WARNING
:
In some cases, driving behaviour is not affec-
ted despite driver fatigue – e.g. when using
the Pilot Assist function – resulting in the
driver not getting a warning from DAC.
Driver Alert
It is therefore important to always stop and
take a break at the slightest feeling of fatigue,
whether the DAC function ha given a warning
to
or not.
NOTE
This function uses the car's camera and radar
units, which have certain general limitations.
