General information on RSI
Examples of readable speed signs
1
.
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 cur-
rent speed, the start/end of a motorway or
road, and when overtaking is prohibited.
If a sign for both a 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.
WARNING
RSI does not work in all situations but is
designed merely as a supplementary aid.
The driver always bears ultimate responsi-
bility for ensuring that the vehicle is driven
safely and that applicable road traffic rules
and regulations are followed.
Operation
Recorded speed information.
When RSI has recorded a road sign with an
imposed speed, the sign is displayed as a sym-
bol on the instrument panel.
Together with the symbol for
the current speed limit, a sign
showing that overtaking is
prohibited may also be dis-
played where appropriate.
Additional signs

.
Sometimes different speed limits are signpos-
ted for the same road - an additional sign then
indicates the circumstances under which the
different speeds apply. The road section may
be particularly susceptible to accidents in rain
and/or fog, for example.
An additional sign relating to rain is displayed
only if the windscreen wipers are in use.

Road signs which are displayed in the instrument panel are dependent on the market - the illustration only shows a few examples.
