mind that the payload and the rear axle load are reduced by the actual noseweight. Please note that when towing a trailer, PARKTRONIC (Y page 179), parking guidance (Y page 183) and Blind Spot Assist (Y page 190) are only available with limitations, or not at all. i The height of the ball coupling changes with the load of the vehicle. If necessary, use a trailer with a height-adjustable drawbar. Driving tips i Observe the notes on ESP® trailer stabilisation (Y page 70). In Germany, the maximum permissible speed for vehicle/trailer combinations depends on the type of trailer, and is either 80 km/h or 100 km/h. In some countries, higher maximum speeds are permissible for vehicle/ trailer combinations. Before beginning the journey, check the trailer's documents to see what the maximum permitted speed is. For certain Mercedes-Benz vehicles, the maximum permissible rear axle load is increased when towing a trailer. Refer to 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. The vehicle/trailer combination: Ris heavier restricted in its acceleration and gradient-climbing capability Rhas an increased braking distance Ris Trailer towing affected more by strong crosswinds more sensitive steering Rconsumes more fuel On long and steep downhill gradients, you must shift to a lower gear in good time, or on vehicles with automatic transmission, select the shift range 1, 2 or 3. Rdemands G WARNING Make sure that the ball coupling is engaged, either in its folded-out or folded-in position, and that the indicator lamp is off. Do not turn the release wheel when a trailer is coupled up. Otherwise, the trailer might detach. i This also applies if you have activated cruise control, SPEEDTRONIC or DISTRONIC PLUS. This will use the braking effect of the engine, so less braking will be required to maintain the 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. Driving tips a greater distance from the vehicle in front than when driving without a trailer. RAvoid braking abruptly. If possible, brake gently at first to allow the trailer to run on. Then, increase the braking force rapidly. RThe values given for gradient-climbing capabilities from a standstill refer to sea level. When driving in mountainous areas, note that the power output of the engine, and consequently the vehicle's gradientclimbing capability, decrease with increasing altitude.

Only restart the tyre pressure loss warning system when the defective wheel has been replaced with a new wheel. MOExtended tyres (tyres with run-flat characteristics) MOExtended tyres (tyres with run-flat characteristics) allow you to continue driving the vehicle even when one or more tyres lose all air pressure. MOExtended tyres may only be used in conjunction with the activated tyre pressure loss warning system or with the tyre pressure monitor. The maximum permissible distance which can be driven in run-flat mode depends on the load in the vehicle. It is 80 km if the vehicle is partially laden and 30 km if fully laden. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tyre pressure loss warning appears in the multifunction display. Battery G WARNING The handling characteristics of your vehicle deteriorate in run-flat mode, for example: Rwhen cornering braking Rwhen accelerating rapidly Adapt your driving style accordingly and avoid sudden changes in direction and sudden acceleration, as well as driving over obstacles (i.e. kerbs, potholes), and driving off-road. This is particularly the case when the vehicle is heavily laden. The maximum permissible distance that can be driven in run-flat mode depends to a large extent on the loads placed on the vehicle. It can be shorter due to high speeds, a heavy load, sudden changes in direction, the road surface condition, outside temperature, etc., or further if you drive carefully and conservatively. Do not continue to drive in run-flat mode if: Rwhen Ryou hear banging noises. vehicle starts to shake. Ryou see smoke and smell rubber. Rthe RESP® is intervening constantly. are tears in the sidewalls of the tyre. After driving in run-flat mode, you must have the wheel(s) checked for damage at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. The faulty tyre must be replaced in every case. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Rthere i When replacing one or all tyres, make sure that you only use tyres marked MOExtended and of the specified size for the vehicle. i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat properties, e.g. winter tyres. A TIREFIT kit can be obtained from a Mercedes-Benz Service Centre. Battery Important safety notes In order for the battery to achieve the maximum possible service life, it must always be sufficiently charged.

