Further information on stowing the collapsible spare wheel (Y page 326). i When you are driving with the collapsible
spare wheel mounted, the tire pressure loss warning system or the tire pressure monitor cannot function reliably. Only restart the tire pressure loss warning system/tire pressure monitor when the defective wheel has been replaced with a new wheel. Vehicles with tire pressure monitor: all mounted wheels must be equipped with functioning sensors and the defective wheel should no longer be in the vehicle.
MOExtended run-flat system The MOExtended run-flat system allows you to drive on even if there is a complete loss of pressure in one or more tires. The MOExtended run-flat system may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitor. The maximum permissible distance which can be driven in run-flat mode depends on the cargo in the vehicle. You can drive 50 miles (80 km) if the vehicle is partially laden and 18 miles (30 km) if it is fully laden. The maximum permissible distance which can be driven in run-flat mode is counted from

Version: 3.0.3.6338 Battery
the moment the tire pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 50 mph(80 km/h). G Warning! The handling characteristics of your vehicle deteriorate in run-flat mode, for example: Rwhen cornering Rwhen 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. curbs, 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 cargo, 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: Ryou hear banging noises. Rthe vehicle starts to shake. Ryou see smoke and smell rubber. RESP® is intervening constantly. Rthere are tears in the sidewalls of the tire. 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 tire must be replaced in every case. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.
i When replacing one or all tires, make sure
that you only use tires marked
MOExtended and of the specified size for the vehicle.
i Vehicles featuring the MOExtended run- flat system are not equipped with TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with the TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. You can obtain a TIREFIT kit from an authorized Mercedes- Benz Center, for example.
Battery Important safety notes In order for the battery to achieve the maximum possible service life, it must always be sufficiently charged. ! Have the battery checked regularly at a

Important safety notes
Vehicle equipment
i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.
Important safety notes
Contact an authorized Mercedes-Benz Center if you require information on tested and recommended tires and wheels for summer and winter driving. Advice on purchasing and caring for tires is also available there. G Warning Replace rims or tires with the same designation, manufacturer and type as shown on the original part. For further information contact an authorized Mercedes-Benz Center. If incorrectly sized rims and tires are mounted, the wheel brakes or suspension components can be damaged. Also, the operating clearance of the wheels and the tires may no longer be correct. G Warning Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them. When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Retreaded tires are not tested or recommended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used.
G Warning If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle appears unsafe, have the vehicle towed to the nearest authorized Mercedes-Benz Center or tire dealer for repairs. G Warning Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You might lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build- up and possibly a fire.
! For safety reasons, Mercedes-Benz recommends that you only use tires, wheels and accessories which have been approved by Mercedes-Benz specifically for your vehicle. These tires 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
(tires with run-flat characteristics)
RMO1 = Mercedes-Benz Original (AMG) Only use Mercedes-Benz Original Extended tires on wheels that have been specifically approved by Mercedes-Benz. If you use other tires, wheels and accessories, Mercedes-Benz cannot accept any responsibility for damage that may result from this. Further information about tires, wheels and approved combinations can be obtained from any authorized Mercedes-Benz Center.

Version: 3.0.3.6Maintenance and care of wheels and tires
351
Directives to be observed
ROnly mount tires and wheels of the same
type and make.
ROnly mount tires of the correct size onto
the wheels.
RAfter mounting new tires, run them in at
moderate speeds for the first 60 miles (100 km) as they only reach their full performance after this distance.
RDo not use tires until they are excessively
worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 in (3 mm).
RIf the vehicle is heavily laden, check the tire
pressure and adjust it if necessary.
RWhen parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, can get damaged.
Maintenance and care of wheels and tires Checking wheels and tires G Warning Regularly check the tires for damage. Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them.
RRegularly check the wheels and tires of
your vehicle for damage (e.g. cuts, punctures, tears, bulges on tires and deformation or cracks or severe corrosion on wheels), at least once a month, as well as after driving off-road or on rough roads.
Damaged wheels can cause a loss of tire pressure.
RRegularly check the tire tread depth and
the condition of the tread across the whole width of the tire (Y page 351). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.
RAll wheels must have a valve cap to protect the valve against dirt and moisture. Do not install anything on the valve (such as tire 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 tires including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 352).
Service life of tires The service life of tires depends on the following factors amongst other things: Rdriving style Rtire pressure Rmileage Replace the tires after six years at the latest, regardless of wear. This also applies to the emergency spare wheel/spare wheel.
Tire tread G Warning Although the applicable federal motor vehicle safety laws consider a tire to be worn when the tread wear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recommend that you do not allow your tires to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced.

