Front side impact air bags : and rear side
impact air bags ; deploy next to the outer bol-
ster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. However, it does
not protect the:
Head
R
Neck
R
Arms
R
If the restraint system control unit detects a side
impact, the side impact air bag is deployed on
the side on which the impact occurs.
The side impact 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 seat belt buckle tongue is engaged in the
R
belt buckle of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
of whether the front-passenger seat is occupied
or not.
Head air bags
Head bags : deploy in the area of the side win-
dows at the front.
When deployed, the head bag enhances the
level of protection for the head. However, it does
not protect the:
chest
R
arms
R
If the restraint system control unit detects a side
impact, the head 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
Occupant safety
seat belt, a head bag may be deployed in other
accident situations (

The head bag on the front-passenger side
deploys under the following conditions:

the seat belt buckle tongue is engaged in the
R

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 and front-passenger knee bag are
either enabled or deactivated.
The system does not deactivate:
the side impact air bag
R
the headbag
R
the Emergency Tensioning Devices
R
Requirements
To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in an almost upright position with their back
R
against the seat backrest
with their feet resting on the floor, if possible
R
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, 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 raised
R
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. a
page 56).
