Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL P11 is as follows (The
composition varies according to optional equipment):
lFor a frontal collision
The Supplemental Restraint System consists of driver's air bag module (located in the center of the
steering wheel), front passenger's air bag module (located on the instrument panel on passenger's side),
seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
lFor a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
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 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 RS section.
lDo 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 or tape 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:
lCFC-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.
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:
a: When removing refrigerant components from a vehicle, immediately cap (seal) the compo-
nent 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 specified 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. 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 equip-
ment). If accidental system discharge occurs, ventilate work area before resuming service.
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 or type R) to come in contact with sty-
rofoam parts. Damage may result.
PRECAUTIONS AND PREPARATION
HA-3

General Refrigerant Precautions
WARNING:
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 52ÉC (126ÉF).
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 introduce compressed air to any refrigerant container or refrigerant component.
Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
lExpansion valve to cooling unit.
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
lThe O-ring is relocated in a groove for proper installation. This eliminates the change 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 connecting 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
facilitating piping connections.

O-RING AND REFRIGERANT CONNECTION
CAUTION:
The new and former connections use different O-ring configurations. Do not confuse O-rings since
they are interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or around, the con-
nection.

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:
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
operation. Do not remove the seal caps of pipes and other components until just before connec-
tion.
lAllow components stored in cool areas to warm to ambient 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.

Part number: KLH00-PAGR0
Lubricant name: Nissan A/C System Oil Type S for compressor-model CSV613
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
connections of seal seat to the specified torque.

Precautions for Servicing Compressor
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 ªMaintenance of Lubricant Quantity in Compres-
sorº exactly. Refer to HA-102.
lKeep friction surfaces between clutch and pulley clean. If the surface is contaminated, with
lubricant, 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 compres-
sor is installed, let the engine idle and operate the compressor for one hour.
lAfter replacing the compressor magnet clutch, apply voltage to the new one and check for nor-
mal operation.

HFC-134a (R-134a) Service Tools and
Equipment
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cation oil.
Separate and non-interchangeable service equipment must be used for each type of refrigerant/lubricant.
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.

Precautions for Service Equipment
RECOVERY/RECYCLING/RECHARGING EQUIPMENT
Be certain to follow the manufacturer's instructions for machine
operation and machine maintenance. Never introduce any refrig-
erant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer's instructions for tester
operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compat-
ible with the specified lubricant for HFC-134a (R-134a) A/C sys-
tems. The vent side of the vacuum pump is exposed to atmo-
spheric 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 placed near the
hose-to-pump connection, as follows:
lUsually vacuum pumps have a manual isolator valve as part
of the pump. Close this valve to isolate the service hose from
the pump.
lFor 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.
lIf 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. Be sure
the gauge set has 1/2º-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 black stripe). All hoses must include positive
shut off devices (either manual or automatic) near the end of the
hoses opposite the manifold gauge.

SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers
to an CFC-12 (R-12) A/C system. The HFC-134a (R-134a) cou-
plers will 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
specified lubricants have been used with the scale. If the scale
controls refrigerant flow electronically, the hose fitting must be
1/2²-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may
be vented into air from cylinder's top valve when filling the cylin-
der with refrigerant. Also, the accuracy of the cylinder is gener-
ally less than that of an electronic scale or of quality recycle/
recharge equipment.
