Road Sign Information*

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

P5-1507-Road Sign Information, readable signs
Examples of readable signs2.

RSI can provide information about such things as current speed, when a motorway or road is starting/ending, 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 on the driver's display and the head-up display*.


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 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 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.
