a lap/shoulder belt fits properly without a
booster.
Install child seat according to manufacturer’s
instructions.
The child seat must be firmly attached to both
anchors.
An incorrectly mounted child seat may come
loose during an accident which could result in
serious injury or death to the child.

Warning!
According to accident statistics, children are
safer when properly restrained in the rear seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
