ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto‐
nous journeys, e.g. on highways and trunk roads.
If ATTENTION ASSIST detects indicators of fati‐
gue 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:
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‐
on or off.
