Your vehicle has top strap anchors already installed for the rear seating positions. An anchor bar for a top strap is located at the rear of the seat cushion for each second row outboard seating position. The anchor bar for the center position bench seat is located on the floor behind the second row seats. If the vehicle has the extended rear convenience center, you need to remove a plastic plug and look under the convenience center to find the anchor bar for the center position bench seat. 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. Second Row Center Position Bench Seat with Third Row Seat If the vehicle has a third row seat and the seatback is upright, there is an anchor strap located between the third row seatback and cushion to anchor the child restraint for the second row center position bench seat. 1-60
