Recreational Towing — Front-Wheel Drive (FWD)
Models
DO NOTflat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for front-wheel drive models) is al-
lowed ONLY if the front wheels are OFFthe ground. This
may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer’s instructions.
2. Drive the front wheels onto the tow dolly.
3. Apply the parking brake. Place the transmission in PARK. Turn the engine OFF.
4. Properly secure the front wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition to the ON/RUN position, but do not start the engine.
6. Press and hold the brake pedal. 7. Release the parking brake.
8. Turn the ignition OFF, remove the key fob, and release
the brake pedal.
CAUTION!
•Towing with the front wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.

CAUTION!(Continued)
•Ensure that the Electric Park Brake is released, and
remains released, while being towed.
• Do not use a bumper-mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.
Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
Use the following procedure to shift the 4WD system into
NEUTRAL (N).
CAUTION!
It is necessary to follow these steps to be certain that the
power transfer unit is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop and shift the transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition to the ON/RUN mode, but do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, push and hold the recessed NEUTRAL (N) button (located by the
selector switch) for four seconds. The light behind the N
symbol will blink, indicating shift in progress. The light
will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete.

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.6

Off-Road Driving Tips
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water:
NOTE:When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as a
precaution, and check all fluids afterward. Driving through
water may cause damage that may not be covered by the
New Vehicle Limited Warranty.
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle. If you must drive through
water, try to determine the depth and the bottom condition
(and location of any obstacles) prior to entering. Proceed
with caution and maintain a steady controlled speed less
than 5 mph (8 km/h) in deep water to minimize wave
effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off)
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing-water,
avoid depths in excess of 9 inches (22 cm). The flowing water can erode the streambed causing your vehicle to sink
into deeper water. Determine exit point(s) that are down-
stream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 16 inches
(40.5 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 16 inches (40.5 cm) of
water is less than 5 mph (8 km/h).
(Trailhawk only): Avoid driving in standing water deeper
than 19 inches (48 cm), and reduce speed appropriately to
minimize wave effects. Maximum speed in 19 inches (48
cm) of water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Transfer
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.
386 STARTING AND OPERATING

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 because
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.
NOTE: Brakes should be applied at increased slippage, but
before coming to a stop to avoid digging into the loose
surface and rendering the operator of the vehicle stuck/
immobile. 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 brakes. Once stopped, shift to
REVERSE. Back slowly down the hill allowing the com-
pression 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.
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.
NOTE: 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 may provide traction to
complete the climb.6
STARTING AND OPERATING 387

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 toSafety Featuresin the “Safety” section
for further information). Let the vehicle go slowly down
the hill with all four wheels turning against engine com-
pression drag. This will permit 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 transmission
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.
• 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 braking system
may cause excessive wear or unpredictable braking
performance. Full braking power may not be available
to prevent a collision. If you have been operating your
vehicle in dirty conditions, inspect and clean the
braking components as soon as possible.
• Impacted material can cause wheel imbalance. Freeing
the wheels of impacted material will likely rectify im-
balance condition.
