The trailer brake type can be changed
on the multimedia display.
1 Select the multimedia display.
2 Select “Vehicle customize”.
3 Select “Utility”.
4 Select “Brake type”.
Changing trailer brake type will cause the
current “Gain” setting to reset to zero.
Make sure to set the “Gain” as described
in the following section.
“Gain” setting on trailer brake control-
ler should be set for a specific towing
condition. “Gain” setting should be
adjusted each time the vehicle load,
trailer load, road conditions, or
weather changes. Setting the “Gain”
value to 0 will disable the trailer brake
controller output.
1 Make sure the trailer brakes are in
good working condition and func-
tioning normally. See trailer dealer
if necessary.
2 Hook up the trailer and make
proper electrical connections.
3 Select the correct type of trailer
brakes that are equipped on the
trailer by using the multimedia dis-
play.
4 Drive vehicle with trailer attached
on a level road surface similar to
towing condition and in traffic-free
environment. Driving speed should
be approximately 20 - 25 mph (35
- 40 km/h).
5 Using the “GAIN” (+/-) selection
buttons, set a starting “Gain” of 5.0.
6 While driving 20 - 25 mph (35 -
40 km/h), fully apply the manual
brake slider.
7 Adjust the “Gain” setting, using the
“GAIN” (+/-) selection buttons, to
either increase or decrease to just
below the point of trailer wheel
lock-up.
8 For confirmation, repeat steps 6
and 7 until desired “Gain” setting is
reached (just below point of trailer
wheel lock-up).
■ When setting the “Gain”
Wheel lock-up occurs when the trailer
wheel squeals or tire smoke occurs. Trailer
wheels may not lockup while driving heavily
loaded trailer. During this case, adjust the
Trailer “Gain” to the highest allowable set-
ting for the towing condition.
■ Trailer Sway Control Function
Helps suppress trailer sway at an early
stage by using the trailer brake control sys-
tem to operate the trailer brakes.
