PRE-SAFE (anticipatory occupant
protection system)
G
WARNING
Make sure that nobody can become trapped
as you adjust the seat.
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.
! 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.
®
PRE-SAFE takes preemptive measures to
protect occupants in certain hazardous
situations.
®
PRE-SAFE intervenes:
if BAS intervenes, e.g. in emergency
R
braking situations.
when BAS PLUS intervenes powerfully on
R
vehicles with DISTRONIC PLUS.
when 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 exceeded and the
vehicle understeers or oversteers severely.
®
PRE-SAFE takes the following measures
depending on the hazardous situation
detected:
the seat belts are pre-tensioned.

vehicles with a multicontour seat or active
R
multicontour seat: the air pressure in the
side bolsters of the seat cushion and
backrest is increased.
if the vehicle skids, the side windows are
R
closed almost completely.

resulting in an accident, PRE-SAFE

®
PRE-SAFE can then be reversed.

Important safety notes
G WARNING
Do not secure any objects (e.g. coat hangers)

protection they are designed to provide.
G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags are deployed, or they can
prevent this completely. The NECK-PRO head
restraints or side impact air bags can
therefore not provide the intended protection.
Do not use any seat or head restraint covers.
