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’re 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. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s
safety belt. When you remove the child restraint, be
sure to reconnect the lap and shoulder parts of the belt
so they will be ready to work for an adult or larger
child passenger.
