Only use tires, wheels and accessories that have been specifically approved for your vehicle. Genuine Mercedes-Benz parts are subject to strict quality control. Every part has been specifically developed, manufactured or selected for and adapted to Mercedes-Benz vehicles. Only genuine Mercedes-Benz parts should therefore be used. More than 300,000 different genuine Mercedes-Benz parts are available for Mercedes-Benz models.

In situations like this, the body, the undercarriage, chassis parts, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, no longer withstand the strain they are designed to. If the underbody paneling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody paneling. If these materials come in contact with hot parts of the exhaust system for an extended period, they can catch fire. Have the vehicle checked and repaired immediately at a qualified specialist workshop. If on continuing your journey you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, visit a qualified specialist workshop.

SRS (Supplemental Restraint System) Introduction SRS consists of: RThe 6 SRS warning lamp RAir bags RAir bag control unit (with crash sensors) REmergency Tensioning Devices 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. 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. The SRS components are in operational readiness when the 6 SRS warning lamp goes out while the engine is running.

RDo not change or remove any component or part of the SRS. RDo not install additional trim material, seat covers, badges, etc. over the steering wheel hub, front-passenger front air bag cover, outer sides of the seat backrests, door trim panels, or door frame trims. RDo not install additional electrical/ electronic equipment on or near SRS components and wiring. RKeep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.). RDo not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed. RAir bag system components will be hot after an air bag has inflated. Do not touch them. RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat. RImproper repair work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. RFor your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center. RGiven the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment. If you sell your vehicle, Mercedes-Benz strongly recommends that you inform the subsequent owner that the vehicle is equipped with SRS. Also, refer them to the applicable section in the Operator's Manual. Air bags Important safety notes

As the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag, as it inflates with great force instantaneously: Rsit with the seat belt fastened correctly and in a position that is as upright as possible with your back against the backrest. Rmove the driver's seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver's chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm). You should be able to accomplish this by adjusting the seat and steering wheel. If you have any difficulties, please contact an authorized Mercedes-Benz Center. Rdo not lean your head or chest close to the steering wheel or dashboard. Ronly hold the steering wheel on the outside. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury if the driver front air bag inflates. Radjust the front-passenger seat as far back as possible from the dashboard when the seat is occupied. Roccupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious or fatal injuries should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint or booster seat recommended for the size and weight of the child. Failure to follow these instructions can result in severe injuries to you or other occupants. If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this Operator's Manual.

It is important to your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags will continue to provide supplemental crash protection for occupants . Front air bags The front air bags increase protection for the driver's and front-passenger's head and chest. Driver's air bag : deploys in front of the steering wheel; front-passenger front air bag ; deploys in front of and above the glove box. They are deployed: Rin the event of certain frontal impacts Rif the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rif the seat belt is fastened Rindependently of other air bags in the vehicle Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. In the first deployment stage, the front air bag is filled with enough propellant gas to reduce the risk of injuries. The front air bag is fully deployed if a second deployment threshold is exceeded within a few milliseconds. The deployment of the front-passenger front air bag is also influenced by the weight category of the front passenger, which is determined by the Occupant Classification System (OCS) (Y page 47). The lighter the passenger-side occupant, the higher the vehicle deceleration rate required (predicted at the start of the impact) for second stage inflation of the front-passenger front air bag. In the second stage, the front air bags are inflated with the maximum amount of propellant gas available. The front air bags are not deployed in situations where a low impact severity is predicted. You will then be protected by the fastened seat belt. The front-passenger front air bag will only be deployed if: Rthe system, based on the OCS weight sensor readings, detects that the front- passenger seat is occupied Rthe 45 indicator lamp on the center console is not lit (Y page 47) Rthe air bag control unit predicts a high- impact severity. Driver's knee bag Driver's knee bag : increases the driver's protection against: Rknee injuries Rthigh injuries Rlower leg injuries Driver's knee bag : deploys under the steering column.

