USING HILL DESCENT
CONTROL
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 0 mph (0 km/h). When
stopped, the parking brake must be
applied or the vehicle must be placed in
park (P) 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 3 mph
(5 km/h) and 20 mph (32 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 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 chime sounds
when the system is about to disengage for
cooling. At this time, manually apply the
brakes to maintain descent speed.
Using Hill Descent Control
Press and release the hill
descent button in the center of
the terrain management control.
The button illuminates and a chime sounds
when you switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
