Exit warning improves safety in city traffic. If the car has come to a stop and other vehicles or bicyclists classified as critical are approaching from the rear, the system warns passengers not to open the doors.
The system does this using LED lights in the door panels. In a situation assessed to be hazardous, the LEDs flicker and light red. The LEDs of Audi side assist are also lit in the relevant exterior side mirror. The exit warning remains active for approximately three minutes after the ignition is turned off.
This system is based on the radar sensors of Audi side assist, which monitor the zones behind the vehicle and to the sides at the rear. Depending on the model the exit warning is extended by an additional feature: If the system is active, opening of the electronic door locks is delayed roughly one second.
