How to Reset the Lexus Tire Pressure Light?
3 Answers
Lexus tire pressure light reset method: 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 reset is successful. Below is an introduction related to tire pressure: 1. Tire pressure refers to the internal pressure of a car's tires. The standard tire pressure for the vehicle model should be indicated on the door. It is most accurate to check the tire pressure after the car has been parked for more than three hours. 2. The value of tire pressure is related to temperature and seasonal changes, increasing or decreasing according to temperature variations. 3. Low tire pressure can cause tire deformation, leading to cracks, accelerating rubber aging, and increasing tire wear. High tire pressure reduces the elasticity of the tire body, making it more prone to blowouts while driving.
I also encountered the tire pressure warning light issue when driving a Lexus NX last time. First, get out of the car and use a tire pressure gauge to check the actual pressure of all four tires to see if there's any obvious air leakage. If any tire pressure is low, promptly inflate it to the standard value—the label on the door frame shows the standard tire pressure parameters. Then, start the vehicle and locate the vehicle settings menu using the buttons on the right side of the steering wheel, select the TPMS system calibration option. At this point, park the car on a flat surface and keep the engine running for about three minutes to allow the system to automatically calibrate. The tire pressure warning light on the dashboard will turn off once successful. If the light remains on, you may need to repeat the process a few times. Occasionally, the tire pressure sensors can be blocked by snow or mud, affecting the signal—cleaning the sensor area near the wheel hub can also resolve the issue. If all else fails, visit a 4S dealership for a deep reset using specialized equipment.
In the fifth year of driving a Lexus, I finally figured out how to reset the tire pressure light. The method is actually simple: after ensuring all tire pressures are normal, start the car and operate directly through the center console screen for quicker results. From the main menu, enter the vehicle settings section, find the tire pressure warning system submenu, and select the reset button. Newer models will prompt automatic calibration while driving, while older models require waiting in place for the progress bar to complete. The key is to operate when the tires are cold, meaning the car has been parked for at least two hours before checking the pressure. The reset will only take effect after the first drive exceeding 40 mph, so don't rush to see the results. I used to forget the standard tire pressure values, but later I wrote the recommended numbers in a memo for easy reference. If you encounter false alarms on rainy days, don't rush to reset the light—sometimes driving on dry roads will automatically restore normal conditions.
