Collision risk warning from speed-controlling functions
The driver support systems Adaptive Cruise Control* and Pilot Assist* can help alert the driver if the distance to the vehicle ahead suddenly decreases to an unsafe distance.

Camera and radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity. If a situation requires more braking force than driver support can provide, and if the driver does not apply the brakes, a warning light and audible warning signal will be activated to alert the driver that immediate action is required.
Warning
The driver support system only issues a warning for vehicles detected by its radar unit – thus, a warning may come after a delay or not at all. Never wait for a warning. Apply the brakes when necessary.
