FORD 2010 Expedition v.1 - Manual (Page 298)

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.
• Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
• Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
• Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
