Windowbags
Windowbags : are integrated in the side of the
roof frame and deploy in the area from the A-
pillar to the C-pillar.
When deployed, the windowbag enhances the
level of protection for the head. However, it does
not protect the chest or arms.
When the restraint system control unit detects a
side impact, the windowbag is deployed on the
side on which the impact occurs.
If the system determines that it can offer addi-
tional protection to that provided by the seat
belt, a windowbag may be deployed in other
accident situations (

Automatic front-passenger front air-
bag deactivation
Introduction
In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat-
egorises the person in the front-passenger seat.
Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:

the windowbag

Make sure that your vehicle is equipped with the
automatic front-passenger front airbag deacti-
vation system ( page 60). If this is not the

case, always install a child restraint system on a
suitable rear seat ( page 61).

If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. Fully retract the seat cushion length.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of a forward-
facing child restraint system must, as far as
possible, rest flat against the backrest of the
front-passenger seat. The child restraint system
must not touch the roof or be put under strain by
the head restraint. Adjust the angle of the seat
backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system ( page 61) in addition to the
Y
child restraint system manufacturer's installa-
tion instructions.
