Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (
Y
page 222).
The system determines the attention level of
the driver depending on the setting selected:
Standard selected: the sensitivity with which
the system determines the attention level is set
to normal.
Sensitive selected: the sensitivity is set higher.
The attention level detected by ATTENTION
ASSIST is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the
À
symbol and OFF appear in the multifunc-
tion display in the assistance graphics display
when the engine is running.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been switched off. The sensitivity selected
corresponds to the last selection activated
(standard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display:

Confirm the message by pressing the
a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take
a break, you will be warned again after
15 minutes at the earliest. This will only happen
if ATTENTION ASSIST still detects typical indi-
cators of fatigue or increasing lapses in concen-
tration.
Vehicles with COMAND Online: if a warning is
output in the multifunction display, a service
station search is performed in the multimedia
system. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated
in the multimedia system.
