TEMPERATURE CONDITIONS
FOR CHECKING ATF
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 122 and 176ÉF
(50 and 80ÉC).
cThe fluid can be checked at fluid tem-
peratures of 86 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
lever through each gear range. Move the
shift lever to P (Park) after you have
moved it through all ranges.3. Check the fluid level with the engine
idling.
4. Remove the dipstick and wipe it clean
with lint-free paper.
5. Reinsert 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 at the low side of either
range, add fluid to the charging pipe.

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 accurate fluid level cannot
be read. You should wait until the fluid
has cooled down (about 30 minutes) be-
fore checking fluid level.
Check the fluid level in the reservoir.
The fluid level should be checked using the
HOT range on the side of the fluid reservoir
at fluid temperatures of 122 to 176ÉF (50 to
80ÉC) or using the COLD range on the side
of the fluid reservoir at fluid temperatures of
32 to 86ÉF (0 to 30ÉC).
CAUTION
cDo not overfill.
cRecommended fluid is type
DEXRON

Check the brake fluid level in the reservoir.
If the fluid is below the MIN line or the brake
warning light comes on, addDOT 3fluid up
to the MAX line. If fluid must be added
frequently, the system should be thoroughly
checked by your NISSAN dealer.
WARNING
Use only new fluid. Old, inferior, or
contaminated fluid may damage the
brake system. The use of improper flu-
ids can damage the brake system and
affect the vehicle's stopping ability.
CAUTION
Do not spill the fluid on painted sur-
faces. This will damage the paint. If
fluid is spilled, wash with water.
For USA
Fill the window washer fluid reservoir peri-
odically. Perform the refilling operation
more often under driving conditions that
require an increased amount of window
washer fluid.
To fill the window washer fluid reservoir, lift
the cap off the reservoir tank and pour the
window washer fluid into the tank opening.
Add a washer solvent to the water for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manu-
facturer's instructions for the mixture ratio.

light comes on. Add a washer solvent to the
water for better cleaning. In the winter sea-
son, add a windshield washer antifreeze.
Follow the manufacturer's instructions for
the mixture ratio.
CAUTION
Do not substitute engine antifreeze
coolant for windshield washer solution.
This may result in damage to the paint.cKeep the battery surface clean and dry.
Any corrosion should be washed off with
a solution of baking soda and water.
cMake certain the terminal connections
are clean and securely tightened.
cIf the vehicle is not to be used for 30 days
or longer, disconnect the negative (þ)
battery terminal cable to prevent dis-
charge.
WARNING
cDo not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15 min-
utes and seek medical attention.
cWhen working on or near a battery,
always wear suitable eye protection
and remove all jewelry.
cKeep the battery out of the reach of
children.

1. Remove brackets as necessary to give
access to the high tension cables and
spark plugs.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The spark 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 plug
socket.
4. On conventional spark plugs, check the
gap on each new spark plug with a
feeler gauge. (The spark plug gap is
shown in the ``Technical and consumer
information'' section.) Adjust the gap as
required.
