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".

Display view showing obstacle zones and sensor sec-tors.
The center display shows an overview of the vehi-cle in relation to objects that have been detected.
The marked sector indicates where the obstacleis located. The closer the vehicle symbol is to amarked sector forward/rearward, the closer thedetected obstacle is to your vehicle.
The side sectors change color as the distancebetween the vehicle and an object decreases.

Audible signals for obstacles in front and to thesides of the vehicle are active when the vehicle ismoving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm(1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in.
At distances within approx. 25 cm (0.8 ft) from anobstacle to the sides of the vehicle, an rapid puls-ing signal will be given and the active sectorfields will change color from ORANGE to RED.
The volume of the Park Assist audible signalscan be adjusted while the signal is being givenusing the >II knob or in the center display's Topview under Settings.
