not been selected, the display will read “Adaptive Cruise
Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button is pushed, the
display will read “ACC SET.”
When ACC is set, the set speed will show in the instrument
cluster display.
The ACC screen may display if any of the following ACC
activities occur:
System Cancel
 Driver Override
 System Off
 ACC Proximity Warning
 ACC Unavailable Warning
The instrument cluster display will return to the last
display selected after five seconds of no ACC display
activity.
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is 20 mph
(32 km/h).
The system will cancel when the vehicle speed drops
below 15 mph (24 km/h).
When the system is turned on and in the ready state, the
instrument cluster displays “ACC Ready.”
When the system is off, the instrument cluster displays
“Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following conditions:
 When the brakes are applied.
 When the parking brake is applied.
 When the automatic transmission is in PARK, REVERSE
or NEUTRAL.
 When the vehicle speed is below the minimum speed
range.
 When the brakes are overheated.
To Activate/Deactivate
Push and release the Adaptive Cruise Control (ACC) on/off
button. The ACC menu in the instrument cluster displays
“ACC Ready.”
To turn the system off, push and release the Adaptive
Cruise Control (ACC) on/off button again. At this time, the
system will turn off and the instrument cluster displays
“Adaptive Cruise Control (ACC) Off.”
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the
SET (+) button or the SET (-) button and release. The
instrument cluster display will show the set speed.
NOTE:Fixed Speed Cruise Control can be used without ACC
enabled. To change between the different modes, push
the ACC on/off button which turns the ACC and the Fixed
Speed Cruise Control off. Pushing the Fixed Speed Cruise
Control on/off button will result in turning on (changing to)
Fixed Speed Cruise Control mode.
WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always
ensure the system is off when you are not using it.
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.

88STARTING 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 condition 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:
The Adaptive Cruise Control (ACC) on/off button is
pushed.
 The Fixed Speed Cruise Control on/off button is
pushed.
 The ignition is placed in the OFF position.
To Resume
If there is a set speed in memory, push the RES (resume)
button and remove your foot from the accelerator pedal.
The instrument cluster display 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.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
While ACC is set, you can increase speed by pushing the
SET (+) button, or decrease speed by pushing the SET (-)
button.
U.S. Speed (mph)
 Pushing the SET (+), or SET (-) button once will result in
a 1 mph speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 mph.
 If the button is continually pushed, the set speed will
continue to adjust in 5 mph increments until the button
is released. The new set speed is reflected in the instru -
ment cluster display.
Metric Speed (km/h)
 Pushing the SET (+), or SET (-) button once will result in
a 1 km/h speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 km/h.
 If the button is continually pushed, the set speed will
continue to adjust in 10 km/h increments until the
button is released. The new set speed is reflected in
the instrument cluster display.
NOTE:When you override and push the SET (+) button or SET (-)
button, the new set speed will be the current speed of the
vehicle.
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.

23_LA_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if the
engine’s braking power does not slow the vehicle suffi -
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
 The ACC system applies the brake down to 15 mph
(24 km/h) when following a vehicle ahead.
 The ACC system maintains set speed when driving
uphill and downhill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set
speed. When driving uphill and downhill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting will show in the instrument cluster
display.

Distance Settings

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
Úpage 87.
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 neces -
sarily 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.

90STARTING AND OPERATING
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.
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 malfunction 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 aftermarket
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 after -
market grille or modifying the grille is not recom -
mended. 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 recommended when using ACC.

23_LA_OM_EN_USC_t.book Page 90

STARTING AND OPERATING91
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

TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may increase or decrease the vehicle speed for stability,
with no vehicle ahead detected. Once the vehicle is out of
the curve, the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on hills.
ACC may not detect a vehicle in your lane depending on
the speed, vehicle load, traffic conditions, and the
steepness of the hill.

ACC Hill Example

LANE CHANGING
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the following lane
changing example, ACC has not yet detected the vehicle
changing lanes and it may not detect the vehicle until it's
too late for the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane. There
may not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the brakes
if necessary.

Lane Changing Example

NARROW VEHICLES
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.

Narrow Vehicle Example

23_LA_OM_EN_USC_t.book Page 91

92STARTING AND OPERATING
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or vehicles. For
example, ACC will not react in situations where the vehicle
you are following exits your lane and the vehicle ahead is
stopped in your lane. It will consider this stopped vehicle a
stationary object as it did not previously detect movement
from it. Always be attentive and ready to apply the brakes
if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia/bumper and a detected obstacle when backing up
(e.g. during a parking maneuver).
For limitations of this system and recommendations,
see
Úpage 95.
ParkSense will retain the last system state (enabled or
disabled) from the previous ignition cycle when the
ignition is changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. 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 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.

The vehicle is close to the obstacle when the warning display shows one flashing arc and sounds a continuous tone. The following chart shows the warning alert operation when the
system is detecting an obstacle:
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from within the Uconnect
system
Úpage 107.
The ParkSense Warning screen is located within the
instrument cluster display. It provides visual warnings to
indicate the distance between the rear fascia/bumper
and the detected obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled with
the ParkSense switch, located on the switch
panel below the Uconnect display. When the ParkSense switch is pushed to disable the
system, the instrument cluster will display the “ParkSense
Off” message for approximately five seconds. When the
gear selector is moved to REVERSE and the system is
disabled, the instrument cluster display will display the
“ParkSense Off” message for as long as the vehicle 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
