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, regardless of whether the function has given a warning.
This function uses the car's camera and radar units, which have certain general limitations.
