Curve Speed Assist (CSA) *44
Curve Speed Assist can help the driver
reduce speed before sharp turns if the preset speed for the driver support function Adap- tive Cruise Control * or Pilot Assist * is deter-
mined to be too high.
This assessment is performed using informa- tion from map data in the vehicle's navigation system, Sensus Navigation *. After the turn,
the vehicle will resume the previously set speed.
As the function reduces thevehicle's speed, this symbolwill be displayed in the instru-ment panel.
The driver can cancel the function at any time by braking or using the accelerator pedal.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.

speed limit has been exceeded or if there are speed cameras nearby.
Example of speed camera and speed limit informa- tion in the instrument panel.
Speed Limit WarningWhen Speed Warning is acti- vated, the symbol for the cur-rent speed limit in the instru- ment panel 79
will flash tem-
porarily if that speed is excee- ded.
The driver can be alerted if the vehicle is exceeding a detected speed limit and isapproaching a speed camera.
Speed Limit Warning warns the driver if the
vehicle's speed has exceeded the applicable speed limit or the preset Speed Limiter speed.The warning will be repeated once afterabout 1 minute in that speed limit area if thedriver does not slow down. A new warning and message indicating that the speed limit has been exceeded will be pro-vided only when the vehicle has entered anew/different speed limit area.

Driver Alert Control
The Driver Alert Control (DAC) function is designed to help alert the driver to erraticbehavior, e.g. if the driver is distracted orshowing signs of fatigue.
The objective of DAC is to detect slowly dete- riorating driving behavior and is primarilyintended to be used on major roads. The func-tion is not intended for use in city traffic. DAC is activated when the vehicle's speed exceeds 65 km/h (40 mph) and remainsactive as 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 lines and compares the direction of the roadwith the driver's movements of the steeringwheel.
The vehicle is moving erratically in the lane.
If driving behavior becomes considerably erratic, thedriver will be alerted by thissymbol in the instrumentpanel, an audible signal and the message
Time for a
break.
If the vehicle is equipped with Sensus Navigation * and the Rest Stop Guidancefunction is activated, suggestions will also be provided for suitable places to take a break. The warning will be repeated after a short time if driving behavior does not improve.
WARNING
Driver Alert Control must not be used to extend a period of driving. The drivershould plan in breaks at regular intervalsand make sure they are well rested.
WARNING
An alarm from Driver Alert Control should be taken very seriously since a sleepy driveris often not aware of their own condition. If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as pos- sible and rest.
Studies have shown that it is just as dan- gerous to drive while tired as it is to driveunder the influence of alcohol or otherstimulants.
