OCCUPANT RESTRAINT SYSTEMS
G16050
CAUTION
D Never install a rear−facing child restraint system on
the front passenger seat. In the event of an accident,
the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child
if the rear−facing child restraint system is installed
on the front passenger seat.

"Move seat fully back
D A forward−facing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat as
far back as possible, because the front passenger
airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously
injured.
D Do not allow the child to lean his/her head or any part
of his/her body against the door or the area of the
seat, front or rear pillar or roof side rail from which the
front (or rear) side airbags or curtain shield airbags
deploy even if the child is seated in a child restraint
system. It is dangerous if the front (and rear) side
airbags and curtain shield airbags inflate, and the
impact could cause death or serious injury to the
child.
