Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS0010L
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 and SB section 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

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
harness connectors.
Precautions BIS0010M

Disconnect both battery cables in advance.

Do not tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

SQUEAK AND RATTLE TROUBLE DIAGNOSES

FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15 × 25 mm (0.59 × 0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not available through NISSAN Parts Department, can also be used to repair squeaks
and rattles.
UHMW(TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingBIS001TL
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks to
repair the noise.

Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precaution for Seat Belt ServiceBHS0003Q
CAUTION:

Before removing the front seat belt pre-tensioner assembly, turn the ignition switch off, discon-
nect both battery cables and wait at least 3 minutes.

Do not 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 SRS-16, "
SRS Operation Check"
.

Activate front seat belt pre-tensioner assembly before disposing. Refer to SRS-48, "DISPOSAL OF
AIR BAG MODULE AND SEAT BELT PRE-TENSIONER" .

Do not use disassembled buckle or seat belt assembly.

Replace anchor bolts if they are deformed or worn out.

Do not oil tongue and buckle.

If any component of seat belt assembly is questionable, do not repair. Replace the whole 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 attaching 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. 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-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 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).

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 front seat belt pre-tensioners should be replaced even if the seat belts are not in use during the colli-
sion in which the air bags are deployed.
