You can choose between two settings:
R
Standard: normal system sensitivity.
R
Sensitive: higher system sensitivity. The
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:
R
The length of the journey since the last
break.
R
The attention level determined by ATTENTION
ASSIST.
If ATTENTION ASSIST is unable to calculate the
attention level and cannot issue a warning, the
System Suspended
message appears.
If a warning is given in the Instrument Display,
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.
If ATTENTION ASSIST is deactivated, the
Û
symbol appears in the assistance graphic in the
Instrument Display when the engine is running.
ATTENTION ASSIST is activated automatically
when the engine is re-started. The last selected
sensitivity level remains stored.
