Lower Anchorages and Top Tethers for Children (LATCH System) Third Row 50/50 Split Bench Seat Your vehicle has the LATCH system. You will find anchors in 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. 1-59
