PRE-SAFE ® (preventative occupant
protection)
G 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 PRE-
SAFE
® 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:
R in emergency braking situations, e.g. if BAS
is activated or, in vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R if the radar sensor system detects an
imminent danger of collision in certain
situations (on vehicles with DISTRONIC
PLUS)
R 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:
R the front seat belts are pre-tensioned.
R on vehicles with memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
R 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 sliding sunroof, panorama roof with
power tilt/sliding panel or a side window is
obstructed during closing, the closing
procedure is stopped. The obstructed sliding
sunroof, panorama roof with power tilt/
sliding panel or side window opens again
slightly.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ® slackens
the belt pretensioning. All settings made by
PRE-SAFE ® can then be reversed.
If the seat belts are not released:
X
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.
G 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
