Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 221).
The system determines the attention level of
the driver depending on the setting selected:
Selection Standard
Standard: the sensitivity with which
the system determines the attention level is set
to normal.
Selection SensitiveSensitive: the sensitivity is set
higher. The attention level detected by ATTEN-
TION ASSIST is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction dis-
play in the Assistance display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated (stand-
ard/sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display: ATTENTION ASSISTATTENTION ASSIST Take aTake a
Break!Break!.
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
X
If necessary, take a break.
X
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 properly. If you do
not take a break and ATTENTION ASSIST con-
tinues to detect increasing lapses in concentra-
tion, you will be warned again after 15 minutes
at the earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
Vehicles with COMAND multimedia system:
if a warning appears in the multifunction display,
a service station search is performed in the mul-
timedia system. You can select a service station
and navigation to this service station will then
begin. This function can be activated and deac-
tivated in the COMAND multimedia system (see
the Digital Operator's Manual).
