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 ad-
justed. See your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connec- tions according to the trailer manufacturer’s instruc-
tions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message should appear in the
EVIC (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 EVIC options. 4. Press the UP or DOWN button on the steering wheel
until “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 com-
pletely.

9. If the trailer wheels lockup (indicated by squealingtires), 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.

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 on
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 an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shiftingdoes occur while in DRIVE, select
“TOW/HAUL” mode or select a lower gear using the
Electronic Range Select (ERS) switches.
NOTE:Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy loading
conditions will improve performance and extend trans-
mission 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 forpolice, 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.
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.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.

Do not expect that the airbag will perform as de-
scribed earlier in this manual.
2500/3500 Models Only
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE:Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current Body
Builders Guide. See your authorized dealer, installer or
snowplow manufacturer for this information. There are
unique electrical systems that must be connected to
properly assure operator safety and prevent overloading
vehicle systems.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as de-
scribed earlier in this manual.
CAUTION!
The “Lamp Out” indicator could illuminate if exte-
rior lamps are not properly installed.
Before Plowing
• Check the hydraulic system for leaks and proper fluid
level.
• Check the mounting bolts and nuts for proper
tightness.
