Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or
inf ormation on adding the proper
coolant. Always maintain your vehicle
according to the maintenance
schedule. See
(see page
). Try to maintain a constant speed.
Everytimeyouslowdownand
speed up, your vehicle uses extra
f uel. Use cruise control when
appropriate.
Combine several short trips into
one.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Usethefresh-air
ventilation when possible.
The build-up of snow or mud on
your vehicle’s underside adds
weight and rolling resistance.
Frequent cleaning helps your f uel
mileage and reduces the chance of
corrosion.
Drive moderately. Rapid
acceleration, abrupt cornering,
and hard braking use more f uel.
Always drive in the highest gear
possible. an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses more f uel.

Your vehicle has higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier.
Because your vehicle rides higher
of f the ground, it has a high center
of gravity that can cause it to roll
over if you make abrupt turns. Utility
vehicles have a signif icantly higher
roll over rate than other types of
vehicles.
To prevent rollovers or loss of
control:Take corners at slower speeds
than you would with a passenger
vehicle.
Avoid sharp turns and abrupt
maneuvers whenever possible. Do not modif y your vehicle in any
way that would raise the center of
gravity.
Do not carry heavy cargo on the
roof .
Youshoulddothefollowingchecks
and adjustments bef ore you drive
your vehicle. Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice. Make sure the doors and tailgate
are securely closed and locked. Check the steering wheel
adjustment (see page ). Check the adjustment of the
inside and outside mirrors (see
page ). Check the seat adjustment (see
page ). Check that any items you may be
carrying are stored properly or
f astened down securely.
When you start the engine, check
the gauges and indicators in the
instrument panel (see page ).
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure. Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).

Set the parking brake.
Make sure the ignition switch is in
the LOCK (0) position.
To release the Reverse Lockout,
make sure the ignition switch is in
the ACCESSORY (I) position. Put a cloth on the edge of the Shif tLock Release slot cover. Using a
key, caref ully pry on the edge of
the cover to remove it.
Insert the key in the shift lock
release slot.
Push down on the key and move
the shift lever out of Park to
Neutral.To release the reverse lockout,
move the shift lever from neutral
to reverse, then to Park.
Do this if pushing on the brake pedal
does not shif t the transmission out of
Park. This procedure is also used to
release the Reverse Lockout.
Remove the key from the Shift
Lock Release slot. Press the brake
pedal and restart the engine.
If you need to use the shif t lock
release, it means your vehicle is
developing a problem. Have it
checked by your dealer.

Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator and the
appropriate tire on the tire pressure
monitor to come on. Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.When this indicator is on, one or
more of your tires is signif icantly
under inf lated. You should stop and
check your tires as soon as possible.Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Although your tire pressure is
monitored, each tire should be
checked monthly, including the
spare.
Check the pressure with the tires
cold, af ter the vehicle has been
parked f or at least 2 hours.
Set to the recommended inf lation
pressure as specif ied on the vehicle
placard and in this owner’s manual
(see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you. Braking System DesignBrake Wear Indicators

Your vehicle has been designed to
primarily carry passengers and their
cargo. You can also use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The weight that the tongue of a f ully
loaded trailer puts on the hitch
shouldbe5to10percentof thetotal
trailer weight f or boat trailers, and 8
to 15 percent of total trailer weight
f or all other trailers. (See pagef or limits f or your towing
situation). Too much tongue load
reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.
The maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
inyourvehicleandthetypeof trailer
being towed (see page ).
Towing a trailer that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and driven.
Be sure to read the
sectiononpage
if you plan to tow of f paved
surf aces.

Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
beforestartingtodrive.

Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
f or any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
caref ully inspect your vehicle to
make sure there is no damage that
could make driving it unsaf e.
Recheck the condition of the tires
and the tire pressures.
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take the proper
precautions.Forbettertractiononallsurfaces,
accelerate slowly and gradually build
up speed. If you try to start too fast
on wet soil, mud, snow, or ice, you
might not have enough traction to
get underway, and you may dig
yourself a hole. Starting with the
shif t lever in second (2) gear will
help you have a smoother start on
snow or ice.
Keep in mind that you will usually
need more time and distance to
brake to a stop on unpaved surf aces.
Avoid hard braking. Do not ‘‘pump’’
the brakes; let the anti-lock braking
system pump them f or you.
Debris in the road can damage your
suspension or other components.
Because your vehicle has a high
center of gravity, driving over a large
obstacle, or allowing a wheel to drop
into a deep hole can cause yourvehicle to tip or roll over.
If you can’t clearly see all conditions
or obstacles on a slope, walk the
slope bef ore you drive on it. If you
have any doubt whether or not you
can saf ely drive on the slope, don’t
do it. Find another route.
The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components.
If you are driving up a hill and f ind
that you cannot continue,
. Your vehicle could roll
over. Slowly back down the hill,
f ollowing the same route you took up
the hill.
Bef ore driving through water, stop,
get out if necessary, and make sure
that:
do not try to
turn around
