Safe DrivingMost child seats are LATCH-compatible (L ower Anchors and Tethers for Children).
Some have a rigid-type connector, while ot hers have a flexible-type connector. Both
are equally easy to use. Some existing and previously owned child seats can only be
installed using the seat belt. Whichever type you choose, follow the child seat
manufacturer’s use and care instructions including recommended expiration dates
as well as the instructions in this manual. Proper installation is key to maximizing
your child’s safety.
In seating positions and vehicles not equipped with LATCH, a LATCH-compatible
child seat can be installed using the seat belt and a top tether for added security.
This is because all child seats are required to be designed so that they can be secured
with a lap belt or the lap part of a lap/sh oulder belt. In addition, the child seat
manufacturer may advise that a seat belt be used to attach a LATCH-compatible seat
once a child reaches a specified weight. Please read the child seat owner’s manual
for proper installation instructions.
■Important consideration wh en selecting a child seat
Make sure the child seat meets th e following three requirements:
• The child seat is the correct type and size for the child.
• The child seat is the correct type for the seating position.
• The child seat is compliant with Federa l Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Standard 213.
■Selecting a Child Seat1 Selecting a Child Seat
Installation of a LATCH-compatible child seat is
simple.
LATCH-compatible child s eats have been developed
to simplify the installati on process and reduce the
likelihood of injuries caused by incorrect installation.
