cKeep your engine tuned up.
cFollow the recommended periodic main-
tenance schedule.
cKeep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
cKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
cWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
c
Use 4H or 4L position only when neces-
sary. Four-wheel drive operation lowers
fuel economy.
TRANSFER CASE SHIFTING
PROCEDURES
CAUTION
Do not drive on dry hard surface roads
in four-wheel drive. Driving on dry hard
surfaces in 4H or 4L may cause unnec-
essary noise, tire wear, and increased
fuel consumption. NISSAN recom-
mends driving in the 2H position under
these conditions.
WARNING
cWhen parking the vehicle, apply the
parking brake and always make sure
to shift the transfer control lever into
the 2H, 4H or 4L position.
cDo not leave the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-
pectedly even if the manual
transmission is in gear or the auto-
matic transmission is in the P (Park)
position.
cFailure to engage the transfer con-
trol lever in 2H, 4H, or 4L could result
in the vehicle moving unexpectedly,

USING FOUR-WHEEL DRIVE
5-20Starting and driving
ZX
If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain
active solvents or similar ingredients that
can be harmful to the fuel system and
engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 (except supercharger) or 91
(supercharger) AKI (Anti-Knock Index).
However, for non-supercharged vehicles
only, you may use unleaded gasoline with
an octane rating as low as 85 AKI in high
altitude areas (over 4,000 ft [1,219 m]) suchas: 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
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not re-
sponsible.
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.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This isno cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
