Limitations of Road Sign Information*

The Road Sign Information Road Sign Information - RSI function may have limitations in certain situations.
Examples of things that can reduce the RSI function are as follows:
  • Faded signs
  • Signs positioned on bends
  • Rotated or damaged signs
  • Signs positioned high above the roadway
  • Fully/partially obscured or poorly positioned signs
  • signs completely or partly covered with frost, snow and/or dirt
  • digital road maps1 are out-of-date, inaccurate or have no speed information2.

 Note

The RSI function can interpret some types of bicycle rack (connected to the electrical socket for trailers) as a connected trailer. In such cases the driver may be shown incorrect speed information.

 Note

The function uses the car's camera unit, which has some general limitations, see the "Limitations for camera unit" section.
