Road sign information - RSI*
General information on RSI

Examples of readable speed-related
The Road sign information function (RSI –
Road Sign Information) helps the driver to
remember which road signs the car has
passed through information on - among other
things - the current speed, the start/end of a
motorway or road, and when overtaking is
prohibited.
If both a sign for motorway/road for motor-
ised traffic and a sign showing the maximum
permitted speed are passed, RSI decides to
show the sign symbol for maximum permitted
speed.
Road signs shown in the combined instrument panel are market-dependent - the illustrations in the manual only show a few examples.

Recorded speed information
When RSI has recorded a road sign with an
imposed speed, the combined instrument
panel displays the sign as a symbol.
End of restriction or motorway
A corresponding road sign is shown in the
combined instrument panel for
approx. 10 seconds in situations where RSI
detects a sign that involves the end of a
speed limit - or other speed-related informa-
tion, e.g. end of a motorway.
Examples of such signs are:
