How to Reset the Porsche Tire Pressure Light?

[AliceFitz]

To reset the Porsche tire pressure light, insert the key and turn it to the power-on position, then press and hold the SET button for a few seconds. Below are the detailed introductions to the tire pressure monitoring system: 1. Working Principle: The tire pressure monitoring system utilizes the ABS sensing function to compare the rotation counts of the tires. Insufficient tire pressure shortens the tire circumference, causing the rotation count to differ from other tires while driving. 2. Tire Pressure Warning: The tire pressure monitoring system alerts based on wheel speed sensor comparisons. Tire pressure can be checked using a pressure gauge. During driving, the system monitors the inflation pressure of the tires. If the inflation pressure in one tire is significantly lower than the others, the system will issue a warning. As the tire pressure decreases, the working radius of the wheel changes, altering its rotation speed. 3. Initialization: To obtain accurate tire fault information, the system requires the tires to have appropriate initial pressure. Initialization must be performed after adjusting tire pressure, replacing tires or wheels, and when towing a car in trailer mode or after towing.
