During trailer sway control events, the stability control light in the

instrument cluster will flash momentarily. The 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

31 mph (50 km/h).

Disabling trailer sway control

Trailer sway control can be disabled during any key cycle. See trailer

sway control under the 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

3.7L, 5.0L and 3.5L EcoBoost™ engines:

Your vehicle is equipped with an electric power steering (EPS) system.

There is no fluid reservoir to check or fill.

If your vehicle loses electrical power while you are driving (or if the

ignition is turned off), you can steer the vehicle manually, but it takes

more effort. Under extreme usage conditions, the steering effort may

increase. This occurs to prevent overheating and permanent damage to

your steering system. If this should occur, you will neither lose the ability

to steer the vehicle manually nor will it cause permanent damage.

Typical steering and driving maneuvers will allow the system to cool and

steering assist will return to normal.

The EPS system has diagnostic checks that continuously monitor the

EPS system to ensure proper operation. When a system error is

detected, the following message SERVICE POWER STEERING, SERVICE

POWER STEERING NOW or POWER STEERING ASSIST FAULT may

display in the message center, refer to the Message center in the Driver

Controls chapter for more information.
