2004 NISSAN PATHFINDER do-it-yourself

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all operat-
ing properly and installed securely. Also check
headlight aim.
Road wheel nuts (lug nuts)*:
When checking the tires, make sure no wheel
nuts are missing, and check for any loose wheel
nuts. Tighten if necessary.
Tires*:
Check the pressure with a gauge often and
always prior to long distance trips. If necessary,
adjust the pressure in all tires, including the
spare, to the pressure specified. 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 rotation
may vary according to your driving habits and
road surface conditions.
Tire, wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if youdetect 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.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.
Windshield:
Clean the windshield on a regular basis. Check
the windshield at least every six months for
cracks or other damage. Have a damaged wind-
shield repaired by a qualified repair facility.
Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal:
Check the pedal for smooth operation and make
sure the pedal does not catch or require uneven
effort. Keep the floor mats away from the pedal.Automatic transmission P (Park) position
mechanism:

operate smoothly and that all latches lock se-
curely 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 retractors) op-
erate properly and smoothly, and are installed
securely. Check the belt webbing for cuts, fray-
ing, wear or damage.
Steering wheel:
Check for changes in the steering conditions,
such as excessive freeplay, hard steering or
strange noises.
Warning lights and chimes:
Make sure that all warning lights and chimes are
operating properly.
Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in sufficient quantity when
operating the heater or air conditioner.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Under the hood and vehicleThe maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Automatic transmission fluid level*:
Check the level after putting the selector lever in
P (Park) with the engine idling.
Battery*:
Check the fluid level in each cell. It should be
between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*:
Make sure that the brake and clutch fluid level is
between the MAX and MIN lines on the reservoir.
Engine coolant level*:
Check the coolant level when the engine is cold.
Engine drive belts*:
Make sure that no belt is frayed, worn, cracked
or oily.
Engine oil level*:
Check the level after parking the vehicle on alevel spot and turning off the engine. (Be sure to
wait a few minutes to allow the oil to drain back
into the sump.)
Exhaust system:
Make sure there are no loose supports, cracks or
holes. If the sound of the exhaust seems unusual
or there is a smell of exhaust fumes, immediately
locate the trouble and correct it. See “Precau-
tions when starting and driving” in the “5. Start-
ing and driving” section for exhaust gas (carbon
monoxide).
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.
Power steering fluid level* and lines:
Check the level when the fluid is cold and the
engine is turned off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accumu-
lated. Make sure the hoses have no cracks,

deformation, rot or loose connections.
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.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.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.

cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level, add coolant 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 coolant in the radia-
tor, fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank up
to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
