Audi pre sense basic initiates preventive measures, within system limits, to protect occupants by connecting and comparing different vehicle systems. In the event of an unstable driving state, the front seat belts are tightened electrically. Depending on the situation, the windows and – if present – the sliding sunroof close. The hazard warning lights illuminate to warn following vehicles. Coupled with Audi Side Assist, the system warns, within system limits, of critical situations involving vehicles approaching from behind.
The systems only work within system limits and are only able to assist the driver. The driver remains responsible for the vehicle on the road and for paying adequate attention.
