WINDSHIELD GLASS
Removal and Installation
INFOID:0000000009463661
REMOVAL
1. Partially remove the headlining (front edge). Refer to INT-30, "Removal and Installation".
2. Remove inside mirror. Refer to MIR-19, "Removal and Installation"
.
3. Remove the cowl top cover. Refer to EXT-24, "Removal and Installation"
.
4. Remove roof side moldings (LH/RH). Refer to EXT-36, "Removal and Installation"
.
5. Remove windshield glass using piano wire or pow er cutting tool (A) and an inflatable pump bag (B).
• Apply a protective tape around the windshield gla ss to protect the painted surface from damage.
• If the windshield glass is to be reused, mark the body and the glass with matching marks.
• Minimum adhesive coating amount 8 +3,- 0 g/100 mm (8 +3,-0 g/3.9 in) all around.
WARNING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help pre-
vent glass splinters from entering your eyes or cutting your hands.
CAUTION:
• Be careful not to scratch the glass when removing.
• Do not set or stand the glass on its ed ge. Small chips may develop into cracks.
• Apply a protective tape around the windshield glass to protect the painted surface from damage.
INSTALLATION
Installation is in the reverse order of removal.
• If repainting near the windshield flange area, pr otect the flange adhesion area by masking the flange.
• Use a Genuine NISSAN Urethane Adhesive Kit (if availabl e) or equivalent and follow the instructions fur-
nished with it.
• Adhesive shall be continuously applied to assure watert ightness. Glass installation shall be finished within
five minutes after applying the adhesive.
• The start and finish of the urethane adhesive application should be located at the bottom to assure water-
tightness.
• While 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.
• The molding must be installed securely to the windshield glass to avoid looseness and will leave no gap.
• Inform the customer that the vehicle should rema in stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.
WARNING:
• Keep heat and open flames away as primers and adhesive are flammable.
• The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.
• Use in an open, well ventilated location. Avoid br eathing the vapors. They can be harmful if inhaled.
If affected by vapor inhalation, imme diately move to an area with fresh air.
• Driving the vehicle before the urethane adhesive has completely cured may affect the performance
of the windshield in case of an accident.
CAUTION:
• Do not use an adhesive which is past its usable te rm. Shelf life of this product is limited to six
months after the date of manufacture. Carefully a dhere to the expiration or manufacture date printed
on the box or product.
• Keep primers and adhesive in a c ool, dry place. Ideally, they should be stored in a refrigerator.
• Do not leave primers or adhesive cartridge unattended with their caps open or off.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951784
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.
Precaution for WorkINFOID:0000000009463909
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
Precaution for Workin g with HFC-134a (R-134a)INFOID:0000000009463910
WARNING:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refr igerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer to HA-21, "Leak Test"
. To determine the purity
of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant Recovery/Recycling Recharg-
ing equipment and Refrigerant Identifier.
