If the position you are using has an adjustable headrest or head restraint and you are using a single tether, route the tether under the headrest or head restraint and in between the headrest or head restraint posts. 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 the child restraint to make sure it is compatible with this vehicle. If the child restraint has the LATCH system, see Lower Anchors and Tethers for Children (LATCH) on page 2‑39 for how and where to install the child restraint using LATCH. If a child restraint is secured in the vehicle using a safety belt and it uses a top tether, see Lower Anchors and Tethers for Children (LATCH) on page 2‑39 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. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. 3. Push and pull the child restraint in different directions to be sure it is secure. 2-45
