PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
•
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the systems
applies higher brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one
or more of the wheels individually.

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,
remove your feet from the pedals. The
system maintains the chosen vehicle
speed.

The system will provide an image of your
vehicle and the sensor zones. The zones
will highlight green, yellow and red when
the parking aid sensors detect an object in
the coverage area.
Manual Zoom
WARNING: When manual zoom is
on, the full area behind your vehicle may
not show. Be aware of your surroundings
when using the manual zoom feature.
Note: Manual zoom is only available when
the transmission is in reverse (R).
Note: When you enable manual zoom, only
the centerline is shown.
Selectable settings for this feature are
Zoom in (+) and Zoom out (-). Press the
symbol in the camera screen to change the
view. The default setting is Zoom OFF.
This allows you to get a closer view of an
object behind your vehicle. The zoomed

active while the transmission is in reverse
(R).
Rear Camera Delay
Selectable settings for this feature are ON
and OFF.
The default setting for the rear camera
delay is OFF.
When shifting the transmission out of
reverse (R) and into any gear other than
park (P), the camera image remains in the
display until:
• Your vehicle speed reaches
approximately
5 mph (8 km/h).
• You shift your vehicle into park (P). 360 DEGREE CAMERA
(IF
EQUIPPED) WARNING:
The 360 degree
camera system still requires the driver
to use it in conjunction with looking out
of the windows, and checking the interior
and exterior mirrors for maximum
coverage. WARNING:
Objects that are close
to either corner of the bumper or under
the bumper, might not be seen on the
screen due to the limited coverage of the
camera system. 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. WARNING: You are responsible for
controlling your vehicle at all times. 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
the loss of control of your vehicle,
personal injury or death.
Note: Use caution using the 360 view when
any of the doors are ajar. If a door is ajar, the
camera becomes out of position and the
video image could be incorrect.
The 360 degree camera system consists
of front, side and rear cameras. The
system:
• Allows you to see what is directly in
front or behind your vehicle.
• Provides cross traffic view in front and
behind your vehicle.

The radar sensor is in the lower grille.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Note: Keep the front of your vehicle free of
dirt, metal badges or objects. Vehicle front
protectors, aftermarket lights, additional
paint or plastic coatings could also degrade
sensor performance.
A message displays if something obstructs
the camera or the sensor. When something
blocks the sensor, the system cannot
detect a vehicle ahead and does not
function. See Adaptive Cruise Control
– Information Messages (page 256).
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle image does
not illuminate if the system does not
detect a vehicle in front of you. Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly.
If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.
