Chevrolet 2006 Express Van Owner's Manual page 50

Some top tether-equipped child restraints are designed
for use with or without the top tether being attached.
Others require the top tether always to be attached.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached. In the United States, some child restraints
also have a top tether. Be sure to read and follow the
instructions for your child restraint.
If the child restraint does not have a top tether, one can
be obtained, in kit form, for many child restraints. Ask
the child restraint manufacturer whether or not a kit
is available.
