ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto‐
nous journeys, e.g. on motorways and trunk
roads. If ATTENTION ASSIST detects indicators
of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration
in time. The system is not a substitute for a well-
rested and attentive driver. On long journeys,
take regular breaks in good time that allow for
adequate recuperation.
You can choose between two settings.
Camera
.
Standard: normal system sensitivity.
R
Sensitive: higher system sensitivity. The
R
driver is warned earlier and the attention
level detected by ATTENTION ASSIST is adap‐
ted accordingly.
If drowsiness or increasing lapses in concentra‐
tion are detected, the
a break! warning appears in the Instrument Dis‐
play. You can acknowledge the message and
take a break if necessary. If you do not take a
break and ATTENTION ASSIST continues to
detect increasing lapses in concentration, you
will be warned again after a minimum of
15 minutes.
You can have the following status information for
