on the side on which an impact occurs
R
at the start of an accident with a high rate
R
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
independently of the use of the seat belt
R
independently of the front airbags
R
independently of the belt tensioners

Windowbags
The windowbags enhance the level of protec-
tion for the head (but not chest or arms), of
the vehicle occupants on the side of the vehi-
cle on which the impact occurs.
The windowbags are integrated into the side
of the roof frame and deployed in the area
from the A-pillar to the C-pillar.

PRE-SAFE (preventative occupant
protection)
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
®
PRE-SAFE takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
®
PRE-SAFE intervenes:
in emergency braking situations, e.g. if BAS
R
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
if the radar sensor system detects an immi-
R
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
in critical driving situations, e.g. when phys-
R
ical limits are exceed and the vehicle under-
steers or oversteers severely
®
PRE-SAFE takes the following measures
depending on the hazardous situation detec-
ted:
the front seat belts are pre-tensioned.
R
it improves the seat position if, under acci-
R
dent conditions, the passenger seat is in an
unfavourable position.
if the vehicle skids, the panorama sliding
R
sunroof and the side windows are closed so
that only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
