ATTENTION ASSIST
▌Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on motorways and trunk
roads. If indicators of fatigue or increasing lapses
in concentration on the part of the driver are
detected, the system 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-res-
ted and attentive driver. On long journeys, take
regular breaks in good time that allow for ade-
quate recuperation.
You can choose between two settings:
Standard: normal system sensitivity.
R
Sensitive: higher system sensitivity. The driver
R
is warned earlier and the attention level detec-

ted by ATTENTION ASSIST is adapted accord-
ingly.
If drowsiness or increasing lapses in concentra-
tion are detected, the ATTENTION ASSIST: Take
a break! warning appears in the driver's display.
You can acknowledge the message and take a
break where 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.
The following information is displayed in the driv-
