Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS001P3
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.
WAR NIN G:
lTo 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.
lImproper 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.
lDo 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 harness connector.
PrecautionsEIS001P4
lWhen removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.
lWhen removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
lKeep removed parts protected with cloth.
lIf a clip is deformed or damaged, replace it.
lIf an unreusable part is removed, replace it with a new one.
lTighten bolts and nuts firmly to the specified torque.
lAfter re-assembly has been completed, make sure each part functions correctly.
lRemove 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.
lDo not use any organic solvent, such as thinner or benzine.

WINDSHIELD GLASS AND MOLDINGPFP:72700
Removal and InstallationEIS001P5
REMOVAL
1. Remove the front pillar garnish and headlining. Refer toEI-26, "BODY SIDE TRIM"andEI-29, "HEAD-
LINING".
2. Remove the weather–strip on the front pillar.
3. Remove the cowl top cover. Refer toEI-12, "
COWL TOP".
4. Apply a protective tape around the windshield glass to protect the painted surface from damage.
After removing moldings, remove glass using piano wire or power cutting tool and an inflatable pump bag.
lIf a windshield glass is reversed, mark the body and the glass with mating marks.
WA RN ING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
glass splinters from entering your eyes or cutting your hands.
CAUTION:
When a windshield glass is reused, do not use a cutting knife or power cutting tool.
NOTE:
lBe careful not to scratch the glass when removing.
lDo not set or stand the glass on its edge. Small chips may develop into cracks.
INSTALLATION
lUse a genuine Nissan Urethane Adhesive Kit or equivalent and follow the instructions furnished with it.
lWhile the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger compartment air pressure when a door is closed.
lThe molding must be installed securely so that it is in position and leaves no gap.

WINDSHIELD GLASS AND MOLDING
lInform the customer that the vehicle should remain stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.
WAR NIN G:
lKeep heat and open flames away as primers and adhesive are flammable.
lThe materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.
lUse in an open, well ventilated location. Avoid breathing the vapors. They can be harmful if
inhaled. If affected by vapor inhalation, immediately move to an area with fresh air.
lDriving the vehicle before the urethane adhesive has completely cured may affect the perfor-
mance of the windshield in case of an accident.
CAUTION:
lDo not use an adhesive which is past its usable term. 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.
lKeep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
lDo not leave primers or adhesive cartridge unattended with their caps open or off.
lThe vehicle should not be driven for at least 24 hours or until the urethane adhesive has com-
pletely cured. Curing time varies depending on temperature and humidities. The curing time will
increase under higher temperatures and lower humidities.
Repairing Water Leaks for Windshield
Leaks can be repaired without removing and reinstalling glass.
If water is leaking between the urethane adhesive material and body or glass, determine the extent of leakage.
This can be done by applying water to the windshield area while pushing glass outward.
To stop the leak, apply primer (if necessary) and then urethane adhesive to the leak point.

REMOVAL
1. Remove luggage side lower finisher and rear pillar finisher. Refer toEI-26, "BODY SIDE TRIM".
2. Apply protective tape on body panels around side window glass to protect painted surfaces from damage.
3. While removing the clips, remove glass from the vehicle.
INSTALLATION
1. With a knife, scrape off remaining adhesive left around on the
side of vehicle body to as thin and flat as 2 mm(0.08 in).
2. Apply primers.
3. Apply primer on areas where adhesive contacts on the side of vehicle body.
4. After applying primer, apply adhesive along glass edge.
5. Press entire surface of glass lightly to fit it completely.

6. Using a spatula, repair any adhesive overflow or shortage to make the surface smooth.
NOTE:
After installing glass, open the door windows until adhesive has had enough time to cure properly. Do not drive
the vehicle during this period.
7. Check that there is no leak from the outside.
8. Remove protective tape.
9. Install removed parts.
