Drowsiness monitor
Introduction
Fig.8 On the instrument panel display:
Drowsiness monitor symbol.
The drowsiness monitor informs the driver
whether his or her driving behaviour is indi-
cative of fatigue.
The drowsiness monitor determines the driv-
er's driving behaviour and uses this information
to assess driver fatigue. If the system detects
that the driver is tired, it indicates this visually
on the instrument cluster display by means of
a control or warning lamp in combination with
a supplementary text message. It also issues
an audible warning
›››page28. The text
message on the instrument cluster screen is
displayed for 4 to 6 seconds.
Conditions of operation
Driving behaviour is assessed only at speeds
above 65 km/h and thereafter only at speeds
above 60 km/h.
WARNING
The drowsiness monitor is no substitute for
the driver's attention and only works within
the limits of the system. Therefore, the
drowsiness monitor may not detect that the
driver is tired in all situations and may not
give a warning or may give a delayed or unin-
tended warning. There is a risk of accidents
and serious or even fatal injuries.
●
Always pay proper attention and do not rely
solely on the system. The driver is responsi-
ble for his or her tness to drive at all times.
●
Note the limits of the system

●
Never drive a vehicle when you are tired.
●
During long journeys, take regular and suf-
cient breaks.
●
Follow the information on the instrument
cluster screen and respond as prompted.
