Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (
Y
page 183).
The system determines the attention level of
the driver depending on the setting selected:
If Standard Standard is selected: the sensitivity with
which the system determines the attention level
is set to normal.
If Sensitive Sensitive is selected: 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 graphic display.
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 ASSIST ATTENTION ASSIST Take a Take 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 that allow for adequate recuperation. If you
do not take a break and ATTENTION ASSIST still
detects increasing lapses in concentration, 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.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND Online. You can select a service sta-
tion and navigation to this service station will
then begin. This function 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 multifunction camera : attached at the
top of the windscreen. The data and general
traffic regulations stored in the navigation sys-
tem 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 if:
R
the vehicle changes roads (e.g. motorway exit
or slip road)
R
a village or town boundary is passed which is
stored in the digital map
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
