RPA: Run Flat Indicator

WARNING: This page is about a different variant/trim than selected.

The Run Flat Indicator (RPA) is not a function of the driving dynamics control. The RPA is integrated in the DSC control unit, as for this function the 4 wheel speed signals are required. The system uses the 4 wheel speeds to compare deviations in the tire rolling circumference of the individual wheels. This means that a creeping tire pressure loss is detected. The Run Flat Indicator can be initialized as follows:

On vehicle with Car Communication Computer (CCC): in the Central Information Display (CID) in the menu "Setup"
On vehicles without Car Communication Computer (CCC): in the instrument panel in the on-board computer functions
