Window curtain air bags
Window curtain air bags : are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
offers additional protection for the head.
However, it does not protect your chest or
arms.
In the event of a side impact, the window cur-
tain air bag is deployed on the side on which
the impact occurs.
If the system determines that window curtain
air bag deployment can offer additional pro-
tection to that provided by the seat belt, a
window curtain air bag may deploy in other
accident situations (
Y
page 59).
Cushion air bags
i Observe the "Important safety notes" sec-
tion (
Y
page 51).
The rear reclining seat is equipped with a
cushion air bag. If the seat backrest is
reclined, the cushion air bag can provide addi-
tional occupant protection in the event of
frontal collision situations. When triggered,
the cushion air bag deploys under the seat
cushion. This helps prevent the occupant
from slipping off the seat cushion.
G WARNING
If a child restraint system is installed and the
seat backrest is reclined too far backwards,
the cushion air bag may deploy by mistake in
the event of an accident. There is an increased
risk of injury.
When using a child restraint system, always
ensure that the seat is correctly adjusted and
that the backrest is almost vertical.
If you install a child restraint system on the
rear reclining seat, always observe:
R
the instructions and safety notes in "Chil-
dren in the vehicle" (
Y
page 63)
R the child restraint system manufacturer's
installation instructions.
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
disabled.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Prerequisites
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 possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, 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 position the child restraint system
