WARNING LIGHTS
orAnti-lock brake warn-
ing light
If the light comes on while the engine is
running, it may indicate the anti-lock brake
system is not functioning properly. Have the
system checked by an authorized NISSAN
dealer.
If an abnormality occurs in the system, the
anti-lock function ceases but the ordinary
brakes continue to operate normally.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
Automatic transmission oil
temperature warning light
(
model)
This light comes on when the automatic
transmission oil temperature is too high. If
the light comes on while driving, reduce the
vehicle speed as soon as safely possible
until the light turns off.
CAUTION
Continued vehicle operation when the
A/T oil temperature warning light is on
may damage the automatic transmis-
sion.
Automatic transmission park
warning light (
model)
This light indicates that the automatic trans-
mission parking function is not engaged. If
the transfer control shift lever is not secured
in any drive position while the automatic
transmission selector lever is in the P (Park)
position, the vehicle may move unexpect-
edly.
Shift the transfer control shift lever into the
2H, 4H, or 4L position when the warning
light comes on.
cWhen parking, always make sure that the
transfer control shift lever is in 2H, 4H, or
4L and the parking brake is set.
cIf the ATP light is ON, this indicates that
the automatic transmission P (Park) po-
sition will not function and the transfer
control shift lever is in the N (Neutral)
position.c
Failure to engage the transfer control shift
lever in 2H, 4H, or 4L could result in the
vehicle moving unexpectedly, resulting in
serious personal injury or property dam-
age.
WARNING
cIf the ATP light is ON, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer control shift lever is in
the N (Neutral) position.
orBrake warning
light
This light functions for both the parking
brake and the foot brake systems.
When the ignition key is in the ON position,
the light comes on when the parking brake
is applied and also warns of a low brake
fluid level. If the light comes on while the
engine is running with the parking brake not
applied, stop the vehicle and perform the
following:
1.
Check the brake fluid level. Add brake fluid
as necessary. See ``Brake and clutch fluid''
Instruments and controls2-11

in the ``Maintenance and do-it-yourself''
section of this manual.
2. If the brake fluid level is correct, have the
warning system checked by an autho-
rized NISSAN dealer.
WARNING
c
Your brake system may not be work-
ing properly if the warning light is on.

judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise have your vehicle towed
because driving it could be danger-
ous.
cPressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stop-
ping distance and require greater
pedal effort as well as pedal travel.
cIf the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at
an authorized NISSAN dealer.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging system
is not functioning properly. Turn the engine

loose, broken, missing or if the light remains
on, see an authorized NISSAN dealer im-
mediately.
CAUTION
Do not continue driving if the belt is
loose, broken or missing.
Door open warning light (if
so equipped)
This light comes on when any of the doors
are not closed securely while the ignition
key is in the ON position.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop
the engineimmediatelyand call an autho-
rized NISSAN dealer.The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level.

tion of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine
as soon as it is safe to do so.
Low fuel warning light
This light comes on when the fuel in the tank
is low. Refuel as soon as it is convenient,
preferably before the fuel gauge reaches E
(Empty).
There will be a small reserve of fuel
remaining in the tank when the fuel
gauge needle reaches E (Empty).

2.Automatic transmission:
Move the selector lever to P (Park) or N
(Neutral). P (Park) is preferred.
The selector lever cannot be moved
out of P (Park) and into any of the
other gear positions if the ignition key
is turned to OFF or if the key is re-
moved from the ignition switch.
The starter is designed not to operate
if the selector lever is in one of the
driving positions.
Manual transmission:
Move the shift lever to N (Neutral), and
fully depress the clutch pedal to the floor
while starting the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3.With your foot off the accelerator
pedal,turn the ignition key to START.
Release the key when the engine starts.
If the engine starts, but fails to run, repeat
the above procedure.cIf the engine is very hard to start in
extremely cold or hot weather, depress
the accelerator pedal fully and hold it
to help start the engine.
cIn the summer, when restarting the
engine within 30 minutes after it has
been stopped, keep the accelerator
pedal fully depressed while starting.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, other-
wise the starter could be damaged.

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.cAccelerating quickly from a stop af-
ter shifting from two-wheel drive to
four-wheel drive may not allow en-
gagement of the auto-locking free-
running hubs and may cause a clat-
tering noise. Continued use of the
vehicle with this noise may damage
the hub lock. In such a case, release
the accelerator pedal to reduce the
engine speed or stop the vehicle.
cIf the auto-locking hubs make a clat-
tering noise after shifting from four-
wheel drive to two-wheel drive, stop
and move the vehicle in reverse
gear, in a straight line, about 7 to 10
feet (2 to 3 m).
cUnder extremely cold conditions
[below 5ÉF (-15ÉC)], the front axle
shafts may rotate even with the
transfer lever in the 2H position. If
this occurs, the auto-locking hubs
may make a clattering noise. To
avoid this, drive first in four-wheel
drive to warm up the vehicle and
differential gear oil. Then, shift to
two-wheel drive.

ZX

Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.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.
