The Audi A3 is also setting new standards in the premium compact class when it comes to driver assistance systems. The most important of them is Audi adaptive cruise control, which maintains a desired distance to the car ahead by accelerating and braking – up to a vehicle speed of 150 km/h (93.21 mph). If the A3 driver orders the assistance package, which combines several systems, the control range is extended up to 200 km/h (124.27 mph).

In case of an impending collision, the ACC system warns the driver according to a progressively staged strategy. If necessary, it can initiate partial braking to reduce the car’s speed at impact.

If a collision does occur, an innovative system is activated in the A3. It prevents uncontrolled secondary car travel after the initial collision and simultaneously activates the interior lighting. If the Bluetooth car phone is on board, a call is also made to emergency services. Activated at speeds under 30 km/h (18.64 mph), the system applies full braking in an emergency situation.

Other systems complete the line-up. Audi side assist, which monitors traffic at the back of the car with radar, simplifies lane changes for the driver, while Audi active lane assist helps the driver to stay in the lane by making a slight steering correction if necessary. The system’s video camera is also used by the traffic sign detection system; it shows speed limits and other traffic signs on a monitor in conjunction with MMI navigation plus. The rest recommendation system detects when the driver is fatigued, and warns the driver accordingly.

Audi offers a number of systems for convenient parking, and park assist is at the top. It takes over steering duties for the driver in perpendicular and parallel parking. If necessary, it can make multiple forward and reverse maneuvers. Its 12 ultrasonic sensors detect obstacles around the car. New in the A3: park assist can be supplemented by a reversing camera.

Another high-end option is the Audi pre sense basic safety system. When it detects an unstable driving state via the sensors of the ESP stabilization system, it tensions the front seat belts with electric motors and closes the sunroof and side windows.
