PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AJS001BM
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 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
Precautions for Working with HFC-134a (R-134a)AJS0013V
WARNING:

CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed and compressor malfunction is likely to occur, refer to “CONTAMINATED REFRIGER-
ANT” below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use
Refrigerant Recovery/Recycling Recharging equipment and Refrigerant Identifier.

Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor malfunction is likely to occur.

The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing 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 possi-
ble to minimize the entry of moisture into system.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meet-
ing requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [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
lubricant manufacturers.
–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
CONTAMINATED REFRIGERANT
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 refriger-
ant supply.

Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.

General Refrigerant PrecautionsAJS0013W
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
suffocation.

Do not pressure test or leak 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.
Lubricant PrecautionsAJS0013X

Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
If lubricant other than that specified is used, compressor malfunction is likely to occur.

The specified HFC-134a (R-134a) lubricant 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 con-
necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubricant. With-
out proper sealing, lubricant will become moisture saturated and should not be used.

Avoid breathing A/C refrigerant and lubricant 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 J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recovery
equipment]. If accidental system discharge occurs, ventilate work area before resuming service. Addi-
tional health and safety information may be obtained from refrigerant and lubricant manufacturers.

Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts. Damage
may result.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
O-Ring Part Numbers and Specifications
WARNING:
Make sure 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:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not 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.

Always replace used O-rings.

When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0

O-ring must be closely attached to dented portion of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

Precautions for Leak Detection DyeAJS00141

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 to (J-
41995) pin-point refrigerant leaks.

For your safety and your customer′s satisfaction, read and follow all manufacture′s operating instructions
and precautions prior to performing the 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
during 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 system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C system or A/C system damage may result.

The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
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 this identification
label on the front side of hood.
