The optional extra PRE-SAFE® can capitalise on the valuable few seconds which precede an accident. The ESP® and BAS sensory system recognises critical driving situations, such as heavy 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, triggers 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 the side windows can be closed and the seat belts pulled taut.