Countryspecific deviations are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-relevant systems and functions. i Please read the information on qualified specialist workshops (Y page 26). vehicle as soon as possible to check the wheels and tyres for damage. Hidden tyre damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the wheels and tyres examined at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. RWhen parking your vehicle, make sure that the tyres do not get deformed by the kerb or other obstacles. If it is necessary to drive over kerbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tyres, particularly the sidewalls, can get damaged. Wheels and tyres Important safety notes G WARNING Tyres, wheels or accessories which have not been approved by Mercedes-Benz for your vehicle or are not used as they should be, can impair driving safety. As a result, you could cause an accident. Before purchasing and using them, enquire about their suitability, legal stipulations and factory recommendations at a Mercedes-Benz Service Centre. Modification work on the brake system and wheels is not permitted, nor is the use of spacer plates or brake dust shields. This invalidates the General Operating Permit for the vehicle. i Further information about tyres and wheels can be obtained from any Mercedes-Benz Service Centre. Operation Notes on driving RWhile driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immediately. Stop the Notes on regularly inspecting wheels and tyres RRegularly check the wheels and tyres of your vehicle for damage (e.g. cuts, punctures, tears, bulges on tyres and deformation, cracks or severe corrosion on wheels), at least every 14 days, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tyre pressure. RRegularly check the tyre tread depth and the condition of the tread across the whole width of the tyre (Y page 337). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tyre surface. RAll wheels must have a valve cap to protect the valve against dirt and moisture. Do not fit anything onto the valve (such as tyre pressure monitoring systems) other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. RRegularly check the pressure of all the tyres including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 339). Winter operation G WARNING Bear in mind that: Rtyre grip decreases rapidly on wet roads when the tread depth is less than 3 mm. Thus, you should replace tyres that have insufficient tread. Rwinter tyres should be replaced when the tread depth is 4 mm or less as they no longer provide adequate grip. Rthe tread on a tyre may not wear evenly. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tyres. If necessary, turn the front wheels to full lock in order to inspect the tyre tread more easily. Otherwise, you could lose control of the vehicle and cause an accident due to the reduced grip of the tyres on the road. Notes on selecting, fitting and replacing tyres ROnly fit tyres and wheels of the same type and make. ROnly fit tyres of the correct size onto the wheels. RAfter fitting new tyres, run them in at moderate speeds for the first 100 km, as they only reach their full performance after this distance. RDo not drive with tyres which have too little tread depth, as this significantly reduces the traction on wet roads (aquaplaning). RReplace the tyres after six years at the latest, regardless of wear. This also applies to the emergency spare wheel/spare wheel. MOExtended tyres (tyres with run-flat characteristics) MOExtended tyres (tyres with run-flat characteristics) allow you to continue driving the vehicle even when one or more tyres lose all air pressure. MOExtended tyres may only be used in conjunction with the tyre pressure loss warning system or with the tyre pressure monitor and on wheels specifically tested by MercedesBenz. i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with the TIREFIT kit if you fit tyres that do not feature runflat properties, e.g. winter tyres. A TIREFIT kit can be obtained from a Mercedes-Benz Service Centre. You will find notes on driving with a flat tyre in the "Breakdown assistance" section (Y page 324). Winter operation Please bear the following in mind At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at a Mercedes-Benz Service Centre. Observe the notes in the "Changing a wheel" section (Y page 344). 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. M+S tyres At temperatures below +7 †, use winter tyres or all-season tyres. Both types of tyre are identified by the M+S marking. Z Wheels and tyres Tyre tread 337 Winter operation 338 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, as these tyres have been designed specifically for driving on snow. Use M+S tyres of the same make and tread on all wheels to maintain safe handling characteristics. Wheels and tyres G WARNING M+S tyres with a tread depth of less than 4 mm must be replaced. They are no longer suitable for winter use and can no longer provide sufficient grip. This could cause you to lose control of your vehicle and cause an accident. Always observe the maximum permissible speed specified for the M+S tyres you have fitted. If you fit M+S tyres which 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, e.g. at a Mercedes-Benz Service Centre. 