Chevrolet 2005 Equinox Owner's Manual page 48

In Canada, the law requires that forward-facing child
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.
1-42
Anchor the top strap to an anchor point specified in
Top Strap Anchor Location on page 1-43. 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.
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.
