The concept
The system issues a two-phase warning of a danger of collision at speeds above approx. 10 mph/15 km/h.
The collision warning is available even if cruise control has been deactivated.

It responds to moving objects that are within the detection range of the radar system.
When the vehicle is intentionally brought into contact with an object, the collision warning is delayed to avoid false warnings.
