Additional information on the following
items marked with an ``*'' is found in the
``Do-it- yourself'' section of this manual.
Emission control system
maintenance
Drive belts*Ð Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filterÐ Under normal driving
conditions, the air cleaner filter should be
replaced in accordance with the mainte-
nance schedule. However, driving the ve-
hicle in dusty areas may cause rapid clog-
ging of the element. Consequently, the
element may have to be replaced more
frequently.
Evap vapor linesÐ Check vapor lines and
connections for leaks, looseness or deterio-
ration. If leaks are found, replace them.
Fuel linesÐ Check the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any damaged parts.
Fuel filterÐ If the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, thefilter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Ð Drain and flush the
cooling system.
Engine oil & oil filter*Ð Under normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs*Ð Replace with new plugs
having the correct heat range.
Intake & exhaust valve clearanceÐ Check
the valve clearance if valve noise increases.
Chassis and body maintenance
Brake lines & cablesÐ Check the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, discs, drums & liningsÐ
Check these and the other neighboring brake
components for wear, deterioration and
leaks. Under severe driving conditions, they
may have to be inspected more frequently.
Manual & automatic transmission fluid*
Ð Check the fluid level and visually inspect
for signs of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft bootsÐ
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, inspection should be performed
more frequently
Exhaust systemÐ Visually check the ex-
haust pipes, muffler, and hangers for proper
attachment, leaks, cracks, chafing, abra-
sion, deterioration, etc. Under severe driv-
ing conditions, inspection should be per-
formed more frequently.
Supplemental air bag systemÐ Check
the supplemental air bag system compo-
nents for proper attachment, damage, de-
formities, cracks, rust, etc. Work around and
on the supplemental air bag system should
be done by an authorized NISSAN dealer.
EXPLANATION OF
MAINTENANCE ITEMS
9-10Maintenance
ZX

of at least 87 AKI (Anti-Knock Index) num-
ber. However, you may use unleaded gaso-
line with an octane rating as low as 85 AKI
(Anti-Knock Index) number in high altitude
areas [over 4,000 ft (1,219 m)] such as:
Colorado, Montana, New Mexico, Utah,
Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, 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 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 or overheating, which may
cause excessive fuel consumption or en-
gine damage. If any of the above symptomsare 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
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
