H USA only:


Combination low tire pressure telltale/TPMS malfunction telltale for the TPMS flashes 60 seconds and then stays illuminated.


Possible cause/consequence


Suggested solutions


The TPMS detects a loss of pressure in at least one tire.


X Carefully bring the vehicle to a halt, avoiding abrupt steering and


braking maneuvers. Observe the traffic situation around you.


X Read and observe messages in the multifunction display


(Y page 305).

There is a malfunction in the TPMS.


X Read and observe messages in the multifunction display


(Y page 305).


X Have the TPMS checked by an authorized Mercedes-Benz Center. After the malfunction has been remedied, the combination low tire pressure/TPMS malfunction telltale goes out after a few minutes of driving.


G Warning! Each tire, including the spare (if provided), should be checked every other week 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, if available,


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, if available, 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

Practical hints


What to do if … 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. Lamp in center console


Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the 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 1 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 illuminated, 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.

Replacing wiper blades Safety notes G Warning! For safety reasons, switch off wipers and remove SmartKey from starter switch (vehicles with KEYLESS-GO: Make sure the vehicle’s on-board electronics have status 0) before replacing a wiper blade. Otherwise, the wiper motor could suddenly turn on and cause injury. G Warning! Wiper blades are components that are subject to wear and tear. Replace the wiper blades twice a year, preferably in the spring and fall. Otherwise the windows will not be properly wiped. As a result, you may not be able to observe surrounding traffic conditions and could cause an accident.


! Never open the hood when a front wiper


arm is folded forward. Hold on to the wiper when folding a wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield or the rear window.


Do not allow a wiper arm to contact the windshield glass or the rear window without a wiper blade inserted. Mercedes-Benz recommends that you have this work carried out at an authorized Mercedes-Benz Center.


X Remove the SmartKey from the starter


switch.


Vehicles with KEYLESS-GO: X Make sure the vehicle’s on-board


electronics have status 0 (Y page 96).

Flat tire Safety notes Your vehicle may be equipped with an MOExtended system or a spare wheel with collapsible tire. Vehicles with an MOExtended system do not have a spare wheel. For information on your vehicle’s equipment, see “Rims and tires” (Y page 394). G Warning! The dimensions of the spare wheel are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a spare wheel mounted. Adapt your driving style accordingly. The spare wheel is for temporary use only. When driving with spare wheel mounted, ensure proper tire inflation pressure and do not exceed a vehicle speed of 50 mph (80 km/h). Contact the nearest authorized Mercedes- Benz Center as soon as possible to have the spare wheel replaced with a regular road wheel. Never operate the vehicle with more than one spare wheel mounted.


Practical hints


Flat tire


Do not switch off the ESP® when a spare wheel is mounted. G Warning! Vehicles with AIRMATIC: Do not open or close any doors or the tailgate while mounting a spare wheel. The vehicle could rise or lower to a previously selected level. You or others could be injured as a result.


Preparing the vehicle X Vehicles with AIRMATIC:


Make sure the vehicle level is set to highway level (Y page 166).


X Park the vehicle in a safe distance from


moving traffic on a hard, flat surface when possible.


X Turn on the hazard warning flasher. X Turn the steering wheel so that the front wheels are in a straight-ahead position.


X Engage the parking brake. X Shift the automatic transmission into park

Lifting the vehicle G Warning! When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle. The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. Make sure the jack arm is fully seated in the jack take-up bracket. The jack must always be vertical when in use, especially on inclines or declines. The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for performing maintenance work under the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Always firmly set the parking brake and block the wheels with wheel chocks or other sizeable objects before raising the


vehicle with the jack. Do not disengage the parking brake while the vehicle is raised. Make sure that the ground on which the vehicle is standing and where you place the jack is solid, level and not slippery. If necessary, use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-slip underlay, for example a rubber mat. Do not use wooden blocks or similar objects to support the jack. Otherwise the jack may not be able to achieve its load- bearing capacity if it is not at its full height. Never start the engine when the vehicle is raised. Also observe the notes on the jack.


X Prevent the vehicle from rolling away by


blocking wheels with wheel chocks or other sizeable objects. One wheel chock is included with the vehicle tool kit (Y page 300). For information on setting up the collapsible wheel chock, see (Y page 302). G Warning! Only jack up the vehicle on level ground or on slight inclines/declines. Otherwise, the
