Top Strap Anchor Location Envoy Anchor brackets for the rear seat positions are located on the floor in the cargo area of your vehicle (Envoy only). Do not use the rear tie-down brackets near the liftgate for top strap tethers. Do not secure a child restraint with a top strap in the right front passenger's position if a national or local law requires that the top strap be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored. There is no place to anchor the top strap in this position. 1-39
