If the vehicle exceeds a detected speed limit with theSpeed Warning function acti-vated, the driver is given aspeed warning when the vehi-cle is approaching a speedcamera if the navigation map
for the vehicle's current location contains infor-mation on speed cameras.
For more information on Speed Warnings in con- junction with speed cameras, see "Road SignInformation with Speed Warning and settings"and "Road Sign Information limitations".
NOTE
• For an audible alert to be provided if the speed is exceeded, the Speed Limit
Warning function must be activated and
the Road Sign Audio Warning sub-
function must be On. Audible alerts are
provided if the vehicle's speed exceeds the speed displayed by RSI in the instru-ment panel.
• Information about speed cameras on thenavigation map is not available for allmarkets/areas.

Driver Alert Control
The Driver Alert Control (DAC) function is designed 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 speed exceeds 65 km/h (40 mph) and remains activeas long as speeds are above 60 km/h (37 mph).
A camera monitors the traffic lane's marker lines and compares the direction of the road with thedriver's movements of the steering wheel.
If the driving behavior becomes noticeably erratic, the driver willbe alerted by this symbol in theinstrument panel and the mes- sage
Time for a break
soon?.
If driving behavior does not improve but instead becomes even more erratic, the driver will bealerted by the same symbol in the instrument panel, an audible signal and the message
Time
for a break.
If the Rest Stop Guidance function is activated
in Sensus Navigation * when the Time for a
break warning is given, suggestions will also be
provided for suitable places to take a break.

The warnings will be repeated after a short time if driving 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 be taken 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 be reduced in certain situations.
In certain situations, the system may provide a warning 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 be affected 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 stop and 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".

) is designed to
actively steer the vehicle on freeways, highways and other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.
Lake Keeping Assistance steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65-200 km/h (40-125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavailable and go into standby mode. The function willbecome available again when the road becomessufficiently wide.
