P3-746 Symbol Driver Allert Paus

If the vehicle is being driven erratically, the driver is notified by an acoustic signal plus the text message Driver Alert Time for a break - the linked symbol is illuminated in the combined instrument panel at the same time. The warning is repeated after a time if driving ability does not improve.

The warning symbol can be switched off:

  • Press the left-hand stalk switch OK button.


An alarm should be taken very seriously, as a sleepy driver is often not aware of his/her own condition.

In the event of an alarm or a feeling of tiredness; stop the car in a safe manner as soon as possible and rest.

Studies have shown that it is equally as dangerous to drive while tired as it is under the influence of alcohol.
