The trailer brake control interacts with the instrument
cluster display. Display messages, along with a single
chime, will be displayed when a malfunction is determined
in the trailer connection, trailer brake control, or on the
trailer
Úpage 99.
NOTE:
An aftermarket controller may be available for use with
trailers with air or EOH trailer brake systems. To deter -
mine the type of brakes on your trailer and the avail -
ability of controllers, check with your trailer
manufacturer or dealer.
Removal of the ITBM will cause errors and it may cause
damage to the electrical system and electronic
modules of the vehicle. See an authorized dealer if an
aftermarket module is to be installed.
Towing Requirements — Trailer Lights
And Wiring
Whenever pulling a trailer, regardless of the trailer size,
stop lights 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 the trailer wiring connector from the vehicle
(or any other device plugged into the vehicle's electrical
connectors) before launching a boat into water.
Be sure to reconnect once clear from water area.
Four-Pin Connector
WARNING!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
personal injury.
CAUTION!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
damage to your vehicle, trailer, or other property.

TOWING TIPS
Before towing, practice turning, stopping, and backing up
the trailer in an area located away from heavy traffic. If
equipped with Quadra-Lift air suspension, the automatic
Entry/Exit feature may be disabled through the Uconnect
Touchscreen Radio to prevent vehicle and trailer
movement when gear selector is moved to PARK.
Automatic Transmission
Select the DRIVE (D) range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the Electronic Range Select
(ERS) shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle under heavy
loading conditions, will improve performance and extend
transmission life by reducing excessive shifting and heat
build-up. This action will also provide better engine
braking.
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.

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.

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 stop. The 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 Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
WARNING!
The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting 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 hydroplaning.
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.
WARNING!

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.

ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is placed in the ON/RUN mode. It
should go out with the engine running. If the
ESC Activation/Malfunction Indicator Light comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected. The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN mode.
Each time the ignition is placed in the ON/RUN mode,
the ESC system will be on even if it was turned off previ -
ously.
The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road driving
while in 4WD Low. HDC maintains vehicle
speed while descending hills during various
driving situations. HDC controls vehicle speed
by actively controlling the brakes. HDC Has Three States:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
The driveline is in 4WD Low.
The vehicle speed is below 5 mph (8 km/h).
The parking brake is released.
The driver door is closed.
Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by
using the gear shift +/-. The following summarizes the
HDC set speeds:
WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC, except for the limited slip feature described in
the TCS section, has been disabled and the ESC OFF
Indicator Light will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.

7th = 4.3 mph (7 km/h)
8th = 5.0 mph (8 km/h)
9th = 5.6 mph (9 km/h) – If Equipped
NOTE:During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the trans -
mission will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if any of the
following conditions occur:
The driver overrides HDC set speed with throttle or
brake application.
The vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h).
The vehicle is on a downhill grade of insufficient magni -
tude, is on level ground, or is on an uphill grade.
The vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
The driver pushes the HDC switch.
The driveline is shifted out of 4WD Low.
The parking brake is applied.
The driver door opens.
The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
The vehicle is driven greater than 40 mph (64 km/h)
(HDC exits immediately).
HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC
switch has an LED icon, which offers feedback to the
driver about the state HDC is in.
The cluster icon and switch light will illuminate and
remain on solid when HDC is enabled or activated. This
is the normal operating condition for HDC.
The cluster icon and switch light will flash for several
seconds, then extinguish when the driver pushes the
HDC switch but enable conditions are not met.
The cluster icon and switch light will flash for several
seconds, then extinguish when HDC disables due to
excess speed.
The cluster icon and switch light will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal.
The following conditions must be met in order for HSA to
activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE (R) gear).
HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK (P) or NEUTRAL (N).
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.
