The MP 89 is also equipped with an audio and visual automatic system (ASVA) which automatically detects the positioning of the station platform (whether the platform is on the left, or on the right side of the train). This detection allows the automatic opening of the train doors on the appropriate side of the platform. The system also allows for the operation of automated station announcements. Instead of the conductor having to utilize the intercom to announce station names, the automated system does this automatically. On curved stations, this system is especially vital due to the gap between the train and the curved platform. Automated messages announce the presence of the curves.
