Trailer Brakes
WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 pounds (680 kilograms)
when loaded.
Integrated Trailer Brake Controller (If
Equipped)
WARNING
Use the integrated trailer brake
controller to properly adjust the
trailer brakes and check all
connections before towing a trailer. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.

When used properly, the trailer brake
controller assists in smooth and effective
trailer braking by powering the trailer's
electric or electric-over-hydraulic brakes
with a proportional output based on the
towing vehicle's brake pressure.
You can adjust the level of initial trailer
brake output by selecting one of three
settings using the information display.
Choose Low, Medium or High for the initial
trailer brake output you require. See
Information Displays (page 109).
The controller user interface consists of
the following:
A: + and - (Gain adjustment buttons):
Pressing these buttons adjusts the
controller's power output to the trailer
brakes in 0.5 increments. You can increase
the gain setting to 10.0 (maximum trailer
braking) or decrease it to 0 (no trailer
braking). The gain setting displays in the
message center.
