Warning stages

Prewarning

This warning is issued, for example, when there is the impending danger of a collision or the distance to the vehicle ahead is too small.

Acute warning with braking function

Warning of the imminent danger of a collision when the vehicle approaches another object at a relatively high differential speed.

The acute warning prompts the driver to intervene and, if there is the danger of a collision, is accompanied by a braking intervention.

The braking intervention is executed with limited braking force and for a brief period only. The intervention cannot bring the vehicle to a complete standstill.

The braking intervention is executed only if DSC Dynamic Stability Control is switched on.

style Adapting your speed and driving style

The acute warning does not relieve the driver of the responsibility to adapt his or her driving speed and style to the traffic conditions.

The braking intervention can be interrupted by pressing on the accelerator or by actively moving the steering wheel.

When towing or tow-starting the vehicle, switch off the collision warning with braking function to prevent undesired interventions.

The braking function is deactivated if the DSC Dynamic Stability Control or DTC Dynamic Traction Control is deactivated.
