Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If it is absolutely necessary to install a childrestraint system on the front-passenger seat,be sure to observe the correct positioning ofthe child restraint system. Never place objectsunder or behind the child restraint system, e.g.a cushion. The entire base of the childrestraint system must always rest on the seatcushion of the front-passenger seat. The back-rest of the forward-facing child restraint sys-tem must lie as flat as possible against thebackrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.
