Driver Drowsiness
Detection (DDD)
The driver drowsiness detection monitors
the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the changes in the
driver's steering behavior. The system
cannot replace the need for vigilance on
the part of the driver. Taking a break is
recommended as soon as feeling tired or
at least every two hours. Do not drive
when feeling tired.
Activation or Deactivation
Depending on version, the system is
automatically active by default every time
the engine is started, even if it was
deactivated during the last ignition cycle.
For further information see ð page 120.
The system can be activated or
deactivated via the cluster by using the
steering wheel controls.

Driver drowsiness detection
Driver drowsiness detection operates
from 65 km/h to 180 km/h.
The system monitors the steering
movements based on the driver's input.
The system is initialized when driving five
minutes at a speed above 70 km/h.
If the steering inputs of the driver
suggest a certain level of drowsiness
or inattention by the driver, the system
triggers the first level of alert.
The driver is notified by and an
audible signal is given. A second level
of warning is issued when the driver is
highly drowsy, then the system triggers
a new alert with , accompanied by
a more pronounced audible signal. In
certain driving conditions such as poor
road surface or strong winds etc., the
system may give alerts independent of
the driver's level of vigilance.