Version: 3.0.3.6352 Tire pressures
Depending upon the weather and/or road surface (conditions), the tire traction varies widely.
Do not use tires until they are excessively worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 in (3 mm). Tread wear indicators (TWI) are required by law. Six indicators are positioned over the tire tread. They are visible as soon as a tread depth of approximately 1/16 in (1.6 mm) is reached. If this is the case, the tire is so worn that it must be replaced. The recommended tread depth for summer tires is at least 1/8 in (3 mm). The recommended tread depth for winter tires is at least 1/6 in (4 mm).
Bar marking : for tread wear is integrated into the tire tread.
Storing tires Store tires that are not being used in a cool, dry and preferably dark place. Protect the tires from contact with oil, grease and fuel.
Cleaning tires G Warning Do not use power washers with circular jet nozzles (concentrated-power jets) to clean your vehicle, especially for cleaning tires. You
could otherwise damage the tires and cause an accident.
Tire pressures Recommended tire pressures G Warning Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure.
You will find a table of recommended tire pressures on the Tire and Loading Information placard on the B-pillar on the driver's side (Y page 360). You will find a table of tire pressures for various operating conditions on the inside of your vehicle's fuel filler flap. Use a suitable pressure gauge. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitor, the tire pressure can be checked using the on-board computer. G Warning Should the tire pressure drop repeatedly:

Rcheck the tire for foreign bodies. Rcheck whether the wheel is losing air or the
valve is leaking.
Rmake sure that only a valve cap approved by Mercedes-Benz is installed on the tire valve.
Tire pressures that are too low have a negative effect on vehicle safety, which could lead you to cause an accident.
Only correct tire pressures when the tires are cold. The tires are cold when the vehicle has been parked for at least three hours or driven for less than 1 mile (1.6 km). The tire temperature changes depending on the outside temperature, the vehicle speed and the tire load. If the tire temperature changes by 18 ‡ (10 †), the tire pressure changes by approximately 10 kPa (0.1 bar/1.5 psi). Take this into account when checking the pressure of warm tires and only correct the tire pressure if it is too low for the current operating conditions. If you check the tire pressure when the tires are warm, the reading will be higher than if the tires were cold. This is normal. Do not reduce the tire pressure to the value specified for cold tires. The tire pressure would otherwise be too low. Observe the recommended tire pressure specifications for cold tires on the Tire and Loading Information placard on the B-pillar on the driver's side. i The specifications given on the following Tire and Loading Information placard are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications for your vehicle can be found on the Tire and Loading Information placard of your vehicle.
You will find recommended tire pressure specifications : for cold tires and for a fully loaded vehicle on the Tire and Loading Information placard. The tire pressure specifications apply to tires which are installed at the factory.
Important notes on tire pressures G Warning If the tire pressure drops repeatedly, check the tires for punctures from foreign objects and/or whether air is leaking from the valves or from around the rim.
The temperature and pressure of the tires increase when the vehicle is in motion. This is dependent on the driving speed and the load. If you wish to drive at high speeds of 100 mph (160 km/h) or higher when this is allowed, use the tire pressure table on the inside of the fuel filler flap to set the correct tire pressures when the wheels are cold. If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure. For more information, contact a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. i Ride comfort may be affected if the tire pressure is adjusted to the recommended value for speeds of over 100 mph(160 km/h).

in handling or steering problems, or brake failure.
Check the tire pressure at least once a month. Only check and correct tire pressures when the tires are cold (Y page 352).
Checking the tire pressures manually In order to determine and adjust the tire pressures, proceed as follows: X Remove the valve cap of the tire you wish
to check.
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 352).
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 the steps for the other tires.
Tire pressure loss warning system (Canada only) Important safety 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.

