Lower Anchorages and Top Tethers for Children (LATCH System) Your vehicle has the LATCH system. There are anchors for the center and right side passenger second row seating positions for bench seats, and the outboard passenger positions for bucket seats. 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. Third Row 50/50 Split Bench Seat Your vehicle has a top strap anchor for each seating position in the second row, and for the center seating position in the third row. The anchors are located at the bottom rear of the seat cushion. Do not secure a child restraint with a top strap in the right front passenger's position or in the third row outboard seating positions 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 these positions. 1-56
