Warning
A driving pattern may not change despite driver fatigue, e.g., if a function such as Pilot Assist is being used, which means that DAC will not provide a warning. It is always very important to stop and take a break at the first sign of driver fatigue, even if the system has not provided a warning.
In certain situations, DAC may provide warnings even if the driver’s driving pattern has not become erratic:
- in strong crosswinds
- on grooved road surfaces.
Note
DAC uses the vehicle's camera, which has certain general limitations. See the article "Camera limitations" for additional information.
