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 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 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. The retractor should lock and prevent the belt from
extending further.
ALR Function Stationary Check
1.
Pull out the entire length of the seat belt from the retractor until a click is heard.
2.
Retract the webbing partially. A clicking noise should 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 retract 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 paved and dry. Never perform the following test on
wet or gravel roads or on public streets and highways. 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 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.
SEAT BELT RETRACTOR OFF-VEHICLE CHECK

SEAT BELT BUCKLE : Inspection
INFOID:0000000005513466
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. Fail-
ure to do so could result in serious personal injury 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 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 buck-
les 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-tensioner 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 follows:
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, conduct self-diagnosis using CONSULT-III and air bag warning
lamp. Refer to
SRC-17, "Diagnosis Description"
.
3.
Check that the seat belt retractor, seat belt anchor and buckle bolts are tightened firmly.
4.
Repeat steps above if necessary to check the other seat belts.
