fully/partially obstructed or poorly positionedsigns
signs partially or fully covered by frost, snowand/or dirt
digital road maps97 that are outdated, incor-

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.

WARNING
The Driver Alert Control function is sup-plementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
Driver Alert Control must not be used toextend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
Driver Alert Control is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.

WARNING
An alarm from Driver Alert Control should betaken very seriously since a sleepy driver isoften not aware of their own condition.
If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as possi-ble and rest.
Studies have shown that it is just as danger-ous to drive while tired as it is to drive underthe influence of alcohol or other stimulants.

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".
