Road sign information (RSI)* - limitations
The road sign information function (RSI – Road Sign Information) helps the driver to remember which speed-related road signs the car has passed. The function has the following limitations.
The RSI function's camera sensor has limitations just like the human eye - read more about camera sensor limitations.
Signs which indirectly provide information on a prevailing speed limit, e.g. name signs for towns/districts, are not recorded by the RSI function.
Here are several examples of what can disrupt the function:
- Faded signs
- Signs positioned on bends
- Rotated or damaged signs
- Concealed or poorly positioned signs
- Signs completely or partly covered with frost, snow and/or dirt.
