2004 Buick Rendezvous Owner's Manual - Page 64

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. If you're using a top strap-equipped child restraint in the second row center bench seat and need to temporarily transport a flat tire for repair, move the child restraint to a rear seat outboard position. See Securing a Child Restraint in a Rear Outside Seat Position on page 1-64 for more on this, including important safety information. 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.
