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 the 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.

Platinum-tipped spark plug
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because 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 ``Mainte-
nance'' section of this manual. When replac-
ing 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 back-
fires. If it isn't in place, and the engine
backfires, you could be burned. Do not
drive with it off, and be careful working
on the engine with the air cleaner off.

normal, it may be due to a lack of adjust-
ment of the rear drum brakes. To adjust
apply the parking brake several times.
WARNING
See an authorized 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 an authorized NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance'' 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 an
authorized NISSAN dealer.

To ensure smooth, trouble-free, safe and
economical driving, NISSAN provides two
periodic maintenance schedules that may be
used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals, up
to 60,000 miles (96,000 km)/48 months. For
most people, the odometer reading indicates
when service is needed. However, if you
drive very little, your vehicle should be ser-
viced at the regular time intervals shown in
the schedules.After 60,000 miles (96,000
km)/48 months, continue periodic mainte-
nance at the same mileage/time intervals.
SCHEDULE ONE
Follow Periodic Maintenance Schedule one
if your driving habits frequently include one
or more of the following driving conditions:
cRepeated short trips of less than 5
miles (8 km).
cRepeated short trips of less than 10
miles (16 km) with outside tempera-
tures below freezing.
cOperating the vehicle in hot weather
during stop-and-go ``rush hour'' traf-
fic.cExtensive idling and/or low speed
driving for long distances, such as
police, taxi or door-to-door delivery
use.
cDriving in dusty conditions.
cDriving on rough, muddy, or salt
spread roads.
cTowing a trailer, using a camper or a
car-top carrier.

(3) If vehicle is operated under extremely adverse weather conditions or in areas where ambient temperatures are either extremely low or extremely
high, the filters might become clogged. In such an event, replace them immediately.
