FORD 2010 Expedition v.2 - Manual (Page 300)

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 “sliding car” icon 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.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
• Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
• Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
