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.

THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the converter are burned at
high temperatures to help reduce pollutants.
WARNING
OThe exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system com-
ponents.
ODo not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
CAUTION
ODo not use leaded gasoline. Depos-
its from leaded gasoline will seri-
ously reduce the three-way cata-
lyst's ability to help reduce exhaust
pollutants.
OKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-rich fuel flow into the three-way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires,
or if noticeable loss of performance
or other unusual operating condi-
tions are detected. Have the vehicle
inspected promptly by an authorized
NISSAN dealer.
OAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
ODo not race the engine while warm-
ing it up.
ODo not push or tow your vehicle to
start the engine.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles.
They have higher ground clearance than
passenger cars to make them capable of
performing in a variety of on-pavement and
off-road applications. This gives them ahigher center of gravity than ordinary cars.
An advantage of higher ground clearance is
a better view of the road, allowing you to
anticipate problems. However, they are not
designed for cornering at the same speeds
as conventional two-wheel drive vehicles
any more than low-slung sports cars are
designed to perform satisfactorily under
off-road conditions. If at all possible, avoid
sharp turns or abrupt maneuvers particu-
larly at high speeds. As with other vehicles
of this type, failure to operate this vehicle
correctly may result in loss of control or
vehicle rollover.
Be sure to read the driving safety precau-
tions later in this section.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving

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
