STARTING AND OPERATING85
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 Adap -
tive cruise control light will flash and, if a target
is detected by the sensor, the target graphics
will also flash.
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.
Desired Driving Speed Through A Detected
Speed Sign
The Active Driving Assist (ADA) system allows the
driver to set the detected speed sign Úpage 91 as
the new desired driving speed. The Traffic Sign
Assist (TSA) system will suggest the new detected
speed sign on the cluster and then the driver can
decide to confirm the speed sign capturing by
pressing the RES (resume) button.
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 braking temperature exceeds normal range
(overheated)
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
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.
WARNING!
In Fixed Speed Cruise Control mode (ACC not
enabled), 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.4

22_VF_OM_EN_USC_t.book Page 85

86STARTING AND OPERATING
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 increments 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 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.
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 tempera -
ture 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.
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_VF_OM_EN_USC_t.book Page 86

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

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.
