Extra protection in the event of an impending rear-end collision.

If a rear-end collision threatens, this enhancement to the PRE-SAFE® system is able to initiate preventive occupant protection measures.

Radar sensors in the rear bumper monitor the area behind the vehicle. When a danger of a rear-end collision is detected, PRE-SAFE® PLUS flashes the rear hazard warning lights at a conspicuously high frequency to warn the driver following behind. If the vehicle is at a standstill, the brake pressure can be actively increased. This brake locking function reduces the loads acting on the occupants during an impact, and then prevents the vehicle from rolling forward e.g. at a junction or pedestrian crossing. This means that in addition to protecting the vehicle occupants the risk of secondary accidents is also reduced. The functions further include reversible belt tensioning for driver and front passenger. In addition, their seat belt buckles can be tensioned downwards from a neutral position. The resultant tension in the belt system secures the occupants even more effectively in place.

Only available as part of the Driving Assistance Plus Package.
