ClassificationSystem
(OCS)
Introduction The
Occupant Classification System(OCS)cat-
egorizes theperson inthe front -passenger
seat. Depending onthat result, thefront -
passenger frontairbag and front -passenger
knee bagareeither enabled ordeactivated.
The system doesnotdeactivate:
R the side impact airbag
R the headba g
R the Emergenc yTensioning Devices
Requirements To
be classified correctly,the front passenger
must sit:
R with theseat beltfastened correctly
R in an almost upright position withtheir back
agai nstthe seat backrest
R with their feetresting onthe floor, ifpossi-
ble
If the front passenger doesnotobserve these
conditions, OCSmayproduce afalse classifi-
cation, e.g.because thefront passenger:
R transfers theirweight bysupporting them-
selves onavehicle armrest
R sits insuch away that their weight israised
from theseat cushion
If you install achild restraint systemonthe
front -passenger seat,besure toobserve the
correct positioning ofthe child restraint sys-
tem. Never placeobjects underorbehind the child
restraint system,e.g.acushion. Fully
retract theseat cushion length.Theentire
base ofthe child restraint systemmustalways
rest onthe seat cushion ofthe front -
passenger seat.Thebackrest ofthe forward-
facing childrestraint systemmustlieasflat as
possible againstthe backrest ofthe front -
passenger seat.
The child restraint systemmustnottouch the
roof orbe subjected toaload bythe head
restraint. Adjusttheangle ofthe seat backrest
and thehead restraint positionaccordingly.
Only thencanOCS beguara nteed tofunction
correct ly.Always observe thechild restraint
