How to Reactivate the RUN FLAT Indicator on a Mercedes Class B W245

Model: Mercedes Classe B W245, MK 1 - Years 2005-2011
Part:

The Run Flat system warning light on the Mercedes Class B W245 alerts us when the pressure drops below a certain level. It is part of the Tyre Pressure Monitoring System (TPMS) and in most cases, it remains lit even after repairing or inflating the tyres. Therefore, you need to reactivate the indicator with a simple procedure. Inflate the tyres to the correct pressure, turn on the ignition, and press the "TPM" button located to the left of the steering wheel, below the air vents. It has the icon of a cross-section tyre: hold it down for 2-3 seconds. You will hear a "beep" and see the light flash; release the button and the light should turn off.
