Limitations of Driver Alert Control

The Driver Alert Control (DAC) function may have limitations in certain situations.
In some cases the system may issue a warning despite driving ability not deteriorating, for example:
  • in strong side winds
  • on rutted road surfaces.


In some cases, driving behaviour is not affected despite driver fatigue – e.g. when using the Pilot Assist function – resulting in the driver not getting a warning from DAC.

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 or not.


The function uses the car's camera unit, which has some general limitations, see the "Limitations for camera unit" section.
