Engine Coolant Mixture Ratio
ELS001JC
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality engine
coolant contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:
lWhen adding or replacing coolant, be sure to use only Gen-
uine NISSAN Anti-freeze Coolant (L250) or equivalent in its
quality. Because L250 is premixed type coolant.
The use of other types of engine coolant may damage your
cooling system.
lWhen checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant
temperature.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS005QE
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:
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/INFINITI 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 SRS section.
lDo 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)EJS00627
WARNING:
lCFC-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 and compressor
malfunction is likely occur.
lUse 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.
lThe 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) to come in contact with styrofoam parts.
Damage may result.
Contaminated RefrigerantEJS0063C
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
lExplain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.
lExplain that recovery of the contaminated refrigerant could damage your service equipment and refriger-
ant supply.
lSuggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
lIf you choose to perform the repair, recover the refrigerant using onlydedicated equipment and contain-
ers. Do not recover contaminated refrigerant into your existing service equipment.If your facility
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for avail-
able service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.

General Refrigerant PrecautionsEJS00628
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 52°C.
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 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.
Precautions for Refrigerant ConnectionEJS005FL
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
lExpansion valve to cooling unit
lEvaporator pipes to evaporator (inside cooling unit)
lRefrigerant pressure sensor
ABOUT ONE-TOUCH JOINT
Description
lOne-touch joints are pipe joints which do not require tools during piping connection.
lUnlike conventional connection methods using union nuts and flanges, controlling tightening torque at
connection point is not necessary.
lWhen removing a pipe joint, use a disconnector.
