only happen if ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration.
If a warning is output in the multifunction dis-
play, COMAND Online provides a service sta-
tion search. 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 vehicleis 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 currently applicable traffic regulation
continues to be shown in the assistance
graphic display (Y page 257).
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. Traffic Sign Assist is not available in all coun-
tries. In this case, display :is shown in the
speedometer.
Important safety notes Traffic Sign Assist is only an aid and is not
always able to correctly display speed limits
and overtaking restrictions. Traffic signs
always have priority over the Traffic Sign
Assist display.230
