Driver Alert Control limitations

Driver Alert Control (DAC) functionality may
be reduced in certain situations.
In certain situations, the system may provide a
warning even if it has not detected a change in
driving behavior, e.g.:
in strong crosswinds
•
on grooved road surfaces.
•
WARNING
In certain cases, driving behavior might not
be affected despite the driver's fatigue –
when using the Pilot Assist* function –
resulting in the driver not getting a warning
from DAC.
It is therefore very important to always
stop and take a break at the slightest sign
of fatigue, regardless of whether the func-
tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

with an unobserved vehicle.

detect obstacles while backing up.
CTA is primarily designed to detect vehicles,
but in certain cases can also detect pedes-
trians or smaller objects such as bicycles.
The function is only active when the vehicle is
moving backward or reverse gear is engaged.
