Let's see in this video how to reset the runflat error on a Mercedes-Benz Class B: this is a warning from the Tire Pressure Monitoring System (TPMS), indicating an issue related to the tires, which is typical for Mercedes-Benz vehicles. The meaning of the error indicates a flat or damaged tire, a malfunction of the TPMS sensor, or tire incompatibility (in fact, they may not be compatible with the Mercedes monitoring system: it's rare but can happen).

To reset the warning light, turn on the ignition, select from the menu button until you reach the mileage, then press the up arrow once, and a message will appear telling us to press the "R" button, which is located on the left side of the speedometer.

Then press the "+" button on the control panel to the right of the steering wheel, and that's it.
