Display in MFA, What do the symbols mean

Today I had my car (Seat Cupra) in the workshop and got a Seat Arona as a rental vehicle. After starting the engine the MFA showed for a short time down to the right three characters. What are the meanings? Manual I no longer have, since car left again. Ok, could probably load me the manual from Seat and browse around and look for what the symbols mean. Maybe you forgive me the question (without RTFM ) and my curiosity is quieted what the three symbols mean. 🙂
