Audi pre-sense basic and rear
The system uses additional radar sensors to detect possible rear-end collisions. Hazard warning lights are activated; front seat belts are tensioned; windows are closed and, if fitted, the glass sunroof is also closed.

Lane change (side) assist
The system assists the driver when changing lanes using two radar sensors to identify the distance and speed in which other identified vehicles are approaching the vehicle from behind. When the lane change warning identifies that the speed difference and distance is critical for a lane change manoeuvre, the driver is alerted by a display in the relevant exterior mirror.

Exit warning
When the vehicle is stationary, the exit warning can detect vehicles and cyclists approaching from the rear and, if necessary, warn occupants before opening their door through a flashing warning LED in the appropriate door.

Cross-traffic assist rear
The system helps the driver when reversing out of bay parking spaces by notifying them of detected approaching vehicles in the MMI display. In recognised critical situations, the system can warn the driver using a warning tone and, if necessary, give a brief jolt of the brakes.
