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:
in emergency braking situations, e.g. if BAS
R
is activated or, in vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
if the radar sensor system detects an
R
imminent danger of collision in certain
situations (on vehicles with DISTRONIC
PLUS)
in critical driving situations, e.g. when
R
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.
R
it adjusts the seats if the front-passenger
R
seat or the electrically adjustable outer
seats in the rear are in unfavorable
positions.
vehicles with a multicontour seat or an
R
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
vehicles with multicontour seats in the
R
rear: the air pressure in the backrest side
bolsters of the outer seats in the rear is
increased.
if the vehicle skids, the sliding sunroof/
R
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
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All
settings made by PRE-SAFE
reversed.
If the seat belts are not released:
X
Move the backrest 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.
