5 . 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.
6. To tighten the belt, pull its free end while you push down on the child
restraint.
7. Push and pull the child restraint in different directions to be sure it is
secure. If the child restraint isn't secure, turn the latch plate over and
buckle it again. Then see if it is secure. If it isn't, secure the restraint in
a different place in the vehicle and contact the child restraint maker for
their advice about how to attach the child restraint properly.
To remove the child restraint, just unbuckle the vehicle's safety belt. It will
be ready to work for an adult or larger child passenger.
