When changing lane, for example, it can warn the driver and apply selective braking to individual wheels to avert a potential collision.

The Active Blind Spot Assist radar sensors monitor the hard-to-see sector at the sides and behind the vehicle. If a vehicle is detected in the blind spot area, a red triangle appears in the relevant exterior mirror. If the driver fails to notice the warning and indicates to signal a lane change, the warning light starts to flash and an audible warning is sounded. If the driver attempts to change lanes despite the warnings, the system can warn the driver again by means of tangible course-correcting braking interventions. If the driver still fails to react, the system can actively help to manoeuvre the vehicle out of the danger zone.

Active Blind Spot Assist is operational at speeds over 30 km/h. Course-correcting braking interventions can be made in the speed range from 30 to 200 km/h.
