Hill Descent Control (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 systemand cannot substitute for good judgment by the driver. Failure to do somay 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, you must apply the parking brake or place the vehicle in P (Park), or it may roll away. Hill descent control allows you to set and maintain vehicle speed while descending steep grades in various surface conditions. Hill descent control can maintain vehicle speeds ondownhill grades between 2mph (3 km/h) and 12mph (20 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. USINGHILL DESCENT CONTROL 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. E163957

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 pumpmotor during hill descent control operation. This is a normal characteristic of the ABS and is no reason for concern.
