Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001396449
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 SR and SB section of
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 inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001396428
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Working with HFC-134a (R-134a)INFOID:0000000001396429
WARNING:
 CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amounts. If the refrigerants are mixed a compressor mal-
function is likely to occur.
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If
oil other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil 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 connecting the components. Connect all refrigerant loop components as quickly as possible
to minimize the entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without
proper sealing, oil will become moisture saturated and should not be used.
- Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
- Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.

PRECAUTIONS
General Refrigerant Precaution
INFOID:0000000001396430
WARNING:
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
 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 (126° 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 suf-
focation.
 Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing 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 refrigerant manu-
facturers.
Oil PrecautionINFOID:0000000001396431
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil
other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil 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 oil from a sealed container. Immediately reseal containers of oil. Without proper seal-
ing, oil will become moisture saturated and should not be used.
 Avoid breathing A/C refrigerant and oil 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 service. Additional health and safety informa-
tion may be obtained from refrigerant and oil manufacturers.
 Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.

FEATURES OF NEW TYPE REFRIGERANT CONNECTION
 The 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 charac-
teristics.
 The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facili-
tating piping connections.

O-Ring Part Numbers and Specifications
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 vehicle.
Doing so will cause oil 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 con-
nection.
 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 the specified A/C oil to circle of the O-rings as shown. Be careful not to
apply oil to threaded portion.
 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.
 After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.

HFC-134a (R-134a) Service Tool and EquipmentINFOID:0000000001396437
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.
