H Tire Pressure

Check Tires

The tire pressure in one or more tires is already below the minimum value.

Possible solution X Check and correct tire inflation pressure as

required (Y page 255).

X Carefully bring the vehicle to a halt, avoiding

abrupt steering and braking maneuvers.

X If necessary, change the wheel (Y page 355). X Carefully bring the vehicle to a halt, avoiding

abrupt steering and braking maneuvers.

X Check and adjust tire pressure as required. X If necessary, change the wheel (Y page 355).

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire. 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.

Ì The red coolant

temperature warning lamp comes on when the engine is running and an acoustic warning sounds.

Possible cause/consequence There is insufficient coolant in the reservoir. If this warning lamp comes on frequently, there is a leak in the cooling system. If the coolant level is correct, the electric radiator fan may be broken. The coolant temperature has exceeded 248‡ (120†).

Suggested solutions X Immediately add coolant to prevent engine from overheating

(Y page 245).

X Have the cooling system checked. X If the coolant temperature is below 248‡ (120†), you can

continue driving to the nearest authorized Mercedes-Benz Center. X Avoid high engine loads (e.g. driving uphill) and stop-and-go driving.

X Stop in a safe location as soon as possible and allow the engine

and coolant to cool down.

G Warning! Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned.

Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

H USA only:

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

Possible cause/consequence The TPMS (USA only) or Advanced TPMS (Canada only) detects a loss of pressure in at least one tire.

There is a malfunction in the TPMS.

Suggested solutions 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 295).

If the tire inflation pressure in the respective tire(s) has (have) been corrected, the combination low tire pressure/TPMS malfunction telltale goes out after a few minutes of driving.

X Read and observe messages in the multifunction display

(Y page 295).

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 vehicle 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

340

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 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

TPMS malfunctions may occur for a variety of reasons, including the installation of 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.

Resetting activated head restraints Resetting activated head restraints

If the active head restraints have been triggered in a rear-end collision, the active head restraints must be reset. You can tell that the active head restraints have been triggered when they have been moved forward and cannot be adjusted. G Warning! For safety reasons, have the active head restraints checked at an authorized Mercedes-Benz Center after a rear-end collision. G Warning! When pushing back the head restraint cushion, make sure your fingers do not become caught between the head restraint cushion and the cover. Failing to do so may lead to injury.