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 176). When you have fitted the M+S tyres: X X Check the tyre pressures (Y page 339). Restart the tyre pressure loss warning system (Y page 340). G WARNING If you fit the spare wheel when driving with M +S tyres, bear in mind that driving stability will be impaired due to unstable cornering characteristics caused by the different tyres. You should therefore adapt your driving style and drive carefully. Have the spare wheel replaced at the nearest qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. Snow chains For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or that are of a corresponding standard of quality. If you intend to fit snow chains, please bear the following points in mind: Rit is not permissible to attach snow chains to all wheel-tyre combinations; see the information under "Wheel/tyre combinations" in the "Wheels and tyres" section. Rsnow chains must not be fitted to emergency spare wheels, e.g. a "Minispare" emergency spare wheel. Rfit snow chains only in pairs and only to the rear wheels. Observe the manufacturer's installation instructions. ! Vehicles with steel wheels: if you wish to fit snow chains to steel wheels, make sure that you remove the respective wheels' hubcaps first. The hubcaps may otherwise be damaged. Do not exceed the maximum permissible speed of 50 km/h. i You may wish to deactivate ESP® (Y page 67) when pulling away with snow chains fitted. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). Tyre pressure 339 Tyre pressure Tyre pressure specifications Instead of the complete tyre size, the rim diameter alone, for example R16, may be listed. Rim diameter : is part of the tyre size and can be found on the tyre sidewall. G WARNING Tyre pressure that is either too high or too low has a negative effect on the vehicle's driving safety, which could lead you to cause an accident. Therefore, you should regularly check the pressure of all the tyres, particularly prior to long trips, and correct the pressure as necessary. If a tyre size precedes a tyre pressure, the tyre pressure information following is only valid for that tyre size. To test tyre pressure, use a suitable pressure gauge. The outer appearance of a tyre does not permit any reliable conclusion about the tyre pressure. G WARNING Do not fit anything else to the tyre valve other than the standard valve cap. In particular, retrofitted tyre pressure monitors which are screwed on to the valve may overload it and cause it to fail. Due to their design, the valve Z Wheels and tyres You will find a table of tyre pressures for various operating conditions on the inside of your vehicle's fuel filler flap. Operation with emergency spare wheel: The applicable value for the emergency spare wheel is stated on the spare wheel and in the technical data section. Operation with a trailer: The applicable value for the rear tyres is the maximum tyre pressure value stated on the table inside the fuel filler flap. The table inside the fuel filler flap may state tyre pressures for different load conditions. These are defined in the table as different numbers of passengers and amounts of luggage. The actual number of seats may vary – for more information please refer to the vehicle's registration documents. If no other data is stated, the tyre pressures specified on the fuel filler flap apply for all tyres approved for this vehicle. 340 Tyre pressure is kept open continuously, which may lead to air loss. G WARNING Should the tyre pressure drop repeatedly: Rcheck the tyre for foreign bodies. Rcheck whether the wheel is losing air or the valve is leaking. sure that only a valve cap approved by Mercedes-Benz is fitted on the tyre valve. Tyre pressures that are too low have a negative effect on vehicle safety, which could lead you to cause an accident. Wheels and tyres Rmake If possible, only correct tyre pressures when the tyres are cold. The tyres are cold when the vehicle has been parked for at least three hours or has been driven less than 1.5 km. Depending on the ambient temperature, the speed you are driving at and the load on the tyres, the tyre temperature and thus the tyre pressure may change by approximately 10 kPa (0.1 bar/1.5 psi) per 10 †. Take this into account when checking the pressure of warm tyres and only correct it 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 the driving safety (e.g. by causing aquaplaning) Rcause i The tyre pressure values given for low loads are minimum values which offer you good ride comfort characteristics. However, you can also use the values given for higher loads. These are permissible and will not adversely affect the running of the vehicle. H Environmental note Check the tyre pressure regularly, at least every 14 days. Tyre pressure loss warning system Important safety 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. G WARNING The tyre pressure loss warning system does not warn you of an incorrectly set tyre pressure. The table on the inside of the fuel filler flap will help you decide whether the tyre pressures should be corrected. The tyre pressure loss warning system does not replace the need to regularly check your vehicle's tyre pressures, since 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. Do not make any sudden steering movements when doing so. 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).

