If the position you are using has a fixed headrest or head restraint and you are using a dual tether, route the tether around the headrest or head restraint. Securing a Child Restraint in a Rear Seat Position When securing a child restraint in a rear seating position, study the instructions that came with your child restraint to make sure it is compatible with this vehicle. If your child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 1-43 for how to install your child restraint using LATCH. If you secure a child restraint using a safety belt and it uses a top tether, see Lower Anchors and Tethers for Children (LATCH) on page 1-43 for top tether anchor locations. Do not secure a child seat in a position without a top tether anchor if a national or local law requires that the top tether be anchored, or if the instructions that come with the child restraint say that the top strap must be anchored. 3. Push and pull the child restraint in different directions to be sure it is secure. 1-50
