Windowbags
:are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R regardless of whether the front-passenger
seat is occupied
R independently of seat belt use
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 in emergency braking situations, e.g. if BAS
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R if the radar senso rsystem detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical driving situations, e.g. when phys-
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:
R the fron tseat belts are pre-tensioned.
R vehicles with the memory function :it
adjusts the front-passenger seat if it is in
an unfavourable position.
R if the vehicle skids, the panorama sliding
sunroo fand the side windows are closed so
tha tonly a small gap remains.
If the hazardous situatio npasses without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning .All settings 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 mechanis mis released. G
WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! 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

The NECK-PRO head restraints increase pro-
tection to the driver's and front passenger's
head and neck.T o this end, the NECK-PRO
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity. This provides better head
support. 50

X Pull the seat belt smoothly through belt
sash guide :.
X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of

R
you engage the belt tongue in the belt
buckle and you then turn the key to position

not hold on to the seat belt tightly while it is
adjusting. On vehicles with a luxury multi-
function steering wheel (12 buttons), you can
switch the seat-belt adjustment on and off
using the on-board computer (Y page 228).
The seat-belt adjustment is an integral part of
the PRE-SAFE ®

can be found
in the "PRE-SAFE ®
(preventative occupant
protection)" section (Y page 50).
Releasing seat belts X
Press release button ?(Ypage 53) and
guide belt tongue ;back towards belt
sash guide :.
i If you have guided the seat belt back, it is
turned 180 °. This is necessary in order to
guarantee that the seat belt is not twisted
and that it is routed correctly when the belt
is fastened.
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.
