Volvo XC90: Driver support / Driver Alert Control limitations

Driver Alert Control (DAC) functionality may be reduced in certain situations.

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.

WARNING

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 function has issued a warning or not.

NOTE

The function uses the vehicle's camera and radar sensor, which has certain general limitations.
