FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).
Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loosetraction surfaces, activate the “4WD LOCK” switch by
pulling up once and releasing. This locks the center
coupling allowing more torque to be sent to the rear
wheels. The “4WD Indicator Light” will come on in the
cluster. This can be done on the fly, at any vehicle speed.
To deactivate, simply pull on the switch one more time.
The “4WD Indicator Light” will then go out.
NOTE:
Refer to “Electronic Brake Control System/
Electronic Stability Control (ESC)” in “Starting And Op-
erating” for further information.
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
characteristics give them a higher center of gravity than
ordinary 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 two-wheel drive vehicles any more than
low-slung sports cars are designed to perform satisfacto-
rily in off-road 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.
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. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheeland 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
combustible 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.
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
5
STARTING AND OPERATING 363
Page 366 of 589
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 freshbiteand 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 pose an increased threat of vehicle damage and
getting stuck. They are normally full of debris from
previous vehicles getting stuck. As a good practice before
entering any mud hole, get out and determine how deep
it is, if there are any hidden obstacles and if the vehicle
can be safely recovered if stuck.
Sand
Soft sand is very difficult to travel through with full tire
pressure. When crossing soft sandy spots in a trail
maintain your vehicle’s momentum and do not stop. The
key to driving in soft sand is using the appropriate tire
pressure, accelerating slowly, avoiding abrupt maneu-
vers and maintaining the vehicle’s momentum. If you are
going to be driving on large soft sandy areas or dunes,
reduce your tire pressure to a minimum of 15 psi
(103 kPa) to allow for a greater tire surface area. You
should use low (L Off-Road [if equipped] ) with the 4WD
364 STARTING AND OPERATING

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 complete 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
controlled 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
366 STARTING AND OPERATING
Page 369 of 589
LOCK engaged and proceed with caution. Allow engine
and hill descent braking to control the descent and apply
your brakes if necessary, 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.
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
rollover, 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.

If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application and greater
pedal force required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the “Brake Warning
Light” will light.
WARNING!
Driving a vehicle with the “Brake Warning Light” on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have a collision. Have the vehicle checked immedi-
ately.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Your vehicle may also be equipped with Hill Descent
Control (HDC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.

8. Turn the ignition switch to the OFF position and thenback to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial and controls the wheel spin across a driven axle. If
one wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied
to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by the
driver and compares it to the actual path of the vehicle.
When the actual path does not match the intended path,
ESC applies the brake of the appropriate wheel to assist
in counteracting the over-steer or under-steer condition
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
