Unsuitable seatcovers canobstruct orpre-

cann otprotec tvehicle occupant sas they are
designed todo. Inaddition, theoperation of
the occupant classification system(OCS)

When deployed, theside impact airbag offers

R the seat beltbuckle tongue isengaged inthe
belt buckle ofthe front -passenger seat If
the belt tongue isengaged inthe belt buckle,
the side impact airbag onthe front -passenger
