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 248).
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
multifunction display.
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.
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 wind-
screen 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
construction 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the navigation system is incorrect or out of
date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 248).
If you have activated the Traffic Sign Assist
display in the on-board computer, the traffic
regulations (speed limits and overtaking
restrictions) are displayed in the instrument
cluster for five seconds respectively. The
wrong-way warning and the traffic sign dis-
play for speed limits and overtaking restric-
tions remain active in the Assist graphic even
when the display has been deactivated.
Instrument cluster display

The following illustrations are examples of
vehicles with colour multifunction display.
The illustrations of vehicles with black and
white multifunction display differ from
them.
i The unit for the speed limit (km/h or mph)
depends on the country in which you are
driving. It is generally neither shown on the
traffic sign nor on the instrument cluster
but must be taken into account when
observing the maximum permitted speed.
