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 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 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
package: when BAS PLUS intervenes pow-
erfully or the radar sensor system detects
an imminent danger of collision in certain
situations.
If you are driving faster than approximately
20 mph (30 km/h) PRE-SAFE ® may take the
following measures in these situations:
R the front seat belts are pre-tensioned.
R
vehicles with the 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 side windows are
closed so that only a small gap remains.
The panorama roof with power tilt/sliding
panel is completely closed.
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. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
(
