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.
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 DAC function has issued a warning or not.
The function uses the vehicle's camera and radar sensor, which has certain general limitations.
