1997 NISSAN ALTIMA brake

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.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the shift lever to P (Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cYour vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.cIf you must work with the engine
running, 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
enclosed 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
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and the
battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, 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.
CAUTION
cDo not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.
cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is ON.
cNever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition is on.
c
Avoid contact with used engine oil.
Improperly disposed motor oil and/or
other vehicle fluids can hurt the en-
vironment. Always conform to local
regulations for disposal of vehicle
fluid.
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.

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 opening.
Do not overfill.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
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.

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 it does not fall
when it is pulled out. Make sure 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.
