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.
®
PRE-SAFE takes preemptive measures to
protect occupants in certain hazardous
situations.
®
PRE-SAFE intervenes:
if BAS PLUS intervenes powerfully on
R
vehicles with DISTRONIC PLUS
if, on vehicles with DISTRONIC PLUS, the
R
radar sensor system detects an imminent
danger of collision in certain situations
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 front seat belts are pre-tensioned.
R

R

seat is adjusted if it is in an unfavorable
position.
if the vehicle skids, the sliding sunroof,
R

®
PRE-SAFE can then be reversed.
