Driver Alert Control
The Driver Alert Control (DAC) function isdesigned to help capture the driver becomeaware of erratic behavior, e.g. if the driver is dis-tracted or showing signs of fatigue.
The objective of DAC is to detect slowly deterio-rating driving behavior and is primarily intended tobe used on major roads. The function is notintended for use in city traffic.
DAC is activated when the vehicle's speedexceeds 65 km/h (40 mph) and remains activeas long as speeds are above 60 km/h (37 mph).
DAC detects the vehicle's position in the traffic lane.
A camera monitors the traffic lane's marker linesand compares the direction of the road with thedriver's movements of the steering wheel.
The vehicle is moving erratically in the lane.
If driving behavior becomesconsiderably erratic, the driverwill be alerted by this symbol inthe instrument panel, an audi-ble signal and the messageTime for a break.
If the vehicle is equipped with SensusNavigation* and the Rest Stop Guidance func-tion is activated, a suitable place to take a breakwill also be suggested (see section “Selectingguidance to a rest stop if a Driver Alert Controlwarning has been given”).
The warning will be repeated after a short time ifdriving behavior does not improve.

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may bereduced in certain situations.
In certain situations, the system may provide awarning even if it has not detected a change indriving behavior, e.g.:
in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not beaffected despite the driver's fatigue – whenusing the Pilot Assist function – resulting inthe driver not getting a warning from DAC.
It is therefore very important to always stopand take a break at the slightest sign of fati-gue, regardless of whether the DAC functionhas issued a warning or not.

NOTE
The function uses the vehicle's camera unit,which has some general limitations – see thesection "Camera unit limitations".
