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

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.
