GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed increase
Rthey may wear excessively and/or unevenly, which may greatlyimpair tire traction.
Rthe driving characteristics, as well as steering and braking, maybe greatly impaired
There is a risk of an accident.

Other driving systems and driving safety systems may also malfunction.
GWARNING
The brake system continues to function normally, but without the functions lis-ted above. The front and rear wheels could therefore lock if you perform a fullbrake application, for example.
The steerability and braking characteristics may be severely affected. The brak-ing distance in an emergency braking situation can increase.
If ESP®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XObserve the additional display messages in the multifunction display.
