Runflat indicator: Operation
The Run Flat Indicator (RPA) is initialized using the following control elements:
- RPA button
- On-board computer button on turn-signal/main-beam switch
- With iDrive in the Central Information Display (CID) with the controller
Set the tires to the correct pressure before performing initialization. During initialization, the set tire pressure is taken as the initial value for the current set of wheels.
Correct the tire pressures when the tires are cold to prevent the data recorded from being affected by temperature.
