sliding the manual brake control lever will display the

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 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.
