On the instrument cluster display: Drowsiness Monitor
symbol.
The Drowsiness Monitor informs the driver if their driving shows signs of fatigue.
The Drowsiness Monitor determines the driver’s driving behaviour while driving and uses this information to evaluate the tiredness of
the driver. If the system detects that the driver is tired, it provides a visual indication of this on the instrument cluster display by means
of a warning or indicator lamp in combination with a supplementary text message and also issues an acoustic warning → Warning
levels of the Drowsiness Monitor. The text message on the instrument cluster display is shown for around 4 to 6 seconds.
Function conditions
The driving behaviour is evaluated for the first time only at a speed of more than around 65 km/h (around 40 mph) and then only at
speeds above around 60 km/h (around 37 mph).
WARNING
The Drowsiness Monitor is not a substitute for the full attention of the driver and operates only within the limits of the system. The
Drowsiness Monitor therefore may not detect that the driver is tired in all situations and may not warn or may warn with a delay or in
an undesired way. There is a risk of accidents and serious or even fatal injuries.
● Always pay due attention and do not rely exclusively on the system. The driver is responsible at all times for their fitness to drive.
● Observe the system limits (→ Drowsiness Monitor).
● Never drive a vehicle when you are tired.
● During long trips, take regular and sufficient breaks.
● Follow the information in the instrument cluster display and respond according to the requests (→ Drowsiness Monitor).
