Coolant Too Hot:Stop Vehicle TurnEngine Off
An additional warning tone sounds. The coolant is too hot.
GWARNING
Never drive with an overheated engine. Driving when the engine is
overheated can cause fluids which may have leaked into the engine
compartment to catch fire.
In addition, steam from an overheated engine can cause serious
burns, which can occur just by opening the hood.
There is a risk of injury.
XStop the vehicle immediately, paying attention to road and traffic
conditions, and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XWait until the engine has cooled down.
XMake sure that the air supply to the radiator is not obstructed, by
frozen slush for example.
XDo not start the engine again until the display message goes out and
the coolant temperature is below the maximum value specified. The
engine could otherwise be damaged.
XMonitor the ?coolant temperature gage in the instrument clus-

pressure difference between the wheels is too great.
XCheck the tire pressure at the next opportunity (Ypage 284).
XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 287).
Check TiresAn additional warning tone sounds.
The tire pressure in one or more tires has dropped significantly. The
display shows the wheel position.
GWARNING
Underinflated tires pose the following risks:
RThe tires may burst, especially as the load and vehicle speed
increase.
RThe tires may wear excessively and/or unevenly, which may greatly
impair tire traction.
RThe handling as well as steering and braking characteristics may be
severely affected.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions while doing so.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XCheck the tires and, if necessary, change the wheel (Ypage 296).

XIf necessary, correct the tire pressure.
Warning Tire Mal‐functionThe tire pressure in one or more tires has dropped suddenly. The dis-
play shows the wheel position.
GWARNING
Driving with a flat tire poses a risk of the following hazards:
RA flat tire affects the ability to steer or brake the vehicle.
RYou could then lose control of the vehicle.
RContinued driving with a flat tire will cause excessive heat build-up
and possibly a fire.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions while doing so.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
