NOTE:
•
Pushing the Active Driving Assist on/off button or
deactivating ACC will turn the system off. All other
deactivation conditions will place the system back
into the "enabled" state with the steering wheel indi-
cator displayed in white until all engagement condi-
tions are met again.
•
When the system is deactivated, the system status
indicator lights will turn off, the LaneSense system
will return to its previous state, and ACC will disable.
INDICATIONS ON THE DISPLAY
The Active Driving Assist system status can always be
viewed in the instrument cluster display, and status
changes are shown by changes in color of the system's
indicator lights.
As the system detects driver inattentiveness as previ-
ously described
page 117, the system status indi-
cator lights will change from green, to yellow, to red.
The following indicators will change in color as warnings
to the driver escalate:
•
Active Driving Assist Indicator (steering wheel icon in
the instrument cluster display)
•
Glow effect of the instrument cluster display
If driver driver's hands are not returned to the steering
wheel, the system will deactivate.
Active Driving Assist Indicators Are Off
•
ADA is not turned on/enabled by the driver.
Active Driving Assist Indicators Are White
•
ADA is turned on/enabled by the driver, but the sys-
tem is not actively steering or providing Cruise Con-
trol for the vehicle.
Active Driving Assist Indicators Are Green
•
The system detects driver attentiveness and is actively
steering and providing Cruise Control for the vehicle.
Active Driving Assist Indicators Are Yellow
•
Driver inattentiveness has been detected, warning
the driver to place hands on the steering wheel.
Active Driving Assist Indicators Are Red
•
Driver inattentiveness is still being detected, or driver
take-over is being requested, warning the driver to place
hands on the steering wheel. This warning is also issued
when the system has detected a tight curve and is
warning the driver to take control.
NOTE:
The driver MUST replace hands on the steering wheel
and take control of the vehicle when the system is
deactivated.
MINIMUM RISK MANEUVER
When the vehicle begins the hands-off steering wheel
warning escalation, previously described, the system
will initiate the Minimum Risk Maneuver for bringing the
vehicle to a stop.
After 23 seconds from the initial absence of the hands
on the steering wheel, the Adaptive Cruise Control (ACC)
system will apply a brake jerk to warn the driver to take
vehicle control. If, after another 3 seconds the driver
does not take the control of the vehicle, the system will
apply a second brake jerk.
If the absence of hands on the steering wheel persists,
the system will apply automatic braking to bring the
vehicle to the stop and activate the vehicle's hazard
warning lights. After the vehicle is stopped, the system
will unlock the doors (if previously locked).
STARTING AND OPERATING
NOTE:
If the driver takes control of the vehicle during the Mini-
mum Risk Maneuver by placing hands on the steering
wheel or pressing the accelerator, the system Minimum
Risk Maneuver will be canceled, and the ADA system
will resume normal function.
SYSTEM STATUS
Along with changes in the system's indicator lights (green,
yellow, and red), the system can also issue several accom-
panying warnings intended to provide the driver with enough
time to react, avoid or mitigate a potential collision.
•
Two haptic brake jerk warnings will be issued (red
warning light is being issued).
•
A steering wheel vibration warning (if enabled) will
occur if the vehicle crosses a lane marker, for
example, when driving on a tight curve. The steering
wheel vibration feature can be turned on or off
within the Uconnect system
page 142.
SYSTEM OPERATION/LIMITATIONS
WARNING!
The DDD system is an aid for driving and does not
relieve the driver of the responsibility of driving the
vehicle. If you experience fatigue while driving, pull
over safely for a break without waiting for the DDD
warnings. Only return to the road when you are in the
right physical and mental condition to prevent endan-
gering yourself and other drivers.
