SYSTEM OPERATION/LIMITATIONS
The Base Active Driving Assist and Hands-Free
Active Driving Assist systems DO NOT:
Warn or prevent collisions with other vehicles
Steer your vehicle around stopped vehicles,
slower vehicles, construction zones or equip -
ment, pedestrians, or animals
Respond to traffic lights or stop signs
Merge onto highways or exit off ramps
Change lanes (exception: Hands-Free, only
when initiated by the driver)
React to cross traffic
NOTE:Adaptive Cruise Control (ACC) is a core component
of ADA. For ACC system limitations Ú page 142.
The Active Driving Assist system may have limited
or reduced functionality when one of the following
conditions occur:
The vehicle’s radar sensors and/or forward
facing camera is damaged, covered,
misaligned, or obstructed (e.g. by mud, ice,
snow, etc.)
WARNING!
Active Driving Assist is an SAE Level 2 Driver
Assist feature, requiring driver attention at all
times. To prevent serious injury or death:
Always remember that the Active Driving
Assist system is a convenience system that
cannot accurately detect all situations.
Complete attention is always required while
driving, even when using the Active Driving
Assist system.
Always remain alert and be ready to take
control of the vehicle in the event that the
Active Driving Assist system deactivates, or
otherwise lacks full functionality as described
further before and after this statement.
Always keep your hands on the steering wheel
when the Base Active Driving Assist system is
activated.
Always keep your eyes on the road when the
Hands-Free Active Driving Assist system is
activated.
Maintain a safe distance from other vehicles
and pay attention to traffic conditions.
Do not use a hand held device when either
Base, or Hands-Free Active Driving Assist
system is engaged.
Always pay attention to the road when the
Hands-Free Active Driving Assist system is
engaged. The Active Driving Assist system will
not steer to avoid safety hazards, construction
zones, objects, or road impediments. You
need to take control to steer and brake the
vehicle in such situations, and when merging
into traffic, exiting the highway, making a turn
for crossing traffic, or stopping for traffic
control devices.
Do not place any objects on the steering wheel
(e.g. steering wheel covers) which could inter -
fere with the hand detection sensors.
WARNING!

STARTING AND OPERATING171
Selection Of The Maneuver Side
Use the direction indicators to choose the direction
that you want to perform the maneuver. Use the
right arrow indicator to perform the maneuver to
the right side and use the left arrow indicator to
perform the maneuver to the left.
During the maneuver, the system instructs the
driver to shift to REVERSE, and operate the turn
signal in the direction you want to exit. Let go of the
steering wheel and use the brake or accelerator
pedals as instructed, while the system handles the
steering automatically for exiting the parking
space. If the driver continues to carry out a
voluntary or involuntary action on the steering
wheel during the exit maneuver (touching or
holding the steering wheel to prevent its
movement), the maneuver will be interrupted.

Shift To Reverse Then Move Backward Shift To Drive Then Move Forward

End Of Maneuver
The semi-automatic maneuver ends when the
display shows the message of a completed
maneuver. At the end of the maneuver, the system
gives back the vehicle control to the driver.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and to measure vehicle position within
the lane boundaries. It also uses the Blind Spot
Monitoring (BSM) sensors to detect vehicles in
adjacent lanes while the driver is preparing to
change lanes. The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle approaches (or crosses) the lane marking
with no turn signal applied, and the blind spot zone
is not occupied, the ALM system provides warnings
to prompt the driver to remain within the lane
boundaries. These warnings include a visual
warning in the instrument cluster along with
steering assist torque (if configured in Uconnect
Settings).
If the driver crosses the lane marking, the system
will either guide the vehicle back to the center of
the lane, provide a vibration in the steering wheel,
or both, depending on radio settings.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change, and a vehicle is detected in the BSM zone
on that side of the vehicle, the ALM system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.NOTE:
The system will suppress visual warnings,
steering vibration (if selected in radio settings),
and steering assistance (if selected in radio
settings) when the driver activates the turn
signal, the blind spot zone is clear of vehicles,
and a lane change is occurring.

