    • Do not bleach or dye the seat belt webbing. Clean the seat belt webbing only with a mild soap and water solution and a soft brush or cloth.
    • Keep sharp edges and damaging objects away from the seat belts. Avoid bending or damaging any part of the seat belt buckle or latch plate.
    • Replace any seat belts which are cut or damaged in any way.
    • Use only correct seat belt anchor bolts and screws.
       -  Tighten the bolts and the screws to the correct torque value. Refer to Fastener Tightening Specifications .
       - When installing the seat belt anchor bolts, start the bolt by hand in order to ensure that the bolt is threaded correctly.
    • Some seat belts and retractors must be serviced as a set with service replacement parts only. Do not attempt to make repairs to the individual components which are only serviced as a set.
    • Verify that the replacement part number is correct for the vehicle at that seating position. Do not substitute a seat belt from a different seating position.
    • Replace any seat belts which have a visible Caution label instructing replacement.
    • Some seat belts have an Energy Management Loop, which is an overlap of the seat belt webbing that is stitched together. If any of the stitching is separated, replace the seat belt.
