< PRECAUTION >
PRECAUTIONS
 Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes equall y lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.
 Apply voltage to the new one and check for norma l operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
 The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leakages.
 Wear always fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye.
 The fluorescent dye leak detector is not a replacem ent for an electrical leak detector. The fluorescent
dye leak detector should be used in conjunction with an electrical leak detector to pin-point refriger-
ant leakages.
 Read and follow all manufacture’ s operating instructions and precau tions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
 A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after conf irming the leakage with an electrical leak detector.
 Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a future service.
 Never allow dye to come into contact with painted body panels or interior components. Clean imme-
diately with the approved dye cl eaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
 Never spray the fluorescent dye cleaning agent on hot surfaces (eng ine exhaust manifold, etc.).
 Never use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
 Leak detection dyes for HFC-134a (R-134a) and CFC- 12 (R-12) A/C systems are different. Never use
HFC-134a (R-134a) leak detection dye in CFC-12 (R- 12) A/C system, or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, or A/C system damage may result.
 The fluorescent properties of the dye remains fo r three or more years unless a compressor malfunc-
tion occurs.
NOTE:
Identification
 Vehicles with factory installed fluorescent dye have a green label.
 Vehicles without factory installed fluorescent dye have a blue label.

RECOVERY/RECYCLING RECHARGING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer’s instruct ions for tester operation and tester maintenance.

HFC-134a (R-134a) Service Tool and Equipment
 Never mix HFC-134a (R-134a) refrigerant and/or its s pecified lubricant with CFC-12 (R-12) refrigerant and/
or its lubricant.
 Separate and non-interchangeable service equipment must be used for handling 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 CF C-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
 Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and
compressor malfunction may result.

f found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genu ine NISSAN Long Life Antifreeze/Coo lant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are

transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited wa rranty.
*3: DEXRON™ VI type ATF may also be used.
*4: Available in mainland U.S.A. through an INFINITI dealer.
*5: Using transfer fluid other t han Genuine NISSAN Transfer Fluid will damage the transfer , which is not covered by the INFINITI new
vehicle limited warranty. See an INFINITI retailer for recommended transfer fluid.
*6: For hot climates, Viscosity SAE 90 is suitable for ambient temperatures above 0 °C (32 °F)
*7: See an INFINITI dealer for service for synthetic oil.
*8: Using Hydraulic Suspen sion fluid other than Genuine NISSAN Hydraulic Susp ension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspensio n fluid.
*9: The fluid capacity is the reference value.
Engine Oil RecommendationINFOID:0000000006287732
NISSAN recommends the use of an energy conservi ng oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) ce rtification and SAE viscosity standard. These oils
have the API certification mark on t he front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

Anti-Freeze Coolant Mixture RatioINFOID:0000000006287733
The engine cooling system is filled at the factory with
a high-quality, year-round, anti-freeze coolant solution.
The anti-freeze solution contains rust and corrosion inhi bitors. Therefore, additional cooling system additives
are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Antifreeze/Coolant
(blue) or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized or distilled
water.
Mixing any other type of coolant or the use of non- distilled water will reduce the life expectancy of the
factory-fill coolant.
