Examples of signs that can be detected2.

If the vehicle passes a speed limit sign, it will be displayed in the instrument panel.

There are also subfunctions for Road Sign Information (RSI1) that can alert the driver if the speed limit has been exceeded or if there are speed cameras nearby.


In certain markets, the Road Sign Information* function is only available in combination with Sensus Navigation*.


  • The function is supplementary driver support intended to facilitate driving and help 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 Owner's Manual about this function to learn of its limitations, which the driver must be aware of before using the function.
  • Driver support functions are not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle 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.
