How do I store the harness system when not in use?

To store the harness system, loosen shoulder straps, raise the headrest to its highest position, unbuckle the chest clip and buckle strap, remove the pad and expose the seat back, lift the headrest pad flap out of the way, undo 2 snaps in the headrest pad, pull the bottom seat pad back to expose the plastic shell, open the harness storage door, and store the buckle inside the car seat shell. Then replace the seat pad. (Page 7)
