The Driver Alert Control (DAC) function is designed to help alert the driver to erratic behavior, e.g. if the driver is distracted or shows signs of fatigue.

The objective of the function is to detect slowly deteriorating driving behavior and is primarily intended to be used on major roads.

The function is not intended for use in city traffic. DAC is activated when the vehicle's speed exceeds 65 km/h and remains active as long as speeds are above 60 km/h.
