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.

Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see an authorized NISSAN dealer.CAUTION
Never use a fuse of higher amperage
rating than that specified on the fuse
box cover. This could damage the elec-
trical system or cause a fire.
Engine compartment
If the electrical equipment does not come
on, check for an open fuse.
1. Be sure the ignition switch and the head-
light switch are OFF.
2. Open the engine hood.3. Remove the fuse box cover.
4. Remove the fuse with the fuse puller
located on the reverse side of the pas-
senger compartment fuse box cover.
5. If the fuse is open, replace it with a new
fuse.
6. If a new fuse also opens, have the elec-
trical system checked and repaired by an
authorized NISSAN dealer.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace with only genuine NISSAN
parts.ADI0654ADI0628

of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern Idaho, western
South Dakota, western Nebraska, and the
part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady
speed on level roads, have an authorized
NISSAN dealer correct the condition.
Failure to correct the condition is misuse
of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-toms are encountered, have your vehicle
checked at an authorized NISSAN dealer or
other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
not a cause for concern, because you
get the greatest fuel benefit when there
is light spark knock for a short time
under heavy engine load.
