PRE-SAFE ® (anticipatory occupant
protection system)
Introduction
i AMG vehicles do not include the PRE-
SAFE ® system.
All vehicles (except AMG vehicles): the
PRE-SAFE ® system is only available in
vehicles with DISTRONIC PLUS.
PRE-SAFE ® takes preemptive measures to
protect occupants in certain hazardous
situations.
Important safety notes
!
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.
Despite your vehicle being equipped with the
PRE-SAFE ® system, the possibility of
personal injuries occurring as a result of an
accident 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
physical limits are exceeded and the
vehicle understeers or oversteers severely.
R on vehicles with DISTRONIC PLUS: if
BAS PLUS brakes hard or the radar sensor
system detects an imminent danger of
collision in certain situations.
PRE-SAFE ® takes the following measures
depending on the hazardous situation
detected:
R the seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
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 belts are not released:
X When the vehicle is stationary, move the
backrest or seat back slightly.
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"
