Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (
Y
page 250).
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:
Attention

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 happen only
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 COMAND Online.
You can select a service station and you will then
be navigated to this service station. This func-
tion can be activated and deactivated in
COMAND Online.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted and overtaking restrictions to the
driver in the instrument cluster. Driving onto a
section of road in the wrong direction triggers a
warning. Traffic Sign Assist detects traffic signs
with camera system
:
attached behind the top
of the windscreen. The data and general traffic
regulations stored in the navigation system are
also used to determine the current speed limit.
If a traffic sign that is relevant to your vehicle is
passed, the display of the speed limits and over-
taking restrictions is updated.
The display can also be updated without a visible
traffic sign in the following situations:
R
The vehicle changes roads (e.g. motorway
exit or slip road)
R
A village or town boundary that is stored in the
digital map is passed
R
The last traffic sign detected by the camera
has not been repeated
If a sign indicating the end of a restriction (speed
limit or overtaking restriction) is passed, the
sign is displayed for five seconds. The currently
