Seat belt retractor : Inspection

AFTER A COLLISION

WARNING:
Inspect all seat belt assemblies including retractors and attached hardware after any collision

.

NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation was noted. Seat belt pre-tensioners should be replaced even if the seat belts were not in use during a frontal collision in which the air bags were deployed.

Replace any seat belt assembly (including anchor bolts) if: The seat belt is in use at the time of a collision (except for minor collisions and the belts, retractors and buckles show no damage and continue to operate properly).

The seat belt is damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).

The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or distortion and repair if necessary before installing a new seat belt assembly.

Anchor bolts are deformed or worn out.

The seat belt pre-tensioners must be replaced even if the seat belts were not in use during the collision in which the air bags were deployed.

PRELIMINARY CHECKS

1. Check the seat belt warning lamp for proper operation as per the following: a. Turn ignition switch ON. The seat belt warning lamp should illuminate.

b. Fasten driver seat belt. The seat belt warning lamp should turn OFF.

2. If the air bag warning lamp is blinking, perform self-diagnosis with CONSULT-III and air bag warning lamp. Refer to SRC-12, "Description".

3. Check that the seat belt retractor, seat belt anchor and buckle bolts are tightened firmly.

4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Check that guide swivels freely and that webbing lays flat and does not bind in guide. Check that height adjuster operates properly and holds securely.

5. Check retractor operation: a. Fully extend the seat belt webbing and check for twists, tears or other damage.

b. Allow the seat belt to retract. Check 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 build-up in the loops of the upper anchors can cause the seat belts to retract slowly.

c. Fasten the seat belt. Check that 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. Fix the seat belt at the center pillar webbing opening with a clip or other device.

3. Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull it tightly while moving it up and down several times along the webbing opening surface to remove dirt stuck there.

4. Any dirt that cannot 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 slack or wrinkling.

6. Remove the clip fixing the seat belt and check that the webbing returns smoothly.

6. Repeat steps above if necessary to check the other seat belts.

SEAT BELT RETRACTOR ON-VEHICLE CHECK

Emergency Locking Retractors (ELR) NOTE
