How can the run flat indicator on a Mercedes C-Class be reset?

★ Top Answer

The run-flat tire warning feature on your Mercedes C-Class works together with the tire pressure monitoring system. If the car senses that a tire has no air left, it will alert you that the run-flat function is being used with your original tires. To reset this system, you must fully inflate the tires and then reset the tire pressure monitoring system using the steering wheel controls. Start by pressing the downward arrow, navigating to the Tire Pressure option, pressing OK, and then pressing OK again to view the pressures. Once it confirms that the pressures are normal, it will switch off the warnings.
