Terrain Response (If Equipped) PRINCIPLE OF OPERATION WARNINGS 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 does not provide hill hold at zero miles per hour (0 kilometers per hour). When stopped, the parking brake must be applied or the vehicle must be placed in P (Park) or it may roll away. Hill descent control allows the driver to set and maintain vehicle speed while descending steep grades in various surface conditions. 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. 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. USING HILL DESCENT CONTROL Press and release the hill descent button located on the E163957 instrument panel. A light in the cluster will illuminate and a chime will sound when this feature is activated. 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 between 2 mph (3.2 km/h) and 20 mph (32 km/h): When the Hill Descent Control switch is pressed and Hill Descent Control is active, the Hill Descent Control telltale flashes. Your vehicle maintains your desired speed. At speeds between 20 mph (32 km/h) and 40 mph (64 km/h): When the Hill Descent Control switch is pressed, the Hill Descent Control system is enabled, the Hill Descent Control telltale is solid and a message displays in the information display. Your vehicle does not maintain your desired speed and you cannot set your descent speed. • 200 F-150 (), enUSA, First Printing
