Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction 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 thecluster. 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.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.

STARTING AND OPERATING 301

WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.2. Slow down if the road has standing water or puddles.
3. Replace the tires when tread wear indicators first
become visible.
4. Keep the tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front of you to avoid a collision in a sudden
stop.DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
302 STARTING AND OPERATING

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 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.
5
STARTING AND OPERATING 305

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
When driving off-road, shift into low (L Off-Road) 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 (LOff-Road) 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, the engine has
been calibrated for maximum performance using pre-
mium 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.
306 STARTING AND OPERATING

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 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 freshbiteand help maintain your momen-
tum.
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) 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.

is on the hill side trail. Is the trail straight up and down?
What is on top and the other side? Are there ruts, rocks,
branches or other obstacles on the path? Can you safely
recover the vehicle if something goes wrong? If every-
thing looks good and you feel confident, then you should
use low (L Off-Road) with the 4WD LOCK engaged and
proceed with caution maintaining your momentum 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 asyou 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 fresh
biteinto 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
5
STARTING AND OPERATING 309

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) with the 4WD 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.
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.
310 STARTING AND OPERATING

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 an accident. Have the vehicle checked immedi-
ately.
Anti-Lock Brake System (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically “pumps” the brakes during severe braking
conditions to prevent wheel lock-up.
WARNING!
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.(Continued)
