BAS (Brake Assist), Active Brake Assist, ESP®(Electronic Stability Program), theHOLD function and hill start assist, for example, are also deactivated.
ATTENTION ASSIST is deactivated.
GWARNING
The brake system continues to function normally, but without the functions lis-ted above. The wheels could therefore lock if you brake hard, 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.
