REMOVAL

1. Remove the luggage side lower and upper finisher. Refer to 

INT-25, "Removal and Installation"

.

2. Disconnect the antenna.
3. If the window glass is to be reused, mark the body and the glass with mating marks.

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.

4. Remove the glass using piano wire or power cutting tool and an inflatable pump bag.

CAUTION:

• When the side window glass is to be reused, do not use a cutting knife or power cutting tool.

• Be careful not to scratch the glass when removing.

• Do not set or stand the glass on its edge. Small chips may develop into cracks. 

INSTALLATION

Installation is in the reverse order of removal. 

• Use a genuine NISSAN Urethane Adhesive Kit (if available) or equivalent and follow the instructions fur-

nished with it.

• 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.

• Check gap along bottom to confirm that glass does not contact sheet metal.

• Inform 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.

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 breathing the vapors. They can be harmful if inhaled.

If affected by vapor inhalation, immediately move to an area with fresh air.

• Driving the vehicle before the urethane adhesive has completely cured may affect the performance

of the glass in case of an accident.

CAUTION:

• Do 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.

• Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.

• Do not leave primers or adhesive cartridge unattended with their caps open or off.

• The 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 humidity. The curing time will increase

under lower temperatures and lower humidities.

Repairing Water Leaks for Side Window Glass

Leaks can be repaired without removing or reinstalling glass.

If water is leaking between urethane adhesive material and body or glass, determine the extent of leakage.

This can be done by applying water to the side window area while pushing glass outward.

To stop leak, apply primer (if necessary) and then urethane adhesive to the leak point.

PRECAUTIONS

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

INFOID:0000000007356291

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 SRS, 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.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric 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 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000007356292

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

 position.

• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing work. If

DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the 

″

ACC

″

 position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

4. Perform the necessary repair operation.

″

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT. 

Precaution for Work

INFOID:0000000007833555

• When removing or disassembling each component, be careful 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-reusable part, always replace it with 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, and wring the water out of the cloth to wipe the dirty

area.

Then rub with a soft and 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, and wring the water out of the cloth to wipe the detergent off. Then rub with

a soft and 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 Working with HFC-134a (R-134a)

INFOID:0000000007356293

WARNING:

• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants

are mixed compressor failure is likely to occur. Refer to 

HA-4, "Contaminated Refrigerant"

. To deter-

mine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use refrigerant recovery/recy-

cling equipment and refrigerant identifier.

• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If

oil other than that specified is used, compressor failure is likely to occur.

• The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following

handling precautions must be observed:

- When removing refrigerant components from a vehicle, immediately cap (seal) the component to

minimize the entry of moisture from the atmosphere.

- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just

before connecting the components. Connect all refrigerant loop components as quickly as possible

to minimize the entry of moisture into system.

- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without

proper sealing, oil will become moisture saturated and should not be used.

- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.

Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require-

ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or SAE J2209 [HFC-134a (R-134a)

recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming

service. Additional health and safety information may be obtained from refrigerant and oil manufac-

turers.

- Do not allow the refrigerant oil to come in contact with styrofoam parts. Damage may result.

Contaminated Refrigerant

INFOID:0000000007356294

If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:

• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into

the atmosphere.

• Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant

supply.

• Suggest the customer return the vehicle to the location of previous service where the contamination may

have occurred.
