Lower Anchorages and Top Tethers for Children (LATCH System) In order to use the system, you need either a forward-facing child restraint that has attaching points (B) at its base and a top tether anchor (C), or a rear-facing child restraint that has attaching points (B), as shown here. U Your vehicle has the LATCH system. You'll find anchors (A) in all three rear seat positions. To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system will have a label sewn into the seatback at each anchor point. 1-44
