Trailer sway control
Your vehicle may be equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTrac
威
with
RSC
威
system to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
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 cluster 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
above a speed at which trailer sway will not grow continuously. This may
cause the system to activate multiple times, causing a gradual reduction
in speed.
Note:
The trailer sway control will only activate at speeds greater than
40 mph (64 km/h).
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. See
Message
center
in the
Instrument Cluster
chapter. Note that regardless of chosen
enable state, 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.
