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.
If a fault is detected in the trailer wiring or the
Integrated Trailer Brake Module (ITBM), the Trailer
Brake Status Indicator Light will flash.
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
connections according to the trailer manufacturer's
instructions.
3. When a trailer is plugged in with electric or EOH
brakes, the trailer connected message should
appear in the instrument cluster display (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 instrument cluster display
options.
4. Push the UP or DOWN button on the steering wheel
until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to
enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer
Brake Type appears on the screen.
7.
Push the RIGHT arrow and then push 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.

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
conditions include trailer load, vehicle load, road
conditions and weather.
