How to reset the warning light after tire repair?

Turn on the instrument power, press and hold the reset button until the low tire pressure warning light turns off. Press and hold the reset button again until the low tire pressure warning light flashes three times, then turn off the engine to complete the reset operation.
After my last tire repair, I was also puzzled when the warning light came on. Later, I found out that the Tire Pressure Monitoring System (TPMS) needed to be reset because the tire pressure changes during the repair triggered the alarm. First, I checked the tire pressure of all tires to ensure they were inflated to the correct value (usually the standard value is indicated on the door frame or in the manual). Then, I drove around for about 15 minutes to let the system automatically recalibrate itself, and the light went off. If this method doesn't work, you can look for the car settings menu and manually reset the TPMS using the steering wheel buttons or the central control screen. That's how I solved the problem with my car, saving a trip to the repair shop. However, a reminder: if the light stays on, don't ignore it—it could mean the sensor was loosened or damaged during the tire repair, and you should get it checked by a professional shop. Safety comes first. If the light comes on while driving on the highway, pull over safely and check immediately.
After getting my tire repaired, the warning light was still on, which made me quite nervous. After checking some information, I realized this is a common issue caused by the TPMS system not updating the data promptly. The first step is to confirm that the tire pressure in each tire is correct (it's common to have underinflation or overinflation after a repair). You can use a tire pressure gauge to check it yourself or go to an inflation station to get it done. The second step is to drive a few kilometers at a moderate speed, such as above 60 km/h, and the system will re-detect and turn off the light within minutes. If my car has a manual setting, I can find the TPMS reset option on the dashboard and press it. The third step is if the light still doesn’t turn off, I should suspect a sensor issue or circuit malfunction and immediately contact the tire repair shop or 4S store for troubleshooting. Don’t delay too long to avoid missing a real danger.
