6. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may find it helpful to use your
knee to push down on the child restraint
as you tighten the belt.
7. If your child restraint has a top tether, and the
position that you are using has a top tether
anchor, attach and tighten the top tether to the
top tether anchor. Refer to the instructions
that came with the child restraint and to Lower
Anchors and Tethers for Children (LATCH)
on page 61.
8. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the
vehicle's safety belt and let it go back all the way.
The safety belt will move freely again and be
ready to work for an adult or larger child
passenger.
When the safety belt is not in use, slide the latch
plate up the safety belt webbing. The latch
plate should rest on the stitching on the safety
belt, near the guide loop on the side wall.
