REMOVALNBBT0019S01After removing moldings, remove glass using piano wire or power
cutting tool and an inflatable pump bag.
WARNING:
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:
IBe careful not to scratch the glass when removing.
IDo not set or stand the glass on its edge. Small chips may
develop into cracks.
INSTALLATIONNBBT0019S02IUse a genuine Nissan Urethane Adhesive Kit or equivalent
and follow the instructions furnished with it.
IWhile the urethane adhesive is curing, open a door win-
dow. This will prevent the glass from being forced out by
passenger compartment air pressure when a door is
closed.
IThe molding must be installed securely so that it is in
position and leaves no gap.
IInform the customer that the vehicle should remain sta-
tionary until the urethane adhesive has completely cured
(preferably 24 hours). Curing time varies with temperature
and humidity.
WARNING:
IKeep heat and open flames away as primers and adhesive
are flammable.
IThe materials contained in the kit are harmful if
swallowed, and may irritate skin and eyes. Avoid contact
with the skin and eyes.
IUse 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.
IDriving the vehicle before the urethane adhesive has com-
pletely cured may affect the performance of the wind-
shield in case of an accident.
CAUTION:
IDo 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.
IKeep primers and adhesive in a cool, dry place. Ideally,
they should be stored in a refrigerator.
IDo not leave primers or adhesive cartridge unattended
with their caps open or off.
IThe vehicle should not be driven for at least 24 hours or
until the urethane adhesive has completely cured. Curing
time varies depending on temperature and humidities. The
curing time will increase under higher temperatures and
lower humidities.

Repairing Water Leaks for WindshieldNBBT0019S0301Leaks 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.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NBEC0002The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to INFINITI QX4 is as follows:
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt
pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
IFor a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring
harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
ITo 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 INFINITI dealer.
IImproper 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 RS section.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for On Board Diagnostic (OBD)
System of Engine and A/T
NBEC0003The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
IBe sure to turn the ignition switch OFF and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc.
will cause the MIL to light up.
IBe sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
ICertain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector. For description and how to disconnect, refer to EL-6, ªHARNESS
CONNECTOR (SLIDE-LOCKING TYPE)º.
IBe sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MIL to light up due to the short circuit.
IBe sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfunction of the fuel injection system, etc.
IBe sure to erase the unnecessary malfunction information (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
