(Continued)
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 311.
Adaptive Cruise Control (ACC) Operation
The Cruise Control buttons (located on the right
side of the steering wheel) operate the Adaptive
Cruise Control (ACC) system.

Adaptive Cruise Control Buttons

WARNING!

Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver
involvement. It is always the driver’s responsi -
bility to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the
vehicle ahead; and, most importantly, brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete atten -
tion is always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision and
death or serious personal injury.

The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.

21_LA_OM_EN_USC_t.book Page 97

98STARTING AND OPERATING
If ACC is set when the vehicle speed is below
20 mph (32 km/h), the set speed will default to
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below
20 mph (32 km/h).
If either system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can
cause the vehicle to continue to accelerate
beyond the set speed. If this occurs, the
message “DRIVER OVERRIDE” will display in the
instrument cluster display.

If you continue to accelerate beyond the set
speed while ACC is enabled, the system will not
be controlling the distance between your
vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of
the accelerator pedal.

To Cancel
The following conditions cancel the ACC or Fixed
Speed Cruise Control systems:
The brake pedal is applied.
The parking brake is applied.
The CANC (cancel) button is pushed.
An Anti-Lock Brake System (ABS) event occurs.
The gear selector is removed from the DRIVE
position.
The Electronic Stability Control/Traction Control
System (ESC/TCS) activates.
The following conditions will only cancel the ACC
system:

The vehicle speed goes below 15 mph (24 km/h).

To Turn Off
The system will turn off and erase the set speed in
memory if:

will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
WARNING!
In Fixed Speed Cruise Control mode, the system
will not react to vehicles ahead. In addition, the
proximity warning does not activate and no
alarm will sound even if you are too close to the
vehicle ahead since neither the presence of the
vehicle ahead nor the vehicle-to-vehicle distance
is detected. Be sure to maintain a safe distance
between your vehicle and the vehicle ahead.
Always be aware which mode is selected.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.

21_LA_OM_EN_USC_t.book Page 98

100STARTING AND OPERATING
To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the Adaptive Cruise
Control (ACC) Set With Target Vehicle Light, and the
system adjusts vehicle speed automatically to
maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú page 97.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE!” will flash in the
instrument cluster display and a chime will sound
while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.
Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn
signal and will only be active when passing on the
left hand side.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and a chime will
sound when conditions temporarily limit system
performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system may
also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
“ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e. tunnels
with reflective tiles, or ice and snow). The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.

21_LA_OM_EN_USC_t.book Page 100

STARTING AND OPERATING101
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the center of the vehicle behind the lower grille.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an authorized
dealer for service.
Do not attach or install any accessories near the
sensor, including transparent material or after -
market grilles. Doing so could cause an ACC
system failure or malfunction.
When the condition that deactivated the system is
no longer present, the system will return to the
“Adaptive Cruise Control Off” state and will resume
function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster
displays “ACC/FCW Unavailable Service Required”
or “Cruise/FCW Unavailable Service Required”,
there may be an internal system fault or a
temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable
under normal conditions, ACC will be temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not advised when using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

104STARTING AND OPERATING
PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view. The
sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm) from
the rear fascia/bumper in the horizontal direction,
depending on the location, type and orientation of
the obstacle.
PARKSENSE DISPLAY
When the vehicle is in REVERSE, the warning
display will turn on indicating the system status.
The system will indicate a detected obstacle by
showing a single arc in one or more regions based
on the obstacle’s distance and location relative to
the vehicle.
If an obstacle is detected in the center rear region,
the display will show a single solid arc in the center
rear region and will produce a one-half second
tone. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to
the vehicle and the sound tone will change from
slow, to fast, to continuous. If an obstacle is detected in the left and/or right
rear region, the display will show a single flashing
arc in the left and/or right rear region and will
produce a fast sound tone. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the
sound tone will change from fast to continuous.

is in REVERSE.