As long as a clear allocation of the tyre pressure values to the individual wheels is not possible, the Tyre pressure monitor active display message is shown instead of the tyre pressure display. The tyre pressures are already being monitored. i If a spare wheel/emergency spare wheel is fitted, the system may continue to show the tyre pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the spare wheel/emergency spare wheel is fitted is not the same as the spare wheel/emergency spare wheel's current tyre pressure. Tyre pressure If the tyre pressure monitor detects a significant pressure loss on one or more tyres, a warning message is shown in the multifunction display. A warning tone also sounds and the tyre pressure warning lamp lights up in the instrument cluster. Each tyre that is affected by a significant loss of pressure is highlighted in the pressure display.

Z Wheels and tyres Tyre pressure monitor warning messages 343 344 Changing a wheel Changing a wheel Flat tyre The "Breakdown assistance" section (Y page 316) contains information and notes on how to deal with a flat tyre. It also provides instructions on changing a wheel or fitting the spare wheel or emergency spare wheel. Interchanging the wheels Wheels and tyres G WARNING Interchange the front and rear wheels only if they have the same dimensions, for example size, offset, etc. After every wheel interchange/change, have the tightening torque checked at a qualified specialist workshop that has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. The wheels could work loose if they are not tightened to a torque of 130 Nm. For safety reasons, Mercedes-Benz recommends that you only use wheel bolts of the correct size which have been approved for Mercedes-Benz vehicles. 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 5000 km to 10,000 km depending on the degree of tyre wear. Do not reverse the direction of tyre rotation. 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. ! 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. Always have the tyres changed at a qualified specialist workshop, e.g. a MercedesBenz Service Centre. Direction of rotation Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aquaplaning. You will only gain these benefits if the correct direction of rotation is observed. An arrow on the sidewall of the tyre indicates its correct direction of rotation. You may fit an emergency spare wheel/spare wheel against the direction of rotation. Observe the time restriction on use as well as the speed limitation specified on the emergency spare wheel/spare wheel. Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tyres against oil, grease, petrol and diesel. Cleaning the wheels G WARNING Do not use high-pressure cleaners with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tyres. You could otherwise damage the tyres and cause an accident. Wheel and tyre combinations Please bear the following in mind ! For safety reasons, Mercedes-Benz rec- ommends that you only use tyres and wheels which have been approved by Mercedes-Benz specifically for your vehicle. These tyres have been specially adapted for use with the control systems, such as ABS or ESP®, and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended (tyres with run-flat characteristics) RMO1 = Mercedes-Benz Original (only certain AMG tyres) Mercedes-Benz Original Extended tyres may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tyres, wheels or accessories tested and approved by Mercedes-Benz. Certain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely affected. In addition, when driving with a load, tyre dimension variations could cause the tyres to come into contact with the bodywork and axle components. This could result in damage to the tyres or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tyres, wheels or accessories other than those tested and approved. Further information about tyres, wheels and approved combinations can be obtained from any Mercedes-Benz Service Centre. ! Retreaded tyres are neither tested nor fit used tyres if you have no information about their previous usage. ! Large wheels: the lower the section width for a certain wheel size, the lower the ride comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and the risk of damage to the wheels and tyres as a result of driving over obstacles increases. i You will find a table of tyre pressures on the inside of your vehicle's fuel filler flap. For further information on tyre pressure, see (Y page 339). i Notes on the vehicle equipment – always fit the vehicle: Rwith tyres of the same size on a given axle (left/right) the same type of tyres at a given time (summer tyres, winter tyres, MOExtended tyres) Rwith i Overview of abbreviations used in the following tyre tables: RBA: both axles front axle RRA: rear axle RFA: In the following table, the wheel/tyre combinations are allocated to the vehicle models through variants, e.g. V1, V2 etc.: V1 C 18015 V2 C 220 CDI15 V3 C 25015, C 250 CDI15 V4 C 35015 V5 C 63 AMG recommended by Mercedes-Benz, since previous damage cannot always be detected on retreaded tyres.

