During severe operation conditions and stop-and-go city
traffic, the coolant temperature may rise close to 248‡

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 coolant temperature above 248‡ (120†).
Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited
Warranty.

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 508).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.

Lamps in instrument cluster
Notes
If any of the following lamps in the instrument
cluster fails to come on during the bulb self-
check when switching on the ignition, have
the respective bulb checked and replaced if
necessary.
When you switch on the ignition, all lamps in
the instrument cluster come on. The high-
beam headlamp indicator lamp and turn
signal indicator lamps will only come on if
activated. If a lamp in the instrument cluster
fails to come on when the ignition is switched
on, have it checked and replaced if necessary.GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not receive all
necessary safety information and warning for
the operation of your vehicle.
