2002 NISSAN XTERRA ECU

WARNING
ODo not leave children, unreliable
adults, or pets alone in your vehicle.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on
hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or pos-
sibly fatal injuries to people or ani-
mals.
OProperly secure all cargo to help
prevent it from sliding or shifting. Do
not place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
ODo not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
a dangerous. It can cause uncon-
sciousness or death.OIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows fully open, and have the
vehicle inspected immediately.
ODo not run the engine in closed
spaces such as a garage.
ODo not park the vehicle with the
engine running for any extended
length of time.
OKeep the back door and rear win-
dows closed while driving, other-
wise exhaust gases could be drawn
into the passenger compartment. If
you must drive with the back door or
rear windows open, follow these pre-
cautions:
1. Open all the windows.
2. Set the air recirculation switch
OFF and the fan control at 4 (high)
to circulate the air.
OIf electrical wiring or other cable
connections must pass to a trailer
through the seal on the back door or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle.O
If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if the
vehicle is parked. Some recreational
vehicle appliances such as stoves,
refrigerators, heaters, etc. may also
generate carbon monoxide.
OThe exhaust system and body
should be inspected by a qualified
mechanic whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.
d.
You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
PRECAUTIONS WHEN
STARTING AND DRIVING
5-2Starting and driving
ZX

OMany hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over.
ODo not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
OStay alert when driving to the top of
a hill. At the top there could be a
drop-off or other hazard that could
cause an accident.
OIf your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
gear. Never back down in N (Neutral)
or with the clutch depressed
(manual transmission vehicles), us-
ing only the brake, as this could
cause loss of control.
OHeavy braking going down a hill-
could cause your brakes to over heatand fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
OUnsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
OTo avoid raising the center of gravity
excessively, do not exceed the rated
capactiy of the roof rack/gear bin (if
so equipped) and evenly distribute
the load. Secure heavy loads in the
cargo area as far forward and as low
as possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-
hicle to roll over.
ODo not grip the inside or spokes of
the steering wheel when driving
offroad. The steering wheel could
move suddenly and injure your
hands. Instead drive with your fin-
gers and thumbs on the outside of
the rim.OBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
OAlways drive with the floor mats in
place as the floor may become hot.
OLower your speed when encoutering
strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.
ODo not drive beyond the perfor-
mance of the tires, even with 4WD
engaged.
OAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
OIf at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four wheel
drive vehicle has a higher center of
gravity than a two-wheel drive ve-
hicle. The vehicle is not designed for
cornering at the same speeds as
conventional two-wheel drive ve-
hicles. Failure to operate this vehicle

COLD pressure:
After vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the
tire placard affixed to the inside of the
glove box lid.
ORetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
5. Securely store the flat tire and jacking
equipment in the vehicle.
WARNING
Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can be-
come dangerous projectiles in an acci-
dent or sudden stop.To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
OIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could
also damage your vehicle.
OExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
ODo not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
OKeep battery out of the reach of
children.
OThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.OYour vehicle has and automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.
OWhenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (for example, goggles or in-
dustrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery when jump starting.
ODo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
WARNING
Always follow the instructions be-
low. Failure to do so could result in
damage to the charging system and
cause personal injury.
1.
If the booster battery is in another vehicle,
position the two vehicles to bring their
batteries into close proximity to each other.

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
