Driving 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. 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. 299 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
