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 side impact air bag

the window curtain air bag

the Emergency Tensioning Devices

Prerequisites

To be classified correctly, the front passenger

must sit:

with the seat belt fastened correctly

in an almost upright position with their

back against the seat backrest

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:

transfers their weight by supporting them-

selves on a vehicle armrest

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 back-

rest and the head restraint position accord-

ingly.
Only then can OCS be guaranteed to function

correctly. Always observe the child restraint

system manufacturer's installation instruc-

tions.
