Window curtain air bags
Example: window curtain air bag above front door
Example: window curtain air bag for all rows of
seats
Window curtain air bags
:
or
;
are integrated
into the side of the roof frame. Window curtain
air bags for all rows of seats
;
deploy in the
area extending from the front door (A-pillar) to
the rear side window (D-pillar).
When deployed, the window curtain air bag
offers additional head protection. However, it
does not protect the chest or arms.
In the event of a side impact, the window curtain
air bag 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 window curtain air bag may be deployed
in other accident situations (

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not disable:
R
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
Conditions
To be classified correctly, the front passenger
must sit:
R
with the seat belt fastened correctly
R
in an almost upright position with their back
against the seat backrest
R
with their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
R
transfers their weight by supporting them-
selves on a vehicle armrest
R
sits in such a way that their weight is raised
from the seat cushion
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.
cushions. The entire base of the child restraint
system must always rest on the seat cushion of
the front-passenger seat. The backrest of the
forward-facing child restraint system must lie as
flat as possible against the backrest of the front-
passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation instructions.
