yellowblue Utility models: Anchor brackets for the rear outside seat positions are located on the floor in the cargo area. CAUTION: Routing the top strap for a child restraint over or under the cargo security shade could cause the shade to come loose and even break. If this happens, the shade could be thrown about the vehicle in a collision or sudden maneuver. You or others could be injured. When anchoring a top strap to a cargo tiedown, be sure to remove the cargo security shade from your vehicle. See "Cargo Security Shade" in the Index. Don't use the front set of tie-down brackets. Anchor the top strap to the rearmost bracket on the same side of the vehicle as the child restraint. 1-52