Belt warning for the driver and front passenger Regardless of whether the driver's and front- passenger seat belts have already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. It then goes out if the driver and the front passenger have already fastened their seat belts. If the driver's seat belt is not fastened when the engine is started, an additional warning tone will sound. This warning tone stops after a maximum of six seconds or once the driver's seat belt is fastened. If after six seconds the driver or front passenger have not fastened their seat belts and the doors are closed, the 7 seat belt warning lamp lights up: Runtil the driver's or front passenger's seat belt is fastened Rif a vehicle speed of 15 mph (25 km/h) is exceeded, a warning tone also sounds with increasing intensity for a maximum of 60 seconds or until the driver or front- passenger seat belt has been fastened. If the driver/front passenger unfasten their seat belt while the vehicle is in motion, the 7 seat belt warning lamp lights up and a warning tone sounds again. The warning tone ceases even if the driver or front-passenger seat belt has still not been fastened after 60 seconds. The 7 seat belt warning lamp stops flashing but remains illuminated. After the vehicle comes to a standstill, the warning tone is reactivated and the 7 seat Occupant safety 57 Safety

belt warning lamp flashes again if the vehicle speed again exceeds 15 mph (25 km/h). The 7 seat belt warning lamp only goes out if: Rboth the driver and the front passenger have fastened their seat belts. or Rthe vehicle is stationary and a door is open. i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belts" (Y page 242). Emergency Tensioning Devices, seat belt force limiters The seat belts for the front seats and rear outer seats are equipped with ETDs and seat belt force limiters. The ETDs tighten the seat belts in an accident, pulling them close against the body. The ETDs do not correct incorrect seat positions or incorrectly fastened seat belts. The ETDs do not pull vehicle occupants back towards the backrest. When triggered, the seat belt force limiters help to reduce the peak force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags. These take on a part of the deceleration force. They take on a part of the deceleration force, resulting in the force exerted on the occupant being distributed over a greater area. The ETDs can only be activated when: Rthe ignition is switched on Rthe restraint systems are operational; see "SRS warning lamp" (Y page 41). Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front Rthe front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side The ETDs on the outside seats in the rear compartment are triggered independently of the lock status of the seat belts. The Emergency Tensioning Devices are triggered depending on the type and severity of an accident, if: Rin the event of a head-on or rear-end collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact Rin the event of a side impact, the vehicle decelerates or accelerates rapidly in a lateral direction on the side opposite the impact If the ETDs 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.

PRE-SAFE® Brake can help you to minimize the risk of a 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. Starting at a speed of around 4 mph (7 km/h), this function warns you if you very quickly approach a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action provided it is safe to do so. From a speed of approximately 4 mph (7 km/h), if the driver and front passenger have fastened their seat belts, PRE-SAFE® Brake can brake the vehicle automatically at speeds up to approximately 124 mph (200 km/h). Due to the nature of the system, particularly complicated driving conditions may cause unnecessary warnings or the unnecessary intervention of PRE-SAFE® Brake. You can prevent the intervention of the PRE- SAFE® Brake at any time by: Rdepressing the accelerator pedal further Ractivating kickdown Rreleasing the brake pedal The braking action of PRE-SAFE® Brake is ended automatically if: Ryou maneuver to avoid the obstacle. Rthere is no longer any danger of a rear-end collision. Rthere is no longer an obstacle detected in front of your vehicle. At speeds of up to approximately 40 mph (70 km/h), PRE-SAFE® Brake can also detect stationary objects. Examples of stationary objects are stopped or parked vehicles. If you approach an obstacle and PRE-SAFE® Brake detects a risk of a collision, the system will alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventative passenger protection measures (PRE-SAFE®) are activated (Y page 52). If the risk of collision with the vehicle in front remains and you do not brake, take evasive action or accelerate significantly, automatic braking may be performed up to a level of emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided.

