7. Refill engine with a recommended oil
through the oil filler opening then install
the oil filler cap securely.
See ``Capacities and recommended
fuel/lubricants'' in the ``Technical and
consumer information'' section for drain
and refill capacity.
The drain and refill capacity depends on
the oil temperature and drain time. Use
these specifications for reference only.
Always use the dipstick to determine
when the proper amount of oil is in the
engine.
8. Start the engine. Check for leakage
around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait several
minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Remove the splash shield.
cRemove the six push pins.
cRemove the six bolts and the splash
shield.
4.
Place a large drain pan under the oil filter.
5. Loosen the oil filter with an oil filter
wrench. Then remove the oil filter by
turning it by hand.
CAUTION
Be careful not to burn yourself. The
engine oil may be hot.
6. Wipe the engine oil filter mounting sur-
face with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the

8. Screw in the oil filter until a slight resis-
tance is felt, then tighten an additional
2/3 turn.
9. Start the engine and check for leakage
around the oil filter. Correct as required.

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).

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).
CAUTION
cDO NOT OVERFILL.
cRecommended fluid is Genuine
NISSAN PSFII or equivalent.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.

If you wax the surface of the hood, be
careful not to let wax get into the washer
nozzle. This may cause clogging or im-
proper windshield washer operation. If
wax gets into the nozzle, remove it with a
needle or small pin.
CHECKING PARKING BRAKE
From the released position, firmly push the
parking brake down. If the number of clicks
is out of the range listed above, see an
authorized NISSAN dealer.
CHECKING BRAKE PEDAL
With the engine running, check distance A
between the upper surface of the pedal and
the metal floor.

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
NISSAN 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
NISSAN dealer.Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide.''
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-

crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by an authorized
NISSAN dealer.
CHECKING CLUTCH PEDAL
Press the pedal by hand and be sure the
free travel is within the above limit. If free
travel is out of the range shown above, see
an authorized NISSAN dealer.

Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire(s)
should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicators are visible, the tire(s)
should be replaced.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.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
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 premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to(Wheel/tire
size(in the(Technical and consumer
information(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.
