2002 NISSAN XTERRA ignition

TOWING RECOMMENDED BY
NISSAN
Two-wheel drive models
NISSAN recommends that your vehicle betowed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
ONever 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 dam-
age to the transmission. If it is nec-
essary to tow the vehicle with the
front wheels raised, always use tow-
ing dollies under the rear wheels.
OWhen towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:
OTurn the ignition key to the OFF
position, and secure the steer-
ing wheel in a straight ahead
position with a rope or similar
device. Never secure the steer-
ing wheel by turning the igni-
tion key to the LOCK position.
This may damage the steering
lock mechanism.OIf 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:
OAlways release the parking
brake.
OMove the transmission shift le-
ver to the N (Neutral) position.
OObserve the following re-
stricted towing speeds and dis-
tances for manual transmis-
sion models only:
Speed: Below 60 MPH (97 km/h)
Distance: Less than 500 miles
(805 km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before to
prevent damage to the transmission.

Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
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.
Exhaust systemMake 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 have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck 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 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
OPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift lever
to P (Park).
OBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
ONever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
ONever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.

OIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts, and any other moving parts.
OIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
OAlways wear eye protection when-
ever you work on your vehicle.
OIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
ONever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
OKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
OOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSAN
dealer because the fuel lines are
under high pressure even when the
engine is off.
CAUTION
ODo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
ONever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
ONever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
OAvoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of ve-
hicle fluid.
This ``Maintenance and do-it-yourself'' sec-
tion gives instructions regarding only those
items which are relatively easy for an owner
to perform.
A genuine NISSAN Service Manual is also
available. See ``Owner's Manual/ServiceManual Order Information'' in the ``Technical
and Consumer Information'' Section.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially. Many
of these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 (except supercharger) or 91
(supercharger) AKI (Anti-Knock Index).
However, you may use unleaded gasoline
with an octane rating as low as 85 AKI in
high altitude areas (over 4,000 ft [1,219 m])
such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada,southern Idaho, western South Dakota,
western Nebraska, and the part of Texas
which is directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have an authorized NIS-
SAN dealer correct the condition. Failure
to correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehicle
checked at an authorized NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there islight spark knock for a short time under
heavy engine load.
