Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display:
ATTENTION ASSIST

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.
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 navigation
to this service station will then begin. This func-
tion can be activated and deactivated in
COMAND Online (see the separate operating
instructions).
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
applicable traffic regulation continues to be
shown in the assistance graphic display
(
Y
page 243).
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 avail-
able 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.
