Possible causes/consequences and M Solutions At least one tire is deflating. X Carefully bring the vehicle to a halt, avoiding abrupt

X If necessary, change the wheel (Y page 323).
The tire inflation pressure in at least one tire is significantly below the reference value. X Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers.
X Check and adjust tire inflation pressure as required. X If necessary, change the wheel (Y page 323).
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.

Possible causes/consequences and M Solutions 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. X Immediately add coolant to prevent engine from overheating
(Y page 226).
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.
The coolant temperature has exceeded 248‡ (120†). X Stop in a safe location as soon as possible and allow the engine
and coolant to cool down.
Problem ? The red coolant
temperature warning lamp comes on when the engine is running.
? The red coolant
temperature warning lamp comes on when the engine is running and an acoustic warning sounds.
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.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with
the coolant temperature above 248‡ (120†). Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.

Version: 2.11.8.1Possible causes/consequences and M Solutions The Advanced 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.

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 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 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.

G Warning! Batteries contain poisonous and corrosive substances. Therefore, keep the batteries out of reach of children. If a battery is swallowed, seek medical help immediately. G Warning! SmartKey batteries contain perchlorate material, which may require special handling and regard for the environment. Check with your local government’s disposal guidelines. California residents, see www.dtsc.ca.gov/ HazardousWaste/Perchlorate/ index.cfm. Batteries contain materials that can harm the environment if disposed of improperly. Recycling of batteries is the preferred method of disposal. Many states (USA only) or provinces (Canada only) require sellers of batteries to accept old batteries for recycling. When inserting the batteries, make sure they are clean and free of lint. When replacing batteries, always replace both batteries. i The required replacement batteries are
available at any authorized Mercedes-Benz Center.
Replacement batteries: Lithium, type CR 2025 or equivalent. X Remove the mechanical key from the
SmartKey (Y page 315).
