158STARTING AND OPERATING
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stoplights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical connect)
into water.
Be sure to reconnect once clear from water
area.
Four-Pin Connector

WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
Select the DRIVE (D) range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. For increased
engine braking on steep downhill grades, select
the LOW range.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.

Recreational towing (with all four wheels on the
ground, or using a towing dolly) is NOT ALLOWED.
This vehicle may be towed on flatbed or vehicle
trailer provided all four wheels are OFF the ground.
DRIVING TIPS
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 conventional
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.
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
Ú page 112. This range should be limited to extreme situations 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.
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:
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent 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.
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.
Do not use a bumper mounted clamp-on tow
bar on your vehicle. The fascia/bumper face
will be damaged.
CAUTION!
Towing this vehicle with ANY of its wheels on the
ground can cause severe transmission and/or
power transfer unit damage. Damage from
improper towing is not covered under the
New Vehicle Limited Warranty.
CAUTION!
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.

162STARTING AND OPERATING
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 downstream
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
ensure 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 Úpage 112. 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 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.
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.
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.

22_MP_OM_EN_USC_t.book Page 162

STARTING AND OPERATING163
Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or select Hill Descent
Control (if equipped) Úpage 191. Let the vehicle
go slowly down the hill with all four wheels turning
against engine compression 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, partic -
ularly on the chassis, drivetrain components,
steering, and suspension. 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.
Impacted material can cause wheel imbalance.
Freeing the wheels of impacted material will
likely rectify imbalance condition.
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.

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and
brake performance under most braking conditions.
The system automatically prevents wheel lock and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that
the ABS is working properly each time the vehicle
is started and driven. During this self-check, you
may hear a slight clicking sound as well as some
related motor noises.
The ABS is activated during braking when the
system detects one or more wheels are beginning
to lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic stops
may increase the likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stopThe ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may
stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on
while driving, it indicates that the anti-lock portion
of the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of Anti-lock Brakes. If the ABS Warning
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer
-
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
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
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro -
planing.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.

soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM

Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake Assist
System (BAS), Electronic Brake Force Distribution
(EBD), Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), Hill Start Assist (HSA), and
Traction Control System (TCS). These systems work
together to enhance both vehicle stability and
control in various driving conditions.

Your vehicle may also be equipped with Dynamic
Steering Torque (DST), Hill Descent Control (HDC),
Rain Brake Support (RBS), Ready Alert Braking
(RAB), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To receive the benefit of the system, you must
apply continuous braking pressure during the
stopping sequence (do not “pump” the brakes). Do
not reduce brake pedal pressure unless braking is
no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or
comes on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the Electronic Stability Control
(ESC) and Electric Power Steering (EPS) modules
that provides torque at the steering wheel for
certain driving conditions in which the ESC module
is detecting vehicle instability. The torque that the
steering wheel receives is only meant to help the
driver realize optimal steering behavior in order to
reach/maintain vehicle stability. The only
notification the driver receives that the feature is
active is the torque applied to the steering wheel.
NOTE:The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly
dependent on the driver’s sensitivity and overall
reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.
Electronic Brake Force Distribution (EBD)
EBD 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.
WARNING!

The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by
prevailing road conditions. BAS cannot prevent
collisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a BAS-equipped
vehicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the
user's safety or the safety of others.
