Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel
operate the ACC system.

Adaptive Cruise Control Buttons

Driving Assist Menu
The instrument cluster display will show the
current system settings for Adaptive Cruise Control
(ACC), Active Lane Management (ALM), and the
Active Driving Assist (ADA) systems. The
information it displays depends on ACC, ALM, and
ADA system statuses.
Pushing the Adaptive Cruise Control (ACC) buttons
will display one of the following messages in the
instrument cluster display:
Adaptive Cruise Control Ready
When ACC is activated but the vehicle speed
setting has not been selected, the display will read
“Adaptive Cruise Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button is pushed,
the display will read “ACC: XX mph (km/h)”.
When ACC is set, the set speed will show in the
instrument cluster display.
The ACC screen may display once again if any of
the following ACC activity occurs:
System Cancel
Driver Override
System Off
ACC Proximity Warning
ACC Unavailable Warning
Will bring the vehicle to a complete stop
and hold the vehicle in the stop position
for approximately 10 minutes when
following a vehicle ahead. If the vehicle
ahead does not start moving within
10 minutes, the parking brake will be acti -
vated, and the ACC system will be
canceled.
You should not utilize the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (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

STARTING AND OPERATING147
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 Ú page 144.
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 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
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.
NOTE:
If your vehicle is at a standstill for longer than
two seconds, the system will hold brake pres
-
sure 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.
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.

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 Ú page 142.
NOTE:
The driver should always obey traffic laws and
speed limits. Never drive above applicable
speed limit restrictions.
1 — Current Speed Limit With Supplemental Infor
-
mation (School Zone)
2 — Next Speed Limit Detected
3 — No Passing Zone Detected
CAUTION!
Traffic Sign Assist is designed to assist the
driver and not to substitute the driver. It is the
driver’s responsibility to continue to monitor
the vehicle speed.
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. For
glass cleaning recommendations, see
Ú page 395.
CAUTION!

23_WL_OM_EN_USC_t.book Page 152

STARTING AND OPERATING153
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.
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.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.

154STARTING AND OPERATING
(Continued)
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 road
-
ways. Please consult the Jeep® website for
further details on compatible roadways.
The Hands-Free Active Driving Assist system
requires an active subscription through the
Jeep® Connect (Uconnect Connected Services)
package. If the ADA on/off button is pushed
without an active subscription, the instrument
cluster display will show the message “Active
Driving Assist Unavailable Update Subscrip -
tion”. 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 Ú page 261.
If the vehicle is equipped with the Jeep®
Connect (Uconnect Connected Services)
package, additional data may be collected
through the Jeep® Connect (Uconnect
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 situa -tions, 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 situations. To retrieve the
images recorded by the camera, special equip
-
ment 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 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.
You should turn off the Active Driving Assist
systems:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather or low visibility condi -
tions (e.g. rain, snow, fog, sleet, dust), or
adverse road conditions (e.g. heavy traffic,
worn or missing lane markings, etc.).
When entering a highway on-ramp or exiting
an off-ramp.
When driving on roads that are icy, snow
covered, or slippery.
When driving during difficult or uncertain
conditions.
