side deploys underthefollowing conditions:
R the OCS system detectsthat thefront

Introdu ction The
Occupant Classification System(OCS)cat-
egorizes theperson inthe front -passenger

The system doesnotdeactivate:
R the side impact airbag
R the window curtainairbag
R the Emergen cyTensionin gDevices
Requir ements To
be classified correctly,the front passenger
must sit:
R with theseat beltfasten edcorrec tly
R in an almost upright position withtheir back
against theseat backrest
R with their feetrestin gon the floor, ifpossi-
ble
If the front passenger doesnotobserve these
condit ions,OCSmayproduce afalse classifi-
cation, e.g.because thefront passenger:
R trans ferstheir weight bysupporting them-
selves onavehicle armrest
R sits insuch away that their weight israised
from theseat cushion
If it is absolutely necessarytoinstall achild
restr aintsystem onthe front -passenger seat,
be sure toobserve thecorrec tpositionin gof
