Safety and Security Occupant safety Preventive occupant safety* (PRE-SAFE®) In such cases, the following systems are automatically activated: i The PRE-SAFE® system is activated in the previously described circumstances only at speeds exceeding 22 mph (35 km/h). When the driving dynamic situation has passed without an accident occurring, the pre-tensioning on the seat belts is deactivated. You can then adjust the seats and the tilt/sliding sunroof* to their previous position. If the seat belts do not release: Adjust the backrest or seat slightly to the rear until the seat belt tension is diminished. The locking mechanism releases. Warning! G The front seat belts are pre-tensioned electrically. Vehicles with front passenger seat memory function*: If the OCS senses that the front passenger seat is occupied and the seat is in an unfavorable position, it will be adjusted to a better position. Vehicles with tilt/sliding sunroof*: The tilt/sliding sunroof closes if the vehicle is in a severe skid or is spinning. The PRE-SAFE® system is intended to reduce the effects of an accident on properly seat-belted vehicle occupants. Despite having the PRE-SAFE® system in your vehicle, the possibility of injuries occurring as a result of an accident cannot be totally eliminated. Therefore you should always drive carefully and adjust your driving to the prevailing road, weather, and traffic conditions. Your vehicle automatically takes preventive measures to better protect the occupants in the following hazardous situations: You execute an emergency braking maneuver and the Brake Assist System ( page 99) is activated. The PRE-SAFE® system detects a critical driving dynamics situation. i If the closing procedure of the tilt/sliding sunroof* is blocked, the tilt/sliding sunroof* will stop and open slightly. 81
