The concept
If the vehicle does not include Active Cruise Control with Stop & Go, the collision warning is controlled via the camera in the base of the interior rearview mirror.
The system issues a two-phase warning of a danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings may vary depending on the current driving situation.

In the process, vehicles in a similar direction of movement are observed if they are located within the detection range of the system.
When the vehicle is intentionally brought into contact with a vehicle, the collision warning is delayed to avoid false warnings.
