The PRE-SAFE® preventive occupant protection system can identify potentially critical driving situations at an early stage and initiate protective measures for the occupants. The measures include reversible tightening of the driver's and front passenger's seat belts, closing open windows and roof systems and – in conjunction with electric seat adjustment – positioning the front passenger seat in a better position to cope with an accident.
The intelligent accident early-warning system in the PRE-SAFE® system works through the sensors present in the vehicle, e.g. the Electronic Stability Program ESP® or BAS PRO Brake Assist. The protective mechanisms of the PRE-SAFE® system are triggered by panic braking, in which the driver needs to brake harder than road conditions would normally allow, and by acute steering movements at high speeds.
The PRE-SAFE® system is optionally available for the V-Class and standard for the V-Class AVANTGARDE.In conjunction with the optional electric seat adjustment function, the scope of the system widens to include the positioning of the front passenger seat in a better position to cope with an accident.
