• When CONSULT-III is connected with a data link connectorequipped on the vehicle side, it will communicate with the control
unit equipped in the vehicle and then enable various kinds of diag-
nostic tests.
• Refer to “CONSULT-III Operation Manual” for more information.

General Refrigerant PrecautionINFOID:0000000005147633
WARNING:
• Do not release refrigerant into the air. Use appr oved recovery/recycling equipment to capture the
refrigerant every time an air co nditioning 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 containe r 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: poison ous 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.
Precaution for Leak Detection DyeINFOID:0000000005147634
• The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjuncti on with an electronic refrigerant leak detector (J-
41995).
• For your safety and the customer's satisfaction, read and follow all manufacturer's operating instructions and precautions prior to performing work.
• A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should
only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).
• Always remove any dye from the leak area after repairs are complete to avoid a misdiagnosis during a future service.
• Do not allow dye to come into contact with paint ed body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of
time cannot be removed.
• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not use more than one refrigerant dye bot tle (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. Do not use HFC-
134a (R-134a) leak detection dye in CFC-12 (R-12) A/ C systems or CFC-12 (R-12) leak detection dye in
HFC-134a (R-134a) A/C systems or A/C system damage may result.
• The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure occurs.
A/C Identification LabelINFOID:0000000005147635
Vehicles with factory installed fluorescent dye have this identification label on the underside of hood.
Precaution for Refrigerant ConnectionINFOID:0000000005147636
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
• Expansion valve to cooling unit
• Evaporator pipes to evaporator (inside cooling unit)
• Refrigerant pressure sensor
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
• The O-ring has been relocated. It has also been provided with a groove for proper installation. This reduces the possibility 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 character-
istics.

GENERAL MAINTENANCE
General MaintenanceINFOID:0000000005145933
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owner can perform these
checks and inspections or have thei r INFINITI dealers perform them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed fr om time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.
Item Reference page
Tires Check the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear. WT-47, "
Inspection"
Wheel lug nuts
When checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary. WT-49, "Rotation"
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. GW-11, "Removal and
Installation"
Tire rotation
Tires should be rotated every 12,000 km (7,500 miles). WT-49, "Rotation"
Tire Pressure Monitor-
ing System (TPMS)
transmitter componentsReplace the TPMS transmitter grommet seat, valve core and cap when the tires
are replaced due to wear or age.
WT-50, "Transmitter
(Pressure Sensor)"
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel bal-
ancing may be needed. WT-48, "Balancing
Wheels", FSU-6, "Front
Wheel Alignment"
Windshield wiper
blades
Check for cracks or wear if they do not wipe properly.
—
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the back
door. Also make sure that all latches lock securely. Lubricate if necessary. Make
sure that the secondary latch keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently. MA-38, "

Lamps
Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head
lamp aim. Clean the head lamps on a regular basis. EXL-145, "HEADLAMP :
