PRE-SAFE® (preventative occupant protection)
WARNING
The PRE-SAFE® system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRESAFE ® system, the possibility of injury in the event of an accident cannot be ruled out. You should therefore always drive carefully and adapt your driving style to the prevailing road, weather and traffic conditions.
PRE-SAFE® takes preemptive measures to protect occupants in certain hazardous situations.
PRE-SAFE® intervenes:
- in emergency braking situations, e.g. if BAS
is activated or, in vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
- if the radar sensor system detects an
imminent danger of collision in certain
situations (on vehicles with DISTRONIC
PLUS)
- in critical driving situations, e.g. when
physical limits are exceed and the vehicle
understeers or oversteers severely
PRE-SAFE® takes the following measures depending on the hazardous situation detected:
- the front seat belts are pre-tensioned.
- it adjusts the front-passenger seat if it is in
an unfavorable position.
- the air pressure in the side bolsters of the
seat cushion and seat backrest of the front
active multicontour seats is increased.
- if the vehicle skids, the sliding sunroof/
panorama roof with power tilt/sliding
panel and the side windows are closed so
that only a small gap remains.
If the hazardous situation passes without resulting in an accident, PRE-SAFE® slackens the belt pretensioning. The air pressure in the side bolsters on the active multicontour seat
is reduced again. All settings made by PRESAFE ® can then be reversed.
If the seat belts are not released:
- Move the backrest or seat back slightly, but only when the vehicle is stationary.
The belt pretensioning is reduced and the locking mechanism is released.
WARNING
Make sure that nobody can become trapped
as you adjust the seat.
Make sure that there are no objects in the footwell or behind the seats when resetting the seats. There is a risk that the seats and/or the objects could be damaged.
More information about seat-belt adjustment, a convenience function integrated into PRE-SAFE®, can be found in the "Seat-belt adjustment" section
