to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer
brake control for the specific towing condi
-
tion and should be changed as towing condi
-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi
-
tions 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 elec
-
trical connections 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 instrument
cluster display (if the connection is not
recognized by the ITBM, braking func
-
tions 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 suggested selection depends and may change depending on the customer preferences for braking performance. Condition of the trailer brakes, driving and
road state may also affect the selection.
