REMOVAL

1.

Remove the luggage side upper finisher. Refer to 

INT-23, "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.

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

INFOID:0000000003935690

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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004448865

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-III 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.

5.

When the repair work is completed, return the ignition switch to the 

″

LOCK

″

 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-III. 

Precaution for Working with HFC-134a (R-134a)

INFOID:0000000003935691

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-

2009 Pathfinder

HA-4

< PRECAUTION >

PRECAUTIONS

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:0000000003935692

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.

• If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-

ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility does
not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available ser-
vice. This refrigerant must be disposed of in accordance with all federal and local regulations. In addition,
replacement of all refrigerant system components on the vehicle is recommended.

• If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus-

tomer Affairs for further assistance.

General Refrigerant Precaution

INFOID:0000000003935693

WARNING:

• Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the

refrigerant every time an air conditioning system is discharged.

• Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air

conditioning system.

• Do not store or heat refrigerant containers above 52

°

C (125

°

F).

• Do not heat a refrigerant container with an open flame; if container warming is required, place the

bottom of the container in a warm pail of water.

• Do not intentionally drop, puncture, or incinerate refrigerant containers.
• Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
• Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suf-

focation.

• Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-

ing systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have
been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant manu-
facturers.

Precaution for Leak Detection Dye

INFOID:0000000003935694

• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet

(UV) lamp is required to illuminate the dye when inspecting for leaks.

• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of

the fluorescent dye.

• The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-

rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector (J-
41995).

• For your safety and the customer's satisfaction, read and follow all manufacturer's operating instructions and

precautions prior to performing work.

• A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should

only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).

• Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis dur-

ing a future service.

• Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,

clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of
time cannot be removed.

• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not use more than one refrigerant dye bottle (1/4 ounce / 7.4 cc) per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use HFC-

134a (R-134a) leak detection dye in CFC-12 (R-12) A/C systems or CFC-12 (R-12) leak detection dye in
HFC-134a (R-134a) A/C systems or A/C system damage may result.

• The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure occurs.

A/C Identification Label

INFOID:0000000003935695

Vehicles with factory installed fluorescent dye have this identification label on the underside of hood.

Precaution for Refrigerant Connection

INFOID:0000000003935696

A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
• Expansion valve to cooling unit
• Evaporator pipes to evaporator (inside cooling unit)
• Refrigerant pressure sensor

FEATURES OF NEW TYPE REFRIGERANT CONNECTION

• The O-ring has been relocated. It has also been provided with a groove for proper installation. This reduces

the possibility of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the O-
ring is now set vertically in relation to the contacting surface of the mating part to improve sealing character-
istics.

• The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facili-

tating piping connections.
