132STARTING AND OPERATING
Selec-Terrain consists of the following positions:
ROCK (if equipped) – Off-road calibration is only avail -
able in 4WD LOW. The vehicle is raised (if equipped
with Air Suspension) for improved ground clearance.
Traction-based tuning with improved steerability for
use on high traction off-road surfaces. Use for low
speed obstacles such as large rocks, deep ruts, etc. If
equipped with air suspension, the vehicle level will
change to Off-Road 2 (OR2). If the Selec-Terrain switch
is in ROCK mode, and the transfer case is switched
from 4WD LOW to 4WD HI, the Selec-Terrain system
will return to AUTO.
 SAND (if equipped) – Off-road calibration for use on low
traction surfaces such as 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. If equipped with air suspension, the
default ride height for SAND is Normal Ride Height
(NRH).
 MUD (if equipped) – Off-road calibration for use on low
traction surfaces such as mud. 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. If equipped with air suspension, the level will
change to Off-Road 1 (OR1). 
SNOW – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as 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. If equipped with
air suspension, the default ride height for SNOW is
Normal Ride Height (NRH).
 AUTO – Fully automatic full-time four-wheel drive oper -
ation can be used on and off road. Balances traction
with seamless steering feel to provide improved
handling and acceleration over two-wheel drive vehi -
cles. If equipped with air suspension, the level will
change to Normal Ride Height (NRH).
 SPORT – This mode alters the transmission's auto -
matic shift schedule for sportier driving. Upshift speeds
are increased to make full use of available engine
power. Steering efforts are modified for sporty driving.
If equipped with air suspension, the level will change to
Aero Height.

QUADRA-LIFT — IF EQUIPPED
DESCRIPTION
The Quadra-Lift Air Suspension system provides full-time
load leveling capability along with the benefit of vehicle
height adjustment by a toggle switch. The vehicle will automatically raise and lower the ride
height to adapt to the appropriate driving conditions. At
higher speeds, the vehicle will lower to an aerodynamic
ride height and when operating in off-road modes (if
equipped), the vehicle will raise the ride height
accordingly. The buttons near the terrain switch in the
center console area can be used to set preferred ride
height to match the appropriate conditions.

OPERATION
The indicator lamps 1 through 5 will illuminate to show the
current position of the vehicle. Flashing indicator lamps
will show a position which the system is working to
achieve. When raising, if multiple indicator lamps are
flashing while raising, the highest flashing indicator lamp
is the position the system is working to achieve. When
lowering, if multiple indicators are flashing while lowering
the lowest solid indicator lamp is the position the system
is working to achieve.
Toggle up once moves the suspension one position higher
from the current position, assuming all conditions are met
(i.e., engine running, speed below threshold, etc.). Toggle
up can be pushed multiple times. Each toggle up will raise
the requested level by one position up to a maximum
position of OR2 or the highest position allowed based on
current conditions (i.e., vehicle speed, etc.).
Toggle down once moves the suspension one position
lower from the current level, assuming all conditions are
met (i.e., engine running, doors closed, speed below
threshold, etc.). Toggle down can be pushed multiple
times. Each toggle down will lower the requested level by
one position down to a minimum of Park mode or the
lowest position allowed based on current conditions (i.e.,
vehicle speed, etc.) Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and instrument cluster display messages will operate the
same for automatic changes and user requested changes.

FUEL SAVER TECHNOLOGY 5.7L AND 6.4L
ONLY — IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE:This system may take some time to return to full function -
ality after a battery disconnect.
POWER STEERING
The electric power steering system is designed to provide
increased vehicle response and ease of maneuverability
in tight spaces. The power steering system adapts to
different driving conditions. If the electric power steering
system experiences a fault that prevents it from providing
assist, you will still have the ability to steer the vehicle
manually.
NOTE:Alternate electric power steering efforts can be selected
through the Uconnect System Úpage 197.
If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER
STEERING” or the “POWER STEERING ASSIST
OFF – SERVICE SYSTEM” message is displayed
within the instrument cluster display, this indicates the
vehicle needs to be taken to an authorized dealer for
service
Úpage 108.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

136STARTING AND OPERATING
NOTE:
Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is displayed on
the instrument cluster screen, they indicate that extreme
steering maneuvers may have occurred which caused an
over temperature condition in the electric power steering
system. Once driving conditions are safe, pull over and let
the vehicle idle for a few moments until the icon and
message turn off.
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
Úpage 136.
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 and if all other conditions are met,
can go into a STOP/START AUTOSTOP ACTIVE Autostop
mode.
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

COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 178.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 178.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
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 used to tow small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing Hitch 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.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
WARNING!
An improperly adjusted Weight-Distributing Hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
 Weight-Distributing Hitch 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.

Integrated Trailer Brake Module (ITBM)

The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the
tow vehicle's brakes. If the manual brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle's brake lamps will come on
when either vehicle braking or manual trailer brakes are
applied. Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN
setting for 10 seconds and the Trailer Brake Status
Indicator Light will not be displayed.
If a fault is detected in the trailer wiring or the ITBM, the
Trailer Brake Status Indicator Light will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or
decreased to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).

1. Make sure the trailer brakes are in good working condition, functioning normally and properly
adjusted. See a trailer dealer if necessary.

2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's
instructions. 3. When a trailer with electric/EOH brakes is plugged in,
the trailer connected message should appear in the
instrument cluster display (if the connection is not
recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and the
correct type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the “Trailer Brake Type” appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type appears
on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier trailer,
trailer wheel lockup may not be attainable even with the
maximum GAIN setting of 10.

STARTING AND OPERATING195
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and
shift into REVERSE (R). 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.
Remember, never drive diagonally across a hill. Always
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 forward motion
by turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.Traction Downhill
When descending mountains or hills, use Hill Descent
Control or Selec-Speed Control to avoid repeated heavy
braking.
If not equipped with Hill Descent Control or Selec-Speed
Control use the following procedure:
Shift the transmission into a low gear, and the transfer
case into 4WD LOW range. 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. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
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
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.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
WARNING!
If the engine stalls, you lose forward motion, 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 carefully straight down a hill in
REVERSE gear. Never back down a hill in NEUTRAL
using only the brake.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.

SAFETY241
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced EBC system.
This system includes the Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Stability Control (ESC),
Electronic Roll Mitigation (ERM), Hill Start Assist (HSA),
Intersection Collision Assist (ICA), 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), 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.
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.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off” mode (if
equipped). See
Úpage 242 for a complete explanation of
the available ESC modes.
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.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user's safety or the safety of
others.
