Driving Enabling hill descent control and setting the descent speed 1. Press and release the hill descent button located on the instrument panel. A light in the cluster will illuminate and chime will sound when this feature is activated. 2. To increase descent speed, press the accelerator pedal until the desired speed is reached. To decrease descent speed, press the brake pedal until the desired speed is reached. Whether accelerating or decelerating, once the desired descent speed is reached, remove your feet from the pedals and the chosen vehicle speed will be maintained. Note: Noise from the ABS pump motor may be observed during hill descent control operation. This is a normal characteristic of the ABS and should be no reason for concern. Hill descent modes • At speeds below 20 mph (32 km/h): When the HDC switch is pressed and HDC is active, the HDC telltale will flash. • At speeds below 20 mph (32 km/h): When the HDC switch is pressed and conditions are not correct for hill descent activation, the HDC system will be enabled, the light in the cluster will be on solid and HILL DESCENT CONTROL READY will be displayed in the message center. • At speeds above 20 mph (32 km/h): When the HDC switch is pressed, the HDC system will be enabled, the light in the cluster will not be illuminated and FOR HILL CNTRL, 20 MPH OR LESS will be displayed in the message center. Refer to Message center in the Instrument Cluster chapter for hill descent control messages. STEERING To help prevent damage to the power steering system: • Never hold the steering wheel at its furthest turning points (until it stops) for more than three to five seconds when the engine is running. • Do not operate the vehicle with a low power steering pump fluid level (below the MIN mark on the reservoir). 282 2012 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
