TRAILER SWAY CONTROL
When properly equipped, trailer sway control will use the vehicle's
AdvanceTrac with RSC system to detect and help reduce trailer sway
by applying brake force at individual wheels and, if necessary, by
reducing engine power. Trailer sway control is only enabled above
40 mph (64 km/h).
WARNING: Trailer sway control does not prevent a trailer from
swaying. It mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway, it is likely that the
trailer is improperly loaded for the correct tongue weight or the speed
of the vehicle and trailer is too high. Pull the vehicle-trailer over to a
safe location to check the trailer weight distribution and tongue load,
and reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The message center will also
display TRAILER SWAY REDUCE SPEED. In some cases when trailer
sway is detected, the vehicle speed is too high and may be at or above a
speed at which trailer sway will grow continuously. This may cause the
system to activate multiple times, and you may experience a slight
deceleration of the vehicle.
