STARTING AND OPERATING87

Distance Settings

To adjust the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting decreases by one bar
(longer). Once the longest setting is reached, if the
button is pushed again it will be set to the shortest
setting available.
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 84.
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.
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.

88STARTING AND OPERATING
Display Warnings And Maintenance
RADAR SENSOR UNAVAILABILITY 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 can
be still enabled.
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.
“ACC LIMITED FUNCTIONALITY CAMERA
BLOCKED” WARNING
The “ACC Limited Functionality Camera Blocked”
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 Camera Blocked” 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.
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_VF_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
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 Camera Blocked”
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

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

22_VF_OM_EN_USC_t.book Page 89

90STARTING AND OPERATING
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

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

STARTING AND OPERATING91
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.
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.

22_VF_OM_EN_USC_t.book Page 91

92STARTING AND OPERATING
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
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.
ACTIVE DRIVING ASSIST SYSTEM —
IF EQUIPPED
OPERATION
The Active Driving Assist (ADA) system is combined
with the Adaptive Cruise Control (ACC) system, and
centers the vehicle in the driving lane while
traveling at speeds up to 93 mph (150 km/h).
Just like ACC, ADA will maintain a set speed as long
as the set distance between your vehicle and the
vehicle in front is maintained. ADA will also keep
your vehicle centered between the lane lines, and
monitor for other vehicles in adjacent lanes.
ADA uses sensors within the steering wheel to
monitor driver attentiveness. ADA requires the
driver’s hands on the steering wheel at all times.
1 — Current Speed Limit With Supplemental
Information (School Zone)
2 — No Passing Zone Detected
3 — Next Speed Limit Detected
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system disables.
Always keep your hands on the steering wheel
when the Active Driving Assist system is acti
-
vated.
Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.

ADA will become enabled and then engaged (once
all other conditions are met).

3. If ACC was not enabled before pushing the ADA on/off button, push the SET (+) button or the
SET (-) button and release when the desired
driving speed is shown in the instrument
cluster display.
4. If desired, adjust the ACC distance setting by pushing the Distance Setting button.
When all system conditions are met as described
in “System Engagement Conditions” in the next
section, the system will engage and the steering
wheel image in the display will change to green.

Active Driving Assist Engaged (Steering Wheel Green)

WARNING!

The Active Driving Assist (ADA) system is a
convenience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road traffic, weather
conditions, vehicle speed, distance to the vehicle
ahead, position in the lane compared to other
vehicles, and brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
You should turn off the Active Driving Assist system:

When driving in fog, heavy rain, heavy snow,
sleet, and complex driving situations (i.e., in
construction zones).
When entering a highway off ramp, when
driving on roads that are icy, snow covered, or
slippery.
When circumstances do not allow safe driving.

94STARTING AND OPERATING
NOTE:Along with the color change of the steering wheel
image, the “glow” effect of the instrument cluster
display will also change to green when ADA is
engaged.
System Engagement Conditions
The following conditions must be met before the
system will engage:
Active Driving Assist system is enabled
ACC is engaged
System detects visible lane markings
Vehicle is traveling below 93 mph (150 km/h)
Vehicle is centered in lane
Turn signal is not activated
Vehicle is not in a tight curve
Driver has hands on steering wheel
NOTE:For the system to detect the driver’s hands on the
steering wheel, the wheel must be gripped on the
outside. Gripping the inside areas of the steering
wheel will not satisfy the hands-on condition to
engage the system.
Do Not Grip Inside Of Steering Wheel

System Deactivation
The system will be deactivated in any of the
following situations:
If the system has detected driver inattentive -
ness, and has gone through all escalation warn -
ings after hands are no longer detected on the
steering wheel
If lane markings are no longer detected
If the Active Driving Assist on/off button is
pushed again (ADA will turn off)
If a turn signal is used
If the driver applies torque to the steering wheel

If the vehicle speed exceeds 93 mph (150 km/h)

If the ACC system is deactivated

If the Forward Collision Warning (FCW) system
becomes active and is providing warnings/braking

NOTE:
Pushing the Active Driving Assist on/off button
will turn the system off. All other deactivation
conditions will place the system back into the
“enabled” state with the steering wheel indi -
cator displayed in grey until all engagement
conditions are met again.
When the system is deactivated, the system
status indicator lights will turn off, Active Lane
Management will return to its previous state,
and ACC will disable.
INDICATIONS ON THE DISPLAY
The Active Driving Assist system status can always
be viewed in the instrument cluster display, and
status changes are shown by changes in color of
the system’s indicator lights.
As the system detects driver inattentiveness as
previously described Ú page 92, the system
status indicator lights will change from green, to
yellow, to red, while the steering wheel icon on
the display moves up the screen to the center.
The following indicators will change in color as
warnings to the driver escalate:
Active Driving Assist Indicator (steering wheel
icon in the instrument cluster display)
Glow effect of the instrument cluster display
