The concept

Two radar sensors below the rear bumper monitor the area behind and next to the vehicle at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehicles in the blind spot, arrow 1, or approaching from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights up dimly.
Before you change lanes after setting the turn signal, the system issues a warning in the situations described above.
The lamp in the housing of the exterior mirror flashes and the steering wheel vibrates.