The ParkSense switch LED will be on when
ParkSense is disabled or requires service. The
ParkSense switch LED will be off when the system is
enabled. If the ParkSense switch is pushed, and the
system requires service, the ParkSense switch LED
will blink momentarily, and then the LED will be on.

SERVICE THE PARKSENSE REAR PARK
A
SSIST SYSTEM
During vehicle start up, when the ParkSense Rear
Park Assist System has detected a faulted
condition, the instrument cluster will actuate a
single chime, once per ignition cycle and it will
display the “PARKSENSE UNAVAILABLE WIPE
REAR SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for five seconds.
When the gear selector is moved to REVERSE and
the system has detected a faulted condition, the
instrument cluster display will display the
“PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for as long as the
vehicle is in REVERSE. Under this condition,
ParkSense will not operate.
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” appears in the instrument cluster
display, make sure the outer surface and the
inside of the rear fascia/bumper is clean and clear
of snow, ice, mud, dirt or other obstruction, and
then cycle the ignition. If the message continues to
appear see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE
REQUIRED” appears in the instrument cluster
display, see an authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist sensors with water, car
wash soap and a soft cloth. Do not use rough or
hard cloths. In washing stations, clean sensors
quickly keeping the vapor jet/high pressure
washing nozzles at least 4 inches (10 cm) from the
sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the rear fascia/bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of
ParkSense or render the system temporarily
unavailable.
When you turn ParkSense off in DRIVE, the
instrument cluster will display "PARKSENSE
OFF" for five seconds. Furthermore, once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.

21_LA_OM_EN_USC_t.book Page 107

108STARTING AND OPERATING
ParkSense will reduce the volume of the radio
when it is sounding an audio tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind the fascia/bumper, or it could provide a
false indication that an obstacle is behind the
fascia/bumper.
Ensure the ParkSense system is off if objects
such as bicycle carriers, trailer hitches, etc., are
placed within 12 inches (30 cm) from the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be shown in the instrument cluster display.
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to
see an on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put into
REVERSE. The ParkView camera is located on the
rear of the vehicle above the rear license plate. The
image will be displayed in the touchscreen display
along with a caution note to “Check Entire
Surroundings” across the top of the screen. After
five seconds, this note will disappear.
NOTE:The ParkView Rear Back Up Camera has program -
mable modes of operation that may be selected
through the Uconnect system Ú page 120.If your vehicle is equipped with the Camera Delay
feature and it is turned on, the rear camera image
will be displayed for up to 10 seconds when the
vehicle is shifted out of REVERSE. However, this
feature is canceled if the forward vehicle speed
exceeds 8 mph (13 km/h), the transmission is
shifted into PARK, the vehicle's ignition is placed in
the OFF position, or by pressing the image defeat X
button.
When the vehicle is shifted out of REVERSE with
Camera Delay turned off, the rear camera mode is
exited and the last touchscreen appears again.
When enabled, active guidelines are overlaid on
the image to illustrate the width of the vehicle and
its projected backup path based on the steering
wheel position. The active guidelines will show
separate zones that will help indicate the distance
to the rear of the vehicle.
If the vehicle speed remains below 8 mph (13 km/
h), the rear view camera image will continue to be
displayed until the transmission is shifted into
PARK, the vehicle’s ignition is placed in the OFF
position, or the image defeat X button is pressed.
Different colored zones indicate the distance to
the rear of the vehicle.
WARNING!
Drivers must be careful when backing up even
when using the Rear Park Assist system. Always
check carefully behind your vehicle, and be sure
to check for pedestrians, animals, other
vehicles, obstructions, or blind spots before
backing up. You are responsible for the safety of
your surroundings and must continue to pay
attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom
-
mended that the driver looks over his/her
shoulder when using ParkSense.

camera is unable to view every obstacle or
object in your drive path.
To avoid vehicle damage, the vehicle must be
driven slowly when using ParkView to be able
to stop in time when an obstacle is seen. It is
recommended that the driver look frequently
over his/her shoulder when using ParkView.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
