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 da mage or improper operation was noted. Seat belt
pre-tensioners should be replaced even if the seat be lts were not in use during a frontal collision in
which the air bags were deployed.

 The seat belt is in use at the time of a collision (exc ept 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. to rn 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.

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 th e belts show no damage and continue to operate properly. Fail-
ure to do so could result in seri ous personal injury in an accident. Seat belt assemblies not in use dur-
ing a collision should also be re placed if either damage or improper operation was noted. Seat belt
pre-tensioners should be replaced even if the seat be lts 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 (e xcept 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. to rn 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 t he seat belts were not in use during the collision in
which the air bags were deployed.
PRELIMINARY CHECKS
1. Check that the seat belt retractor, s eat belt anchor and buckle bolts are tightened firmly.
2. Check retractor operation:
a. Fully extend the seat belt webbing and c heck 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 that upper anchors can cause the seat belts to retract slowly.
c. Fasten the seat belt. Check that seat belt returns sm oothly 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.
3. 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 Retr actors (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 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 p aved 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 pending sudden stop
and the driver and passenger must be prepared to brac e 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
1. Remove the second seat belt retractor. Refer to SB-13, "SEAT BELT RETRACTOR : Removal and Instal-
lation".
2. Slowly pull out webbing while tilting the retracto r assembly forward from the mounted position without
twisting the retractor assembly as shown in the figure.
a. Outer seat belt retractor  The webbing can be pulled out when the angle (A) is 15degrees or less.
 The webbing cannot be pulled out when the angle (B) is 27
degrees or more.
b. Center seat belt retractor  The webbing can be pulled out when the angle (A) is 25
