PRE-SAFE
®
(anticipatory occupant
protection system)
Introduction
PRE-SAFE ® takes preemptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes
!
Make sure that there are no objects in the
footwell or behind the seats. There is a dan-
ger that the seats and/or objects could be
damaged when PRE-SAFE
®
is activated.
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:
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 and
the panorama roof with power tilt/sliding
panel are closed.
R
vehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®
slackens
the belt pre-tensioning. 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.
The 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. You
will find information on the convenience func-
tion under "Belt adjustment" (
Y
page 47).

pant protection system PLUS)
