The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ra-
tio. Examples are shown below:

The use of other types of coolant solu-
tions may damage your cooling system.
The radiator is equipped with a pressure
cap. Use a genuine NISSAN cap or its
equivalent when replacement is re-
quired.
Never remove the radiator cap when the
engine is hot. Serious burns could becaused by high pressure fluid escaping
from the radiator.
Wait until the engine and radiator cool
down. See precautions in ``If your ve-
hicle overheats'' found in the ``In Case Of
Emergency'' section.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.

6. Recheck oil level with dipstick.
CAUTION
cOil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.
cIt is normal to add some oil between
oil maintenance intervals or during
the break-in period, depending on the
severity of operating conditions.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating
temperature, and then turn it off.
3. Place a large drain pan under the drain
plug.
4. Remove the oil filler cap.
5. Remove the drain plug with a wrench and
completely drain the oil.If the oil filter is to be changed, remove
and replace it at this time. See ``Chang-
ing engine oil filter'' in this section.

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.

5. Fit the new plugs, one at a time, into the
spark plug socket and install them. Turn
each plug in several full turns by hand,
then tighten with a spark plug socket to
the correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb (20 to 29 N²m)
6. Holding the boot, re-connect each high
tension cable to its proper spark plug by
pushing it on until you feel a snap.
7. Re-install all brackets as necessary.

Platinum-tipped spark plug
It is not necessary to replace the platinum-
tipped spark plugs as frequently as the
conventional type spark plugs since they
last much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping. Blue rings on the
ceramic portion indicate that the plugs are
platinum-tipped.
cAlways replace spark plugs with rec-
ommended or equivalent ones.The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the ``Main-
tenance schedule'' section. When replacing
the filter, wipe the inside of the air cleaner
housing and the cover with a damp cloth.
WARNING
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame if the engine
backfires. If it isn't there, and the engine back-
fires, you could be burned. Don't drive with it off,
and be careful working on the engine with the air
cleaner off.

1) CLEANING
If your windshield is not clear after using
the windshield washer or if the wiper
blade chatters when running, wax or
other material may be on the blade or
windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form
when rinsing with clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild
detergent. Then rinse the blade with
clear water. If your windshield is still not
clear after cleaning the blades and usingthe wiper, replace the blades.
2) REPLACEMENT
1. Pull the wiper arm.
2. Lift the tab, then remove the wiper blade.
3. Insert the new wiper blade to the wiper
arm until a click sounds.
CAUTION
After wiper blade replacement, return
the wiper arm to its original position.
Otherwise it may be damaged when the
engine hood is opened.Make sure the wiper blade contacts the
glass, otherwise the arm may be dam-
aged from wind pressure.

normal, it may be due to a lack of adjust-
ment of the rear drum brakes. Apply the
parking brake several times.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.
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.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise fromthe rear drum brakes, have them inspected
as soon as possible by your NISSAN
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.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. 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, see
your NISSAN dealer.
