Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS004YA
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.
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 per-
formed by an authorized NISSAN/INFINITI 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 SRS 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
harness connectors.
Precautions for Working with HFC-134a (R-134a)EJS000T1
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 amount. If the refrigerants are mixed and compressor
malfunction is likely to occur.
Use 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 malfunction is likely to occur.
The 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-
ble to minimize the entry of moisture into system.
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. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refriger-
ant. If accidental system discharge occurs, ventilate work area before resuming service. Addi-
tional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
Do not allow lubricant (Nissan A/C System Oil Type S or R) to come in contact with styrofoam
parts. Damage may result.

General Refrigerant PrecautionsEJS000T2
WARNING:
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 (125°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
suffocation.
Do 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 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 refriger-
ant manufacturers.
Lubricant PrecautionsEJS0027Y
Use 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 malfunction is likely to occur.
The 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.
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 acciden-
tal 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 or R) to come in contact with styrofoam parts. Dam-
age may result.
Precautions for Refrigerant ConnectionEJS000T4
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
Expansion valve to cooling unit
Refrigerant pressure sensor to liquid tank
ATC-8
PRECAUTIONS
With Diesel Engine
NOTE:
This illustration is for RHD models. The blower and heater & cooling unit layouts for LHD models are symmet-
rically opposite.
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
O-Ring Part Numbers and Specifications
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.
