WARNING:
Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. TSC cannot stop all trailers from swaying. 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. Always use caution when towing a trailer and follow the
tongue weight recommendations. Refer to the
Trailer towing
section
in the
Tires Wheels and Loading
chapter of this owner’s guide for
more information on towing a trailer with your vehicle.
During Trailer Sway Control events the
icon in the instrument cluster
will flash momentarily. 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. Pressing and
holding the AdvanceTrac
威
with RSC
威
button for more than five seconds
will disable the Trailer Sway Control feature and the
icon will flash
momentarily and then illuminate solid for that ignition cycle. Trailer
Sway Control can be re-enabled by momentarily pressing the
AdvanceTrac
威
with RSC
威
button. Trailer Sway Control will also 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.
