FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system provides
enhanced vehicle response and increased ease of
maneuverability in tight spaces. The power
steering system adapts to different driving
conditions. If the electric power steering system
experiences a fault that prevents it from providing
assistance, you will still have the ability to steer the
vehicle manually.
NOTE:Alternate electric power steering efforts (Normal,
Comfort and Sport) can be selected through the
Uconnect System Ú page 204. If SPORT mode is
selected, steering efforts are optimized for sporty
driving.
If the Electric Power Steering warning
icon is displayed and the “Service Power
Steering” or the “Power Steering Assist
Off – Service System” message is
displayed within the instrument cluster display,
this indicates the vehicle needs to be taken to the
dealer for service Ú page 108.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

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.
