XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 289).
CheckTirePressureSoonAn additional warning tone sounds.
The tire pressure in one or more tires has dropped significantly.
GWARNING
Tire pressure that are too low pose the following hazards:
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 135).
XCheck the tires and, if necessary, change the wheel (Ypage 298).
XCheck the tire pressure (Ypage 286).
XIf necessary, correct the tire pressure.
Caution! Tire Mal‐func.
The tire pressure in one or more tires has dropped suddenly.
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
