Do not secure a child restraint with a top strap in the right front passenger's position or at the third row driver's side position (vehicles with a full bench seat) 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. Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle has the LATCH system. You will find anchors in the second row outboard bucket seats, the 40 side of the 60/40 split bench seat, and both second row captain's chairs. Third Row (Stowable Seat) The anchor bar for the stowable bench seat is located on the passenger's side of the crossbar. Use the center seating position to use the anchor bar properly. If the convenience center is in the vehicle, you must lift the tray sill to use the anchor. This system, designed to make installation of child restraints easier, does not use the vehicle's safety belts. Instead, it uses vehicle anchors and child restraint attachments to secure the restraints. Some restraints also use another vehicle anchor to secure a top tether strap. 1-62
