Preliminary Checks

  1. Check the seat belt warning lamp/chime for proper operation as follows:
    1. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should sound for about six seconds.
    2. Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should stop.
  2. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT and air bag warning lamp. Refer to SRS OPERATION CHECK .
  3. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
  4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Make sure guide swivels freely and that webbing lays flat and does not bind in guide. Make sure height adjuster operates properly and holds securely.
  5. Check retractor operation:
    1. Fully extend the seat belt webbing and check for twists, tears or other damage.
    2. Allow the seat belt to retract. Make sure that webbing returns smoothly and completely into the retractor. If the seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth. Dirt built up in the loops of the upper anchors can cause the seat belts to retract slowly.
    3. Fasten the seat belt. Check that the seat belt returns smoothly and completely to the retractor. If the webbing does not return smoothly, the cause may be an accumulation of dust or dirt. Use the "SEAT BELT TAPE SET" and perform the following steps.

    Inspect the front seat belt through-anchor

    1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
    2. Use a clip or other device to hold the seat belt at the center pillar webbing opening.
    3. Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull it taunt while moving it up and down several times along the webbing opening surface to move matter stuck there.
    4. Any dirt that can not be removed with the wire can be removed by cleaning the opening with a clean cloth.
    5. Apply tape at the point where the webbing contacts the through-anchor webbing opening.
      NOTE: Apply the tape so that there is no looseness or wrinkling.
    6. Remove the clip holding the seat belt and check that the webbing returns smoothly.
  6. Repeat steps above as necessary to check the other seat belts.
