Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum set speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the ready state, the
instrument cluster display will read “ACC Ready.”
When the system is off, the instrument cluster display will
read “Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following con-
ditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is applied.
• When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
• When the vehicle speed is outside of the speed range.
• When the brakes are overheated. •
When the driver door is open at low speed.
• When the driver seat belt is unbuckled at low speed.
• ESC Full-Off Mode is active.
To Activate/Deactivate

346 STARTING AND OPERATING

NOTE:
•If your vehicle stays at standstill for longer than two
seconds, then the driver will either have to push the RES
(resume) button, or apply the accelerator pedal to reen-
gage the ACC to the existing set speed.
• ACC cannot be resumed if there is a stationary vehicle
in-front of your vehicle in close proximity.
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.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by
pushing the SET (+)button. The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•
Pushing the SET (+)button once will result ina1mph
increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph.
• If the button is continually pushed, the set speed will
continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the instrument cluster display.
Metric Speed (km/h)
• Pushing the SET (+)button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the button
results in an increase of 1 km/h.
• If the button is continually pushed, the set speed will
continue to increase in 10 km/h increments until the
button is released. The increase in set speed is reflected
in the instrument cluster display.

STARTING AND OPERATING 349

ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
Set Speed.
NOTE:After the ACC system holds your vehicle at a
standstill for approximately 3 consecutive minutes, the
parking brake will be activated, and the ACC system will
be cancelled.
While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened,
the parking brake will be activated, and the ACC system
will be cancelled.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or objects
in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.
Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the current ACC
system settings. The instrument cluster display is located
in the center of the instrument cluster. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button
(located on the steering wheel) until one of the following
appears in the instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”
354 STARTING AND OPERATING

The “ACC/FCW Limited Functionality Clean Front Wind-
shield” 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 functionality.
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.
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 temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your 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.
NOTE:
•
Aftermarket add-ons such as snow plows, lift kits, and
brush/grille bars can hinder module performance. En-
sure the radar/camera has no obstructions in the field of
view.
• Height modifications can limit module performance and
functionality.
• Do not put stickers or easy passes over the camera/
radar field of view.
• Any modifications to the vehicle that may obstruct the
field of view of the radar/camera are not recommended.

STARTING AND OPERATING 357

Cleaning Instructions
Dust and dirt can accumulate on the cover and block the
camera lens. Clean the camera lens with a soft microfiber
cloth, being careful not to damage or scratch the module.
Towing A Trailer
ACC while towing a trailer is recommended only with an
Integrated Trailer Brake Controller. Aftermarket trailer
brake controllers will not activate the trailer brakes when
ACC is braking.
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.
Offset Driving Condition Example
358 STARTING AND OPERATING

•The braking temperature exceeds normal range (over-
heated).
• The gear selector is removed from the DRIVE position.
• The driver switches ESC to full-off mode.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Turn Off
The system will turn off and erase the set speed in memory
if:
•The Normal (Fixed Speed) Cruise Control on/off button
is pushed.
• The ignition is turned OFF.
• You engage Four-Wheel Drive Low.
• The Adaptive Cruise Control (ACC) on/off button is
pushed.
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia and a detected obstacle when backing up or
moving forward, e.g. during a parking maneuver. If your
vehicle is equipped with the automatic braking function,
the vehicle brakes may be automatically applied and
released when performing a reverse parking maneuver if
the system detects a possible collision with an obstacle.
NOTE:
• The driver can override the automatic braking function
by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic brakes are being applied.
• Automatic brakes will not be available if ESC is not
available.
• Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
• The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
364 STARTING AND OPERATING

•The automatic braking function will not be available if
vehicle is in 4LO transfer case mode.
• The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
• The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.
• The driver can override the automatic braking function
by pressing the gas pedal, turning the rear system
ParkSense off via the Rear ParkSense switch, or chang-
ing the gear while the automatic brakes are being
applied.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected ob-
stacles when backing up in REVERSE gear. NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided to assist the driver and not to
substitute the driver.
• The driver must stay in full control of the vehicle’s
acceleration and braking and is responsible for the
vehicle’s movements.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommenda-
tions.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the instru-
ment cluster display indicating the vehicle is above
ParkSense operating speed. The system will become active
again if the vehicle speed is decreased to speeds less than
approximately 6 mph (9 km/h).

STARTING AND OPERATING 365

ParkSense Sensors
The six ParkSense sensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 inches (30 cm) up to
47 inches (120 cm) from the front fascia/bumper in the
horizontal direction, depending on the location, type and
orientation of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indi-
cate the distance between the rear fascia/bumper and/or
front fascia/bumper and the detected obstacle. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
ParkSense Display
The warning display will turn on indicating the system
status when the vehicle is in REVERSE or when the vehicle
is in DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right regions based on the
obstacle’s distance and location relative to the vehicle.
If an obstacle is detected in the left and/or right regions,
the display will show a single arc in the left and/or right
regions and the system will produce a tone. As the vehicle
moves closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.
