4. Press the UP or DOWN button on the steering wheeluntil “VEHICLE SETTINGS” appears on the screen.
5. Press the RIGHT arrow on the steering wheel to enter “VEHICLE SETTINGS”.
6. Press the UP or DOWN buttons until Trailer Brake Type appears on the screen.
NOTE: 1500 Models Only – Light Electric and Heavy
Electric will only be available due to the tow capacities of
the vehicle.
7. Press the RIGHT arrow and then press 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.

depending on the customer preferences for braking per-
formance. Condition of the trailer brakes, driving and

EVIC Display Messages
The trailer brake control interacts with the Electronic
Vehicle Information Center (EVIC). 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. Refer to “Electronic
Vehicle Information Center” in “Understanding Your
Instrument Panel” for further information.
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 a increase in stop-
ping distance or trailer instability which could result
in damage to your vehicle, trailer, or other property.
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 a increase in stop-
ping distance or trailer instability which could result
in personal injury.
NOTE:
• An aftermarket controller may be available for use
with trailers with air or electric-over-hydraulic trailer
brake systems. To determine the type of brakes on5

your trailer and the availability 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 your authorized dealer if
an aftermarket module is to be installed.
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 har-
ness and connector. NOTE:
Do not cut or splice wiring into the vehicles
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.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area 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) switches).
NOTE:Using “TOW/HAUL” mode or selecting a lower
gear range (using the ERS switches) 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. 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 switches) can help to
avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified for
police, taxi,
fleet, or frequent trailer towing.. Refer to “Maintenance
Schedule” for the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) switches) on more severe
grades.
560 STARTING AND OPERATING

Electronic Speed Control – If Equipped
•Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting and Operating” for
further information.
NOTE:
The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE: Do not use this model vehicle for snowplow
applications.

NOTE:Vehicles equipped with air suspension must be
lowered to the “Entry/Exit” (lowest) level, and have
automatic leveling disabled, before tying them down
(from the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be lowered to the “Entry/Exit” level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition switch to the OFF position and remove the key fob.
6. Install a suitable clamping device, designed for tow- ing, to secure the front wheels in the straight position.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting and Operating” section.NOTE:
Vehicles equipped with air suspension must be
lowered to the Park (lowest) level, and have automatic
leveling disabled, before tying them down (from the
body) on a trailer or flatbed truck. Refer to Air Suspen-
sion inStarting and Operating for more information. If
the vehicle cannot be lowered to the Park level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