Useful information i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions. i Read the information on qualified specialist workshops: (Y page 25). Overview of climate control systems Important safety notes Observe the settings recommended on the following pages. The windows could otherwise fog up. To prevent the windows from fogging up: Rswitch off climate control only briefly Rswitch on air-recirculation mode only briefly Rswitch on the cooling with air dehumidification function Rswitch on the defrost windshield function briefly, if required Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control can only be operated when the engine is running. Optimum operation is only achieved with the side windows and roof closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 136). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 86). 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 Maintenance Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet. i It is possible that the dehumidification function of the climate control system may be activated automatically an hour after the SmartKey has been removed. The vehicle is ventilated for 30 minutes. 126 Overview of climate control systems Climate control

Useful information i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions. i Read the information on qualified specialist workshops: (Y page 25). Notes on breaking-in a new vehicle Important safety notes New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. The first 1,000miles (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. RYou should therefore drive at varying vehicle and engine speeds for the first 1,000 miles (1,500 km). RIdeally, for the first 1,000 miles (1,500 km), drive in program E (for AMG vehicles drive program C). RAvoid heavy loads, e.g. driving at full throttle, during this period. RChange gear in good time, before the tachometer needle is Ô of the way to the red area of the tachometer. RDo not manually shift to a lower gear to brake the vehicle. 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 1,000 miles (1,500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. Additional breaking-in notes for AMG vehicles: RDo not drive faster than 85 mph (140 km/h) for the first 1000 miles (1500 km). ROnly allow the engine to reach a maximum engine speed of 4,500 rpm briefly. RChange gear in good time. i You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced. i Always observe the respective speed limits. AMG vehicles with self-locking rear axle differential Your vehicle is equipped with a self-locking differential on the rear axle. Change the oil after a breaking-in period of 2,000 miles (3,000 km) to improve protection of the rear axle differential. This oil change prolongs the service life of the differential. Have the oil change carried out at a qualified specialist workshop. Driving Important safety notes

Wet roads If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after 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 If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance. RBrake occasionally to remove any possible salt residue. Make sure that you do not endanger other road users when doing so. RCarefully depress the brake pedal and the beginning and end of a journey. RMaintain a greater distance to the vehicle ahead. Servicing the brakes ! If the red brake warning lamp lights up in the instrument cluster and you hear a warning tone while the engine is running, the brake fluid level may be too low. Observe additional warning messages in the multifunction display. The brake fluid level may be too low due to brake pad wear or leaking brake lines. Have the brake system checked immediately. This work should be carried out at a qualified specialist workshop. All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Consult a qualified specialist workshop to arrange this. Have brake pads installed and brake fluid replaced at a qualified specialist workshop. ! Vehicles with 4MATIC: function or performance tests may only be carried out on a 2-axle dynamometer. If you are planning to have the vehicle tested on such a dynamometer, contact an authorized Mercedes-Benz Center to obtain further information first. Otherwise, you could damage the drive train or the brake system. ! Vehicles with 4MATIC: as the ESP® system operates automatically, the engine and the ignition must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) while the parking brake is being tested on a brake dynamometer.

Brake fluid which has not been approved for Mercedes-Benz vehicles or which is not of an equivalent quality could affect your vehicle's operating safety. High-performance brake system for AMG vehicles The high-performance brake system is installed only on the C 63 AMG. 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 and tear on individual brake system components, e.g. brake pads/linings or discs, depends on: Rthe individual driving style Rthe 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 authorized Mercedes-Benz Center. New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and braking accordingly during this break-in period. Excessive heavy braking results in correspondingly high brake wear. Observe the brake wear warning lamp in the instrument cluster and note any brake status messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. Driving on wet roads Hydroplaning If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if: Ryou drive at low speeds. Rthe tires have adequate tread depth. For this reason, in the event of heavy rain or in conditions in which hydroplaning may occur, you must drive in the following manner: Rlower your speed. Ravoid ruts. Rbrake carefully. Driving on flooded roads ! Do not drive through flooded areas. Check the depth of any water before driving through it. Drive slowly through standing water. Otherwise, water may enter the vehicle interior or the engine compartment. This can damage the electronic components in the engine or the automatic transmission.

Parking Guidance Important safety notes Parking Guidance is an electronic parking aid with ultrasound. 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). Parking Guidance is only an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. When maneuvering, parking or pulling out of a parking space, make sure that there are no persons, animals or objects in the area in which you are maneuvering.

