10.3.2. Acute Warning with Brake Application Function

The acute warning comes if there is an imminent danger of collision, whenever the vehicle approaches another object with a relatively high speed difference.

If there is an acute warning, the driver is shown a red flashing vehicle in the instrument panel and, if present, in the Head-Up Display. Additionally, an audible warning signal sounds. The driver is prompted to brake and, where appropriate, to take evasive action.

The acute warning prompts you to intervene and, if there is a danger of collision, usually assists with brake intervention.

The brake intervention has a maximum brake force of 3 m/s² and is only for a limited time. Brake intervention occurs only in the case of detected objects that are moving or have stopped. In the case of objects that were already still when they entered the detection range of the sensor, there is no braking.

The system cannot brake the vehicle to a standstill.

Brake intervention occurs only if the Dynamic Stability Control is switched on.

NOTE: The acute warning does not relieve the driver of the responsibility for adjusting the speed and driving style to the traffic conditions.

The brake intervention can be cancelled by depressing the accelerator pedal or by an active steering wheel movement.

When towing or being towed, switch off the collision warning with braking function in order to avoid malfunctions.

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

NOTE: Due to system limitations, it can happen that warnings are issued without cause, too late or not at all. For safety reasons, you must be attentive in order to be able to take action at any time.
