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‐
ted accordingly.
If drowsiness or increasing lapses in concentra‐
tion are detected, the ATTENTION ASSIST: Take
a Break! warning appears in the Instrument Dis‐
play. 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.
You can have the following status information for
ATTENTION ASSIST displayed in the assistance
menu of the on-board computer:

attention level and cannot issue a warning, the
System Suspended message appears.

the multimedia system offers to search for a rest
area. You can select a rest area and start naviga‐
tion to this rest area. This function can be activa‐
ted and deactivated in the multimedia system.