G Warning

Use Parking Guidance for parking spaces: Rthat are parallel to the direction of travel Rthat are on straight roads, not bends Rthat are on the same level as the road, i.e. not on the pavement, for example. Parking Guidance may not detect flat curbs Parking tips: ROn narrow roads, drive as close to the parking space 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 180) 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 mounted. RMake sure that the tire 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 lead you across or onto the curb. If necessary, cancel the parking procedure with Parking Guidance. ! If unavoidable, you should drive over obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires. Detecting parking spaces : Detected parking space on the left ; Parking symbol = Detected parking space on the right Parking Guidance is automatically activated when you drive forwards. The system is operational at speeds of up to approximately 22 mph (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 19 mph (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. Parking Guidance will only detect parking spaces: Rthat are parallel to the direction of travel Rthat are at least 5 ft (1.5 m) wide Rthat are at least 4.3 ft (1.3 m) longer than your vehicle A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it.

Problems when programming If you are experiencing problems programming the integrated garage door opener on the rear-view mirror, take note of the following instructions: RCheck the transmitter frequency of garage door drive remote control A. This can usually be found on the back of the remote control. The integrated garage door opener is compatible with devices that have units which operate in the frequency range of 280to 433MHz. RReplace the batteries in garage door remote control A. This increases the likelihood that garage door remote control A will transmit a strong and precise signal to the integrated garage door opener in the rear-view mirror. RWhen programming, hold remote control A at varying distances and angles from the button that you are programming. Try various angles at a distance between 2and 12 inches (5to 30 cm) or at the same angle but at varying distances. RIf another remote control for the same garage door drive is available, repeat the same programming steps with this remote control. Before performing these steps, make sure that new batteries have been installed in garage door drive remote control A. RNote that some remote controls only transmit for a limited amount of time (the indicator lamp on the remote control goes out). Press button B on remote control A again before transmission ends. RAlign the antenna cable of the garage door opener unit. This can improve signal reception/transmission.

Selecting, mounting and replacing tires ROnly mount tires and wheels of the same type and make. Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics)" section (Y page 297) ROnly mount tires of the correct size onto the wheels. RAfter mounting new tires, break them in at moderate speeds for the first 60 miles (100 km), as they only reach their full performance after this distance. RDo not drive with tires which have too little tread depth, as this significantly reduces the traction on wet roads (hydroplaning). RReplace the tires after six years at the latest, regardless of wear. This also applies to the spare wheel/emergency spare wheel. The service life of tires depends on the following factors amongst other things: RDriving style RTire pressure RDistance covered MOExtended tires (tires with run-flat properties) MOExtended tires (tires with run-flat properties) allow you to continue driving your vehicle even if one or more tires are entirely deflated. MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tires in the event of a flat tire can be found in the "Breakdown assistance" section (Y page 297). Winter operation Points to remember Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 334). Driving with summer tires At temperatures below 45 ‡ (+7 †), summer tires lose elasticity and therefore traction and braking power. Change the tires on your vehicle to M+S tires. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage. M+S tires

Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar Ron the tire pressure label on the fuel filler flap Rin the "Tire pressure information" section Checking tire pressures manually To determine and set the correct tire pressure, proceed as follows: X Remove the valve cap of the tire that is to be checked. X Press the tire pressure gauge securely onto the valve. X Read the tire pressure and compare it with the recommended value on the Tire and Loading Information placard on the B-pillar on the driver's side of your vehicle. X If necessary, increase the tire pressure to the recommended value (Y page 313). X If the tire pressure is too high, release air by pressing down the metal pin in the valve using the tip of a pen, for example. Then, check the tire pressure again using the tire pressure gauge. X Screw the valve cap onto the valve. X Repeat these steps for the other tires. Tire pressure loss warning system (Canada only) General notes While the vehicle is in motion, the tire pressure loss warning system monitors the set tire pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tire. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display. You can recognize the tire pressure loss warning by the Run Flat Indicator Active Press 'OK' to Restart message which appears in the Service menu of the multifunction display. Further information on the message display can be found under "Restarting the tire pressure loss warning system" section (Y page 318). Important safety notes The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 313). The tire pressure loss warning system does not replace the need to regularly check your vehicle's tire pressures, since an even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system. The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. The function of the tire pressure loss warning system is limited or delayed if: Rsnow chains are mounted on your vehicle's tires. 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 driving with a heavy load (in the vehicle or on the roof).

