Driving 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. HILL DESCENT CONTROL (IF EQUIPPED) Hill descent control allows the driver to set and maintain vehicle speed while descending steep grades in various surface conditions. WARNING: Hill descent control cannot control descent in all surface conditions and circumstances, such as ice or extremely steep grades. Hill descent control is a driver assist system and cannot substitute for good judgment by the driver. Failure to do so may result in loss of vehicle control, crash or serious injury. Hill descent control can maintain vehicle speeds on downhill grades between 2 mph (3 km/h) and 12 mph (20 km/h). Above 20 mph (32 km/h), the system remains armed, but descent speed cannot be set or maintained. WARNING: Hill descent control does not provide hill hold at zero mph (0 km/h). When stopped, the parking brake must be applied and/or the vehicle must be placed in P (Park) or it may roll away. Hill descent control requires a cooling down interval after a period of sustained use. The amount of time that the feature can remain active before cooling varies with conditions. The system will provide a warning in the message center and a chime will sound when the system is about to disengage for cooling. At this time, manually apply the brakes as needed to maintain descent speed. 281 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
