Road sign information (RSI)* - limitations

The road sign information function (RSI – Road Sign Information) helps the driver to remember which 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. Find out more about this in the section on the 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 some other 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.