The tire pressure values stored at the last restart will continue to be monitored. Tire pressure monitor General notes If a tire pressure monitor is installed, the vehicle's wheels have sensors that monitor the tire pressures in all four tires. The tire pressure monitor warns you if the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct sensors are installed to all wheels. Information on tire pressures is displayed in the multifunction display. After a few minutes of driving, the current tire pressure of each tire is shown in the multifunction display. Example: current tire pressure display Important safety notes It is the driver's responsibility to set the tire pressure to that recommended for cold tires which is suitable for the operating situation (Y page 313). Note that the correct tire pressure for the current operating situation must first be taught-in to the tire pressure monitor. If there is a substantial loss of 318 Tire pressure Wheels and tires

pressure, the warning threshold for the warning message is aligned to the reference values taught-in. Restart the tire pressure monitor after adjusting the pressure of the cold tires (Y page 320). The current pressures are saved as new reference values. As a result, a warning message will appear if the tire pressure drops significantly. The tire pressure monitor does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 313). The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. The tire pressure monitor has a yellow warning lamp in the instrument cluster for indicating pressure loss/malfunctions (USA) or pressure loss (Canada). Whether the warning lamp flashes or lights up indicates whether a tire pressure is too low or the tire pressure monitor is malfunctioning: Rif the warning lamp is lit continuously, the tire pressure on one or more tires is significantly too low. The tire pressure monitor is not malfunctioning. RUSA only: if the warning lamp flashes for around a minute and then remains lit constantly, the tire pressure monitor is malfunctioning.

If the tire pressure monitor is malfunctioning, it may take more than ten minutes for the tire pressure warning lamp to inform you of the malfunction by flashing for approximately one minute and then remaining lit. When the malfunction has been rectified, the tire pressure warning lamp goes out after a few minutes of driving. i The tire pressure values indicated by the on-board computer may differ from those measured at a gas station with a pressure gauge. The tire pressures shown by the on- board computer refer to those measured at sea level. At high altitudes, the tire pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tire pressures. i The operation of the tire pressure monitor can be affected by interference from radio transmitting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.

X Press the 9 or : button to select Tire Pressure. X Press the a button. The current tire pressure of each tire is shown in the multifunction display. If the vehicle has been parked for over 20 minutes, the Tire pressures will be displayed after driving a few minutes message appears. After a teach-in process, the tire pressure monitor automatically detects new wheels or new sensors. As long as a clear allocation of the tire pressure value to the individual wheels is not possible, the Tire Pressure Monitor Active display message is shown instead of the tire pressure display. The tire pressures are already being monitored. i If a spare wheel/emergency spare wheel is mounted, the system may continue to show the tire 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 tire is mounted is not the same as the spare wheel/emergency spare wheel's current tire pressure. Tire pressure monitor warning messages If the tire pressure monitor detects a significant pressure loss on one or more tires, a warning message is shown in the multifunction display. A warning tone also sounds and the tire pressure warning lamp lights up in the instrument cluster. Each tire that is affected by a significant loss of pressure is highlighted with a color. If the following message appears in the multifunction display: Correct Tire Pressure: X Check the tire pressure on all four wheels and correct it if necessary. i If the wheel positions on the vehicle are rotated, the tire pressures may be displayed for the wrong positions for a short time. This is rectified after a few minutes of driving, and the tire pressures are displayed for the correct positions. Restarting the tire pressure monitor When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring.

The maximum permissible load is vehicle-specific and may deviate from the data shown here. The maximum permissible load that applies for your vehicle can be found on your vehicle's Tire and Loading Information placard. X Specification for maximum permissible load : is listed on the Tire and Loading Information placard: "The combined weight of occupants and cargo should never exceed XXX kilograms or XXX lbs." The gross weight of all vehicle occupants, load, luggage and trailer load/noseweight (if applicable) must not exceed the specified value.

