Important safety notes
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits and over-
taking restrictions. Traffic signs always have pri-
ority over the Traffic Sign Assist display.
The system may be either functionally impaired
or temporarily unavailable if:
R
visibility is poor, e.g. due to snow, rain, fog or
spray
R
there is glare, e.g. from the sun being low in
the sky
R
there is dirt, ice or misting on the windscreen
in the vicinity of the camera
R
traffic signs are hard to detect (dirt, ice, snow)
R
the traffic signs are insufficiently lit at night
R
signs are ambiguous (e.g. traffic signs on con-
struction sites or in adjacent lanes)
R
the information in the digital street map of the
navigation system is incorrect or out of date
Activating Traffic Sign Assist
X
Activate the Traffic Sign Assist display using
the on-board computer (
Y
page 245).
If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
are displayed in the instrument cluster for five
seconds respectively. The wrong-way warning
and the traffic sign display for speed limits and
overtaking restrictions remain active in the
Assist graphic even when the display has been
deactivated.

A maximum permitted speed of 80 km/h
(80 mph) and a speed limit of 60 km/h (60 mph)
with an unknown restriction apply.
No entry (wrong-way warning)
If no entry signs are passed, a warning message
is displayed in the instrument cluster should
Traffic Sign Assist detect that you are driving in
the wrong direction. You will then also hear a
warning tone. You should immediately check
your direction of travel in order to avoid danger
to yourself and other road users.
