Seat Belt Inspection

AFTER A COLLISION

WARNING:

Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN 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 colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner
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 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 dam-
age or distortion and repair as 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 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. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should

sound for about seven seconds.

b. Fasten driver’s seat belt. The seat belt warning lamp should go out and the chime (if sounding) should

stop.

If the seat belt warning lamp is blinking, conduct self-diagnosis using CONSULT-II, and seat belt warning
lamp. Refer to “Self-diagnosis”, “TROUBLE DIAGNOSES — Supplemental Restraint System (SRS)”,
RS-39.

2. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
3. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Ensure guide swiv-

els freely and that belt lays flat and does not bind in guide. Ensure height adjuster operates properly and
holds securely.

SRS353

Check retractor operation:

Fully extend the seat belt webbing and check for twists, tears
or other damage.

Allow the seat belt to retract. Ensure that belt returns smoothly
and completely into the retractor. If the seat belt does not
returns smoothly, wipe the inside of the loops with a clean
paper cloth etc. because dirt built up in the loops of the upper
anchors can cause the seat belts to retractor slowly.

Fasten the seat belt. Pull firmly on belt and buckle to ensure
belt remains latched. Unfasten seat belt. Ensure belt releases
freely and buckle button returns to original position.

Repeat steps above as 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 of the Emergency Locking Retractors (ELR) type. In an emergency (sudden
stop) the retractor will lock and prevent the belt 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 belt is then retracted partially, the ALR mode
automatically locks the seat belt in a specific position so the belt 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 using the following test(s) to determine if a retractor assembly is operating
properly.

ELR function stationary check

Grasp the shoulder belt and pull forward quickly. The retractor should lock and prevent the belt from extend-
ing further.

ALR function stationary check

1. Pull out entire length of seat belt from retractor until a click is heard.
2. Retract the belt partially. A clicking noise should be heard as the belt retracts indicating retractor is in the

Automatic Locking Retractors (ALR) mode.

3. Grasp the seat belt and try to pull out of retractor. Belt must lock and not extend further. If NG, replace the

retractor assembly.

4. Allow the entire length of belt to retract to cancel the ALR 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. DO NOT perform the following test
on wet or gravel roads or on public streets and highways. This could result in an accident and seri-
ous personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten driver’s seat belt. Buckle a passenger into the seat for the belt.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of the pending sudden stop

and the driver and passenger must be prepared to brace themselves in the event the retractor does not
lock. Apply brakes firmly and make a very hard stop.

During the stop, seat belts should lock and not extend. If the seat belt retractor assembly does not lock, per-
form the retractor off-vehicle check.
