Call up the assistance graphic and select
ATTENTION ASSIST (

page 221).
The following information appears:
R
Length of the journey since the last break.
R
The attention level determined by ATTENTION
ASSIST (
Attention Level
), displayed in a
bar display in five levels from high to low
R
If ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the
System Suspended
message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (
Y
page 223).
The system determines the attention level of
the driver depending on the setting selected:
If
Standard
is selected: the sensitivity with
which the system determines the attention level
is set to normal.
If
Sensitive
is 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
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 stopped. The sensitivity selected cor-
responds to the last selection activated (
Stand‐
ard
/
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: Take a
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 to allow yourself to rest properly. If you do
not take a break and ATTENTION ASSIST con-
tinues to detect increasing lapses in concentra-
tion, 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 given in the multifunction display,
the multimedia system offers a service station
search. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated
in the multimedia system.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit.
Traffic Sign Assist is a map-based system, and
for this reason, traffic signs put up temporarily
(e.g. near roadworks) are not detected. There is
also no display for changing traffic signs.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown.
The sign indicating the end of a restriction only
appears with the restriction in the instrument
cluster when:
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 appears in the
instrument cluster either.
