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 automatic transmission fluid should
be warmed to between 122É and 176ÉF
(50É to 80ÉC).
cThe fluid can be checked at fluid tem-
peratures of 86É to 122ÉF (30 to 50ÉC)
using the COLD range on the dipstick,
after 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 shift
selector lever through each gear range.
Move the shift selector lever to P (Park)
after you have moved it through all
ranges.

BRAKE FLUID
Check the brake fluid level in the reservoir. If
the fluid level is below the MIN line or the
brake warning light comes on, add Genuine
Nissan Brake Fluid or equivalentDOT 3fluid
up to the MAX line. If fluid must be added
frequently, the system should be thoroughly
checked by an authorized NISSAN dealer.
CLUTCH FLUID
Check the clutch fluid level in the reservoir
(manual transmission only). If the fluid level
is below the MIN line, add Genuine Nissan
Brake Fluid or equivalentDOT 3fluid up to
the MAX line. If fluid must be added fre-
quently, the system should be thoroughly
checked by an authorized 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 damage the brake system and af-
fect the vehicle's stopping ability.
CAUTION
Do not spill the fluid on painted sur-
faces. This will damage the paint. If
fluid is spilled, immediately wash the
surface with water.

Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
(QR25DE)
1. Disconnect the negative battery cable.
2. Remove the coil pack bolt.
3. Remove the coil pack/spark plug boot
from the spark plug.
4. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so it does not fall
when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.5. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 Nzm)
6. Install the coil pack/spark plug boot on
the spark plug by pushing it on until you
feel a snap.
7. Install the coil pack bolt.
Coil pack tightening torque:
48-65 in-lb
(5.4 - 7.3 Nzm)
8. Connect the negative battery cable.

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, pull the parking
brake lever up slowly and firmly. 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 the distance
between the upper surface of the pedal and
the metal floor. 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 and rear, disc-type brakes self-
adjust every time the brake pedal is applied.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes 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.
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 as fol-
lows:
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 the
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. Keep 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, see an
authorized NISSAN dealer.
CHECKING CLUTCH PEDAL
Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see an authorized NISSAN dealer.

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 wheels and tires
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
``wheels/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
c
The use of tires other than those rec-
ommended, or the mixed use of tires
of different brands, construction (bias,
bias-belted, radial), or tread patternscan 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 off-set dimen-
sion. Wheels of a different off-set
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 con-
sumer information'' section of this
manual for wheel off-set dimen-
sions.
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.
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).
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 per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
cFor additional information regarding
tires, refer to ``Important Tire Safety In-
formation'' in the Warranty Information
Booklet (US) or ``Tire Safety Informa-
tion'' in the Warranty and Roadside As-
sistance Information Booklet (Canada).
