Seats and Restraints 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. If the child restraint does not have the LATCH system, you will be using the safety belt to secure the child restraint in this position. Be sure to follow the instructions that came with the child restraint. Secure the child in the child restraint when and as the instructions say. If more than one child restraint needs to be installed in the rear seat, be sure to read Where to Put the Restraint on page 3‑41. 1. Put the child restraint on the seat. If the head restraint interferes with the proper installation of the child restraint, the head restraint may be removed. See "Head Restraint Removal and 3. Push the latch plate into the buckle until it clicks. Reinstallation" under Lower Anchors and Tethers for Children (LATCH System) on page 3‑42. 2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle's safety belt through or around the restraint. The child restraint instructions will show you how. 3-51 Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary. 4. Pull the shoulder belt all the way out of the retractor to set the lock. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor.
