intervenes:
R when BAS activates, e.g. in emergency
braking situations
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detectsani mminent
dange rofcollision in certain situations
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R vehicles with a multicontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and back-
rest is increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings made by PRE-SAFE ®
can then be
reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released. 50
