Occupant safety

Thorax/pelvis air bags : deploy next to the
outer bolster of the seat backrest.
When deployed, the thorax/pelvis air bags
offer additional thorax and pelvis protec-
tion.
In the event of a side impact, the thorax/
pelvis air bag is deployed on the side on
which the impact occurs.
The thorax/pelvis air bag on the front-
passenger side deploys under the following
conditions:
the OCS system detects that the front-
R
passenger seat is occupied or
the belt tongue is engaged in the belt
R
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the thorax/pelvis air bag on the
front-passenger side deploys if an appro-
priate accident situation occurs. In this
case, deployment is independent of whether
the front-passenger seat is occupied or not.
Window curtain air bags
Window curtain air bags : are integrated
into the side of the roof frame above the
doors.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the 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 they can offer
additional 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)
categorizes the person in the front-
passenger seat. Depending on that result, the
front-passenger front air bag and front-
passenger knee bag are either enabled or
deactivated.
The system does not deactivate:
the thorax/pelvis air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
R
Prerequisites
To be classified correctly, the front
passenger must sit:
with the seat belt fastened correctly
R
in an almost upright position with their
R
back against the seat backrest
with their feet resting on the floor, if pos-
R
sible
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
transfers their weight by supporting them-
R
selves on a vehicle armrest
sits in such a way that their weight is
R
raised from the seat cushion
If you 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-