23_WL_OM_EN_USC_t.book Page 171

172STARTING AND OPERATING
If the Blind Spot Monitoring (BSM) system
detects a vehicle in the adjacent lane, and the
turn signal is applied in that direction, the BSM
LED on the mirror will flash. If the driver
continues to attempt the lane change, steering
wheel torque will be provided to keep the
vehicle within its lane markings.
The driver may manually override the steering
assist warning by applying force to the steering
wheel at any time.
When only a single lane marking is detected and
the driver drifts across the lane marking (no turn
signal applied), the Active Lane Management
system provides a visual warning in the instrument
cluster, as well as a steering assist torque (if
configured in Uconnect Settings), to prompt the
driver to remain within the lane boundaries. If the
driver continues to drift out of the lane, the system
provides a flashing visual warning through the
instrument cluster display as well as a haptic
steering wheel vibration (if configured in Uconnect
Settings) when the vehicle crosses the lane
boundary.
NOTE:When operating conditions have been met, the
Active Lane Management system will monitor if the
driver’s hands are on the steering wheel and
provides an audible and visual warning to the
driver if removed. The system will cancel if the
driver does not return their hands to the wheel.
TURNING ACTIVE LANE MANAGEMENT
O
N OR OFF
The Active Lane Management button is
located on the switch panel above the

NOTE:The Active Lane Management system will retain
the last system state on or off from the last ignition
cycle when the ignition is placed in the ON/RUN
position.
ACTIVE LANE MANAGEMENT WARNING
M
ESSAGE
The Active Lane Management system will indicate
the current lane drift condition through the
instrument cluster display.
When the system is on, the lane lines are gray
when both of the lane boundaries have not been
detected.
System On (Gray Lines)

Left Lane Departure — Only Left Lane Detected
When the system is on and only the left lane
marking has been detected, and the system is
ready to provide visual warnings in the instru-
ment cluster display and a vibration and/or
steering assist warning in the steering wheel if a
lane departure occurs, the left lane line will be
green.
When the system senses the lane line has been
approached (but not crossed), the left lane line
will change to solid yellow and the system will
provide a haptic steering wheel vibration and/or
steering assist torque (if programmed in
Uconnect Settings).
When the system senses the lane line is being
crossed, the left lane line will change to flashing
yellow.

STARTING AND OPERATING173

Lane Crossed (Flashing Yellow Line)

NOTE:The Active Lane Management system operates
with similar behavior for a right lane departure
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
When the system is on, the lane lines turn from
gray to green to indicate that both of the lane
markings have been detected. When both lane
markings have been detected, the system is
ready to provide visual warnings in the instru -
ment cluster display and a vibration and/or
steering assist warning in the steering wheel if a
lane departure occurs.
Lanes Sensed (Green Lines)

When the system senses a lane drift situation,
the left lane line turns solid yellow. At this time,
steering assist warning is applied to the steering
wheel in the opposite direction of the lane
boundary.
For example: If approaching the left side of the
lane, the steering wheel will turn to the right.

Lane Drift (Solid Yellow Line)
When the system senses the lane line is being
crossed, the left lane line changes from solid
yellow to flashing yellow (on/off). At this time,
vibration is applied to the steering wheel.
For example: If approaching the left side of the
lane, the steering wheel will turn to the right.

DROWSY DRIVER DETECTION (DDD) —
I
F EQUIPPED
DDD detects when the driver is feeling fatigued
and warns the driver to pull over and take a break.
To Activate/Deactivate

DDD can be activated and deactivated through the
Uconnect system by selecting the following in order:

1. “Safety & Driving Assistance”

2. “Drowsy Driver Detection”
System Operation
Using feedback obtained from the driver’s steering
patterns, any buttons/switches that are pressed,
and from the front camera, the system implements
two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 100 mph
(160 km/h).
If the driving style indicates that the driver is
unable to follow the road trajectory and respect the
horizontal lane markings while within the operating
speed range of the system, a pop up will display on
the instrument cluster display to suggest that the
driver should stop for a break. An audible signal
will also sound.
If the driver accepts the suggestion provided by the
system by pushing the “OK” button on the left side
of the steering wheel, the message will disappear
from the display.
If the driver does not acknowledge the warning, it
will be displayed for 60 seconds and then
disappear.
NOTE:In the event of a DDD system failure, a dedicated
message will appear in the instrument cluster
display.

DDD Warning Message

REAR SEAT REMINDER ALERT (RSRA)
RSRA alerts you through a visual and auditory
notification of the possible presence of an object,
passenger, or pet in the rear seats if a rear door
was opened up to 10 minutes before the ignition
was placed in the ON/RUN position. RSRA does not
directly detect objects, passengers, or pets in the
rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on
the instrument cluster display and sounds an
auditory alert upon the driver placing the ignition in
the OFF position to exit the vehicle.
To enable or disable RSRA, see Ú page 204.WARNING!
The DDD system is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. Always drive alert and get
plenty of rest before driving. If you experience
fatigue while driving, do not wait for the DDD to
intervene with a warning. Choose a safe and
secure location where you can pull over safely
for a break. Only return to the road when you are
in the right physical and mental condition to
prevent endangering yourself and others.
