ignition NISSAN PATHFINDER 2002 R50 / 2.G Repair Manual

Part time 4WD models:
IIf the ATP light is ON, this indicates
that the automatic transmission P
(park) position will not function and
the transfer shift lever is in the N
position. Failure to engage the trans-
fer shift lever in H or 4L could result
in the vehicle moving unexpectedly,
resulting in serious personal injury or
property damage.
All-mode 4WD models:
IIf the ATP light is ON, this indicates
that the automatic transmission P
(park) position will not function and
the transfer case is in neutral. Make
sure that the 4WD shift indicator light
(and transfer 4LO position indicator)
light remains illuminated before stop-
ping the engine. Otherwise, the ve-
hicle could unexpectedly move even
if the automatic transmission is in the
P (park) position.
3. To help prevent the vehicle rolling into the
street when parked on a sloping drive way,it is a good practice to turn the wheels as
illustrated.
IHEADED DOWNHILL WITH CURB:
q1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
IHEADED UPHILL WITH CURB:
q2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
IHEADED UPHILL OR DOWNHILL, NO
CURB:
q3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
Make sure the ATP light is off before stop-
ping the engine.
4. Turn the ignition key to the LOCK position
and remove the key.The power assisted steering is designed to
use a hydraulic pump, driven by the engine, to
assist steering.
If the engine stops or drive belt breaks, you will
still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns or at low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
much harder to operate.POWER STEERING

conditions are hazardous and extra care is
required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning light
may come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.Self-test featureThe anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter has a built-in diagnostic feature that tests
the system each time you start the engine and
move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the ABS
brake warning light in the dashboard. The
brake system will then behave normally, but
without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at
your earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type asspecified on the tire placard. See
ªTire placardº in the ª9. Technical
and consumer informationº section
for tire placard location information.

TOWING RECOMMENDED BY
NISSAN
Two wheel drive modelsNISSAN recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed truck
as illustrated.
CAUTION
INever tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive damage
to the transmission. If it is necessary
to tow the vehicle with the front
wheels raised, always use towing dol-
lies under the rear wheels.
IWhen towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:
ITurn the ignition key to the OFF
position, and secure the steeringwheel in a straightahead 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.
IIf you have to tow manual transmis-
sion models with the rear wheels on
the ground or four wheels on the
ground (if you do not use towing
dollies):
IAlways release the parking brake.
IMove the transmission shift lever
to the N (Neutral) position.
IObserve the following restricted tow-
ing speeds and distances for manual
transmission models only:
ISpeed: Below 60 MPH (95 km/h)
IDistance: Less than 500 miles (800
km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before tow-
ing to prevent damage to the transmission.

See ªPrecautions when starting and drivingº in
the ª5. Starting and drivingº 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 exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see ªCleaning
exteriorº in the ª7. Appearance and careº sec-
tion.
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 cor-
rected immediately.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.

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
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 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
available. See ªOwner's Manual/Service
Manual order informationº in the ª9. Technical
and consumer informationº section.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt about
any servicing, have it done by your NISSAN
dealer.8-6

REPLACING SPARK PLUGS
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 toremove the spark plugs. An incorrect
socket can cause damage the 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.
Always replace with recommended
platinum-tipped spark plugs.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 shown in a separate maintenance
booklet for maintenance intervals. When re-
placing the filter, wipe the inside of the air
cleaner housing and the cover with a damp
cloth.
