(C) Booster seat installation
A booster seat is used in forward facing position only.
COMFORT ADJUSTMENT
"Move seat fully back
CAUTION
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 force of the
deploying front passenger airbag could cause death
or serious injury to the child.
D On vehicles with side airbags and curtain shield
airbags, do not allow the child to lean over the front
door or around the front door even if the child is
seated in a child restraint system. It is dangerous if
the side airbag and curtain shield airbag inflate,
because the impact could cause death or serious
injury to the child.
