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

E163957

Press and release the hill
descent button located on the
instrument panel. A light in the

cluster will illuminate and a chime will
sound when this feature is activated.

To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.

Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed will be maintained.

Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.

Hill descent modes

•

At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.

•

At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.

•

At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

(If Equipped)

Refer to the Information Displays for
additional Hill Descent Control messages.

PRINCIPLE OF OPERATION

WARNINGS

To help avoid personal injury, please
read and understand the limitations
of the system as contained in this

section. Sensing is only an aid for some
(generally large and fixed) objects when
moving on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, inclement
weather, air brakes, and external motors
and fans may also affect the function of
the sensing system. This may include
reduced performance or a false activation.

To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.

This system is not designed to
prevent contact with small or moving
objects. The system is designed to

provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground.

Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the

normal detection zone of the system, may
create false beeps.

Note: Keep the sensors, located 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 alarms.

Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 61).

Note: If your vehicle is equipped with a
trailer tow package and a trailer is
connected to your vehicle, the rear sensing
system disables and you cannot switch the
system on through the information display.

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.

When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level.

E139213

You can turn the system on or
off by pressing the parking aid
button. If your vehicle does not

have a parking aid button, the system can
be switched off through the information
display menu or from the pop-up message
that appears once you shift the
transmission into reverse (R). See General
Information (page 111).

If a fault is present in the system, a warning
message appears in the information
display and you cannot switch the system
on through the pop-up message. See
Information Messages (page 128).

REAR PARKING AID

The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than 12 in
(30 cm) away, the warning sounds
continuously. If the system detects a