Engine oil Please bear the following in mind The quality of engine oils is decisive for the function and service life of an engine. After extensive tests, Mercedes-Benz approves engine oils which correspond to the current technical standard. Therefore, only Mercedes-Benz approved engine oils may be used in Mercedes-Benz engines. Further information on tested and approved engine oils can be obtained from any Mercedes-Benz Service Centre. MercedesBenz recommends that you have the oil change carried out at a Mercedes-Benz Service Centre. Mercedes-Benz approval is indicated on the oil container by the inscription "MB Approval" and the corresponding designation, e.g. MB Approval 229.51. The table shows which engine oils have been approved for your vehicle. Petrol engines MB Approval 18026 C C 25026 229.3, 229.5, 229.51 C 35026 229.3, 229.5 C 63 AMG27 229.5 Diesel engines MB Approval Vehicles with a diesel particle filter C 220 CDI26 C 250 CDI26 228.51, 229.31, 229.51 You can call up an overview of approved engine oils on the Internet at http://bevo.mercedes-benz.com by entering the designation, e.g. 229.5. i If the engine oils listed in the table are not available, you may add a maximum of 1.0 l of the following engine oils, once only, until the next oil change: with a petrol engine28: MB Approval 229.1 or ACEA A3 Rvehicles with a diesel engine: MB Approval 229.1 or ACEA C3 Rvehicles Capacities The following values refer to an oil change including the oil filter. 26 BlueEFFICIENCY. 27 Restriction: 28 Restriction: only SAE 0W-40/SAE 5W-40 engine oils may be used. only SAE 0W-40/SAE 5W-40 engine oils may be used for AMG vehicles.

Do not use additives in engine oil. This could damage the engine. Technical data Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Engine oil selection is based on the respective outside temperatures and in accordance with the SAE classification (viscosity). The table below 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. Brake fluid G WARNING The brake fluid constantly absorbs moisture from the air; this lowers its boiling point. If the boiling point of the brake fluid is too low, vapour pockets may form in the brake system when the brakes are applied hard (e.g. when driving downhill). This would impair braking efficiency. You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Service Booklet. Only use brake fluid approved by MercedesBenz. Information about approved brake fluids can be obtained from any Mercedes-Benz Service Centre. i There is usually a notice in the engine compartment to remind you when the next brake fluid change is due. Coolant Important safety notes The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Ranti-corrosion protection protection Rraising the boiling point Rantifreeze i When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection. ! Only add coolant that has been premixed with the desired antifreeze protection. The engine could otherwise be damaged. Further information on coolants and on filling can be found in the Mercedes-Benz Specifications for Service Products, MB Approval 310.1, e.g. on the Internet at 29 BlueEFFICIENCY. 30 Including external oil cooler. Vehicle data ! Always use a suitable coolant mixture, even in countries where high temperatures prevail. Otherwise, the cooling system will not be sufficiently protected from corrosion, and the boiling point will be too low. If antifreeze/corrosion inhibitor is present in the correct concentration, the boiling point of the coolant will be around 130 †. The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine cooling system against freezing down to around -37 †. Rnot exceed 55% (antifreeze protection down to -45 † ); otherwise, heat will not be dissipated as effectively. If the vehicle has lost coolant, top it up with equal amounts of water and antifreeze/corrosion inhibitor. Mercedes-Benz recommends an antifreeze/corrosion inhibitor which has been approved for Mercedes-Benz. ! The engine cooling system is filled with coolant that must be renewed after 15 years, or after 250,000 km at the latest.
