Hill Descent Control
|
|
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 allows you to set and maintain vehicle speed when descending steep grades in various surface conditions.
Hill descent control can maintain vehicle speeds on downhill grades between 0 mph (3 km/h) and 20 mph (32 km/h). Above 20 mph (32 km/h), the system remains armed, but you cannot use the system to set or maintain the descent speed.
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 provides a warning in the message center and a tone sounds when the system is about to disengage for cooling. At this time, manually apply the brakes as needed to maintain descent speed.
Press and release the hill descent button on the instrument panel. A light in the
cluster illuminates and a tone sounds when you switch this on.
To increase descent speed, press the accelerator pedal until you reach the speed you desire. To decrease descent speed, press the brake pedal until you reach the speed you desire.
When accelerating or decelerating, once you reach the descent speed you desire, remove your feet from the pedals and the hill descent control maintains the vehicle speed you chose.
Note: You may observe a noise from the ABS pump motor during hill descent control operation. This is a normal characteristic of the ABS and is no reason for concern.
Note: Refer to the Raptor Supplement for further information on Trail Control.
