Integrated Trailer Brake Module — If
Equipped
Your vehicle may have an Integrated Trailer
Brake Module (ITBM) for Electric and Electric
Over Hydraulic (EOH) trailer brakes.
NOTE:
This module has been designed and verified
with electric trailer brakes and new EOH
systems. Some previous EOH systems may not
be compatible with ITBM.

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 stop lamps will
come on when braking normally with the vehicle
brake pedal. Only the trailer stop lamps will
come on when the manual brake control lever is
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.

WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over
-
load 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 stop -
ping 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 lbs
(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 setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control). NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) 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.
Six-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades
at low speeds (20 mph [32 km/h] or below),
holding your vehicle in FIRST gear (using the
ERS shift control) can help to avoid
transmission overheating.
If you regularly tow a trailer for more than
45 minutes of continuous operation, then
change the automatic transmission fluid and
filter(s) as specified for "police, taxi, fleet, or
frequent trailer towing." Ú
page 354.
NOTE:
Check the automatic transmission fluid level
before towing (Six-speed automatic only).

216STARTING AND OPERATING
Shifting Into N (Neutral)
Use the following procedure to prepare your
vehicle for recreational towing.
1. Bring the vehicle to a complete stop on
level ground, with the engine running.
Firmly apply the parking brake.

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Shift the transfer case into N (Neutral):
With manual shift transfer case, shift the
transfer case lever into N (Neutral).

With electronically shifted transfer
case, push and hold the transfer case
N (Neutral) button. Some models have a
small, recessed "N" button (at the center
of the transfer case switches) that must be
pressed using a ballpoint pen or similar
object. Other models have a rectangular
N (Neutral) switch, below the rotary
transfer case control knob. The N (Neutral)
indicator light will blink while the shift is in progress. The light will stop blinking (stay
on solid) when the shift to N (Neutral) is
complete. After the shift is completed and
the N (Neutral) light stays on, release the
N (Neutral) button.

5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle
movement.
8. Repeat steps 6 and 7 with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn off the engine.
For vehicles with Keyless Enter-N-Go, push
and hold the ENGINE START/STOP button
until the engine shuts off.
10. Shift the transmission into PARK.
11. Place the ignition in the OFF mode, and remove the key fob.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake.
Do not disconnect the rear driveshaft
because fluid will leak from the transfer
case, causing damage to internal parts.
Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper face
bar will be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (NEUTRAL) position without first
fully engaging the parking brake. The transfer
case N (NEUTRAL) position disengages both
the front and rear driveshafts from the
powertrain, and will allow the vehicle to
roll, even if the automatic transmission is
in PARK (or manual transmission is in gear).
The parking brake should always be applied
when the driver is not in the vehicle.
CAUTION! (Continued)CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to
prevent damage to internal parts.

21_DPF_OM_EN_USC_t.book Page 216

STARTING AND OPERATING217
NOTE:
With electronically shifted transfer case:
Steps 2 through 3 are requirements that
must be met before pushing the N (Neutral)
button, and must continue to be met until the
shift has been completed. If any of these
requirements are not met before pushing the
N (Neutral) button or are no longer met
during the shift, the N (Neutral) indicator light
will flash continuously until all requirements
are met or until the N (Neutral) button is
released.
The ignition must be in the ON/RUN mode for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is
not in the ON/RUN mode, the shift will not
take place and no position indicator lights will
be on or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not
been met.
Shifting Out Of N (Neutral)
Use the following procedure to prepare your
vehicle for normal usage:

1. Bring the vehicle to a complete stop,
leaving it connected to the tow vehicle.

2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into NEUTRAL.

With manual shift transfer case, shift the
transfer case lever to the desired position.

With electronically shifted transfer case
with rotary selector switch, push and hold
the transfer case N (Neutral) button until
the N (Neutral) indicator light turns off.
After the N (Neutral) indicator light turns
off, release the N (Neutral) button. After
the N (Neutral) button has been released,
the transfer case will shift to the position
indicated by the selector switch.
With electronically shifted transfer case
with push-button selector switch, push
and hold the switch for the desired
transfer case position, until the N (Neutral) indicator light turns off and the
desired position indicator light turns on.
NOTE:
When shifting the transfer case out of
N (Neutral), turning the engine off is not
required, but may be helpful to avoid gear clash.
With 8-speed automatic transmission, the
engine must remain running, since turning the
engine off will shift the transmission to PARK
(and the transmission must be in NEUTRAL for
the transfer case to shift out of NEUTRAL).
5. Turn the engine off. Shift automatic transmission into PARK. On 8-speed
transmissions the shifter will automatically
select PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal, and check that the vehicle
operates normally.

SAFETY289
Follow the on screen prompts to select the
number of axles (1 - 3), the number of trailer
tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. The range is selectable anywhere
between 25-125 psi (172-862 kPa).
Once psi (kPa) is programmed, the pairing
screen appears. Tire sensors must be paired in
order shown. Starting with Tire 1, deflate tire by
5 psi (34 kPa) and wait for a horn chirp. It may
take up to three minutes for the chirp to occur,
indicating that the sensor has paired. Repeat
process on each tire, in order, until complete.
Do not exit the pairing screen until process is
complete. If pairing was unsuccessful, a double
horn chirp will sound, and a prompt on the
touchscreen will allow you to retry the
procedure; “Retry” will only appear when setup
fails. Each tire must be successfully paired
during a single pairing process to receive the
success screen.
NOTE:
If the pairing process times out after three
minutes of no communication with a sensor, a
double horn chirp will occur indicating the
pairing has failed and a message will display on
the radio indicating the process was unsuc -
cessful. Under certain circumstances, the double horn chirp may continue to happen
every three minutes indicating the failed
pairing. If this happens, the horn chirping may
be canceled by cycling the ignition button OFF
and then back to ON/RUN position.
Tire Pressure Monitoring System Low Pressure
Warnings
When a low tire pressure in one or more of the
active road tires is detected, the instrument
cluster will display a message stating “Trailer
Tire Pressure Low”. The instrument cluster will
then display the TTPMS graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the
instrument cluster graphic) to the customer
programmed target tire pressure value as
shown at the top of the TTPMS instrument
cluster graphic. Once the tire(s) are inflated, the
system will automatically update the graphic
display in the instrument cluster, returning to its
original color. The vehicle may need to be driven
for up to 10 minutes above 15 mph (24 km/h)
in order for the TTPMS to receive the updated
information.Service TTPMS Warning
If a system fault is detected, the instrument
cluster will display a “Trailer Tire Pressure
System Service Required” message for a
minimum of five seconds.

Once the system fault is corrected the "Trailer
Tire Pressure System Service Required" message
will no longer be displayed. The vehicle may need
to be driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TTPMS to receive the
trailer tire pressure information.

Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
message will be displayed in the Instrument
Cluster on the TTPMS instrument cluster
graphic when a trailer number is selected that
has not had trailer tire pressure sensors paired