G Warning If the Check Tire Pressure Soon message appears in the multifunction display, one or more tires are significantly underinflated. Stop the vehicle as soon as possible and inflate the tires to the pressure specified on the vehicle's Tire and Loading Information placard or (where available) in the tire pressure table. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Check all tires when cold, including the spare tire, at least once a month. The tires should be inflated to the recommended pressure. This information can be found: Ron the Tire and Loading Information placard
on the B-pillar on the driver's side or
Rin the table for the tire pressure on the
inside of the fuel filler flap G Warning! The tire pressure loss warning system does not provide a warning for wrongly selected tire inflation pressures. Always adjust tire inflation pressure according to the Tire and Loading Information placard on the driver's door B-pillar or on the tire inflation pressure label located on the inside of the fuel filler flap. The tire pressure loss warning system does not replace regular checks of the tire inflation pressures since a gradual pressure loss in more than one tire cannot be detected by the tire pressure loss warning system. The tire pressure loss warning system is not able to issue a warning due to a sudden dramatic loss of tire inflation pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully applying the brakes and avoiding abrupt steering maneuvers.
The function of the tire pressure loss warning system is limited or delayed if: Rsnow chains are mounted on your vehicle. 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 cargo (in the
vehicle or on the roof).
Restarting the tire pressure loss warning system Restart the tire pressure loss warning system if you have: Rchanged the tire pressure Rchanged the wheels or tires Rmounted new wheels or tires X Before restarting, refer to the Tire and
Loading Information placard on the B-pillar on the driver's side or the tire pressure table on the inside of the fuel filler flap to ensure the tire pressure in all four tires is set correctly for the current operating conditions.
X Observe the notes in the section on tire
pressures (Y page 352). G Warning The tire pressure loss warning system can only give reliable warnings if you have set the correct tire pressure. If an incorrect tire pressure is set, these incorrect values will be monitored. A tire with insufficient pressure results in vehicle instability when driving, thus increasing the risk of an accident.

Tire pressure monitoring system Important safety notes If a tire pressure monitor is installed, the vehicle's wheels have sensors installed that monitor the tire pressures in all four tires. The tire pressure monitor warns you when the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct wheel electronics units are installed in all wheels.
Tire pressures
357
The tire pressure monitor has a yellow warning lamp in the instrument cluster for indicating pressure loss/malfunctions (USA) or pressure loss (Canada). Depending on how the warning lamp flashes or lights up, a tire pressure that is too low or a malfunction in the tire pressure monitor is displayed: 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
60 seconds and then remains lit constantly, the tire pressure monitor is malfunctioning. G Warning Each tire, including the spare (if provided), should be checked at least once a month when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver’s door B- pillar or the tire inflation pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or the tire inflation pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not

reached the level to trigger illumination of the TPMS low tire pressure telltale. USA only: Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the tire pressure monitoring system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is lit, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
i USA only:
If the tire pressure monitor is malfunctioning, it may take more than 10 minutes for the tire pressure warning lamp to inform you of the malfunction by flashing for 60 seconds and then remaining lit. When the malfunction has been rectified, the tire pressure warning lamp goes out after driving for a few minutes.
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. 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.

After a teach-in period, the tire pressure monitor automatically recognizes new wheels or new sensors. As long as a clear allocation of the tire pressure values to the individual wheels is not possible, the Tire Pressure Monitor Active 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 wheel is mounted is not the same as the spare wheel/emergency spare wheel's current tire pressure.
TPMS 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 by a red rectangle.

Restarting the tire pressure monitor G Warning It is the driver's responsibility to set the tire inflation pressure to the recommended cold tire inflation pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle.
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 TPMS must be restarted when you set the tire pressure to a new value (as a result of changed handling or load characteristics, for example). The TPMS then monitors the new tire pressure values. i Canada only: in most cases, the tire pressure monitor recognizes the new reference values automatically. However, you can also define reference values manually as described here.
Restart the tire pressure monitor after you have set the tire pressure to the value recommended for the desired driving situation (Y page 352). Only correct tire pressures on cold tires. Comply with the recommended tire pressures on the Tire and Loading Information placard on the B-pillar on the driver's side Additional tire pressure values for driving at high speeds or with heavy loads can be found in the Tire Pressure table on the inside of the fuel filler flap.
