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.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 245). Vehicle without stability control

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
You can switch the hill descent control on
and off through the touchscreen. 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.

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 73). 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.
You can switch the system off through the
touchscreen, information display or from the
pop-up message that appears once you shift
the transmission into reverse (R). If your
vehicle has a parking aid button, you can
switch the system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 134).
REAR PARKING AID 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:
The system may not
detect small or moving objects, particularly
those close to the ground.

•
As the distance to the object decreases,
the indicator blocks illuminate and move
toward the vehicle icon.
• If there is no object detected, the
distance indicator blocks are gray.
When you shift into reverse (R), the system
provides audible warnings and visual
indication when detected objects are within
24 in (60 cm) and are inside the driving path
of your vehicle. When you stop your vehicle,
the audible warnings turn off after two
seconds.
When you shift into any forward gear, the
system provides audible warnings and visual
indication when your vehicle is moving at a
speed of approximately
5 mph (8 km/h) or
below and the system detects an object
within the detection zone. When you stop
your vehicle, the audible warnings turn off
after two seconds and visual indication turns
off after four seconds. When you shift into neutral (N), the system
only provides visual indication if your vehicle
is moving at a speed of approximately 5 mph
(8 km/h)
or below. For example, your vehicle
is moving on a slope, and the system detects
an object moving toward your vehicle. When
you stop your vehicle, visual indication turns
off after four seconds.
If the system is not available, the side
distance indicator blocks do not display.
ACTIVE PARK ASSIST
(IF EQUIPPED) WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The sensors may not
detect objects in heavy rain or other
conditions that cause interference. 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.
The system assists parking into and out of
parking spaces. Sensors are used to detect

WARNING: Pay close attention to
changing road conditions such as entering
or leaving a highway, on roads with
intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. 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. WARNING:
The system is not a crash
warning or avoidance system. WARNING:
Do not use the system
when towing a trailer that has aftermarket
electronic trailer brake controls. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Do not use tire sizes
other than those recommended because
this can affect the normal operation of the
system. Failure to do so may result in a loss
of vehicle control, which could result in
serious injury. WARNING:
Do not use the system
with a snow plow blade installed. WARNING:
Do not use the system in
poor visibility, for example fog, heavy rain,
spray or snow.
When Following a Vehicle WARNING: When following a vehicle
that is braking, your vehicle does not
always decelerate quickly enough to avoid
a crash without driver intervention. Apply
the brakes when necessary. Failure to
follow this instruction could result in
personal injury or death. Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle
’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.

Following a Vehicle
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in the
same lane, the vehicle speed adjusts to
maintain the gap setting. Note:
When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small temporary
acceleration to help you pass.
Your vehicle maintains a consistent gap from
the vehicle ahead until:
• The vehicle in front of you accelerates to
a speed above the set speed.
• The vehicle in front of you moves out of
the lane you are in.
• You set a new gap distance.
The system applies the brakes to slow your
vehicle to maintain a safe gap distance from
the vehicle in front. The system only applies
limited braking. You can override the system
by applying the brakes.
Note: The brakes may emit noise when
applied by the system.
