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 oil pressure warning light is not
designed to indicate a low oil level. Use
the dipstick to check the oil level.See
``Engine oil'' in the ``Do-it-yourself'' section
of this manual.
CAUTION
Running the engine with the oil pres-
sure warning light on could cause seri-
ous damage to the engine almost im-
mediately. Turn off the engine as soon
as it is safe to do so.
Charge warning light
If this light comes on while the engine is
running, it may indicate a problem with the
charging system. Turn the engine off and
check the generator belt. If the belt is loose,
broken, missing or if the light remains on, see
an authorized NISSAN dealer immediately.
CAUTION
Do not continue driving if the belt is
loose, broken or missing.

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).
Low washer fluid warning
light (Canada only)
This light comes on when the washer tank
fluid is at a low level. Add washer fluid as
necessary. See ``Window washer fluid'' in

cMake sure the area around the vehicle is
clear.
cCheck fluid levels such as engine oil,
coolant, brake and clutch fluid, and win-
dow washer fluid as frequently as pos-
sible, at least whenever you refuel.
cCheck that all windows and lights are
clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers
to do likewise.
c
Check the operation of warning lights when
key is turned to the ON (3) position. See
``Warning/indicator lights and chimes'' in
the ``Instruments and controls'' section.
WARNING
cDo not depress the accelerator pedal
while shifting from P (Park) or N
(Neutral) to R (Reverse), D (Drive), 2
or 1. Always depress the brake pedal
until shifting is completed. Failure to
do so could cause you to lose con-
trol and have an accident.
cCold engine idle speed is high, so
use caution when shifting into a for-
ward or reverse gear before the en-
gine has warmed up.
cNever shift to P (Park) or R (Reverse)
while the vehicle is moving. This
could cause an accident.
CAUTION
cWhen stopping the vehicle on an
uphill grade, do not hold the vehicle
by depressing the accelerator pedal.
The foot brake should be used for
this purpose.
cOn slippery roads, do not downshift.
This may cause a loss of control.
The automatic transmission in your vehicle
is electronically controlled by a transmission
control module to produce maximum power
and smooth operation.
The recommended operating procedures for
this transmission are shown on the following
pages. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
cAfter starting the engine, fully depress
the foot brake pedal to ensure the vehicle
is at a complete stop before attempting to
shift the selector lever.
cKeep the foot brake pedal depressed and
shift the selector lever into a driving gear.
cRelease the foot brake, then gradually
start the vehicle in motion.
This automatic transmission is designed
so the foot brake pedal MUST be de-
pressed before shifting from P (Park) to
any drive position while the ignition
switch is ON.
The shift lever cannot be moved out of P
(Park) and into any of the other gear
positions if the ignition key is turned to
LOCK or if the key is removed.
If the battery charge is low, the shift lever
can be moved if the ignition switch is in
the ACC position.

mud or deep snow. The 4L position pro-
vides maximum power and traction. Avoid
raising vehicle speed excessively, as the
maximum speed in 5th gear is approxi-
mately 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.
Your NISSAN is equipped with one of two
4WD systems, auto-lock free-running hubs
or manual-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 about 7 to 10
feet (2 to 3 m) in reverse.
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.

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 a manual
transmission, move the shift lever to
N (Neutral). For an automatic trans-
mission, move the shift lever to P
(Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
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 remove ties and 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.
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 and battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under 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 motor oil.
Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local 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.
