selected gear until another upshift or downshift
is chosen, except as described below:
•The transmission will automatically upshift
when necessary to prevent engine over-
speed.
•The transmission will automatically downshift
as the vehicle slows (to prevent engine lug-
ging) and will display the current gear.
•The transmission will automatically downshift
to first gear when coming to a stop. After a
stop, the driver should manually upshift (+)
the transmission as the vehicle is
accelerated.
•If a requested downshift would cause the
engine to overspeed, that shift will not occur.
•Transmission shifting will be more noticeable
when AutoStick is engaged.
•Heavy Anti-Lock Brake System (ABS) appli-
cation will disengage AutoStick mode.
•The system may revert to automatic shift
mode if a fault or overheat condition is
detected.To disengage AutoStick mode, hold the gear
selector to the right (+) until “D” is once again
displayed in the instrument cluster. You can shift
in or out of the AutoStick mode at any time
without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
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 additional 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 allow-
ing 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.

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 applica-
tions. Specific design characteristics give them
a higher center of gravity than ordinary vehicles.
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 sat-
isfactorily in off-road conditions. If at all pos-
sible, 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. Con-
trolling your vehicle is one of the keys to suc-
cessful 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 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.
179

This will allow you to cross over obstacles and
descend hills, with improved control and less
effort.
NOTE:
For maximum off-road performance, pre-
mium fuel is recommended. While the ve-
hicle 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 SandThere 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 acceler-
ate 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 head-way. 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"bite"and help maintain your
momentum.
CAUTION!
On icy or slippery roads, do not downshift at
high engine RPM’s or vehicle speeds be-
cause engine braking 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 in-
creased threat of vehicle damage and getting
stuck. They are normally full of debris fromprevious vehicles getting stuck. As a good prac-
tice 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 recov-
ered 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 momen-
tum and do not stop. The key to driving in soft
sand is using the appropriate tire pressure,
accelerating slowly, avoiding abrupt maneuvers
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 mini-
mum 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 LOCK en-
gaged and ESC turned off. Reduced tire pres-
sure will drastically improve your traction and
handling, while driving on the soft sand, but you
must return the tires to normal air pressure
before driving on pavement or other hard sur-
faces. Be sure you have a way to reinflate the
tires prior to reducing the pressure.
180

CAUTION!
Reduced tire pressures may cause tire un-
seating and total loss of air pressure. To
reduce the risk of tire unseating, while at a
reduced tire pressure, reduce your speed
and avoid sharp turns or abrupt maneuvers.
Hill ClimbingHill climbing requires good judgment and a
good understanding of your abilities and your
vehicle’s limitations. Hills can cause serious
problems. Some are just too steep to climb and
should not be attempted. You should always
feel confident with the vehicle and your abilities.
You should always climb hills straight up and
down. Never attempt to climb a hill on an angle.
Before Climbing A Steep Hill
As you approach a hill consider its grade or
steepness. Determine if it is too steep. Look to
see what the traction 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 goeswrong? If everything looks good and you feel
confident, then you should use low (L Off-Road
[if equipped]) with the 4WD LOCK engaged and
proceed with caution maintaining your momen-
tum as you climb the hill.
Driving Up Hill
Once you have determined your ability to pro-
ceed 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 accel-
erator and maintain headway by turning the
steering wheel no more than a 1/4 turn quickly
back and forth. This will provide a fresh"bite"
into 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 RE-VERSE 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 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.
181

WARNING!
Do not descend a steep grade in NEUTRAL.
Use vehicle brakes in conjunction with en-
gine 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 pos-
sibilities 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 cometo 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 WaterExtreme 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 abilities 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 with a constant slow
speed (3-5 mph [5–8 km/h] maximum) and light
throttle. Keep the vehicle moving; do not try to
accelerate through the crossing. After crossing
any water higher than the bottom of the axle
differentials, you should inspect all of the ve-
hicle fluids for signs of water ingestion.
CAUTION!
Water ingestion into the transaxle, transfer
case, engine or vehicle interior can occur if
you drive too fast or through too deep of
