page 206).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after
your journey has begun. You then hear an
intermittent warning tone twice and the
Attention Assist: Take a Break! Attention Assist: Take a Break!
message appears in the multifunction dis-
play.
X If necessary, take a break.

Press the a or % button to confirm
the message.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The precon-
dition for this is that ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration.
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction
display in the assistance graphic display.
Speed Limit Assist
General notes
Speed Limit Assist shows you detected speed
limits in the multifunction display. Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected, it
is shown in the multifunction display. If Speed
Limit Assist does not detect any traffic signs,
the speed limit from the digital road map is
used and shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windshield.

Important safety notes
Speed Limit Assist is only an aid and does not
always detect traffic signs with information
about the maximum permissible speed. Traf-
fic signs always have priority over the Speed
Limit Assist display.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray
R
there is glare, e.g. from the sun or from
oncoming traffic
R the windshield is dirty, fogged up or cov-
ered, for instance by a sticker, in the vicinity
of the camera
R the traffic signs are covered, for instance by
dirt, snow or trees
R the traffic signs are poorly illuminated
R
there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads
