2004 Buick LeSabre Owner's Manual - Page 44

Anchor the top strap to an anchor point specified in Top Strap Anchor Location on page 1-38. 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. Top Strap Anchor Location Your vehicle has top strap anchors already installed for the rear seating positions. You'll find them behind the rear seat on the filler panel. 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. {CAUTION: Each top tether bracket is designed to anchor only one child restraint. Attaching more than one child restraint to a single bracket could cause the anchor to come loose or even break during a crash. A child or others could be injured if this happens. To help prevent injury to people and damage to your vehicle, attach only one child restraint per bracket. 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. In order to get to a bracket, you'll have to open the trim cover. 1-38
