4. Wipe the engine oil filter mounting sur-
face with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine.
5. Coat the rubber gasket on the new filter
with clean engine oil.
6. Screw in the oil filter until a slight resis-
tance is felt, then tighten an additional
2/3 turn.
7. Start the engine and check for leakage
around the oil filter. Correct as required.8. Turn the engine off and wait several
minutes. Check the oil level. Add engine
oil if necessary.WARNING
cWhen engine is running, keep hands
and clothing away from any moving
parts such as cooling fan and drive
belts.
cAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.

normal, it may be due to a lack of adjust-
ment of the rear drum brakes. Apply the
parking brake several times.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise fromthe rear drum brakes, have them inspected
as soon as possible by your NISSAN
dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.Check the brake booster function as fol-
lows:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to the
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, see
your NISSAN dealer.

Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see your NISSAN dealer.Engine compartment (Headlight
fuses)
If a headlight does not come on, check for
an open fuse.
1. Be sure the ignition key and the headlight
switch are OFF.
2. Open the engine hood.
3. Remove the fuse box cover.
4. Remove the fuse with the fuse puller
provided (inside the passenger compart-
ment fuse panel cover).5. If the fuse is open, replace it with a new
fuse.
Never use a fuse of higher amperage
rating than that specified on the fuse box
cover.
6. If a new fuse opens again, have the
electrical system checked and repaired
by your NISSAN dealer.
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine NISSAN
parts.

Tire rotation*Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balanceIf the ve-
hicle should pull 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 alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Check for
cracks or wear if they do not wipe properly.
Doors and engine hoodCheck that all
doors and the engine hood operate prop-
erly. Also ensure that all latches lock se-
curely. Lubricate hinges, latches, rollers and
links if necessary. Make sure 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 lubrication
frequently.
Lights*Make sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.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.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Warning lights and chimesMake sure all
warning lights and chimes are operating
properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelCheck for changes in the
steering conditions, such as excessive free-
play, hard steering or strange noises.
SeatsCheck seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up anddown smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck that all parts of the seat
belt system (e.g. buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedalCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mats away from the pedal.
Clutch pedal*Make sure the pedal oper-
ates smoothly and check that it has the
proper free travel.
BrakesCheck that the brakes do not pull
the vehicle to one side when applied.
Brake pedal*Check the pedal for smooth
operation and make sure it has the proper
distance under it when depressed fully.
Check the brake booster function. Be cer-
tain to keep floor mats away from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill

an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern Idaho, western
South Dakota, western Nebraska, and that
part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady
speed on level roads, have your dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing results in knocking,
after-run and/or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked at a NISSAN dealer or other
competent service facility.However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
