1997 NISSAN ALTIMA Owners 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 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.

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.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 backfires, you could be
burned. Don't drive with it off, and be
careful working on the engine with the
air cleaner off.

CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chat-
ters when running, wax or other material
may be on the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form
when rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water.
If your windshield is still not clear aftercleaning the blades and using the wiper,
replace the blades.
REPLACEMENT
1. Pull the wiper arm away from the wind-
shield.
2. Push the tab, then move the wiper blade
down.
3. Insert the new wiper blade onto the wiper
arm until a clicking sound is heard.
CAUTION
cAfter wiper blade replacement, re-
turn the wiper arm to its original
position.
cOtherwise it may be damaged when
the engine hood is opened.
cMake sure the wiper blade contacts
the glass; otherwise the arm may be
damaged from wind pressure.

If you wax the surface of the hood, be
careful not to let wax get into the washer
nozzle. This may cause clogging or im-
proper windshield washer operation. If wax
gets into the nozzle, remove it with a needle
or small pin.From the released position, pull the parking
brake lever up slowly and firmly. If the
number of clicks is out of the range listed
above, see your NISSAN dealer.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.ADI0613

PARKING BRAKE CHECK BRAKE PEDAL

ZX

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 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 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.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. Keep 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.
