the approximate average fuel
economy that the vehicle has right
now, and will change as driving
conditions change. The Average
Fuel Economy can be reset by
pressing and holding
Vwhile this
display is active.
The Average Speed display shows
the average speed of the vehicle in
kilometers per hour (km/h) or miles
per hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value. The average
speed can be reset by pressing and
holding
Vwhile this display is
active.
Fuel Range and Instantaneous
Fuel Economy : Displays the
approximate distance the vehicle
can be driven without refueling.
LOW will be displayed when the
vehicle is low on fuel. The fuel
range estimate is based on an
average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. Displays the current fuel economy in
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number reflects only the
approximate fuel economy that the
vehicle has right now and changes
frequently as driving conditions
change.
Oil Life :
Displays an estimate of
the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil0250.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See Maintenance
Schedule 0323.

Driving Information
Driver Behavior
Driving is an important
responsibility. Driver behavior, the
driving environment, and the
vehicle's design all affect how well a
vehicle performs.
Being aware of these factors can
help in understanding how the
vehicle handles and what can be
done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced
or prevented by the use of seat
belts. In a rollover crash, an
unbelted person is significantly
more likely to die than a person
wearing a seat belt. In addition,
avoiding excessive speed, sudden
or abrupt turns, and drunken or
aggressive driving can help make
trips safer and avoid the possibility
of a crash.
Driving Environment
Be prepared for driving in inclement
weather, at night, or during other
times where visibility or traction may
be limited, such as on curves,
slippery roads, or hilly terrain.
Unfamiliar surroundings can also
have hidden hazards.
Vehicle Design
Utility vehicles have a significantly
higher rollover rate than other types
of vehicles. This is because they
have a higher ground clearance and
a narrower track or shorter
wheelbase than passenger cars,
which makes them more capable for
off-road driving. While these design
characteristics provide the driver
with a better view of the road, these
vehicles do have a higher center of
gravity than other types of vehicles.
A utility vehicle does not handle the
same as a vehicle with a lower
center of gravity, like a car, in similar
situations.

Driving and Operating 183
.The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
See Antilock Brake System
(ABS) 0200.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0343. To get
help and keep everyone in the
vehicle safe: .
Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
(Continued)
Warning (Continued)
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See “Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0196.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.

Example 3
1.Vehicle Capacity Weight
for Example 3 = 453 kg
(1,000 lbs).
2.Subtract Occupant
Weight @ 91 kg
(200 lbs) × 5 = 453 kg
(1,000 lbs).
3.Available Cargo Weight
= 0 kg (0 lbs).
Refer to the vehicle's tire and
loading information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined weight of the driver, passengers,
and cargo should never exceed
the vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/
Tire label is attached to the
center pillar (B-pillar).
The label may show the size of
the vehicle's original tires and
the inflation pressures needed to
obtain the gross weight capacity
of the vehicle. The label shows
the gross weight capacity of the
vehicle. This is called the GrossVehicle Weight Rating (GVWR).
The GVWR includes the weight
of the vehicle, all occupants,
fuel, and cargo.
The Certification/Tire label may
also show the maximum weights
for the front and rear axles,
called the Gross Axle Weight
Rating (GAWR). To find out the
actual loads on the front and
rear axles, weigh the vehicle at
a weigh station. Your dealer can
help with this. Be sure to spread
the load equally on both sides of
the centerline.
CautionOverloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
