How to Reset the Lexus Tire Pressure Light?
2 Answers
To reset the Lexus tire pressure light: Below the steering wheel and above the brake pedal, there is a small round button. Press and hold it until the tire pressure monitoring yellow light on the dashboard flashes three times, then release. This indicates that the tire pressure monitoring system has been successfully reset. Below is some related information about tire pressure: 1. Tire pressure refers to the internal pressure of a car's tires. There should be a standard tire pressure label for the vehicle model on the inside of the car door. The most accurate time to check tire pressure is after the car has been parked for more than three hours. 2. Tire pressure values are influenced by temperature and seasonal changes, increasing or decreasing with temperature variations. 3. Low tire pressure can cause tire deformation, leading to cracks, accelerated rubber aging, and increased tire wear. High tire pressure reduces the elasticity of the tire body, making it more prone to blowouts while driving.
The tire pressure monitoring light coming on is indeed annoying, and I've seen it quite a few times over my years of driving. For Lexus vehicles, the first step is to check if all tire pressures are normal by referring to the recommended values on the door pillar sticker - typically around 32-35 PSI for both front and rear tires. If the tire pressure is fine but the light remains on, try resetting the system: Without pressing the brake pedal, press the start button twice to enter power mode (dashboard lights on but engine not running), locate the TPMS button near the steering wheel or center console (exact position in the manual), and hold it for several seconds until the light blinks or turns off. Then drive normally for 10-20 minutes for automatic recalibration. If the light persists, the tire pressure sensor battery might be dead or there could be wiring issues, requiring professional diagnosis at a dealership. Never ignore this warning as abnormal tire pressure increases blowout risks and compromises safety. Regular pressure checks during maintenance, especially during seasonal temperature fluctuations, can prevent this issue.
