Third Row An anchor bar for a top strap is located at the rear of the seat cushion for each second and third row outboard seating position, and for the center position of the second row. 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. 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. 1-59
