Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012431985
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 severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the 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.

Precautions For Refrigerant System ServiceINFOID:0000000012431987
WORKING WITH HFC-134a (R-134a)
CAUTION:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal-
function is likely to occur if the refrigerants are mixed, refe r to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant recovery/recycling recharging equi pment and Refrigerant Identifier.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
Compressor malfunction is likely to occur if oil other than that specified is used.
• The specified HFC-134a (R-134a) oi l rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- Cap (seal) the component immediately to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle.
- Do not remove the caps (unseal) unti l just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refr igerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified oil from a sealed container. Reseal containers of oil immediately. Oil becomes
moisture saturated and should no t be used without proper sealing.
- Do not allow oil to come in contact with styrene foam parts. Damage may result.
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Do not breathe 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, usin g certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate work area before resumi ng service if accidental system discharge occurs.
Additional health and safety in formation may be obtained from refrigerant and oil manufacturers.
• Do not release refrigerant into the air. Use ap proved recovery/recycling recharging equipment to
capture the refrigerant each 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 (126° F).
• Do not heat a refrigerant containe r with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
• Do not intentionally drop, puncture or incinerate refrigerant containers.
• Do not refrigerant away from op en flames; poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen; therefore be certain to work in well ventilated areas to prevent suffo- cation.
• 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 heal th and safety information may be obtained from refrigerant manu-
facturers.

• Expansion valve to evaporator
• Refrigerant pressure sensor to liquid tank
WARNING:
Check that all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen 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 as it is when mounted on the vehicle when the compressor is removed. Fail- ure to do so will cause oil 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 stag e of the operation when installing an air conditioner in the vehicle.
Do not remove the seal caps of pipes and other comp onents until just before required for connec-
tion.
• 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.
• Remove moisture thoroughly from the refriger ation system before charging the refrigerant.
• Do not reuse O-rings.
• Apply oil to circle of the O-rings shown in illust ration when connecting tube. Be careful not to apply
oil 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 leak test and make sure that there are no leaks from connections after connecting line. Dis-
connect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten
connections of seal seat to the specified torque.
CONTAMINATED REFRIGERANT
Take appropriate steps shown below if a refrigerant other than pure HFC-134a (R-134a) is identified in
a vehicle:
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
• Explain that recovery of the contaminated refri gerant could damage service equipment and refrigerant sup-
ply.
• Suggest the customer return the vehicle to the locati on of previous service where the contamination may
have occurred.
• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Do not
recover contaminated refrigerant into the existing service equipment. Contact a local refrigerant prod-
uct retailer for available service if the facility does not have dedicated recovery equipment. 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.

< PRECAUTION >
PRECAUTIONS
• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-tomer Affairs for further assistance.
COMPRESSOR
CAUTION:
• Cap or plug all openings to prevent moisture and fo reign matter from entering.
• Store it in the same way as it is when moun ted on the car when the compressor is removed.
• Follow “Maintenance of Oil Level” exactly when replacing or repairing compressor. Refer to HA-22,
"Description".
• Keep friction surfaces between clut ch and pulley clean. Wipe it off by using a clean waste cloth
moistened with thinner if the su rface is contaminated with oil.
• Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes oil e qually inside the compressor. Let the engine idle and operate the
compressor for one hour after the compressor is installed.
• Apply voltage to the new one and check for norma l operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leaks. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leaks.
• 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 l eak detector (SST: J-41995).
The fluorescent dye leak detector sh ould be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leaks.
• Read and follow all manufacture’s operating inst ructions and precautions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired becau se of dye seepage. The compres-
sor shaft seal should only be repaired after confi rming the leak with an electrical leak detector (SST:
J-41995).
• Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiag-
nosis during a future service.
• Do not allow dye to come into contact with painted body panels or interior components. Clean imme- diately with the approved dye cl eaner if dye is spilled. 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 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 fo r three or more years unless a compressor malfunc-
tion occurs.
NOTE: Identification
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.

The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure. Vacuum
pump oil may migrate out of the pump into the service hose. This is
possible when the pump is switc hed OFF after evacuation (vacuum-
ing) 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 pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
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 oils.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe) . All hoses must be equipped with
positive shut-off devices (either manual or automatic) near the end of
the hoses opposite to the manifold gauge.

< PRECAUTION >
PRECAUTIONS
Do not attempt to connect HFC-134a (R-134a) service couplers to
the 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, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. The hose fitting must be 1/
2 ″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
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.
