R
independently of the front airbags
R
independently of the belt tensioners
R
if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
lateral direction and determines that side-
bag deployment can offer additional pro-
tection to that provided by the seat belt
Windowbags
The purpose of the windowbags is to enhance
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar).
Windowbags
:
are deployed:
R
at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
lateral direction
R
on the side on which an impact occurs
R
independently of the front airbags
R
regardless of whether the front-passenger
seat is occupied
R
if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
PRE-SAFE

system
PRE-SAFE
®
system takes pre-emptive meas-
ures to protect you in certain hazardous sit-
uations.
PRE-SAFE
®
intervenes in the event of:
R
emergency braking situations, e.g. if Brake
Assist BAS is activated or Brake Assist BAS
PLUS* intervenes powerfully
R
the radar sensor system detecting an
immediate danger of collision in certain sit-
uations (on vehicles with Distronic Plus*)
R
critical situations involving driving dynam-
ics, e.g. if the vehicle oversteers or under-
steers significantly due to physical limits
being exceeded
PRE-SAFE
®
may take the following measures
in these situations:
R
it tensions the front seat belts.
R
it adjusts the seats to a better position if
the front-passenger seat or the electrically-
adjustable outer seats in the rear compart-
ment* are in an unfavourable position
R
on vehicles with the multicontour seat* or
active multicontour seat*: it increases the
air pressure in the seat side cushions and
the backrest side cushions.
R
if the vehicle skids, it closes the sliding/
tilting sunroof* or panorama sliding sun-
roof* and the side windows so that only a
small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®
slackens
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE
®
. On vehicles
with a multicontour seat* or an active multi-
contour seat*, the air pressure in the side
bolsters is then reduced.
If the seat belts are not released:
X
Move the backrest back slightly until the
belt tension is reduced.
The locking mechanism releases.
