2004 NISSAN PATHFINDER key

CAUTION

Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground,
as this may cause serious and expen-
sive damage to the transmission. If it
is necessary to tow the vehicle with
the front wheels raised, always use
towing dollies under the rear wheels.

When towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:

Move the transfer case shift lever
to the 2H position.

Turn the ignition key to the OFF
position, and secure the steering
wheel in a straight ahead position
with a rope or similar device. Never
secure the steering wheel by turn-
ing the ignition key to the LOCK
position. This may damage the
steering lock mechanism.
If you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the ground:

Move the transfer case shift lever
to the 2H position.

Move the transmission shift lever
to the N(Neutral) position.

Always release the parking brake.

Observe the following restricted tow-
ing speeds and distances manual
transmission models only:

Speed: Below 60 MPH (95 km/h)

Distance: Less than 500 miles (800
km)
If the speed or distance must necessarily be
greater, remove the front and rear propeller
shafts before towing to prevent damage to the
transmission.

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.

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
