Road Sign Information*

The Road Sign Information function (RSI1) can help the driver to observe speed-related road signs and certain prohibition signs2.

The function is available in certain markets.

PS2-2007-Road Sign Information readable traffic signs
Examples of readable signs3.

RSI can provide information about such things as current speed, when overtaking is prohibited or when the direction of travel is one-way.

If the car passes a speed limit sign, it will be shown in the driver display.

Road sign information (RSI1) also includes subfunctions that can warn the driver if a speed limit has been exceeded or in connection with speed cameras.


In certain markets, the Road Sign Information function is only available in combination with map data. This may require changing the settings for Google Maps4.


  • The function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The driver is advised to read all sections in the Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
  • Driver support functions are not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
