PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003949049
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution for Seat Belt ServiceINFOID:0000000003848851
CAUTION:
 Before removing the front seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect
both battery cables and wait at least 3 minutes.
 Never use electrical test equipment for front seat belt pre-tensioner connector.
 After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat belt
pre-tensioner connector, check the system function. Refer to SRC-10, "
Diagnosis Description".
 Deploy front seat belt pre-tensioner assembly before disposing. Refer to SR-25, "
Caution for Air Bag
Module and Seat Belt Pre-tensioner"
 Never use disassembled buckle or seat belt assembly.
 Replace anchor bolts if they are deformed or worn out.
 Never oil tongue and buckle.
 If any component of seat belt assembly is questionable, never repair. Replace the entire seat belt
assembly.
 If webbing is cut, frayed or damaged, replace seat belt assembly.
 When replacing seat belt assembly, use a Genuine NISSAN seat belt assembly.
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attached hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was 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
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 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).
 The seat belt attaching point is 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 front seat belt pre-tensioner must be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.

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.
