Audi Q2 side assist
The lane change assistant Audi side assist is active at speeds of 15 km/h (9.3 mph) and above. It uses two rear-mounted radar sensors with a scanning range of roughly 70 meters (229.7 ft). If a vehicle is located in the blind spot or approaches rapidly, a warning LED in the housing of the respective exterior mirror lights up. If the driver still operates the turn signal, the LED flashes brightly several times in succession.
