•When enabled the system operates above 37 mph
(60 km/h) and below 112 mph (180 km/h).
•Use of the turn signal suppresses the warnings.
•The system will not apply torque to the steering wheel
whenever a safety system engages. (anti-lock brakes,
traction control system, electronic stability control,
forward collision warning, etc.).
PARKSENSE® REAR PARK ASSIST — IF
EQUIPPED
The ParkSense® Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense® System
Usage Precautions for limitations of this system and
recommendations.
ParkSense® will retain the last system state (enabled or

STARTING AND OPERATING 469

Selec-Terrain™ offers the following modes:
•Auto— Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles.
•Snow— Tuning set for additional stability in inclem-
ent weather. Use on and off road on loose traction
surfaces such as snow. When in SNOW mode (depend-
ing on certain operating conditions), the transmission
may use second gear (rather than first gear) during
launches, to minimize wheel slippage.
•Sport— This mode alters the transmission’s automatic
shift schedule for sportier driving. Upshift speeds are
increased to make full use of available engine power.
NOTE:SPORT mode is not available when 4WD LOW is
selected.
•Sand/Mud— Off road calibration for use on low
traction surfaces such as mud, sand, or wet grass.
Driveline is maximized for traction. Some binding may
be felt on less forgiving surfaces. The electronic brake
controls are set to limit traction control management of
throttle and wheel spin.
•Rock— Off-road calibration only available in 4WD
LOW range. Traction based tuning with improved
steer-ability for use on high traction off-road surfaces.
Use for low speed obstacles such as large rocks, deep
ruts, etc.
NOTE:
•Rock mode is only available on the vehicles equipped
with the Off-Road package.
•Activate the Hill Descent Control or Selec Speed Control
for steep downhill control. See “Electronic Brake Control
System” in this section for further information.

Electronic Vehicle Information Center
(EVIC)/Driver Information Display (DID) Display
Messages
When the appropriate conditions exist, a message will
appear in the EVIC/DID display. Refer to “Electronic
Vehicle Information Center (EVIC)/Driver Information
Display (DID)” in “Understanding Your Instrument
Panel” 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
When To Use 4WD LOW Range
When off-road driving, shift to 4WD LOW for additional
traction and control on slippery or difficult terrain,
ascending or descending steep hills, and to increase
low-speed pulling power (refer to “All Wheel Drive and
Four-Wheel Drive Operation” in this section for further
details). This range should be limited to extreme situa-
tions such as deep snow, mud, or sand where additional
low speed pulling power is needed. Vehicle speeds in
excess of 25 mph (40 km/h) should be avoided when in
4WD LOW range.

STARTING AND OPERATING 505

Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have not
been contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Operating” for
further information. 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.
Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill,shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.

STARTING AND OPERATING 507

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. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill - drive
straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or Select Hill Descent
Control if equipped (refer to#Electronic Brake Control
System#in this section for further information). Let the
vehicle go slowly down the hill with all four wheels
turning against engine compression drag. This will per-
mit you to control the vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
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.
