The buttons on the right side of the steering wheel
operate the ACC system.
Adaptive Cruise Control Buttons
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility 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 condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings 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 turn the ACC system off:
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.

STARTING AND OPERATING121
To Set A Desired 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.
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 accel-
erator 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 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
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.

122STARTING AND OPERATING
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.
NOTE:
If your vehicle is at standstill longer than two
seconds, 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 incre -
ments until the button is released. The new set
speed is reflected in the instrument 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 incre -
ments 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.
When ACC Is Active
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently 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 reengage 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).
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.

22_MP_OM_EN_USC_t.book Page 122

STARTING AND OPERATING123
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 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 a slower moving vehicle is detected in the same
lane, the instrument cluster display will show the
ACC Set With Target Detected Light. The system
will then adjust 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 120.
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
force.
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 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 a 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.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

22_MP_OM_EN_USC_t.book Page 123

124STARTING AND OPERATING
NOTE:After the ACC system holds your vehicle at a stand -
still for approximately three 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 seat belt is unbuckled or the driver door
is opened, the parking brake will be activated, and
the ACC system will be cancelled.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC 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
the above message and the system will deactivate.
This 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 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 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 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 operation.
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.

22_MP_OM_EN_USC_t.book Page 124

STARTING AND OPERATING125
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC 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 and fog on the inside of glass. In
these cases, the instrument cluster display will
read “ACC 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
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 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.
SERVICE ACC WARNING
If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required”
or “Cruise 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.
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

22_MP_OM_EN_USC_t.book Page 125

126STARTING AND OPERATING
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 lane
changing example below, 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

22_MP_OM_EN_USC_t.book Page 126

STARTING AND OPERATING127
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
TRAFFIC SIGN ASSIST SYSTEM —
IF EQUIPPED
The Traffic Sign Assist (TSA) system uses a camera
mounted on the windshield, as well as map data
when the vehicle is equipped with Navigation, to
detect recognizable road signs such as:
Speed limits
School zones
No passing zones
NOTE:
The TSA system will automatically display the
road sign detected in the unit of measurement
(mph or km/h) selected within Uconnect
Settings or within the instrument cluster display.
If no speed limit signs are detected, the system
will revert to the speed limit signs that are
stored in the Navigation system.
The system always checks the traffic signs indi -
cating the current speed limit signs. The system
is able to recognize and display up to two
different road signs in the instrument cluster
display.
ACTIVATION/DEACTIVATION
The TSA System can be enabled/disabled within
the Uconnect system through the Safety/Driver
Assistance menu. System ON is signaled by road
signs shown on the instrument cluster display.
NOTE:Even if the system is OFF, the speed limit sign will
be displayed when the driver selects it in the HOME
screen.
TRAFFIC SIGN ASSIST MODES
TSA has three selectable modes of operation that
are available through the Uconnect system.
Visual
When Visual is selected, the system will alert the
driver when the current speed of the vehicle
exceeds the detected speed limit by showing a
graphic in the instrument cluster display.
Visual + Chime
When Visual + Chime is selected, the system will
alert the driver when the current speed of the
vehicle exceeds the detected speed limit by
showing a graphic in the instrument cluster
display, and by sounding an audible alert. The
audible alert will last for 10 seconds, and the
visual alert will remain on as long as the vehicle is
exceeding the speed limit.
4

22_MP_OM_EN_USC_t.book Page 127

128STARTING AND OPERATING
NOTE:Whenever an audible alert is requested by the TSA
system, the radio is also muted.
TSA Off
When the TSA system is turned off, the system will
not show any traffic signs (unless selected in the
HOME screen, which will show detected speed
limit signs), and no alerts will be issued to the
driver.
INDICATIONS ON THE DISPLAY
Detected traffic signs are shown in the instrument
cluster display, and can display any combination of
signs at one time (e.g. speed limit, speed limit and
supplemental info, and “Do Not Pass” signs)
depending on what information is available.
When a newly detected speed limit is higher than
the current speed limit, the display will update
along with an up arrow.
When a newly detected speed limit is lower than
the current speed limit, the display will update
along with a down arrow.
NOTE:Up or down arrows will be displayed for up to five
seconds.
Traffic Signs Recognized

Supplemental Information
Supplemental information may be displayed along
with a newly detected speed limit indicating
special circumstances the driver should be aware
of. Available supplemental information includes:
School
Construction
Rain
Snow
Fog
NOTE:Supplemental information will not be displayed
when the vehicle is ONLY equipped with GPS.
Speed Limit Exceeded
When the vehicle’s speed exceeds the displayed
speed limit by 3 mph (5 km/h), the speed limit sign
on the instrument cluster display will show a
red outline to alert the driver.
1 — Current Speed Limit With Supplemental Infor -
mation (School Zone)
2 — Next Speed Limit Detected
3 — No Passing Zone Detected
CAUTION!
Functionality may be limited or the system
may not work if the sensor is obstructed.
The system may have limited operation or not
work at all in weather conditions such as
heavy rain, hail, and thick fog. Strong light
contrasts can influence the recognition capa -
bility of the sensor.
The area surrounding the sensor must not be
covered with stickers or any other object.
Do not tamper or perform any operations in
the area of the windshield glass directly
surrounding the sensor.
Clean foreign matters such as bird droppings,
insects, snow or ice on the windshield. Use
specific detergents and clean cloths to avoid
scratching the windshield.
