Occupant Classification System(OCS)cat-
egorizes theperson inthe fron t-passenger

must sit:
R with theseat beltfasten edcorr ectly
R in an almost upright position withtheir back
against theseat backr est
R with their feetrestin gon the floor, ifpossi-

If the fron tpassenger doesnotobserve these

cation ,e.g. because thefron tpassenger:
R tran sfers theirweight bysupportin gthem-
selves onavehicle armrest
R sits insuch away that their weight israised
from theseat cushion
If you installachild restraint system onthe
fron t-passenger seat,besure toobserve the
corr ectposition ingofthe child restraint sys-

The child restraintsystem mustnottouch the
