Cadillac 2008 STS Owner's Manual page 43

Your child restraint may have a single tether (A) or a
dual tether (C). Either will have a single attachment (B)
to secure the top tether to the anchor.
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.
