The lane change assistant Audi side assist aids the driver when changing lane. With its radar sensors in the rear bumper, the system monitors traffic in the driver’s blind spot. When a vehicle approaches from behind, the LED warning signal lights up.
The area beside and behind the vehicle is monitored by radar sensors at speeds above 30 km/h. When there is a vehicle in the blind spot or a vehicle is approaching rapidly from behind, the LED signal in the respective exterior mirror is continuously illuminated as a warning to the driver. If the turn signal is operated in this situation, the lights in the exterior mirror flash to alert the driver to the danger of a collision. Audi side assist does not actively intervene in the controlling of the vehicle and the driver may deactivate it at any time by pressing a button on the driver door.
