3-48 Seats and Restraints { WARNING If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked. 1.5. Lift the seatback up and push it rearward. Then lower the seat cushion until the seatback and the seat cushion lock into position. 2. Attach the lower attachments to the lower anchors. If the child restraint does not have lower attachments or the desired seating position does not have lower anchors, secure the child restraint with the top tether and the safety belts. Refer to your child restraint manufacturer instructions and the instructions in this manual. If the position you are using has an adjustable headrest or head restraint and you are using a dual tether, route the tether around the headrest or head restraint. If the position you are using has an adjustable headrest or head restraint and you are using a single tether, raise the headrest or head restraint and route the tether under the headrest or head restraint and in between the headrest or head restraint posts. 1.4. Attach the top tether attachment to the top tether anchor.
