Chevrolet 2002 Prizm Owner's Manual page 60

In Canada, the law requires that forward
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints also
have a top strap. If your child restraint has a top strap, it
should be anchored.
Anchor the top strap to one of the following anchor
points. Be sure to use an anchor point located on the
same side of the vehicle as the seating position where
the child restraint will be placed. If you have an
adjustable head restraint, route the topstrap under it.

Once you have the top strap anchored, you'll be ready to
secure the child restraint itself. Tighten the top strap
when and as the child restraint manufacturer's
instructions say.

Your vehicle has top strap anchors already installed for
