The PRE-SAFE® occupant protection system can recognise critical driving situations and, if necessary, pre-emptively activate reversible safety systems to help reduce the risk of injury to the vehicle occupants.
This is based on PRE-SAFE® continuously monitoring sensor data from systems such as ESP® and BAS and identifying driving situations such as oversteer/understeer and emergency stops.
If the typical characteristics of a critical driving situation are identified, safety systems can respond within a fraction of a second. The electronic belt tensioners are activated, the electrically adjustable front-passenger seat (only in conjunction with Memory Package) is moved to a more "favourable" crash position, and the side windows and (optional) panoramic sliding sunroof are closed automatically.
