The standard-specification PRE-SAFE® can make use of the valuable seconds which precede an accident. The ESP® and BAS sensory system recognises critical driving situations, such as oversteer or understeer, abrupt steering movements, as well as panic or emergency braking. PRE-SAFE® electronically evaluates this information and, if a typical pre-crash situation is identified, can trigger anticipatory measures depending on the situation and vehicle equipment to protect the occupants. The front passenger seat can be adjusted into a more favourable position (provided it is fitted with the memory function), the optional sunroof and side windows can be closed and the seat belts pulled taut by an electric motor. When the danger has passed, the tension in the belts is released and all other components involved can return to their original positions.
