GAIN Adjustment Buttons (+/-)
Pressing 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 condi-
tions 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 your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connec-
tions 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
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.356 STARTING AND OPERATING

6. Press the SELECT button and then press the UP or
DOWN buttons until the proper Trailer Brake Type
appears on the screen.
7. Use the GAIN adjustment (+/-) buttons to increase or
decrease the GAIN setting to the desired starting point. A
GAIN setting of 5 is a good starting point. 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.
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.358 STARTING AND OPERATING

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 air trailer brake systems and other systems not
compatible with ITBM. To determine the type of
brakes on your trailer and the availability of control-
lers, 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,
stop lights and turn signals on the trailer are required for
motoring safety.
NOTE: Do not cut or splice wiring into the vehicle’s
wiring harness.
5 STARTING AND OPERATING 359

WARNING!Any work done to the vehicle’s electrical system or
wiring should be performed by a qualified automo-
tive technician. If done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.
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. How-
ever, if frequent shifting occurs while in this range, select
“TOW/HAUL” mode or select a lower gear using the
Electronic Range Select (ERS) feature. NOTE: Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy operating
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.
The automatic transmission fluid and filter should be
changed if you regularly tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level
before towing.
Tow/Haul
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) feature) on more severe
grades.360 STARTING AND OPERATING

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 ONLY if the rear wheels are OFF the 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 set the parking brake. Place the transmission in
PARK.
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions. 5. Remove the key fob from the ignition switch.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position.
CAUTION!• Towing with the rear wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
• Do not disconnect the driveshaft because fluid
may leak from the transmission, causing damage
to internal parts.366 STARTING AND OPERATING
