Warning Caution
Tire MalfunctionAt least one tire is deflating.XCarefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers.XIf necessary, change the wheel ( Y page 405).0077
Check Tire PressureThe tire inflation pressure in at least one tire is significantly below
the reference value.XCarefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers.XCheck and adjust tire inflation pressure as required.XIf necessary, change the wheel ( Y page 405).GWarning!
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.
GWarning!
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.

GWarning!
Driving with the brake warning lamp illuminated can result in an accident. Have your brake system
checked immediately if the brake warning lamp stays on. Do not add brake fluid before checking
the brake system.
Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the
brake fluid catching fire. You can be seriously burned.
! If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum mark
or below, have the brake system checked for brake pad thickness and leaks.

GWarning!
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 engine oil temperature above 140†. Doing
so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.

GWarning!
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.
