Normal Cruise Control. The cruise control indicator
replaces the adaptive cruise
control indicator if you select
normal cruise control. The gap setting
does not display, and the system does not
respond to lead vehicles. Automatic
braking remains active to maintain set
speed. The system remembers the last
setting when you start your vehicle.
LANE CENTERING
HOW DOES LANE CENTERING
WORK
Adaptive cruise control with lane centering
uses radar and camera sensors to help
keep your vehicle in the middle of the lane
by applying continuous assistance steering
torque input toward the lane center on
highways.
Note: The adaptive cruise control gap
setting operates normally.
If you drive off-center within the lane, the
system sets and maintains that preferred
lane position. The system provides
continuous assistance steering torque
input toward the preferred position.
Note: The system can only set preferred
lane positions within the lane.
Note: If the system cancels, the preferred
position erases. On the next activation, the
system provides continuous assistance
steering torque input toward the lane center. LANE CENTERING PRECAUTIONS WARNING: Do not use the system
when towing a trailer. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use the system
if any changes or modifications to the
steering wheel have been made. Any
changes or modifications to the steering
wheel could affect the functionality or
performance of the system. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
Adaptive cruise control precautions apply
to lane centering unless stated otherwise
or contradicted by a lane centering
precaution. See Adaptive Cruise Control
Precautions
(page 352).
LANE CENTERING
REQUIREMENTS
You must keep your hands on the steering
wheel at all times.
The system only activates when all of the
following occur:
• You have adaptive cruise control with
stop and go on.
• Lane centering assist is enabled in your
information and entertainment screen.
See
Switching Lane Centering On
and Off (page 360).
• You have your hands on the steering
wheel.
• The system detects both lane
markings.
Note: If it does not detect valid lane
markings, the system stays inactive until
valid markings are available.

(If Equipped)E332905

If your vehicle starts to slow
down, you must provide steering
input to the wheel and press and
release the button to regain full system
performance.
Automatic cancellation can also occur if:
• The lane becomes too wide or too
narrow.
• The system cannot detect valid lane
markings.
• Lane markings cross over one another.
Note: The system disables until the next
key cycle if your vehicle slows down due to
driver inactivity twice within a key cycle.
LANE CENTERING INDICATORS Illuminates when you switch
lane centering on. The color of
the indicator changes to indicate
the system status.
Gray indicates the system is on but
inactive.
Green indicates the system is active and
applying steering torque assistance input
to keep your vehicle in the center of the
lane.
Amber with an audible tone and then gray
indicates a system automatic cancellation. INTELLIGENT ADAPTIVE
CRUISE CONTROL (IF EQUIPPED)
HOW DOES INTELLIGENT
ADAPTIVE CRUISE CONTROL
WORK
Intelligent adaptive cruise control
combines speed sign recognition with
adaptive cruise control to adjust the cruise
set speed to the speed limit detected by
the speed sign recognition system. As the
system detects new speed signs, the set
speed updates.
There are limitations that affect the
accuracy of the speed sign recognition
system and its ability to determine the
current speed limit. The intelligent
adaptive cruise control system and its
ability to determine the current speed limit
shares these limitations. See Speed Sign
Recognition
(page 409).
Note: The adaptive cruise control gap
setting operates normally.
INTELLIGENT ADAPTIVE CRUISE
CONTROL PRECAUTIONS WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.
INTELLIGENT ADAPTIVE CRUISE
CONTROL REQUIREMENTS
Traffic sign recognition must be enabled
for intelligent adaptive cruise control to be
active.

WHAT IS BLUECRUISE
BlueCruise keeps your vehicle centered in
the lane and offers a hands-free driving
mode in certain situations when using
adaptive cruise control.
HOW DOES BLUECRUISE
WORK
BlueCruise uses cameras to monitor your
vehicle position within a lane and applies
steering support to keep your vehicle
centered in the lane.
Using the cameras and location
information, BlueCruise allows you to
remove your hands from the steering wheel
and offers a hands-free driving mode in
certain areas.
When active, BlueCruise uses a driver
facing camera and infrared lighting to
monitor your eyes and head position to
detect if you are distracted. If the system
determines you are distracted, it alerts you
to return your eyes to the road.
Lighting area.

Camera.
B
Note: When BlueCruise is active, in certain
crash or near crash-like situations, such as
an air bag deployment or hitting a road
obstacle, camera data may record through
the vehicle event data recorder. See Event
Data (page 30). Note:
No data records under normal driving
conditions.

keeping your eyes on the road at all
times. The system is designed to be an

WHAT IS DRIVE MODE
CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK - RAPTOR
Selectable drive modes change various
electronic and mechanical settings within
your vehicle to tailor its performance and
driving characteristics to on-road or
off-road driving conditions. Steering feel
and effort, traction control, stability
control, chassis controls, powertrain
response, transmission shift points,
four-wheel driveline settings, exhaust noise
level and suspension dampening are
automatically altered to a pre-determined
setting depending upon the drive mode
that you select.
Note:
Your vehicle has diagnostic checks
that continuously monitor all systems for
proper operation. If a drive mode is
unavailable due to a system fault, your
vehicle defaults to normal mode and the
driveline remains in the four-wheel drive
setting that you last selected prior to the
system fault. Note:
Your vehicle reverts to normal mode
each time you start it. If you shut your
vehicle off in a drive mode other than
normal mode, at startup the instrument
cluster screen displays a pop-up asking if
you would like to return to your last used
drive mode. If you select yes to the pop-up,
your vehicle returns to the last selected drive
mode and the default four-wheel driveline
setting associated with that drive mode. If
you select no, your vehicle remains in normal
mode and the default four-wheel driveline
setting associated with that drive mode. If
you do not select yes or no, the pop-up
message times out, your vehicle remains in
normal mode, and the four-wheel driveline
setting remains in its last used setting.
Note: Do not use the electronic locking
differential on dry, hard surfaces. Doing so
produces excessive noise, vibration and
increases tire wear. See Electronic Locking
Differential (page 301).

Note: Your vehicle reverts to normal mode
each time it is started. If you shut your
vehicle off in a drive mode other than
