Road Sign Information (RSI)*
The road sign information function (RSI –
Road Sign Information) helps the driver to
remember which speed-related road signs the
car has passed.
Examples of readable speed related signs
The RSI function gives information on current
speed, e.g. that a motorway or road is star-
ting/ending and when overtaking is prohibi-
ted.
If both a sign for motorway/road for motor-
ised traffic and a sign showing the maximum
permitted speed are passed, RSI decides to
07
show the sign symbol for maximum permitted
speed.

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.
