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

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.

Warning

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.

Symbol for collision warning on the windscreen

In cars equipped with a head up display*, the warning is shown on the windscreen by a flashing symbol.

Note

Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windscreen difficult to recognise.
