1997 NISSAN MAXIMA engine

Platinum-tipped spark plug
It is not necessary to replace the platinum-
tipped spark plugs as frequently as the con-
ventional type spark plugs since they will last
much longer. Follow the maintenance sched-
ule but, do not reuse them by cleaning or
regapping.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals shown in the ªMaintenance
scheduleº section. When replacing the filter,
wipe the inside of the air cleaner housing and
the cover with a damp cloth.
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 back-
fires. If it is not there, and the engine

backfires, you could be burned. Do not
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 a wiper blade chat-
ters 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 clearafter cleaning the blades and using the
wiper, replace the blades.
2) REPLACEMENT
1. Pull the wiper arm.
2. Push the lock pin, then remove the wiper
blade.
3. Insert the new wiper blade to the wiper arm
until a click sounds.

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.
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.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
your NISSAN dealer.

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 your NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
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 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 indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate main-
tenance schedule information in the ªMainte-
nance Scheduleº section of this manual.

Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains 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 decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, see your
NISSAN dealer.Press the pedal by hand and be sure the free
travel is within the limits shown above. If free
travel is too little or too much, see your NIS-
SAN dealer.

If any electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine NISSAN
parts.
HEADLIGHTS
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halogen)
bulb. A bulb can be replaced from inside the
engine compartment without removing the
headlight assembly.
High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
Hold the plastic base when handling the
bulb. Never touch the glass envelope.

Your new NISSAN has been designed to have
minimum maintenance requirements with
longer service intervals to save you both time
and money. However, some day-to-day and
regular maintenance is essential to maintain
your NISSAN's good mechanical condition, as
well as its emission and engine performance.
It is the owner's responsibility to make sure
that the specified maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives the
proper maintenance care. You are a vital link
in the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
your NISSAN dealer.
Periodic maintenance
The maintenance items listed in this part are
required to be serviced at regular intervals.However, under severe driving conditions, ad-
ditional or more frequent maintenance will be
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and tuned by an authorized
NISSAN dealer.
NISSAN technicians are well-trained special-
ists and are kept up to date with the latest
service information through technical bulletins,
service tips, and in-dealership training pro-
grams. They are completely qualified to work
on NISSAN's vehiclesbeforethey work on
your vehicle, rather than after they have
worked on it.
You can be confident that your NISSAN deal-
er's service department performs the best job
to meet the maintenance requirements on your
vehicle Ð in a reliable and economic way.
