PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000001697632

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 SR and SB section of this Service Man-
ual.

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 SR, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.

Handling for Adhesive and Primer

INFOID:0000000001697633

• Do not use an adhesive which is past its usable date. Shelf life of this product is limited to six months after

the date of manufacture. Carefully adhere to the expiration or manufacture date printed on the box.

• Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
• Open the seal of the primer and adhesive just before application. Discard the remainder.
• Before application, be sure to shake the primer container to stir the contents. If any floating material is found,

do not use it.

• If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with

soap.

• When using primer and adhesive, always observe the precautions in the instruction manual.

Filament Check

INFOID:0000000001697630

When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.

Attach probe circuit tester (in Volt range) to middle portion of
each filament.

If a filament is burned out, circuit tester registers 0 or battery
voltage.

To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.

• Drawing pen
• Heat gun
• Alcohol
• Cloth

REPAIRING PROCEDURE

Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.

Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.

Place ruler on glass along broken line. Deposit conductive silver
composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.

After repair has been completed, check repaired wire for conti-
nuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.

Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.
