10. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt

Check to make sure the child seat is properly secured before each use.
Installing a child safety seat in the center seating position with
adjustable lap belt
1. Lengthen the lap belt. To lengthen the belt, hold the tongue so that its
bottom is perpendicular to the direction of webbing while sliding the
tongue up the webbing.
2. Place the child safety seat in the center seating position.
3. Route the tongue and webbing through the child seat according to the
child seat manufacturer's instructions.
4. Insert the belt tongue into the proper buckle for the center seating
position until you hear a snap and feel it latch. Make sure the tongue is
securely fastened to the buckle by pulling on tongue.
5. Push down on the child seat while pulling on the loose end of the lap
belt webbing to tighten the belt.
6. Before placing the child into the child seat, forcibly tilt the child seat
from side to side and in forward direction to make sure that the seat is
held securely in place. If the child seat moves excessively, repeat steps
5 through 6, or properly install the child seat in a different position.

Attaching safety seats with tether straps

Some manufacturers make safety seats that include a tether strap that
goes over the back of the vehicle seat and attaches to an anchoring
point. Other manufacturers offer the tether strap as an accessory.
Contact the manufacturer of your child safety seat for information about
ordering a tether strap.
