FORD 2012 Explorer v.2 - Manual (Page 278)

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.
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. Refer to
Message center in the Instrument Cluster chapter for more information.
Note that even if it was disabled before turning off the vehicle, trailer
sway control will be re-enabled at each new key cycle.
WARNING: Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
