FUEL GAUGEThe gauge indicates the APPROXIMATE fuel
level in the tank.
The gauge may move slightly during braking,
turning, acceleration, or going up or down hill.
The gauge needle is designed to remain in
approximately the same position, even when
the ignition key is turned OFF.
Refill the fuel tank before the gauge regis-
ters Empty.
The indicator light comes on when the fuel
tank is getting low. Refuel as soon as it isconvenient, preferably before the gauge
reaches E. There will be a small reserve of
fuel in the tank when the fuel gauge needle
reaches E.
If the vehicle is driven with the fuel level
very low, the malfunction indicator light
may come on. Refuel as soon as pos-
sible. After re-fueling, the light should
go off. If the light remains on, have the
vehicle inspected by an authorized
NISSAN dealer.
For additional information, see the ªMal-
function indicator light (MIL)º later in
this section.

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 CATALYSTThe three way catalyst is an emission control
device, installed in the exhaust system. In the
converter, exhaust gases are burned at high
temperatures to help reduce pollutants.IThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system.
IDo not stop or park the vehicle over
flammable materials, such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
IDo not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst's ability
to help reduce exhaust pollutants.
IKeep 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 conditions
are detected. Have the vehicle in-
spected promptly by an authorized
NISSAN dealer.
IAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
IDo not race the engine while warming
it up.
IDo not push or tow your vehicle to
start the engine.
ON-PAVEMENT AND OFFROAD
DRIVING PRECAUTIONSUtility vehicles have higher ground clearance
than passenger cars and a narrower track to
make them capable of performing in a wide
variety of offroad applications. Specific design
characteristics give them a higher center of
gravity than ordinary cars. An advantage of
higher ground clearance is a better view of the
road, allowing you to anticipate problems.
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
offroad conditions. If at all possible, avoid
sharp turns or abrupt maneuvers. 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 precautions
later in this section.

IMany 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.
IStay 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.
IIf 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 reverse gear. Never
back down in neutral (N) or with the
clutch depressed, using only the
brake, as this could cause loss of
control.
IHeavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
IUnsecured cargo can be thrownaround when driving over rough ter-
rain. Properly secure it so that it will
not be thrown forward and cause in-
jury to you or your passengers.
IAvoid raising the center of gravity by
loading things on the roof or equip-
ping the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to rollover. Put
heavy loads in the cargo area as far
forward and as low as possible.
IDo not grip the inside or spokes of
the steering wheel when driving of-
froad. The steering wheel could jerk
and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim.
IBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
IAlways drive with the floor mats in
place as the floor may become very
hot.
ILower your speed when encounter-
ing strong crosswinds. With its
higher center of gravity, your NISSANis more affected by gusty side winds.
Slower speeds ensure better vehicle
control.
IDo not drive beyond the performance
of the tires even with 4WD.
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
IInstall the same size of winter tires on
all four wheels (such as studless
tires) or install tire chains to the rear
wheels when driving on slippery
roads (for example, after a snow) and
drive carefully using 4WD.
IBe sure to check the brakes immedi-
ately after driving in mud or water.
See ªBrake systemº later in this sec-
tion for wet brakes.
IAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.

sand, mud or water as deep as the
wheel hub, more frequent mainte-

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit develops a problem, you
will still have braking at two wheels.Vacuum assisted brakeThe brake booster aids braking by using en-
gine vacuum. If the engine stops, you can stop
the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
the stopping distance will be longer.Using the brakesAvoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster and
reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, before going down a
slope or long grade, reduce speed and down-
shift to a lower gear.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat-up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake fluid
pressure to prevent each wheel from locking
and sliding. By preventing wheel lockup, the
system helps the driver maintain steering con-
trol and helps to minimize swerving and spin-ning on slippery surfaces.
Using the systemDepress the brake pedal and hold it down.Do not pump the brake pedal. Doing so
may result in increased stopping
distances.Normal operationThe anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more
wheels are close to locking up, the actuator
(under the hood) rapidly applies and releases
hydraulic pressure (like pumping the brakes
very quickly). While the actuator is working,
you may feel a pulsation in the brake pedal
and hear a noise or vibration from the actuator
under the hood. This is normal and indicates
that the anti-lock system is working properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.

IAutomatic transmission models can-
not be push started. This may cause
transmission damage.
IThree way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
INever try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
If your vehicle is overheating indicated by an
extremely high temperature gauge reading, or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
IDo not open the hood if steam is
coming out.1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (automatic
transmission to P (Park)).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to maximum hotand fan control to high speed.
3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the cooling fan belt is missing or loose or
the cooling fan does not run, stop the
engine.
