If the car is equipped with Sensus Navigation, speed information is read from the navigation unit in the following cases:
- On detection of signs that indirectly indicate a speed limit, such as motorway, dual carriageway and city limit signs.
- If a previously detected speed sign is assumed not to apply any longer, but no new sign has been detected.
In certain markets, the Road Sign Information function (RSI) is only available in combination with Sensus Navigation.
If a downloaded third-party app is used for navigation then there is no support for speed-related information.
