PRE-SAFE
®
(anticipatory occupant
protection)
Introduction
In certain hazardous situations, PRE-SAFE ®
takes pre-emptive measures to protect the
vehicle occupants.
Important safety notes
!
Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Although your vehicle is equipped with a PRE-
SAFE ® system, the possibility of injury in the
event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function
PRE-SAFE
®
intervenes:
R
in emergency braking situations, e.g. when
BAS is activated
R
in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R
vehicles with the Driving Assistance pack-
age: when a driver assistance system inter-
venes powerfully or the radar sensor sys-
tem detects an imminent danger of colli-
sion in certain situations
PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R
the front seat belts are pre-tensioned.
R
if the vehicle skids, the side windows are
closed so that only a small gap remains.
R
the front-passenger seat is adjusted if it is
in an unfavourable position.
R
vehicles with a multicontour seat: the air
pressure in the side bolsters of the back-
rest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®
slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats, the air pressure in the side
bolsters is reduced again. All settings made
by PRE-SAFE
®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X
Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE
®
convenience function. Infor-
mation about the convenience function can
be found under "Belt adjustment"
(

page 47).

®

pant protection PLUS)

emptive measures to protect the vehicle
