AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies in cluding retractors and attaching 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 th e belts show no damage and continue to operate properly. Fail-
ure to do so could result in serious personal inju ry in an accident. Seat belt assemblies not in use dur-
ing a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-
tensioners should 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 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-tensioner should be replaced even if t he 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 for proper operation 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 and air bag warning lamp. Refer to SRC-14, "
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 retu rns 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 accu mulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
d. Inspect the front seat belt D-ring anchor 1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Hold the seat belt at the center pillar webbing opening with a clip or other device.
3. Pass a thin wire through the D-ring 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 D-ring anchor webbing opening. NOTE:
Apply the tape so that there is no slack or wrinkling.
6. Remove the clip holding 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) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the
retractor will lock and prevent the webbing from extendi ng any further. All 3-point type seat belt retractors
except the driver seat belt also have an Automati c 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 part ially, 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 wind back into the retractor.
Check the seat belt retractors with the following test(s ) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
Grasp the shoulder webbing and pull forward quickly. T he retractor should lock and prevent the belt from
extending further.
ALR Function Stationary Check
1. Pull out the entire length of seat belt from retractor until a click is heard.
2. Retract the webbing partially. A clicking noise shoul d be heard as the webbing retracts, indicating that the
retractor is in the Automatic Locking Retractors (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If it
does not operate normally, replace the retractor assembly.
4. Allow the entire length of the webbing to re tract to cancel the automatic locking mode.
ELR Function Moving Check
WARNING:
Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be p aved and dry. Never perform the following test on
wet or gravel roads or on public streets and highw ays. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event that the
retractor does not lock.
1. Fasten driver seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h ( 10 mph). Notify any passengers of a pending sudden stop
and the driver and passenger must be prepared to brace themselves in the event that the retractor does
not lock. Apply brakes firmly and make a very hard stop.
During stopping, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock,
perform the retractor off-vehicle check.
FRONT SEAT BELT RETRACTOR OFF-VEHICLE CHECK
1. Remove the front seat belt retractor. Refer to SB-9, "SEAT BELT RETRACTOR : Removal and Installa-
tion".
2. Slowly pull out webbing while tilting the seat belt re tractor forward from the mounted position without twist-
ing the seat belt retractor as shown.
A : The webbing can be pulled out if the retractor is tilted 17 °
degree or less.
B : The webbing can not be pulled out if the retractor is tilted 27°
degrees or more.
NOTE:
A and B show tilting angles.
: Front
3. Replace the seat belt retractor if it does not operate within specifications.
