PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction or wheel and tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTrac® system. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac®
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 AdvanceTrac® sensors.
Reducing the effectiveness of the AdvanceTrac® 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 AdvanceTrac® 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 AdvanceTrac® system activates, SLOW DOWN.
The AdvanceTrac® with Roll Stability Control™ system helps you keep
control of your vehicle when on a slippery surface. The electronic
stability control portion of the system helps avoid skids and lateral slides
and roll stability control helps avoid a vehicle rollover. The traction
control system helps avoid drive wheel spin and loss of traction. See the
Traction Controlchapter for details on traction control system
operation.

Hill descent control (if equipped)
Hill descent control allows the driver to set and maintain vehicle speed
while descending steep grades in various surface conditions.
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.
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.
WARNING:Hill descent control does not provide hill hold at
zero mph (0 km/h). When stopped, the parking brake must be
applied and/or the vehicle must be placed in P (Park) or it may roll
away.
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.
Enabling hill descent control and setting the descent speed
1. Press and release the hill descent button located on
the instrument panel. A light in the cluster will
illuminate and chime will sound when this feature is
activated.
2. 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 HDC switch is pressed
and HDC is active, the HDC telltale will flash.
•At speeds below 20 mph (32 km/h): When the HDC switch is pressed
and conditions are not correct for hill descent activation, the HDC
system will be enabled, the light in the cluster will be on solid and
HILL DESCENT CONTROL READY will be displayed in the message
center.
•At speeds above 20 mph (32 km/h): When the HDC switch is pressed,
the HDC system will be enabled, the light in the cluster will not be
illuminated and FOR HILL CNTRL, 20 MPH OR LESS will be displayed
in the message center.
Refer toMessage centerin theInstrument Clusterchapter for hill
descent control messages.

SENSING SYSTEM (IF EQUIPPED)
WARNING: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 in reverse on a flat surface at parking speeds.
Traffic control systems, 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.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING: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 the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING: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/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/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note:If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to theMyKey®chapter.
Note:If your vehicle is equipped with a fully integrated electronic trailer
brake controller (TBC) and a trailer with electric trailer brakes is
connected to your vehicle, the RSS will be disabled. When the vehicle is
shifted into reverse, the message center display will remain in the Rear
Park Aid Off selection. For more information on the TBC, refer to the
Towingchapter.

The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.
When receiving a detection warning, the radio volume is reduced to a
predetermined level. After the warning goes away, the radio volume
returns to the previous level.
Using the Rear Sensing System
The rear sensors are only active when the transmission is inR.Asthe
vehicle moves closer to the obstacle, the rate of the audible warning
increases. When the obstacle is fewer than 12 inches (30 centimeters)
away, the warning sounds continuously. If a stationary or receding object
is detected farther than 12 inches (30 centimeters) from the side of the
vehicle, the tone sounds for only three seconds. Once the system detects
an object approaching, the warning sounds again.
A. Coverage area of up to 6 feet
(2 meters) from the rear bumper
(with a decreased coverage area at
the outer corners of the bumper).
The system detects certain objects while the transmission is inR:
•and moving toward a stationary object at a speed of 3 mph (5 km/h)
or less.
•but not moving, and a moving object is approaching the rear of the
vehicle at a speed of 3 mph (5 km/h) or less.
•and moving at a speed of less than 3 mph (5 km/h) and a moving
object is approaching the rear of the vehicle at a speed of less than
3 mph (5 km/h).

REAR VIEW CAMERA SYSTEM (IF EQUIPPED)
WARNING:The rear view camera system is a reverse aid
supplement device that still requires the driver to use it in
conjunction with 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:Back up as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING:Use caution when turning camera features on or off
while in R (Reverse). Make sure the vehicle is not moving.
The rear view camera system provides a video image of the area behind
the vehicle.
During operation, lines appear in the display which represent your
vehicle’s path and proximity to objects behind the vehicle.
The camera is located on the
tailgate.
Using the Rear View Camera System
The rear view camera system displays what is behind your vehicle when
you place the transmission in R (Reverse). The system uses two types of
guides to help you see what is behind your vehicle:
1. Fixed guidelines: Show the actual path the vehicle is moving in while
reversing in a straight line, which can be helpful when backing into a
parking space or aligning the vehicle with another object behind the
vehicle.
