Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof 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 in¯ation, all maintenance must be performed
by an authorized NISSAN 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 RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Working with HFC-134a
(R-134a)
WARNING:
+CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refriger-
ants must never be mixed, even in the smallest amounts. If the refrigerants are mixed, compres-
sor failure is likely to occur.
+Use only speci®ed lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) com-
ponents. If lubricant other than that speci®ed is used, compressor failure is likely to occur.
+The speci®ed HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The
following handling precautions must be observed:
a: When removing refrigerant components from a vehicle, immediately cap (seal) the component
to minimize the entry of moisture from the atmosphere.
b: 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.
c: Only use the speci®ed lubricant from a sealed container. Immediately reseal containers of
lubricant. Without proper sealing, lubricant will become moisture saturated and should not
be used.
d: Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose
and throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a)
refrigerant. If accidental system discharge occurs, ventilate work area before resuming ser-
vice. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
e: Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam
parts. Damage may result.
PRECAUTIONS AND PREPARATIONMANUAL AND AUTO
HA-1

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 ®tting 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.
Failure 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 ®nal 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 portions 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 in¯ated portion of tube.
+After inserting tube into union until O-ring is no longer visible, tighten nut to speci®ed torque.
+After 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
connections of seal seat to the speci®ed torque.

HFC-134a (R-134a) Service Tools and
Equipment
Never mix HFC-134a refrigerant and/or its speci®ed lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for each type of refrigerant/lubricant.
Refrigerant container ®ttings, service hose ®ttings and service equipment ®ttings (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 ®tting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.

Precautions for Service Equipment
RECOVERY/RECYCLING EQUIPMENT
Follow the manufacturer's instructions for machine operation and
machine maintenance. Never introduce any refrigerant other than
that speci®ed into the machine.
ELECTRONIC LEAK DETECTOR
Follow the manufacture's instructions for tester operation and tester
maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the speci®ed lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric
pressure. 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 situated near the
hose-to-pump connection, as follows.
+Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
+For pumps without an isolator, use a hose equipped with a
manual shut-off valve near the pump end. Close the valve to
isolate the hose from the pump.
+If the hose has an automatic shut off valve, disconnect the hose
from the pump: 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 a 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 R-134a or 134a. Make
sure the gauge set has 1/2²-16 ACME threaded connections for
service hoses. Con®rm the set has been used only with refrigerant
HFC-134a (R-134a) along with speci®ed lubricant.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive
shut off devices (either manual or automatic) near the end of the
hoses opposite the manifold gauge.

Refrigeration Cycle
REFRIGERANT FLOW
The refrigerant ¯ow is in the standard pattern. Refrigerant ¯ows through the compressor, condenser, liquid
tank, evaporator and back to the compressor.
The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion
valve, located inside the evaporator case.
FREEZE PROTECTION
The compressor cycles on and off to maintain the evaporator temperature within a speci®ed range. When the
evaporator coil temperature falls below a speci®ed point, the thermo control ampli®er interrupts the compres-
sor operation. When the evaporator coil temperature rises above the speci®cation, the thermo control ampli-
®er allows compressor operation.
REFRIGERANT SYSTEM PROTECTION
Dual-pressure switch
The dual-pressure switch is located on the liquid tank. If the system pressure rises or falls out of specifications,
the switch opens to interrupt compressor clutch operation.