Determining the correct load limit Step-by-step instructions The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle Safety Act of 1966". X Step 1: Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s Tire and Loading Information placard. X Step 2: Determine the combined weight of the driver and passengers that will be riding in your vehicle. X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or XXX lbs. 322 Loading the vehicle Wheels and tires

X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1 400 - 750 (5 x 150) = 650 lbs). X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. X Step 6 (if applicable): If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Refer to this Operator's Manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (Y page 325). Loading the vehicle 323 Wheels and tires

Permissible gross vehicle weight: the gross weight of the vehicle, all passengers, load and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight. Gross axle weight rating: the maximum permissible weight that can be carried by one axle (front or rear axle). To ensure that your vehicle does not exceed the maximum permissible values (gross vehicle weight and maximum gross axle weight rating), have your loaded vehicle (including driver, occupants, cargo, and full trailer load if applicable) weighed on a suitable vehicle weighbridge. Trailer load/noseweight The trailer load/noseweight affects the gross weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load along with occupants and luggage. The trailer load/noseweight is usually approximately 10% of the gross weight of the trailer and its load. Your Mercedes-Benz has been designed primarily to carry passengers and their luggage.

Gasoline Fuel grade ! Do not use diesel to refuel vehicles with a gasoline engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. The repair costs are high. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely. ! You should only refuel with unleaded premium-grade gasoline as this avoids damaging the catalytic converter. If engine running problems are apparent, have the cause checked immediately and repaired. Excess unburned fuel can otherwise enter the catalytic converter, leading to overheating and possibly causing a fire. ! To ensure the longevity and full performance of the engine, only premium- grade unleaded gasoline may be used. If there is no premium-grade unleaded gasoline available and regular unleaded gasoline must be used, please observe the following precautions: Ronly fill the fuel tank to half full with regular unleaded gasoline and fill the rest with premium-grade unleaded gasoline as soon as possible. Rdo not drive at the maximum speed. Ravoid sudden acceleration. Rif the vehicle is carrying a light load, e.g. two passengers without luggage, do not allow the engine to rev above 3000 rpm. Rif the vehicle is fully loaded or is being operated in mountainous terrain, do not depress the accelerator pedal further than Ô of the pedal travel. Only refuel using premium-grade unleaded gasoline with a minimum octane rating of 91. Reformulated Gasoline (RFG) and/or unleaded gasoline with additives can be used. The concentration of additives in the fuel, however, must not exceed 10%, e.g.: REthanol

can be obtained from any authorized Mercedes-Benz Center. One of the main problems of poor fuel quality is the forming of deposits that are created during the gasoline combustion process. Mercedes-Benz recommends that you use branded fuels that have additives. If you use fuels without these additives over a longer period of time, carbon deposits may build up. These deposits form at the inlet valves and in the combustion chamber in particular. This could lead to engine problems, e.g.: Rlonger engine warm-up phase Runeven idle Rengine noise Rmisfiring Rloss of power Carbon deposits may form if the availability of gasoline with relevant additives is insufficient (in certain regions). In this case, Mercedes-Benz recommends additives approved for use in Mercedes-Benz vehicles; see http://bevo.mercedes-benz.com. For a list of approved products, consult an authorized Mercedes-Benz Center. Comply with the instructions for use on the product label. Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine. Flexible Fuel vehicles Important safety notes

Low outside temperatures If the outside temperature is below 32 ‡ (0 †), the starting procedure can take noticeably longer when operating with E85 fuel. E85 fuel is not suitable for use at outside temperatures under -4 ‡ (-20 †). Engine oil General notes ! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment. When handling engine oil, observe the important safety notes on service products (Y page 347). The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center. Or visit the website http://bevo.mercedes-benz.com. The table shows which engine oils have been approved for your vehicle. Model Engine model

Additives ! Do not use any additives in the engine oil. This could damage the engine. 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. Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside temperatures. The table shows you which SAE classifications are to be used. The low- temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification. Brake fluid

Otherwise, the engine cooling system is not sufficiently protected from corrosion and overheating. When handling coolant, observe the important safety notes on service products (Y page 347). The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Rcorrosion protection Rantifreeze protection Rraising the boiling point If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant during operation is approximately 266 ‡ (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 approximately -35 ‡ (-37 †). Rnot exceed 55% (antifreeze protection down to -49 ‡ [-45 †]). Otherwise, heat will not be dissipated as effectively. If the vehicle has lost coolant, add equal amounts of water and antifreeze/corrosion inhibitor. Mercedes-Benz recommends an antifreeze/ corrosion inhibitor concentrate in accordance with MB Specifications for Service Products 310.1. The coolant is checked with every maintenance interval at a qualified specialist workshop. i When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection.
