Window curtain air bags on the driver's and

front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the
seat belt
i Not all air bags are deployed in an acci-
dent. The different air bag systems work
independently of each other.
How the air bag system works is deter-
mined by the severity of the accident detec-
ted, especially the vehicle deceleration or
acceleration and the apparent type of acci-
dent:
frontal collision

PRE-SAFE (anticipatory occupant
protection system)
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.
Despite your vehicle being equipped with the
®
PRE-SAFE system, the possibility of per-
sonal injuries occurring as a result of an acci-
dent cannot be eliminated. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-
fully.
Function

PRE-SAFE intervenes:
in emergency braking situations, e.g. when
R
BAS is activated
in critical driving situations, e.g. when phys-
R
ical limits are exceeded and the vehicle
understeers or oversteers severely
vehicles with the Driving Assistance pack-
R
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:
the front seat belts are pre-tensioned.
R
if the vehicle skids, the panorama roof with
R
power tilt/sliding panel and the side win-
dows are closed so that only a small gap
remains.
the front-passenger seat is adjusted if it is
R
in an unfavorable position.
for vehicles with electrically adjustable rear
R
seats: the outer rear seats are adjusted if
they are in an unfavorable position.
®
vehicles with a multicontour seat: the air
R
pressure in the side bolsters of the seat
backrest is increased.
vehicles with seat belt extenders: the seat
R
belts of the outer rear seats are pre-ten-
sioned.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
