Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.
1. Make the belt as long as possible by tilting the
latch plate and pulling it along the belt.
2. Put the child restraint on the seat.
3. Run the vehicle's safety belt through or around the
restraint. The child restraint instructions will show
you how.
1-68
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. To tighten the belt, pull its free end while you push
down on the child restraint. If you are using a
forward-facing child restraint, you may find it helpful
to use your knee to push the child restraint as
you tighten the belt.
6. If your child restraint has a top tether, attach and
tighten the top tether to the top tether anchor.
Refer to the instructions that came with the child
restraint and to step five under Lower Anchors and
Tethers for Children (LATCH) on page 1-55.
7. Push and pull the child restraint in different
directions to be sure it is secure.
