To reset the tire pressure monitoring system (TPMS) on your Lexus GS350, press and hold the TPMS reset button until the tire pressure light flashes three times, then release it. TPMS is designed to alert you when your tire pressure is low or if a tire is going flat, helping you maintain proper tire pressure for improved safety on the road. Proper tire pressure can enhance your vehicle's handling, reduce tire wear, shorten braking distance, and improve fuel economy. If the light stays on steadily, it indicates that you should have your tire pressure checked. To address TPMS repair needs, it is recommended to use a service kit whenever a tire is repaired or replaced. This kit includes a new TPMS service (repair) Kit with a grommet nut, grommet, valve cap, and valve core.
To recalibrate the tire pressure sensor on the Lexus GS 350, just press and hold the reset button until the TPMS light on the dashboard blinks slowly three times.
