When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the gearshift
control lever to Neutral (N).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cBe sure to turn the ignition key to the
OFF or LOCK position.
When the ignition key is in the ON or
ACC position, the cooling fan may
start to operate suddenly even when
the engine is not running.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cNever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition is
on.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
cFailure to follow these or other com-
mon sense guidelines may lead to
serious injury or vehicle damage.cImproperly disposed motor oil and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid. Avoid contact with used motor
oil.
This ``Do-it-yourself operations'' section
gives instructions regarding only those
items which are relatively easy for an owner
to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by your NISSAN dealer.

6. Recheck oil level with dipstick.
CAUTION
cOil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered 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.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature, and then turn it off.
3. Place a large drain pan under the drain
plug.
4. Remove the oil filler cap.
5. Remove the drain plug with a wrench and
completely drain the oil.If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing engine oil filter'' in this section.
WARNING
cProlonged and repeated contact with
used engine oil may cause skin
cancer.
cTry to avoid direct skin contact with
used oil. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep used engine oil out of reach of
children.

WARNING
Be careful not to burn yourself, as the
engine oil is hot.
CAUTION
cWaste oil must be disposed of prop-
erly. Check your local regulations.
cAvoid direct contact with used en-
gine oil.
6. Clean and re-install the drain plug and
washer. Securely tighten the drain plug
with a wrench.Drain plug tightening torque:
22 to 29 ft-lb
(29 to 39 N²m)
Do not overtighten.
7. Refill engine with recommended oil and
install the cap securely.
See the ``Technical and consumer infor-
mation'' section for refill capacity.
8. Start the engine.
Check for leakage around the drain plug
and oil filter. Correct as required.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3.
Loosen the oil filter with an oil filter wrench.
(Depending on the engine model, a special
cap typewrench may be required. See
your NISSAN dealer if in doubt.) Remove
the oil filter by turning it by hand.
WARNING
Be careful not to burn yourself, as the
engine oil may be hot.

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.

5. Fit the new plugs, one at a time, into the
spark plug socket and install them. Turn
each plug in 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 N²m)
6. Holding the boot, re-connect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.
7. Re-install all brackets as necessary.
SR20DE Engine
Platinum-tipped spark plug
It is not necessary to replace the platinum-
tipped spark plugs as frequently as the
conventional type spark plugs since they
last much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping. Blue rings on the
ceramic portion indicate that the plugs are
platinum-tipped.
cAlways replace spark plugs with rec-
ommended or equivalent ones.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
housing and the cover with a damp cloth.
WARNING
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame if the engine
backfires. If it isn't there, and the engine back-
fires, you could be burned. Don't drive with it off,
and be careful working on the engine with the air
cleaner off.
