STARTING AND OPERATING143
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 appears 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 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
ACC Set With Target Detected Indicator Light, and the
system will adjust the 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 141.
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 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 side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill while
following a vehicle ahead, your vehicle will resume motion,
without any driver interaction, if the vehicle ahead starts
moving within two seconds of your vehicle coming to a
standstill.
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.

144STARTING AND OPERATING
NOTE:
If your vehicle is at a standstill for longer than two
seconds, the system will hold brake pressure for up to
10 minutes. If no driver action is taken after the
10 minutes, the Electric Park Brake will be applied and
the ACC system will cancel.
While ACC is holding your vehicle at a standstill (or the
vehicle is traveling below 3 mph (5 km/h), and the
driver seat belt is unbuckled or the driver door is
opened, the Electric Park Brake will be applied and the
ACC system will cancel.
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 this 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 malfunction or failure and
require a sensor realignment.
If the sensor or front end of the vehicle is damaged due
to a collision, see your 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 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 operation.
“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.
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.
23_WS_OM_EN_USC_t.book Page 144
Page 147 of 396

STARTING AND OPERATING145
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 Windshield”
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
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.
ACC Hill Example

146STARTING 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
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
23_WS_OM_EN_USC_t.book Page 146
Page 149 of 396

STARTING AND OPERATING147
NOTE:
The TSA system will automatically display the
detected road sign using 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 indicating
the current speed limit. The system is able to recognize
and display up to two different road signs in the instru -
ment cluster display. These road signs can be found on
the Driver Assist page.
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 Úpage 197.
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.
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 of which the driver should be aware.
Available supplemental information includes:
School
Construction
Rain
Snow
Fog
NOTE:Supplemental information will not be displayed when the
vehicle is ONLY equipped with GPS.1 — Current Speed Limit With Supplemental Information
(School Zone)

148STARTING AND OPERATING
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
90 mph (145 km/h).
For ACC system operating instructions and system
limitations, see
Úpage 139.
NOTE:
The driver should always obey traffic laws and speed
limits. Never drive above applicable speed limit restric -
tions.
The driver can override ADA at any time by braking,
accelerating, or steering the vehicle.
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 by utilizing the Blind Spot Monitoring
sensors.
Two types of Active Driving Assist systems are available:
Base ADA system
Hands-Free ADA system
Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the steering
wheel to measure driver attentiveness, and requires that
the driver have their hands on the steering wheel at all
times. The system will generally aim to keep the vehicle centered
in the lane, but when the driver turns the steering wheel
(e.g. to move farther away from a large vehicle in an
adjacent lane) the system will reduce its control and enter
"co-steering" mode. While in co-steering mode, the system
will provide reduced assistance and allow the driver to
control the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system will
require a few seconds to fully resume lane centering
assistance, especially during curves.
Hands-Free Active Driving Assist System — If Equipped
The Hands-Free ADA system uses sensors within the
steering wheel and a driver monitoring camera located on
top of the steering column to monitor driver attentiveness.
The Hands-Free ADA system allows the driver to remove
their hands from the steering wheel when engaged, but
requires that the driver continue to pay attention to the
road.
The Hands-Free ADA system will also change lanes when
a turn signal is activated if the adjacent lane in the
direction indicated is clear of another vehicle, and lane
markings are detected (noted by a dashed line in the
direction of the available lane change). The system uses
sensors, including Blind Spot Monitoring (BSM) sensors,
to determine if a lane change is possible. If the assisted
lane change is in progress, a green arrow will appear. If a
lane change is requested but the direction indicated is not
possible, a yellow arrow will appear. Once conditions are
clear, the arrow will turn green and the assisted lane
change will begin.
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 capability 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.

STARTING AND OPERATING149
(Continued)
Additionally, Hands-Free ADA will slow the vehicle down
when approaching and going through sharp curves.
Assisted Lane Change (Green Left Arrow)
Extended Auto Resume
If equipped with Hands-Free ADA and the system brings
your vehicle to a stop while following the vehicle ahead,
your vehicle will automatically resume driving without
driver input when the path in front of the vehicle is clear
and the driver is attentive. The path in front of the vehicle
is determined to be clear based on the forward facing
camera, front radars, and front ultrasonic sensors. If the vehicle in front does not start moving after
10 minutes, the Electric Park Brake (EPB) will be applied
and the system will cancel.
NOTE:
The Hands-Free Active Driving Assist system is only
available on approved compatible roadways and
requires an active subscription through the Uconnect
Connected Services package. If the ADA on/off button
is pushed without an active subscription, the instru -
ment cluster display will show the message “Active
Driving Assist Unavailable Update Subscription”. Refer
to the Uconnect Owner’s Manual Supplement for
further information.
If previously disabled, activating the Hands-Free Active
Driving Assist system will also activate the Forward
Collision Warning and Pedestrian Emergency Braking
systems
Úpage 250.
If the vehicle is equipped with the Uconnect Connected
Services package, additional data may be collected
through the Connected Services system. This includes
information about the vehicle’s operation, a collision
involving the vehicle, the use of the vehicle and its
features, and in certain situations, the location and
approximate GPS speed of the vehicle. Refer to the
Uconnect Owner’s Manual Supplement for Terms and
Conditions and Privacy Statements.
The driver monitoring camera may record images of the
driver during certain crash, or near crash-like situa -
tions. To retrieve the images recorded by the camera,
special equipment is required and access to the
vehicle or the camera is needed.
Vehicle data may be read from the Hands-Free ADA
system with special equipment and access to the
vehicle or the Event Data Recorder (EDR).WARNING!
The driver is always responsible for determining if a
lane change is safe. Failure to follow this warning can
result in a collision and death or serious personal
injury.
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.
Some states and local laws may require hands to be
kept on the steering wheel at all times. For vehicles
equipped with the Hands-Free ADA system, ONLY
remove your hands from the steering wheel if the
Hands-Free system is engaged, it is safe to do so, and it
is permitted by state and local laws.4
