2000 NISSAN PATHFINDER maintenance

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNING
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.
IBe sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.
IIt is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IYour vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable before
working near the fan.
IOn gasoline engine models with themultiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
IDo not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil. Improperly disposed motor oil and/
or other vehicle fluids can hurt the
environment. Always conform to lo-

tion and tension in accordance with the
maintenance schedule in this manual.
REPLACING SPARK PLUGS
Platinum-tipped spark plugsIt 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.
If replacement is required, see your NISSAN
dealer for servicing.
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 cause damage the spark
plugs.
Always replace spark plugs with recom-
mended or equivalent ones.

The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance intervals. See ªPeriodic mainte-
nanceº in the ª9. Maintenanceº section for
maintenance intervals. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING
IOperating the engine with the air
cleaner removed can cause you orothers to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful working on the engine with the air
cleaner removed.
INever pour fuel into the throttle body
or attempt to start the engine with the
air cleaner removed. Doing so could
result in serious injury.

Self-adjusting brakesYour 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 self-adjust every time the
parking brake 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
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe 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.
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 your NISSAN dealer.
Proper brake inspection intervals should
be followed.For additional information, see
ªPeriodic maintenanceº in the ª9. Mainte-
nanceº section for maintenance intervals.
BRAKE BOOSTERCheck 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) 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 forabout 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, have the
brake checked by your NISSAN dealer.

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 vehicles before they 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.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have
your NISSAN dealer do it promptly. In addition,
you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, see ªMaintenance precautionsº in the ª8.
Do-it-yourselfº section.
EXTERIOR MAINTENANCEAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*:
Check the pressure with a gauge periodically
when at a service station, including the spare,
and adjust to the specified pressure if neces-
sary. Check carefully for damage, cuts or
excessive wear.

Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rota-
tion may vary according to your driving habits
and road surface conditions.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Doors and engine hood:
Check that all doors and the engine hood,
operate properly. Also ensure that all latches
lock securely. Lubricate hinges, latches, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from openingwhen the primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Inside the vehicleLights*:
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also

such as excessive freeplay, hard steering or
strange noises.
Seats:
Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and
that the locks (if so equipped) hold securely in
all latched positions.
Seat belts:
Check that all parts of the seat belt system
(e.g. buckles, anchors, adjusters and retrac-
tors) operate properly and smoothly, and are
installed securely. Check the belt webbing for
cuts, fraying, wear or damage.
