Refer to your vehicle's manual for specific instructions on how to perform this reset. If the warning light persists, it may indicate a malfunctioning tire pressure sensor, which would require professional inspection. Should you find yourself unable to resolve the issue through these steps, it is advisable to consult a certified mechanic or dealership, as they possess the necessary tools and expertise to accurately diagnose and address any underlying TPMS problems.
