Driver assistance systems

The driver assistance systems embody the TT philosophy: they relieve the driver of work, so that he or she can fully concentrate on the road. The standard scope includes the multicollision brake assist  and the attention assist.

The optional Audi side assist helps the driver change lanes at vehicle speeds from 30 km/h (18.6 mph). Once the system classifies another vehicle in the blind spot or approaching rapidly as critical for a lane change, it warns the driver via a bright LED on the exterior mirror. If the driver still activates the turn signal, the indicator flashes several times.

The Audi active lane assist (standard or optional depending on the engine version) becomes active from about 65 km/h (40.4 mph). A camera at the interior mirror recognizes the lane markings on the road. If the TT approaches a lane marking without signaling, the system uses a gentle nudge of the electromechanical steering wheel to prompt the driver to steer back into the lane.

Another optional feature, traffic sign recognition, also uses the data from the video camera. It compares data with the navigation system to indicate speed limits, auxiliary signs and no-passing zones.

Three systems are available for convenient and safe parking: the top-of-the-line version, namely the park assist, can steer the TT backwards into parking spaces that are either parallel or perpendicular to the road. The display of the surroundings warns the driver about obstacles on the sides, the reversing camera shows in the Audi virtual cockpit the area behind the car to facilitate maneuvering.
