• Keep refrigerant away from open flames. Poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-

cation.

• Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-

tioning 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 refriger-
ant manufacturers.

Refrigerant Connection

INFOID:0000000003469383

A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
• Expansion valve to evaporator
• Refrigerant pressure sensor to liquid tank

O-RING AND REFRIGERANT CONNECTION

CAUTION:

The new and former refrigerant connections use different O-ring configurations. Never confuse O-
rings since they are not interchangeable. Refrigerant may leak at the connection if a wrong O-ring is
installed.

PRECAUTIONS

WARNING:

Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.

CAUTION:

Observe the following when replacing or cleaning refrigerant cycle components.
• Store it in the same way at it is when mounted on the car when the compressor is removed. Failure

to do so will cause lubricant to enter the low-pressure chamber.

• Always use a torque wrench and a back-up wrench when connecting tubes.
• Immediately plug all openings to prevent entry of dust and moisture after disconnecting tubes.
• Connect the pipes at the final stage of the operation when installing an air conditioner in the vehicle.

Never remove the seal caps of pipes and other components until just before required for connection.

• Allow components stored in cool areas to warm to working area temperature before removing seal

caps. This prevents condensation from forming inside A/C components.

• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Replace always used O-rings.
• Apply lubricant to circle of the O-rings shown in illustration when connecting tube. Be careful not to

apply lubricant to threaded portion.

• O-ring must be closely attached to the groove portion of tube.
• Be careful not to damage O-ring and tube when replacing the O-ring.
• Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is

installed to tube correctly.

• Perform leakage test and make sure that there is no leakage from connections after connecting line.

Disconnect the line and replace the O-ring when the refrigerant leaking point is found. Then tighten
the connections of seal seat to the specified torque.

Service Equipment

INFOID:0000000003469384

RECOVERY/RECYCLING EQUIPMENT

Be certain to follow the manufacturer instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.

ELECTRICAL LEAK DETECTOR

Be certain to follow the manufacturer instructions for tester operation and tester maintenance.

VACUUM PUMP

The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched
OFF after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following.
• Vacuum pumps usually have a manual isolator valve as part of the

pump. Close this valve to isolate the service hose from the pump.

• Use a hose equipped with a manual shut-off valve near the pump

end for pumps without an isolator. Close the valve to isolate the
hose from the pump.

• Disconnect the hose from the pump if the hose has an automatic

shut-off valve. As long as the hose is connected, the valve is open
and lubricating oil may migrate.

Some one-way valves open when vacuum is applied and close
under no vacuum condition. Such valves may restrict the ability of
the pump to create a deep vacuum and are not recommended.

HAC-238

< PRECAUTION >

[WITH 7 INCH DISPLAY]

PRECAUTIONS

Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2

″

-16 ACME threaded connections for ser-

vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.

SERVICE HOSES

Be certain that the service hoses display the markings described
(colored hose with a black stripe). All hoses must equip positive
shut-off devices (either manual or automatic) near the end of the
hoses opposite to the manifold gauge.

SERVICE COUPLERS

Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers do
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharge and contamination may
occur.

REFRIGERANT WEIGHT SCALE

Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. The hose fitting must
be 1/2

″

-16 ACME if the scale controls refrigerant flow electronically.

CHARGING CYLINDER

Use of a charging cylinder is not recommended. Refrigerant may be vented into the air from the top valve of
the cylinder when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than
that of an electronic scale or of quality recycle/recharge equipment.

CAUTION:

• Plug all openings to prevent moisture and foreign matter from entering.
• Store it in the same way at it is when mounted on the car when the compressor is removed.
• Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing the

compressor. Refer to 

HA-25, "Maintenance of Lubricant Quantity"

.

• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth

moistened with thinner if the surface is contaminated with lubricant.

• Turn the compressor shaft by hand more than five turns in both directions after compressor service

operation. This equally distributes lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.

• Apply voltage to the new compressor and check for normal operation after replacing the compressor

magnet clutch.

FLUORESCENT LEAK DETECTOR

FLUORESCENT LEAK DETECTOR

General Precautions

INFOID:0000000003469386

CAUTION:

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

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

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

the fluorescent dye.

• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).

The fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.

• Read and follow all manufacture operating instructions and precautions prior to performing the work

for the purpose of safety and customer satisfaction.

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

sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).

• Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis-

diagnosis during future service.

• Never allow dye to come into contact with painted body panels or interior components. Clean imme-

diately with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.

• Never spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Never 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. Never use

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

• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-

tion occurs.

IDENTIFICATION

NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.

IDENTIFICATION LABEL FOR VEHICLE

Vehicles with factory installed fluorescent dye have an identification label on the front side of hood.

PRECAUTIONS

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

INFOID:0000000004788566

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 “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.

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 “SRS AIRBAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

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

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.
