2003 NISSAN PATHFINDER oil

If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
indicator light goes out.
High-temperature transfer case oil makes the
warning light blink rapidly (about twice per sec-
ond). If the warning light blinks rapidly during
operation, stop the vehicle in a safe place imme-
diately. Then if the light goes off after a while, you
can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds).
Change the 4WD shift switch into 2WD and do
not drive fast.
CAUTION

If the warning light comes on or
blinks slowly during operation or rap-
idly after stopping the vehicle for a
while, have your vehicle checked by
an authorized NISSAN dealer as
soon as possible.

Shifting between 4H and 4LO is notrecommended when the 4WD warn-
ing light turns on.

When the warning light comes on,
the 2WD mode may be engaged even
if the 4WD shift switch is in AUTO or
4H. Be especially careful when driv-
ing. If corresponding parts are mal-
functioning, the 4WD mode will not
be engaged even if the 4WD shift
switch is shifted.

Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surface roads in 4H or
4L may cause unnecessary noise, tire
wear and increased fuel consump-
tion.
If the 4WD warning light turns on
when you are driving on dry hard
surface roads

in the AUTO or 4H position, shift
the 4WD shift switch to 2WD.

in the 4LO position, stop the ve-
hicle, move the automatic trans-
mission lever to the Nposition,and shift the 4WD shift switch to
2WD.

If the warning light is still on after the
above operation, have your vehicle
checked by an authorized NISSAN
dealer as soon as possible.

The transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.

Installing the spare tire1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly until they are tight.
4. Lower the vehicle slowly until the tire touches
the ground. Then, with the wheel nut wrench,
tighten the wheel nuts securely in the se-
quence as illustrated.
WARNING

Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.

Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
As soon as possible tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
98 ft-lb (133 N⋅m)

ing. Follow the instructions supplied with the
wax.

Do not use a wax containing any abrasives,
cutting compounds or cleaners that may
damage the vehicle finish.

If the surface does not polish easily, use a
road tar remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint
finish may dull the finish or leave swirl
marks.
Only apply black wax or black shoe polish to the
black urethane or polypropylene bumper.
REMOVING SPOTSRemove tar and oil spots, industrial dust, insects
and tree sap as quickly as possible from the
surface of the paint to avoid lasting damage or
staining. Special cleaning products are available
at your NISSAN dealer or any automotive acces-
sories store.UNDERBODYIn areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up
and causing corrosion on the underbody and
suspension. Before the winter period and againin the spring, the underseal must be checked
and, if necessary, re-treated.
GLASSUse glass cleaner to remove smoke and dust film
from the glass surfaces. It is normal for glass to
be coated with a film after the vehicle is parked
in the hot sun. Glass cleaner and a soft cloth will
easily remove this film.
CAUTION
When cleaning the inside of the win-
dow, do not use sharp-edged tools,
abrasive cleaners or chlorine based dis-
infectant cleaners. They could damage
the electrical conductors, radio antenna
elements or rear window defogger ele-
ments.ALUMINUM ALLOY WHEELSWash regularly, especially during winter months
in areas where road salt is used. Salt could
discolor the wheel if not removed.CHROME PARTSClean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft brush. Wipe the vinyl and leather
surfaces with a clean, soft cloth dampened in
mild soap solution, then wipe clean with a dry
soft cloth. Before using any fabric protector,
read the manufacturer’s recommendations.
Some fabric protectors contains chemicals that
stain or bleach the seat material. Use a cloth
dampened only with water, to clean the meter
and gauge lens.
CAUTION

Never use gasoline, thinner or any
similar material.

The leather seats should be regularly
coated with a leather wax like saddle
soap. Never use car wax.

Never use fabric protectors unless
recommended by the manufacturer.

Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.CLEANING INTERIOR

confirm that your vehicle is held securely on a
fairly steep hill with only the parking brake ap-
plied.Automatic transmission P (Park) position
mechanism:
On a fairly steep hill check that your vehicle is
held securely with the selector lever in the P
position without applying any brakes.
Under the hood and vehicleThe maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. (Be sure to
wait a few minutes to allow the oil to drain back
into the sump.)
Brake and clutch fluid levels*:
Make sure that the brake and clutch fluid level is
between the MAX and MIN lines on the reservoir.
Power steering fluid level* and lines:
Check the level when the fluid is cold and the

ing and driving” section for exhaust gas (carbon
monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING

Park 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.

Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.

If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.

It is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never 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.

Keep smoking materials, flame and
sparks away from fuel and battery.

Your 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 be-
fore working near the fan.

multiport 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

Do not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.

Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.

Never leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.

Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can hurt the envi-ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This section gives instructions regarding only
those items which are relatively easy for an
owner to perform. More involved service should
be done by your NISSAN dealer.
A genuine NISSAN Service Manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “9. Technical and con-
sumer information” section.
You should be aware that incomplete or im-
proper servicing may result in operating difficul-
ties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, have it done by your NISSAN
dealer.8-6

CHECKING ENGINE OIL LEVEL1. Park the vehicle on a level surface and apply
the parking brake.
2. Run the engine until it reaches operating
temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Rein-
sert it all the way.
5. Remove the dipstick again and check the oil
level. It should be between the H and Lmarks. If the oil level is below the L mark,
remove the oil filler cap and pour recom-
mended oil through the opening. Do not
overfill.
6. Recheck oil level with dipstick.
It is normal to add some oil between oil
changes or during the break-in period, de-
pending on the severity of operating con-
ditions.
CAUTION
Oil level should be checked regularly.
Operating with insufficient amount of
oil can damage the engine, and such
damage is not covered by warranty.
