FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR 
BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000005716267

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” 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 AIR BAG”.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

FOR USA AND CANADA : Precaution for Seat Belt Service

INFOID:0000000005513462

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-186, "Diagnosis Description"

.

• 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/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 are not in use during a frontal collision in which
the air bags are deployed.

• 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.

• 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.).

PRELIMINARY CHECKS

1.

Check the seat belt warning lamp for proper operation as pen 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-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.

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 and other damage.

b.

Allow the seat belt to retract. Check 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. 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 (19.685 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
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 through-anchor webbing opening. 
NOTE:
Apply the tape so that there is no slack or wrinkling.

6.

Remove the clip fixing the seat belt and check that the webbing returns smoothly.

6.

Repeat steps above if necessary to check the other seat belts.
