PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
Note:If your vehicle is equipped with MyKey, it is possible to prevent
turning the TCS off. Refer to theMyKeychapter.
In certain situations (e.g. stuck in snow or mud), turning the traction
control off may be beneficial as this allows the wheels to spin with full
engine power. Turn off the traction control system through the
information display.
System indicator lights and messages
WARNING:If a failure has been detected within the Traction
Control System, the stability control light will illuminate steadily.
Verify that the Traction Control System was not manually disabled using
the information display control. If the stability control light still
illuminates steadily, have the system serviced by an authorized dealer
immediately. Operating your vehicle with Traction Control disabled
could lead to an increased risk of loss of vehicle control, vehicle
rollover, personal injury and death.
The stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.
When the traction control system is turned off or on, a message appears
in the information display showing system status.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling characteristics
of the vehicle and may adversely affect the performance of the
AdvanceTracsystem. In addition, installing any stereo loudspeakers may
interfere with and adversely affect the AdvanceTracsystem. 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 AdvanceTracsensors. Reducing the effectiveness of
the AdvanceTracsystem 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
AdvanceTracsystem 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 AdvanceTracsystem helps you keep control of your vehicle when
on a slippery surface. The electronic stability control (ESC) portion of
the system helps avoid skids and lateral slides and the traction control
system (TCS) helps avoid drive wheel spin and loss of traction. (For
details on TCS operation, see theTraction Controlchapter.)

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.
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.

The system can be turned off using the information display control. Refer
to theInformation Displaychapter. If a fault is present in the system, a
warning message appears in the information display and does not allow
the driver to switch the faulted system on.
Note:If your vehicle is equipped with MyKey, it is possible to prevent
turning the sensing system off. Refer to theMyKeychapter.
Using the Rear Sensing System
The rear sensors are only active when the transmission is in R (Reverse).
As the vehicle moves closer to the obstacle, the rate of the audible
warning increases. When the obstacle is fewer than 10 inches (25
centimeters) away, the warning sounds continuously. If a stationary or
receding object is detected farther than 10 inches (25 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 in R
(Reverse):
•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).

ACTIVE PARK ASSIST (IF EQUIPPED)
WARNING:This system is designed to be a supplementary park
aid. It may not work in all conditions and is not intended to
replace the driver’s attention and judgment. The driver is responsible
for avoiding hazards and maintaining a safe distance and speed, even
when the system is in use.
Note:The driver is always responsible for controlling the vehicle,
supervising the system and intervening if required.
The system detects an available parallel parking space and automatically
steers the vehicle into the space (hands-free) while you control the
accelerator, gearshift and brakes. The system visually and/or audibly
instructs the driver to park the vehicle.
The system may not function correctly if something passes between the
front bumper and the parking space (i.e. a pedestrian or cyclist) or if the
edge of the neighboring parked vehicle is high from the ground (i.e. a
bus, tow truck or flatbed truck).
Note:The sensors may not detect objects in heavy rain or other
conditions that cause disruptive reflections.
Note:The sensors may not detect objects with surfaces that absorb
ultrasonic waves.
The system should not be used if:
•a foreign object (i.e. bike rack or trailer) is attached to the front or
rear of the vehicle or at another location close to the sensors.
•an overhanging object (i.e. surfboard) is attached to the roof.
•the front bumper or side sensors are damaged (i.e. in a collision) or
obstructed by a foreign object (i.e. front bumper cover).
•a mini-spare tire is in use.
