1996 NISSAN ALTIMA maintenance

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait a few minutes
for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean.
Reinsert it all the way.5. Remove the dipstick again and check the
oil level. It should be between the ``H''
and ``L'' marks. If the oil level is below the
``L'' mark, remove the oil filler cap and
pour recommended oil through the open-
ing.Do not overfill.
6. Recheck oil level with dipstick.
CAUTION
cOil level should be checked regu-
larly. Operating with insufficient
amount of oil can damage the en-
gine, and such damage is not cov-
ered by warranty.
cIt is normal to add some oil between
oil maintenance intervals or during
the break-in period, depending on
the severity of operating conditions.

WARNING
Be sure the ignition key is ``OFF''.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by your
NISSAN dealer.
2. Have the belts checked regularly for con-
dition and tension in accordance with the
maintenance schedule in this manual.WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the plugs. An incorrect socket
can cause damage.1. Remove brackets as necessary to give
access to the high tension spark plug
cables and spark plugs.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.

3. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that each
spark plug is snugly fitted into the plug
socket.
4. Check the gap on each new spark plug
with a feeler gauge.Use only the speci-
fied spark plugs.The spark plug gap is
shown in the ``Technical and consumer
information'' section. Adjust it as re-
quired.5. Fit the new plugs, one at a time, into the
spark plug socket and install them. Turn
each plug several full turns by hand, then
tighten with a spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 Nzm)
6. Holding the boot, reconnect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.
7. Reinstall all brackets as necessary.
The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the ``Main-
tenance schedule'' section. When replacing
the filter, wipe the inside of the air cleaner
filter housing and the cover with a damp
cloth.

With the engine running, check the distance
between the upper surface of the pedal and
the metal floor. If it is out of the range shown
above, see your NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.The front (and rear, if equipped) disc-type
brakes self-adjust every time the brake
pedal is applied. The rear drum- type brakes
also self-adjust every time the brake pedal
is applied.
If the brake pedal goes down farther than
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 will make 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 brakenoise 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 from
the 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.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
that the specified maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance care. You are a
vital link in the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these procedures regularly as pre-
scribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, your NISSAN dealer.
Periodic maintenance
The maintenance items listed in this part are
required to be serviced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance
will be required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN's vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.
You can be confident that your NISSAN
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicle Ð in a reliable and
economic way.
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations
or smells, be sure to check for the cause or
have your NISSAN dealer do it promptly. In
addition, you should notify your NISSAN
dealer if you think that repairs are required.
When performing any checks or mainte-
nance work, closely observe the precautions
in the ``Do-it-yourself operations'' section.
OUTSIDE THE VEHICLE
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Additional information on the items
marked with ``*'' can be found in the
``Do-it- yourself operations'' section.
Tires*Ð Check the pressure with a gauge
periodically when at a service station, in-
cluding the spare, and adjust to the speci-
fied pressure if necessary. Check carefully

Tire rotation*Ð Tires should be rotated
every 7,500 miles (12,000 km).
Wheel alignment and balanceÐIfthe
vehicle should pull to either side while driv-
ing 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*Ð Check for
cracks or wear if they do not wipe properly.
Doors and engine hoodÐ Check that all
doors and the engine hood operate prop-
erly. Also ensure 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 lubrication
frequently.
Lights*Ð 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

that the wipers and washer operate properly
and that the wipers do not streak.
Windshield defrosterÐ Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelÐ Check for changes in
the steering conditions, such as excessive
freeplay, hard steering or strange noises.
SeatsÐ Check seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and that the locks (if so
equipped) hold securely in all latched posi-
tions.Seat beltsÐ Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Accelerator pedalÐ Check 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*Ð Make sure the pedal
operates smoothly and check that it has the
proper free travel.
BrakesÐ Check that the brakes do not pull
the vehicle to one side when applied.

UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the items
marked with ª*º can be found in the
ªDo-It-Yourself operationsº section.
Windshield washer fluid*Ð Check that
there is adequate fluid in the tank.
Engine coolant level*Ð Check the cool-
ant level when the engine is cold.
Radiator and hosesÐ Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Brake and clutch fluid levels*Ð Make
sure that the brake and clutch fluid level is
between the ``MAX'' and ``MIN'' lines on the
reservoir.Battery*Ð Check the fluid level in each
cell. It should be between the ``MAX'' and
``MIN'' lines.
Engine drive belts*Ð Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*Ð Check the level after
parking the vehicle on a level spot and
turning off the engine.
Power steering fluid level* and linesÐ
Check the level when the fluid is cold and
the engine is turned off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level*Ð
Check the level after putting the shift lever in
``P'' with the engine idling.
Exhaust systemÐ Make sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section.)
UnderbodyÐ The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. Itis very important to remove these sub-
stances, otherwise rust will form on the floor
pan, frame, fuel lines and around the ex-
haust 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 may accu-
mulate. See the ``Appearance and interior
care'' section for additional information.
Fluid leaksÐ Check 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 if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
