WARNING!
If the Gross Trailer Weight (GTW) is 3,500 lbs (1 587 kg)
or more, it is mandatory to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles evenly.
Make sure that you do not exceed either front or rear GAWR.
Refer to “Vehicle Loading/Vehicle Certification Label” in
“Starting And Operating” for further information.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable friction
associated with the telescoping motion to dampen any
unwanted trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control (TSC)
recognizes a swaying trailer and automatically applies
individual wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of

WARNING!(Continued)
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure, or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross
the chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or chockthe trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
CAUTION!
• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.

DRIVING TIPS
On-Road Driving Tips
Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional passenger cars.
An advantage of the 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 passenger cars any more than low-slung
sports cars are designed to perform satisfactorily in off-
road conditions. 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.
Off-Road Driving Tips
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard packed dirt, gravel, rocks, grass, sand, mud, snow
and ice. Every surface has a different effect on your
vehicle’s steering, handling and traction. Controlling yourvehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and maintain
a good driving posture. Avoid sudden accelerations, turns
or braking. In most cases there are no road signs, posted
speed limits or signal lights. Therefore you will need to use
your own good judgment on what is safe and what is not.
When on a trail, you should always be looking ahead for
surface obstacles and changes in terrain. The key is to plan
your future driving route while remembering what you are
currently driving over.
CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
236 STARTING AND OPERATING

When To Use Low (L Off-Road) With The 4WD Lock
Lever Engaged — If Equipped
When driving off-road, shift into low (L Off-Road [if
equipped] ) and activate the 4WD LOCK. This will provide
additional traction and activates the numerous off-road
features to improve handling and control on slippery or
difficult terrain. Due to the sustained lower gearing, low (L
Off-Road [if equipped] ) with 4WD LOCK engaged will
allow the engine to operate in a higher power range. This
will allow you to cross over obstacles and descend hills,
with improved control and less effort.
NOTE:For maximum off-road performance, premium
fuel is recommended. While the vehicle will operate on
regular fuel when in L Off-Road mode (if equipped), the
engine has been calibrated for maximum performance
using premium fuel.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore, you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum. Snow
In heavy snow or for additional control and traction at
slower speeds, activate the 4WD LOCK and shift the
transaxle to low (L Off-Road [if equipped] ) if necessary. Do
not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the wheels and
traction will be lost. If you start to slow to a stop, try
turning your steering wheel no more than a 1/4 turn
quickly back and forth, while still applying throttle. This
will allow the tires to get a fresh
biteand help maintain
your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM’s or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
Mud
Deep mud creates a great deal of suction around the tires and
is very difficult to get through. You should use low
(L Off-Road [if equipped] ) with the 4WD LOCK engaged
and maintain your momentum. If you start to slow to a stop,
try turning your steering wheel no more than a 1/4 turn
quickly back and forth for additional traction. Mud holes

low (L Off-Road [if equipped]) with the 4WD LOCK
engaged and proceed with caution maintaining your mo-
mentum as you climb the hill.
Driving Up Hill
Once you have determined your ability to proceed and
have shifted into the appropriate gear, line your vehicle up
for the straightest possible run. Accelerate with an easy
constant throttle and apply more power as you start up the
hill. Do not race forward into a steep grade; the abrupt
change of grade could cause you to lose control. If the front
end begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the crest
of the hill, ease off the throttle and slowly proceed over the
top. If the wheels start to slip as you approach the crest of
a hill, ease off the accelerator and maintain headway by
turning the steering wheel no more than a 1/4 turn quickly
back and forth. This will provide a freshbiteinto the
surface and will usually provide enough traction to com-
plete the climb. If you do not make it to the top, place the
vehicle in REVERSE and back straight down the grade
using engine resistance along with the vehicle brakes.WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a rollover, which may result in severe injury.
Driving Down Hill
Before driving down a steep hill you need to determine if
it is too steep for a safe descent. What is the surface
traction? Is the grade too steep to maintain a slow con-
trolled descent? Are there obstacles? Is it a straight descent?
Is there plenty of distance at the base of the hill to regain
control if the vehicle descends to fast? If you feel confident
in your ability to proceed then make sure you are in low (L
Off-Road [if equipped] ) with the 4WD LOCK engaged and
proceed with caution. Allow engine and hill descent brak-
ing to control the descent and apply your brakes if neces-
sary, but do not allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.

STARTING AND OPERATING 239

Driving Across An Incline
If at all possible avoid driving across an incline. If it is
necessary, know your vehicle’s abilities. Driving across an
incline places more weight on the down-hill wheels, which
increases the possibilities of a down-hill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll-
over, which may result in severe injury.
If You Stall Or Begin To Lose Headway
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift to REVERSE.
Back slowly down the hill allowing engine and hill descent
braking to control the descent and apply your brakes if
necessary, but do not allow the tires to lock.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle, which may result in severe injury.
Always back carefully straight down a hill in RE-
VERSE gear. Never back down a hill in NEUTRAL
using only the vehicle brakes. Never drive diagonally
across a hill, always drive straight up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and only be
attempted when necessary in a safe responsible manner.
You should only drive through areas which are designated
and approved. You should tread lightly and avoid damage
to the environment. You should know your vehicles abili-
ties and be able to recover it if something goes wrong. You
should never stop or shut a vehicle off when crossing deep
water unless you ingested water into the engine air intake.
If the engine stalls, do not attempt to restart it. Determine
if it has ingested water first. The key to any crossing is low
and slow. You want to use low (L Off-Road [if equipped] )
with the 4WD LOCK engaged and proceed very slowly
240 STARTING AND OPERATING

always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.

CAUTION!
•When installing the IPM cover, it is important to
ensure the cover is properly positioned and fully
latched. Failure to do so may allow water to get into
the IPM, and possibly result in an electrical system
failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
JACKING AND TIRE CHANGING
WARNING!
•Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.
• Never start or run the engine while the vehicle is on
a jack.
• The jack is designed to be used as a tool for changing
tires only. The jack should not be used to lift the
