WHAT IS 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.
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
Note:The system does not function below
3 mph (5 km/h).
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.The system can maintain vehicle speeds on
downhill slopes between 3–20 mph
(5–32 km/h). Above 20 mph (32 km/h), the
system remains on but the descent speed
cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The amount
of time that the system 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.
SWITCHING HILL DESCENT
CONTROL ON AND OFF
You can switch the hill descent control on
and off through the touchscreen.
SETTING THE HILL DESCENT
SPEED
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
WARNING: The system does not
control speed in low traction conditions or
extremely steep slopes. The system is
designed to be an aid and does not relieve
you of your responsibility to drive with due
care and attention. Failure to follow this
instruction could result in personal injury.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.

Hill Descent Control (If Equipped)

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system.
WARNING: The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash.
WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This may
cause reduced performance or false alerts.
WARNING: The system may not
detect small or moving objects, particularly
those close to the ground.
Note:If your vehicle has MyKey™, the sensing
system cannot be switched off when a
MyKey™ is present. See Principle of
Operation (page 78).Note:Keep the sensors on the bumper or
fascia free from snow, ice and large
accumulations of dirt. If the sensors are
covered, the system’s accuracy can be
affected. Do not clean the sensors with sharp
objects.
Note:If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
Note:Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device to
prevent false alerts.
Note:When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert.The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
touchscreen, information display or from the
pop-up message that appears once you shift
the transmission into reverse (R). If your
vehicle has a parking aid button, you can
switch the system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.
See Information Messages (page 142).

306
Adaptive Cruise Control (If Equipped)

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle’s regular brake system to prevent it
from overheating.
Note:An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
