Road Sign Information (RSI)*
The RSI function gives information on current speed, e.g. that a motorway or road is starting/ending and when overtaking is prohibited.
If both a sign for motorway/road for motorised traffic and a sign showing the maximum permitted speed are passed, RSI decides to show the sign symbol for maximum permitted speed.
RSI does not work in all situations but is designed merely as a supplementary aid.
The driver always bears ultimate responsibility for ensuring that the vehicle is driven safely and that applicable road traffic rules and regulations are followed.
