and its menu system (p. 104).
To set Driver Alert in standby mode:
•

Driver support systems
and check the box - No check in the box
means: Standby function disengaged.
Driver Alert is activated when speed exceeds
65 km/h and remains active as long as the
speed is over 60 km/h.
If the vehicle is being driven errati-
cally, the driver is notified by an
acoustic signal plus the text mes-
sage (p. 237)
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 go off:
•
Press the left stalk switch OK button.
WARNING
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
Driver Alert
dangerous to drive while tired as it is under
the influence of alcohol.
