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).
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Keep the floor
mats away from the pedal.BR-5, "
Inspection and
Adjustment", BR-15,
"On-Vehicle Service"
Parking brakeCheck that the parking brake control has the proper travel and make sure that
the vehicle is held securely on a fairly steep hill when only the parking brake is
applied.PB-4
Automatic transmis-
sion “Park” mecha-
nismOn a fairly steep hill check that the vehicle is held securely with the selector lever
in the P position without applying the brakes. — ItemReference page
ItemReference page
Windshield washer
fluidCheck that there is adequate fluid in the tank.
—
Engine coolant levelCheck the coolant level when the engine is cold. —
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation, de-
terioration or loose connections.—
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoirsMA-27
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require fre-
quent checks of the battery fluid level.—
Engine drive beltMake sure that no belt is frayed, worn, cracked or oily.MA-12
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turn-
ing off the engine.—
Power steering fluid
level and linesCheck the level on the reservoir with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.MA-28
Automatic transmis-
sion fluid levelCheck the level on the dipstick after putting the selector lever in “P” with the en-
gine idling.MA-21
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.MA-21
UnderbodyThe underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately.—

2. Disconnect the harness connector, then remove the air cleaner case (upper).
3. Remove the air cleaner filter from the air cleaner case (lower).
4. Install the new air cleaner filter in the air cleaner case (lower).
5. Install the air cleaner case (upper) and connect the harness connector.
6. Install the air duct and resonator assembly.
Changing Engine OilINFOID:0000000003533871
WARNING:
• Be careful not to burn yourself, as the engine and engine oil are hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin
contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil drain plug in the oil pan.
CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on the oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using the dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec-
essary and install the oil filler cap.
CAUTION:
Do not overfill the engine with oil.

POWER STEERING FLUID
POWER STEERING FLUID
Checking Fluid LevelINFOID:0000000003532821
Check power steering fluid level with engine off, referring to the scale
on reservoir tank.
Use HOT range for fluid temperatures of 50° – 80°C (122° – 176°F).
Use COLD range for fluid temperatures of 0° – 30°C (32° – 86°F).
CAUTION:
• Do not overfill.
• Do not reuse any used power steering fluid.
• Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-10
.
Checking Fluid LeakageINFOID:0000000003532822
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50° – 80°C (122° –
176°F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to
check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-21
.
6. Check steering gear boots for accumulation of fluid indicating a leak from the steering gear.
Air Bleeding Hydraulic SystemINFOID:0000000003532823
Incomplete air bleeding causes the following. When this happens, bleed air again.
• Air bubbles in reservoir tank.
• Clicking noise in oil pump.
• Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from oil
pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds.
Then check for fluid leakage.
3. Repeat step 2 several times at about three second intervals.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that oil pump may be damaged.)
4. Check for air bubbles or cloudy fluid.
5. If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloud-
iness does not exist.
6. Stop engine, check fluid level.

Component Parts and Harness Connector LocationINFOID:0000000003533551
System DescriptionINFOID:0000000003533552
• Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).
• The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by the BCM when the wiper switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R (intelligent power distribution module engine room) operates the wiper motor according to CAN
communication signals from the BCM.
Power is supplied at all times
• through 50A fusible link (letter f, located in the fuse and fusible link box)
• to BCM terminal 70, and
• through 30A fuse (No. 39, located in the IPDM E/R)
• to front wiper relay (located in the IPDM E/R).
With the ignition switch in ON or START position, power is supplied
• through 10A fuse (No. 9, located in the fuse block J/B)
• to combination switch terminal 14, and
• through 10A fuse (No. 59 located in the fuse and relay box)
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67 and
• to combination switch terminal 12
• through grounds M57, M61 and M79, and
• to IPDM E/R terminals 38 and 59 and
• to front wiper motor terminal 1
• through grounds E9, E15, and E24.
