Seating and Safety Restraints
Installing child safety seats with combination lap and shoulder
belts
If needed, when installing some high back child restraints, the head
restraints of the second row seating positions can be removed. Insert a
thin pointed object, such as a paper clip or pushpin, into the hole of
each head restraint guide and while lifting up remove the head restraint.
Store the head restraint in a secure location in the vehicle. To re-install
the head restraint, line the posts up in the holes on the seat back with
the head restraint strap facing the outside of the vehicle and push down
until the head restraint locks into place. Lift gently to ensure it is locked
into place.
Refer to Safety seats for children later in this chapter.
WARNING: If the head restraint has been removed from a
seating position to accommodate a high back child restraint, the
head restraint must be re-installed prior to use of the seat by any other
occupant in order to reduce the risk of personal injury in the event of
a collision.
Check to make sure the child seat is properly secured before each use.
Children 12 and under should be properly restrained in a rear seating
position whenever possible. If all children cannot be seated and
restrained properly in a rear seating position, properly restrain the
largest child in the front seat.
When installing a child safety seat with combination lap/shoulder belts:
• Use the correct safety belt buckle for that seating position.
• Insert the belt tongue into the proper buckle until you hear a snap
and feel it latch. Make sure the tongue is securely fastened in the
buckle.
