Warning from cruise control functions in the event of a risk of collision

The driver support systems of adaptive cruise control* and Pilot Assist* can warn the driver if the distance to the vehicle ahead suddenly becomes too short.

Adaptive cruise control and Pilot Assist use approx. 40% of the capacity of the foot brake. If the car needs to be braked more heavily than the driver support is capable of and the driver does not brake, the warning lamp and acoustic warning are activated to alert the driver that immediate intervention is required.


The driver support systems only warn of vehicles which their radar unit has detected – hence a warning may not be given, or it may be given with a certain delay. Never wait for a warning. Apply the brakes when the situation requires.
