Cadillac STS 2011 Owner's Manual page 80

Some child restraints that have a top tether 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. 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.
