Audi lane assist helps the driver to stay in lane alerting them if they move off.
Audi lane assist detects lane markings by means of a camera on the front of the vehicle. The system is operational as soon as the camera detects road markings on both sides of the vehicle's lane.
If the vehicle starts to drift towards one of the detected lane markings, vibrations in the steering wheel warn the driver the vehicle is moving out of its lane. No warning is given if the driver is indicating with the turn signal.
The system is designed for driving on motorways and main roads, and works at speeds above approx. 60 km/h. Audi lane assist does not actively intervene in the driving situation.
