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 is minor and the belts show no damage and continue to operate properly. Not
doing so could result in serious personal injury in an accident. Seat belt assemblies not in use during
a collision must also be replaced if either damage or improper operation is noted. Seat belt pre-ten-
sioners must be replaced even if the seat belts are not in use during a frontal collision in which the air
bags are deployed.
Replace any seat belt assembly (including anchor bolts) if:
 The seat belt was 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 was damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).
 The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
 Anchor bolts are deformed or worn out.
 The seat belt pre-tensioners should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Turn ignition switch ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime
should sound for about six seconds.
b. Fasten driver seat belt. The seat belt warning lamp should turn off and the chime (if sounding) should
stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis with CONSULT-III and air bag warning lamp.
Refer to SRC-10, "
Diagnosis Description".
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. Ensure guide swivels
freely and that webbing lays flat and does not bind in guide. Ensure 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. Ensure 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. Because 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
tauntly 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 looseness or wrinkling.

SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the
retractor locks and prevent the webbing from extending any further. All 3-point type seat belt retractors except
the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also called child
restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt is fully
extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt in a
specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat belt
to fully return into the retractor.
Check the seat belt retractors with the following test(s) to determine if a retractor assembly is operating prop-
erly.
