How to Reset the Tire Pressure Monitoring Light?
2 Answers
The method to reset the tire pressure monitoring light is: 1. Depress the brake pedal and press the one-touch start button until the vehicle's power is fully activated; 2. Inflate all four tires to the standard pressure; 3. Press and hold the tire pressure warning light reset button. The principles of tire pressure monitoring are: 1. Direct tire pressure monitoring systems use pressure sensors installed inside the tires to measure air pressure, transmitting data wirelessly from the tire to a central receiver module for display; 2. Indirect systems detect pressure drops by monitoring rotational speed differences between tires, as underinflated tires exhibit smaller rolling radii under vehicle weight.
A few days ago, my tire pressure warning light came on and really worried me. Later, when I asked at the repair shop, I found out the solution was actually quite simple. First, you need to inflate all four tires to the standard value, which is the number posted on the door frame—I usually use the air pump at gas stations. Then, find the menu button on the left side of the steering wheel, locate the tire option in the dashboard display, and hold the reset button for three seconds to reset it. Methods vary by car model; Japanese cars generally follow this procedure, while some German cars require driving a few kilometers for automatic calibration. If the light stays on, you should check for slow leaks or a faulty sensor—sometimes insufficient pressure in the spare tire can also trigger the warning. The mechanic said never to simply pull the fuse to clear the warning light, as it could be dangerous if there’s a real tire issue.
