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: increased system sensitivity: the
R
driver is warned earlier and the attention level
detected by the system 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 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 driver
display:
