At least 4 years old
• Car seat must be forward-facing in the
vehicle back seat.
• Vehicle seat belts MUST lay flat against
child and MUST NOT be twisted.
• Make sure vehicle seat’s lap belt is
adjusted snugly, lays low on the child’s
hip, and is routed behind the armrest in the
booster’s belt path marked with a green
label.
• Make sure vehicle seat’s shoulder belt is
centered between the child’s neck and edge
of shoulder.
• Never use a vehicle lap only seat belt across
front of child.
• DO NOT position vehicle shoulder belt under
the child’s arm or back.
• DO NOT allow child to slouch or slide down
in the booster seat.
• DO NOT position vehicle seat belt over top of
armrests.
• When forward-facing, children should use
the built-in harness system for as long as
possible until they reach the maximum
forward-facing weight or height for their car
seat. A booster is no longer needed once the
vehicle seat belt fits properly, typically when
they reach 4 feet 9 inches (145 cm) tall and
are between ages 8-12. Be sure to check
your local and state laws, as well as AAP
and NHTSA recommendations, for car seat
usage.
