When active drive assist is providing
hands-on driving and detects you are not
looking at the road for a certain period of
time, the system alerts you to return your
eyes to the road.
If you do not react to the warnings, active
drive assist cancels, quickly activates and
releases the brakes, and slows your vehicle
down to low speeds while maintaining
steering control.
If your vehicle slows down and you resume
control, a message appears to prompt you
to press the accelerator pedal to allow the
system to resume.
Note: The system disables until the next
key cycle if repeated inactivity is detected.
ACTIVE DRIVE ASSIST
AUTOMATIC CANCELLATION
When an external condition cancels active
drive assist, for example, no lane markings
available, a tone sounds and a message
appears in the instrument cluster.
E308130
If your vehicle starts to slow
down, you must take control of
steering and press and release
the button to reactivate active drive assist.
System cancellation can also occur if:
The lane becomes too narrow.
The system cannot detect valid lane
markings.
Lane markings are crossed.
Your eyes are not on the road or your
hands are not the steering wheel.
If you have your hands on the steering
wheel and your eyes are on the road when
the feature is active and a cancellation
occurs, the system sounds a tone and
displays a cancelled graphic in the
instrument cluster.
If you are not paying attention to the road
or your hands are not on the steering wheel
and a cancellation occurs, the system will
display a message and a tone sounds until
you resume control. If you do not resume
control in time, active drive assist quickly
activates and releases the brakes, and
slows your vehicle down to low speeds
while maintaining steering control. If your
vehicle slows down and you resume
control, a message appears to prompt you
to press the accelerator pedal to allow the
system to resume.
Note: The system disables until the next
key cycle if repeated inactivity is detected.
