Audi Side Assist Aids the driver when changing lane. Audi Side Assist monitors the area behind your car using radar sensors located discreetly in the rear bumper. It then informs the driver with a visual warning signal in the door mirror if there is a vehicle in their blind spot or approaching quickly from behind.

In conjunction with Audi Parking System Plus or Park Assist Cross Traffic Assist rear is also included - This Warns the driver of traffic crossing behind their own vehicle when starting to reverse without having a clear view of the situation (e.g. parking space with restricted view or narrow driveway). The system alerts the driver first visually and then acoustically via the MMI, and can apply a brake jolt if a potential collision is detected
