level ground before pushing the SET (+) or SET (-) button.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set 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 (+) or SET (-) button,
the new set speed will be the current speed of the vehicle.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is released,
the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
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).
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
WARNING!
Leaving the Cruise Control 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 an accident. Always ensure the system
is off when you are not using it.

(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 “ACC 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 control the
distance between your vehicle and the vehicle ahead.
The vehicle speed will only be determined by the posi -
tion of the accelerator pedal.
To Cancel
The following conditions cancel the ACC or Fixed Speed
Cruise Control systems:
 The brake pedal is applied
 The CANC (cancel) button is pushed
 The Anti-Lock Brake System (ABS) activates
 The trailer brake is applied manually (if equipped)
 The gear selector is removed from the DRIVE position
 The Electronic Stability Control/Traction Control
System (ESC/TCS) activates 
The vehicle parking brake is applied
 The Trailer Sway Control (TSC) activates
 The driver switches ESC to Full Off mode
 The braking temperature exceeds normal range
(overheated)
The following conditions will only cancel the ACC system:
 Driver seat belt is unbuckled at low speeds
 Driver door is opened at low speeds
To Turn Off
The system will turn off and clear 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
 4WD Low is engaged
To Resume
If there is a set speed in memory, push the RES (resume)
button and then 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.
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 leave
the system 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.

23_DT_OM_EN_USC_t.book Page 147

148STARTING AND OPERATING
Resume can be used at any speed above 0 mph (0 km/h)
when ACC is active.
NOTE:
If your vehicle is at a standstill for longer than two
seconds, then the driver will either have to push the
RES (resume) button, or apply the accelerator pedal to
reengage the Adaptive Cruise Control (ACC) to the
existing set speed.
 ACC cannot be resumed if there is a stationary vehicle
in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set 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 (-)
buttons, the new set speed will be the current speed of the
vehicle.
When ACC Is Active
 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 decelerates the vehicle to a full stop
when following the vehicle in front. If your vehicle
follows the vehicle in front to a standstill, after two
seconds 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.
 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 Adaptive Cruise
Control (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
displays in the instrument cluster display.
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_DT_OM_EN_USC_t.book Page 148

STARTING AND OPERATING149

Distance Settings

To increase the distance setting, push the Distance
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
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 displays the ACC Set
With Target Detected Indicator 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.
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 mean
that the Forward Collision Warning system is applying the
brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (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.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following the vehicle in front, if the vehicle
in front 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 vehicle in front 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 three consecutive minutes, the parking
brake will be activated, and the ACC system will be
canceled.
While ACC is holding your vehicle at a standstill, if the
driver seat belt is unbuckled or the driver door is opened,
the parking brake will be activated, and the ACC system
will be canceled.

2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
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.

150STARTING 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. ice and snow, or tunnels with
reflective tiles). 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 camera in the
center of the windshield, on the forward side of the
rearview mirror. To keep the ACC system operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully clear the wind-
shield.
 Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 Do not attach or install any accessories near the
sensor, including transparent material. 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 snowplow, 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
Windshield” 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 and fog.
The ACC system may also become temporarily blinded due
to obstructions, such as mud, dirt, or ice on windshield,
driving directly into the sun and fog on the inside of glass.
In these cases, the instrument cluster display will show
“ACC/FCW Limited Functionality Clean Front Windshield”
and the system will have degraded performance.
This 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 rearview 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 Wind -
shield” 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 an authorized dealer.

23_DT_OM_EN_USC_t.book Page 150

STARTING AND OPERATING151
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
NOTE:
Aftermarket add-ons such as snowplows, lift kits, and
brush/grille bars can hinder module performance.
Ensure 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 recom -
mended.
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
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

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.

STARTING AND OPERATING153
NOTE:

The driver can disable the automatic braking function by
turning ParkSense off via the ParkSense switch. The
driver can also override automatic braking by changing
the gear or by pressing the gas pedal over 90% of its
capacity during the braking event.
 Automatic brakes will not be available if the vehicle is in
4WD Low.
 Automatic brakes will not be available if there is a fault
in the brake module.
 Automatic brakes will not be available if there is a faulted
condition detected with the ParkSense Park Assist
system or the Braking System.
 The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
 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.
 Trailer hitch ball assembly may cause false braking
events if left attached after towing.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected obstacles
when backing up in REVERSE gear.

NOTE:

 The system is designed to assist the driver and not to
substitute the driver.
 The driver must stay in full control of the vehicle's accel -
eration and braking and is responsible for the vehicle's
movements.
For limitations of this system and usage precautions, see

Ú
page 156.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
placed in the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled while in one of
these gears, 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 instrument cluster
display indicating the vehicle speed is above ParkSense
operating speed while in REVERSE. The system will become
active again if the vehicle speed is decreased to less than
approximately 6 mph (9 km/h).

PARKSENSE SENSORS
The four ParkSense sensors (six if equipped with Active
Parksense), located in the front fascia/bumper, monitor
the area in front of the vehicle that is within the sensors’
field of view, and 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 front
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/bumper. The rear sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm). These
distances depend on the location, type and orientation of
the obstacle in the horizontal direction.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within the
instrument cluster display Úpage 98. It provides visual
warnings to indicate the distance between the rear fascia/
bumper and/or front fascia/bumper and the detected
obstacle.

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, right, or center regions based on the
obstacle’s distance and location relative to the vehicle.
If an obstacle is detected in the center front region, the
display will show a single solid arc in the center front region
with no chime. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to the
vehicle and a fast chime will be heard and will change from
fast to continuous.
If an obstacle is detected in the left and/or right front region,
the display will show a single flashing arc in the left and/or
right front region and will produce a fast chime. 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 fast to continuous.
