HFC-134a (R-134a) Service Tools and
Equipment
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cation oil.
Separate and non-interchangeable service equipment must be used for 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 CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.

PRECAUTIONS AND PREPARATION
HA-8

Maintenance of Lubricant Quantity in
Compressor
The lubricant used to lubricate the compressor circulates through
the system with the refrigerant. Add lubricant to compressor
when replacing any component or after a large gas leakage
occurred. It is important to maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
lLack of lubricant: May lead to a seized compressor
lExcessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANT
Name: Nissan A/C System Oil Type R
Part number: KLH00-PAGR0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the flowchart shown
below.
START
Can lubricant return operation be per-
formed?
lA/C system works properly.lThere is no evidence of a large amount of
lubricant leakage.
No
cYes
Perform lubricant return operation, proceeding as follows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Start engine, and set the following conditions:
lTest condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is
25 to 30ÉC (77 to 86ÉF).]
2. Next item is for V-5 or V-6 compressor. Connect the manifold
gauge, and check that the high pressure side pressure is 588 kPa
(5.9 bar, 6 kg/cm
2, 85 psi) or higher.
If less than the reference level, attach a cover to the front face of
the condenser to raise the pressure.
3. Perform lubricant return operation for about 10 minutes.
4. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant
return operation.
Should the compressor be replaced?
No Yes
b
VA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount of
lubricant leakage.)
No
cYes
After replacing any of the following major components, add the correct
amount of lubricant to the system.
Amount of lubricant to be added
*1: If compressor is replaced, addition of lubricant is included in the flow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

SERVICE PROCEDURES
HA-50

General maintenance includes those items which should be checked during the normal day-to-day opera-
tion of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can per-
form the checks and inspections themselves or they can have their NISSAN dealers do them.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
specified.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the specified pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, rollers and
links 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 for lubrication fre-
quently.MA-39
Tire rotationTires should be rotated every 10,000 km (6,000 miles) for 2WD models and every
5,000 km (3,000 miles) for 4WD models.MA-35
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle, etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear or damage.MA-40
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer fluidCheck that there is adequate fluid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-16, 25
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-19, 24
Brake and clutch fluid levelMake sure that the brake and clutch fluid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-32, 35
BatteryCheck the fluid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð
