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
1. Press and release the hill descent
button located on the center console.
Switching on this feature will light the
button and sound a tone.
2. Press the accelerator pedal to increase
descent speed until you have reached
the desired speed.
3. Press the brake pedal to decrease
descent speed until you have reached
the desired speed.
Note: Once you have reached the desired
descent speed, remove your feet from the
pedals to maintain the chosen vehicle
speed.
See the Information Displays chapter of
your Owner’s Manual for hill descent
mode messages.
Disabling Hill Descent Control
To switch off the hill descent control, press
the button located on the center console
a second time. The light will turn off and
the information display will indicate that
you have switched this off.
