ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
Electronic Speed Control function performs differently.
Please refer to the proper section within this chapter.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor and a forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed. •
If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
• Normal (fixed speed) electronic speed control mode
for cruising at a constant preset speed. For additional
information, refer to “Normal (Fixed Speed) Cruise
Control Mode” in this section.
NOTE: Normal (fixed speed) electronic speed control
will not react to preceding vehicles. Always be aware of
the mode selected.
182 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
To decrease the distance setting, push the Distance Set-
ting — 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 EVIC/DID displays the “Sensed Vehicle
Indicator” icon, 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. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, 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 EVIC/DID and a chime will
sound while ACC continues to apply its maximum
braking capacity.

Push the SET + or the SET- button (located on the steering
wheel) and the following will display in the EVIC/DID:
ACC SET
When ACC is set, the set speed will display in the
instrument cluster.
The ACC screen may display once again if any ACC
activity occurs, which may include any of the following:
•System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable Warning
• The EVIC/DID will return to the last display selected
after five seconds of no ACC display activityDisplay Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate 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 EVIC/DID 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 the3

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 Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
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 impor-
tant 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 malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
•
Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles. Do-
ing 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 your authorized dealer.
198 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
•Installing a snow plow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and also a chime will indicate
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions, such as
mud, dirt, or ice on windshield and fog on the inside of
glass. In these cases, the EVIC/DID will display “ACC/
FCW Limited Functionality Clean Front Windshield” and
the system will have degraded performance.
The “ACC/FCW Limited Functionality Clean Front
Windshield” message can sometimes be displayed while
driving in adverse weather conditions. The ACC/FCW system will recover after the vehicle has left these areas.
Under rare conditions, when the camera is not tracking
any vehicles or objects in its path this warning may
temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may
require cleaning or removal of an obstruction.
When the condition that created limited functionality is
no longer present, the system will return to full function-
ality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at your authorized dealer.

FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC/DID), and may apply
a brake jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning. If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle
and mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system deter-
mines that the driver intends to avoid the collision by
braking but has not applied sufficient brake force, the
system will compensate and provide additional brake
force as required.
If a Forward Collision Warning with Mitigation event
begins at a speed below 20 mph (32 km/h), the system
may provide the maximum braking possible to mitigate
the potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle com-
pletely, the system will hold the vehicle at standstill for
two seconds and then release the brakes.3

ParkSense can be active only when the shift lever/gear
selector is in REVERSE. If ParkSense is enabled at this
shift lever/gear selector position, the system will remain
active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. When in REVERSE
and above the system’s operating speed, a warning will
appear within the Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID) indicating
the vehicle speed is too fast. The system will become
active again if the vehicle speed is decreased to speeds
less than approximately 6 mph (9 km/h).
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 in (30 cm) up to 79 in(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from the Customer -
Programmable Features section of the Uconnect System.
Refer to
Uconnect Settings” in “Understanding Your
Instrument Panel” for further information.
The ParkSense Warning screen is located within the
EVIC/DID. It provides visual warnings to indicate the
distance between the rear fascia/bumper and the de-
tected obstacle. Refer to “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)” for
further information.3

Service The ParkSense Rear Park Assist 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 the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message. Refer to “Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID)” for further
information. When the shift lever/gear selector is moved
to REVERSE and the system has detected a faulted
condition, the EVIC/DID will display thePARKSENSE
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 SEN-
SORS” appears in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) make sure the outer surface and the underside 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 EVIC/DID, see an authorized dealer.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors. Otherwise, you could dam-
age the sensors.
ParkSense System Usage Precautions
NOTE:
•
Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense system operating
properly.
