SSS0646 SSS0647 SSS0638 Forward-facing rigid-mounted - step 3 3. The back of the child restraint should be secured against the vehicle seatback. If necessary, adjust or remove the headrest to obtain the correct child restraint fit. If the headrest is removed, store it in a secure place. Be sure to reinstall the headrest when the child restraint is removed. See "Adjustable headrest" in this section for headrest adjustment information. If the seating position does not have an adjustable headrest and it is interfering with the proper child restraint fit, try another seating position or a different child restraint. Forward-facing - step 4 4. For child restraints that are equipped with webbing-mounted attachments, remove any additional slack from the anchor attachments. Press downward and rearward firmly in the center of the child restraint with your knee to compress the vehicle seat cushion and seatback while tightening the webbing of the anchor attachments. 5. Tighten the tether strap according to the manufacturer's instructions to remove any slack. Forward-facing - step 6 6. After attaching the child restraint, test it before you place the child in it. Push it from side to side while holding the child restraint near the LATCH attachment path. The child restraint should not move more than 1 inch (25 mm), from side to side. Try to tug it forward and check to see if the LATCH attachment holds the restraint in place. If the restraint is not secure, tighten the LATCH attachment as necessary, or put the restraint in another seat and test it again. You may need to try a different child restraint. Not all child restraints fit in all types of vehicles. 1-28 Safety - Seats, seat belts and supplemental restraint system
