Active Drive Control — If Equipped
The Power Transfer Unit (PTU) is locked to ensure
immediate availability of torque to the rear drive
axles. This feature is selectable in AUTO mode and
automatic in the other driving mode. 4WD LOCK
can be enabled by the following ways:
When the 4WD LOCK button is pushed.
When the Selec-Terrain switch is moved from
AUTO to any other off-road modes.
Active Drive With Low Control — (Trailhawk models
only)
The 4WD LOW mode helps to improve the off-road
performance in all modes. To enable 4WD LOW,
please follow the steps below:
Enabling 4WD LOW
With the vehicle stationary, the ignition in the ON/
RUN position or with the engine running, shift the
transmission into NEUTRAL and push the 4WD
LOW button once. The instrument cluster will
display the message “4WD LOW” once the shift is
complete.
NOTE:
Both LOCK and LOW LED lights will blink and
then become active on the buttons until the
shift is complete.
The instrument cluster display will illuminate the
4WD LOW icon. Disabling 4WD LOW
To disable the 4WD LOW mode, the vehicle must
be stationary and the transmission shifted into
NEUTRAL. Push the 4WD LOW button once.
SELEC-TERRAIN — IF EQUIPPED
Selec-Terrain combines the capabilities of the
vehicle control systems, along with driver input, to
provide the best performance for all terrains.
MODE SELECTION GUIDE

Selec-Terrain Switch

AUTO
: This four-wheel drive operation is a
continuous operation, is fully automatic and can
be used on and off road. This mode balances
traction to ensure maneuverability and acceler -
ation improvement compared to a vehicle with
two wheel drive. This mode also reduces fuel consumption, since it allows the disconnect of
the drive shaft where conditions permit.
SNOW
: This mode allows you to have greater
stability under conditions of bad weather. For
use on and off road on surfaces with poor trac-
tion, such as roads covered with snow. When in
SNOW mode (depending on certain operating
conditions), the transmission may use SECOND
gear (rather than FIRST gear) during launches,
to minimize wheel slippage.
SAND/MUD : For off-road driving or use on
surfaces with poor traction, such as dry sand
and roads covered by mud or wet grass. The
transmission is set to provide maximum trac -
tion.
ROCK : (Trailhawk only): This mode is only avail -
able in 4WD LOW range. The device sets the
vehicle to maximize traction and allow the
highest steering capacity for off-road surfaces.
This mode gives you the maximum performance
off-road. Use for low speed obstacles such as
large rocks, deep ruts, etc.
SPORT : This mode is only available in 4WD
AUTO, and alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of avail -
able engine power. Suspension settings are
optimized and steering assist is modified to
provide better handling performance.

NOTE:
ROCK mode is only available on the vehicles
equipped with the Off-Road package.
Activate the Hill Descent Control for steep down -
hill control Ú page 188.
POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The electric power steering
system adapts to different driving conditions.
If the “SERVICE POWER STEERING” or “POWER
STEERING ASSIST OFF - SERVICE SYSTEM”
message and a steering wheel icon are displayed
on the instrument cluster display, it indicates that
the vehicle needs to be taken to an authorized
dealer for service. It is likely the vehicle has lost
power steering assistance Ú page 77.If the “POWER STEERING SYSTEM HOT -
PERFORMANCE MAY BE LIMITED” message and an
icon are displayed on the instrument cluster
display, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the electric power
steering system. You will lose power steering
assistance momentarily until the over temperature
condition no longer exists. Once driving conditions
are safe, pull over and let the vehicle idle for a few
moments until the light turns off Ú
page 77.
NOTE:
Even if the power steering system is no longer
operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or
pressing the accelerator pedal will automatically
restart the engine. This vehicle has been upgraded with a heavy-duty
starter, enhanced battery, and other upgraded
engine parts, to handle the additional engine
starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START READY
state. A “STOP/START READY” message will be
displayed in the instrument cluster display
within the Stop/Start section Ú
page 77.
The vehicle must be completely stopped.
The gear selector must be in a forward gear and
the brake pedal pressed.
The engine will shut down, the tachometer will
move to the zero position, and the Stop/Start
telltale will illuminate indicating you are in
Autostop. Customer settings will be maintained
upon return to an engine-running condition.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

appear in the instrument cluster display
Ú page 77.
If the “SERVICE STOP/START SYSTEM” message
appears in the instrument cluster display, have the
system checked by an authorized dealer.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.

22_MP_OM_EN_USC_t.book Page 116

118STARTING AND OPERATING
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, or pushing the CANC
button, or normal brake pressure will deactivate
the Cruise Control system without erasing the set
speed from memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in
the OFF position, will erase the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently if your vehicle is not equipped
with ACC Ú page 117.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 328.
WARNING!

Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.

22_MP_OM_EN_USC_t.book Page 118

122STARTING AND OPERATING
To Resume
If there is a set speed in memory, push the RES
(resume) button and remove your foot from the
accelerator pedal. The instrument cluster display
will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
NOTE:
If your vehicle is at standstill longer than two
seconds, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the Adaptive Cruise Control
(ACC) to the existing set speed
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system decelerates the vehicle to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the
existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.

the nozzle.
5. Remove the fuel nozzle and close the fuel door.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar. This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN).
A Month-Day-Hour (MDH) number is included on
this label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)

The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear Gross Axle
Weight Rating (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.

Payload
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire
size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc
-
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

STARTING AND OPERATING155
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle. These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control and
a Weight-Distributing (load equalizing) Hitch are recommended for heavier Tongue Weights (TW)
and may be required depending on vehicle and
trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
TRAILER TOWING WEIGHTS (MAXIMUM TRAILER WEIGHT RATINGS)
WARNING!
An improperly adjusted Weight-Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-Distributing systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.
