Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS000T0
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WAR NIN G:
lTo 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.
lImproper 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.
lDo 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 harness connectors.
Precautions for Working with HFC-134a (R-134a)EJS000T1
WAR NIN G:
lUse 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 failure is likely to occur.
lThe 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-
bletominimizetheentryofmoistureintosystem.
–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 R-134a from the A/C system, using certified service equipment meeting require-
ments of SAE J2210 (R-134a recycling equipment), or J2209 (R-134a recovery equipment). If acci-
dental 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.
General Refrigerant PrecautionsEJS000T2
WAR NIN G:
lDo not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
lAlways wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
lDo not store or heat refrigerant containers above 52°C(125°F).
lDo 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.
lDo not intentionally drop, puncture, or incinerate refrigerant containers.
lKeep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
lRefrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
lDo 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 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 man-
ufacturers.
Lubricant PrecautionsEJS000T3
lUse 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 failure is likely to occur.
lThe 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.
lAvoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat.
Remove R-134a from the A/C system, using certified service equipment meeting requirements of SAE
J2210 (R-134a recycling equipment), or J2209 (R-134a recovery equipment). If accidental system dis-
charge occurs, ventilate work area before resuming service. Additional health and safety information may
be obtained from refrigerant and lubricant manufacturers.
lDo not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts. Damage
may result.
Precautions for Refrigerant ConnectionEJS000T4
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
lExpansion valve to cooling unit
lRefrigerant pressure sensor to liquid tank
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
lThe O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance 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
characteristics.
lThe reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facil-
itating piping connections.

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
lWhen connecting tubes, always use a torque wrench and a back-up wrench.
lAfter disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
lWhen 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.
lAllow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
lThoroughly remove moisture from the refrigeration system before charging the refrigerant.
lAlways replace used O-rings.
lWhen 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
lO-ring must be closely attached to dented portion of tube.
lWhen replacing the O-ring, be careful not to damage O-ring and tube.
lConnect 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.
lAfter connecting line, conduct leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten con-
nections of seal seat to the specified torque.
Precautions for Servicing CompressorEJS000T5
lPlug all openings to prevent moisture and foreign matter from entering.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
lWhen replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer toATC-21, "
Maintenance of Lubricant Quantity in Compressor".
lKeep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.
lAfter compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.

PREPARATION
HFC-134a (R-134a) Service Tools and Equipment
EJS000TB
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.
