Headbags
Headbags enhance the level of protection for
the head, but not the chest or arms, of the
vehicle occupants in the front of the vehicle
on the side on which the impact occurs.
Headbags
:deploy in the area of the side
windows at the front. They are deployed:
R at the start of an accident with a high rate
of lateral vehicle deceleratio noraccelera-
tion, e.g. in a side impact
R on the side on which an impact occurs
R on the driver's and the front passenger's
side if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the sea tbelt
R independently of the use of the seat belt
R regardless of whether the front-passenger
seat is occupied
R independently of the fron tairbags PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measure sto
protect occupants in certain hazardous sit-
uations. PRE-SAFE
®
intervenes:
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS.
R if, on vehicles with DISTRONIC PLUS, the
radar senso rsystem detects an imminent
danger of collision 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 seat belts are pre-tensioned.
R the front-passenger seat is adjusted if it is
in an unfavourable position.
R if the vehicle skids, the side windows 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. Al lsettings 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.
! 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.

ment ,aconvenience function integrated into

adjustment" section (Y page 46). NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection to the driver's and front passenger's

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the fron tpassenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrumen tcluster, seat
belt" (Y page 224).
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling the mclose against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts. 46
