Warning in the multifunction display
If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: Attention Assist: Attention Assist:
Take a break!
Take a break!
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing 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
continues to detect increasing lapses in con- centration, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION 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
station 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 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
overtaking 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 applicable traffic regulation then appears
in the instrument cluster.
The camera also detects traffic signs with a
restriction indicated by an additional sign
(e.g. in wet conditions).
The traffic signs are only displayed with the
restrictions if:
R the regulation must be observed with the
restriction, or
R Traffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the
available sources, no speed limit is displayed
in the instrument cluster either. Driving systems
