lWhen checking sunload sensor, select a place where
sun shines directly on it.
A/C RELAY
The A/C relay is located on the left side of the engine room.
When the A/C remain and fan switch are ON, the A/C relay
operates and transmits A/C operation signals to ECM.
Control System Auto Amplifier (Auto amp.)
The auto amplifier has a built-in microcomputer which processes
the information sent from the various sensors needed for air
conditioner operation. The air mix door motor and blower motor
are then controlled.
Signals from the various switches and the Potentio Temperature
Control (PTC) are directly entered into the auto amplifier.
SUNLOAD INPUT PROCESS
The auto amp. also includes a processing circuit which ªaver-
agesº the variations in detected sunload over a period of time.
This prevents drastic swings in the ATC system operation due to
small or quick variations in detected sunload.
For example, consider driving along a road bordered by an occa-
sional group of large trees. The sunload detected by the sunload
sensor will vary whenever the trees obstruct the sunlight. The
processing circuit averages the detected sunload over a period
of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC

PRE-DELIVERY INSPECTION ITEMS
MA-4

General maintenance includes those items which should be checked during normal day-to-day operation of
the vehicle. They are essential if the vehicle is to continue functioning correctly. Owners can perform the
checks and inspections themselves, or they can be carried out by a NISSAN dealer.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
TiresCheck the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or exces-
sive wear.
Windshield wiper bladesCheck for cracks or wear if not functioning correctly.
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
function correctly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch prevents the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication more
often.MA-54
Tire rotationTires should be rotated every 10,000 km (6,000 miles). MA-53
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 correctly and installed securely. Also check headlight aim.
Warning lights and buzzers/chimesMake sure that all warning lights and buzzers/chimes
are functioning correctly.
Steering wheelCheck that it has the specified play. Check for changes in the steering
operation, such as excessive free play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in.)
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-54
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.
Engine coolant levelCheck the coolant level when the engine is cold.
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-24 / MA-34 /
MA-45
Brake and clutch fluid levelsMake sure that the brake and clutch fluid levels are between
the“MAX”and“MIN”lines on the reservoir.MA-51 / MA-48
BatteryCheck the fluid level in each cell. It should be between the“MAX”and“MIN”lines.

Checking and Adjusting Drive Belts
Refer to section MA for Drive Belt Inspection.
Checking Fluid Level
Check fluid level.
Fluid level should be checked using ªHOTº range on dipstick at
fluid temperatures of 50 to 80ÉC (122 to 176ÉF) or using ªCOLDº
range on dipstick at fluid temperatures of 0 to 30ÉC (32 to 86ÉF).
CAUTION:
lDo not overfill.
lRecommended fluid is Automatic Transmission Fluid
ªDEXRONTMº type.
Checking Fluid Leakage
Check the lines for security, leaks, cracks, damage, loose
connections, chafing or deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds
and carefully check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
4. If fluid leakage at connectors is noticed, loosen flare nut and
then retighten.
Do not overtighten connector as this can damage O-ring,
washer and connector.
5. Check rack boots for accumulation of power steering fluid.
Bleeding Hydraulic System
1. Raise front end of vehicle until wheels are clear of the
ground.
2. Add fluid into oil tank to specified level. Then quickly turn
steering wheel fully to right and left and lightly touch steer-
ing stoppers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2 above.
