Overdrive switch (KA24DE engine
type b)
Each time your vehicle is started, the trans-
mission is automatically ``reset'' to overdrive
ON.
ON: For normal driving the overdrive
switch is engaged. The transmission
is upshifted into overdrive as the
vehicle speed increases.
The overdrive does not engage until the
engine has reached operating tempera-
ture.OFF: For driving up and down long slopes
where engine braking is necessary,
push the overdrive switch once. The
O/D OFF indicator light illuminates at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable
shift shocks as the transmission shifts be-
tween 3rd gear and overdrive repeatedly. In
this case, press the overdrive switch.
When driving conditions change, press the
overdrive switch to turn the overdrive on.
The O/D OFF indicator light goes out.
Remember not to drive at high speeds for
extended periods of time with the O/D OFF
light illuminated. This reduces the fuel
economy.
Overdrive switch (VG33E or
VG33ER engines)
ON: With the engine running and the se-
lector lever in the D (Drive) position,
the transmission upshifts into OVER-
DRIVE as vehicle speed increases.
OVERDRIVE does not engage until the
engine has reached operating tempera-
ture.
OFF: For driving up and down long slopes
where engine braking is necessary
push the OVERDRIVE switch once.

WARNING
cDo not downshift abruptly on slip-
pery roads. This may cause a loss of
control.cDo not over-rev the engine when
shifting to a lower gear. This may
cause a loss of control or engine
damage.
CAUTION
cDo not rest your foot on the clutch
pedal while driving. This may cause
clutch damage.
cStop your vehicle completely before
shifting into R (Reverse).
cWhen the vehicle is stopped with the
engine running (for example at a
stop light), shift to N (Neutral) and
release the clutch pedal with the foot
brake applied.
Shifting
To change gears, or when upshifting or
downshifting, depress the clutch pedal fully,
shift into the appropriate gear, then release
the clutch slowly and smoothly.
You cannot shift directly from 5th gear into
R (Reverse). First shift into the N (Neutral)
position, then into R (Reverse).
If it is difficult to move the shift lever into R
(Reverse) or 1st, shift into N (Neutral), then
release the clutch pedal. Depress the clutch
pedal and shift into R (Reverse) or 1st
again.

WARNING
cBe sure the parking brake is fully
released before driving. Failure to do
so can cause brake failure and lead
to an accident.
cDo not release the parking brake
from outside the vehicle.
cDo not use the gear shift in place of
the parking brake. When parking, be
sure the parking brake is fully en-
gaged.
c
Do not leave children unattended in a
vehicle. They could release the park-
ing brake and cause an accident.

cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelera-
tor position.
cDrive at moderate speeds on the high-
way. Driving at high speeds lowers fuel
economy.
cAvoid unnecessary stopping and brak-
ing. Maintain a safe distance behind
other vehicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.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,resulting in serious personal injury
or property damage.
2HÐ (2WD, high range) Only the rear
wheels are driven. Use for driving under the
same conditions as standard 2WD vehicles
or state dynamometer I/M testing.
4HÐ (4WD, high range) Four wheels are
driven. Use when driving on roads where it
is difficult to drive in the 2H position (i.e.,
driving at normal speeds on snow covered,
icy, wet, muddy or sandy roads).
4LÐ (4WD, low range) Four wheels are
driven. Use when climbing or descending
steep hills, or during hard driving in sand,
mud or deep snow. The 4L position pro-
vides maximum power and traction. Avoid
raising vehicle speed excessively, as the
maximum speed is approximately 30 MPH
(48 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position.
Shift the lever quickly and smoothly when
moving across the N (Neutral) position with
the vehicle stopped.
AUTO-LOCK FREE-
RUNNING HUBS
The auto-lock free-running hub is designed
to allow for automatic four-wheel drive en-
gagement when the shift lever is moved to
the 4H or 4L position. If your vehicle is
equipped with this system, follow these op-
erational cautions:
CAUTION
cThe auto-locking hubs will make a
clicking noise when engaging and
disengaging. This is normal.

TO SHIFT
TRANSFER CASE:SHIFT PROCEDURE FOR AUTO-LOCK FREE-RUNNING HUBS
From 2H to 4HMove the transfer case shift lever to 4H at speeds below 25 MPH (40 km/h). It is not necessary to depress the clutch pedal. Per-
form this operation when driving straight, not while cornering.
From 4H to 2H1. Move the transfer case shift lever to 2H. This can be done at any speed, and it is not necessary to depress the clutch pedal.
Perform this operation when driving straight, not while cornering.
2. Disengage the AUTO-LOCK hubs following the procedure outlined below.
NOTE:
The 4WD indicator light may not turn off immediately under certain driving conditions, such as when the vehicle is driven
uphill. This is normal and it will shut off as the vehicle is driven further.
AUTO-LOCK HUB DISENGAGEMENT (FREE MODE)
The AUTO-LOCK hubs will not disengage until the vehicle is completely stopped and is then moved in a straight line, approxi-
mately 7-10 feet (2-3 m), in the opposite direction of travel. For example:
If you were driving the vehicle forward, stop and move the vehicle 7-10 feet (2-3 m) backward.
If you were driving the vehicle in reverse, stop and move the vehicle 7-10 feet (2-3 m) forward.
It is not necessary to immediately return the AUTO-LOCK hubs to FREE MODE when shifting from 4H to 2H. The vehicle may be
operated under normal 2H conditions with the AUTO-LOCK hubs engaged. However, disengaging the AUTO-LOCK hubs will al-
low for better fuel economy, quieter ride and less component wear. Leaving the hubs locked while driving in 2H may be desir-
able so that you can easily shift to 4H at speeds greater than 25 MPH (40 km/h).
From 4H to 4L or 4L to
4H1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 4L or 4H position. Change gears quickly and smoothly.
From 2H to 4L1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 4L position. Change gears quickly and smoothly.
From 4L to 2H1. Stop the vehicle.
2. Depress the clutch pedal, or place the transmission selector lever in the N (Neutral) position.
3. Depress the transfer case shift lever and move it to the 2H position. Change gears quickly and smoothly.
4. Disengage the AUTO-LOCK hubs following the procedure outlined above.

CAUTION
cNEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
cNever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, consult an authorized NISSAN
dealer.
7-6Appearance and care
ZX

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the selector
lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cNever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
cNever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.cIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
cIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
cNever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel tank and bat-
tery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSANdealer because the fuellines are un-
der high pressure even when the
engine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
cAvoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.
