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.

they are interchangeable. If a wrong O-ring is installed, re

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.
Lubricant name: Nissan A/C System Oil Type R for compressor-model CR-14
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.
