2004 Cadillac CTS Owner's Manual - Page 46

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 top strap 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. Top Strap Anchor Location The top strap anchors are located on the filler panel behind the rear seat head restraints. In order to access the anchors, you'll have to open the covers. Do not use a child restraint with a top strap in the right front passenger's position because there is no place to anchor the top strap. 1-40
