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 and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
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 Press the button on the center
console. A light illuminates in the
control and a tone sounds when
the system is active.
SETTING THE HILL DESCENT
SPEED WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. 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.
When you reach the speed you prefer,
either by accelerating or decelerating,

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 64).
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.

of sensors not operating correctly, not enough room
for your vehicle, or the traction control is off.
The system does not correctly
operate.
You may have switched traction control off.
The system does not search for
a parking space.
The transmission is in reverse (R). Your vehicle must
be moving forward to be able to detect a parking space.
There could be blockage on the sensors. For example,
snow, ice or large accumulations of dirt. Blocked
sensors can affect how the system functions.
The system does not offer a
parking space.
The sensors in the front or rear bumper could be
damaged.
There is not enough room in the parking space for your

WARNING: Use caution when the
rear cargo door is ajar. If the rear cargo
door is ajar, the camera will be out of
position and the video image may be
incorrect. All guidelines disappear when
the rear cargo door is ajar. Failure to
follow this instruction could result in
personal injury. WARNING:
Use caution when
turning camera features on or off when
the transmission is not in park (P). Make
sure your vehicle is not moving.
Note: Some vehicles may not come
equipped with guidelines.
The rear view camera system provides a
video image of the area behind your
vehicle.
During operation, lines appear in the
display which represent your vehicle ’s path
and proximity to objects behind your
vehicle. The camera is located on the luggage
compartment door.
Using the Rear View Camera
System
The rear view camera system displays
what is behind your vehicle when you place
the transmission in reverse (R). Note:
The reverse sensing system is not
effective at speeds above
3 mph (5 km/h)
and may not detect certain angular or
moving objects.
The system uses three types of guides to
help you see what is behind your vehicle:
• Active guidelines (if equipped): Show
the intended path of your vehicle when
reversing.
• Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object (for
example, a trailer).
Note: If the transmission is in reverse (R)
and the luggage compartment door or
liftgate is open, no rear view camera
features will display.
Note: When towing, the camera only sees
what you are towing. This might not provide
adequate coverage as it usually provides in
normal operation and some objects might
not be seen. In some vehicles, the guidelines
may disappear when you connect the trailer
tow connector.
The camera may not operate correctly
under the following conditions:
• Nighttime or dark areas if one or both
reverse lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner. You can also use the rear
washer to clean the camera. See Rear
Window Wiper and Washers
(page
86).
• The rear of your vehicle is hit or
damaged, causing the camera to
become misaligned.
