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.

WARNING
cWhen the engine is running, keep
hands, jewelry and clothing away
from any moving parts such as the
cooling fan and drive belts.
cAutomatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
TEMPERATURE CONDITIONS
FOR CHECKING
cThe fluid level should be checked using
the HOT range on the dipstick after the
following conditions have been met:
Ð The engine should be warmed up to
operating temperature.
Ð The vehicle should be driven at least 5
minutes.
Ð The ATF should be warmed to between
122 and 176ÉF (50 and 80ÉC).
cThe ATF can be checked at fluid tem-
peratures of 86 to 122ÉF (30 to 50ÉC)
using the COLD range on the dipstickafter the engine is warmed up and before
driving. However, the fluid should be re-
checked using the HOT range.
1. Park the vehicle on a level surface and
set the parking brake.
2. Start the engine and then move the se-
lector lever through each gear range,
ending in P (Park).3. Check the fluid level with the engine
idling.
4. Remove the dipstick and wipe it clean
with lint-free paper.
5. Re-insert the dipstick into the charging
pipe as far as it will go.
6. Remove the dipstick and note the read-
ing. If the level is on the low side of either
range, add fluid through the charging
pipe.

tomatic transmission fluid.
NOTE:
If the vehicle has been driven for a long
time at high speeds, or in city traffic in
hot weather, or if it is being used to pull
a trailer, the fluid level cannot be read
accurately. You should wait until the
fluid has cooled down (about 30 min-
utes).The fluid level should be checked using the
HOT MAX range on the power steering fluid
reservoir at fluid temperatures of 122 to
176ÉF (50 to 80ÉC) or using the COLD MAX
range on the power steering fluid reservoir
at fluid temperatures of 32 to 86ÉF (0 to
30ÉC).

Check the brake fluid level in the reservoir.
If the fluid level is below the MIN line or the
brake warning light comes on, addDOT 3
fluid up to the MAX line.
Check the clutch fluid level in the reservoir
(manual transmission only). If the fluid level
is below the MIN line, addDOT 3fluid up to
the MAX line.
If fluid must be added frequently, the system
should be thoroughly checked by an autho-
rized NISSAN dealer.For further brake and clutch fluid specifica-
tion information, refer to ``Capacities and
recommended fuel/lubricants'' in the ``Tech-
nical and consumer information'' section of
this manual.
WARNING
Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake and clutch
systems. The use of improper fluids
can affect the vehicle's stopping abil-
ity.
CAUTION
Do not spill the fluid on painted sur-
faces. This will damage the paint. If
fluid is spilled, wash the surface with
water.WINDOW WASHER FLUID
RESERVOIR
Follow the manufacturer's instructions for
the mixture ratio.
CAUTION
cDo not substitute engine anti-freeze

If it is out of the range shown above, see an
authorized NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see an authorized NIS-
SAN dealer and have it checked.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by an authorized NIS-
SAN dealer.Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.
BRAKE BOOSTER
Check the brake booster function with the
following steps:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-

cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
Replacing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
c
The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.cIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause pre-mature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. Refer to(Wheel/tire size(in the
(Technical and consumer informa-
tion(section of this manual for wheel
off-set dimensions.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have unknown
structural damage and could fail
without warning.
cThe use of retread tires is not recom-
mended.
Four-wheel drive models
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact an
authorized NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.

for smooth operation and make sure it has
the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission P (Park) posi-
tion mechanismCheck that the lock re-
lease button on the selector lever operates
properly and smoothly. On a fairly steep hill
check that your vehicle is held securely with
the selector lever in the P position without
applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine oil level*Check the level afterparking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
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.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.
