Aftermarket Electronic Trailer
Sway Control Devices
Some trailers may come equipped
with an electronic device designed to
reduce or control trailer sway.
Aftermarket equipment manufacturers
also offer similar devices that connect
to the wiring between the trailer and
the vehicle. These devices may
interfere with the vehicle s trailer
brake systems or other systems,
including integrated anti-sway
systems, if equipped. Messages related
to trailer connections or trailer brakes
could appear on the DIC. The effects
of these aftermarket devices on
vehicle handling or trailer brake
performance is not known.

Use of aftermarket electronic trailer
sway control devices could result in
reduced trailer brake performance,
loss of trailer brakes, or other
malfunctions, and result in a crash.
You or others could be seriously
injured or killed. Before using one
of these devices:
