How to reset the tire pressure warning after changing tires?

After changing tires, the tire pressure warning needs to be reset by performing a tire pressure reset operation. This is a procedure to recalibrate the tire pressure monitoring system after addressing any tire pressure issues. The steps for tire pressure reset are as follows: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the completion of the tire pressure reset. There are generally three reasons for abnormal tire pressure warnings: Abnormal tire pressure: The system typically triggers a warning when the pressure is below 1.8 bar or above 3.0 bar. In such cases, the tires need to be checked and the pressure adjusted accordingly. Tire pressure monitoring not reset: If the tire pressure monitoring system is not reset after inflating the tires, it will continue to display the old data, causing the tire pressure warning light to stay on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire valve. If the sensor is damaged during driving, it can also trigger the tire pressure warning light. In case of sensor damage, the only solution is to replace it with a new one.
I just experienced the issue of the tire pressure warning light staying on after getting new tires. This happens because the TPMS system might still remember the old tire pressure and hasn't updated. First, check if the new tires' pressure is within the correct range, usually the standard value written on the door frame label or manual, like 35psi or 2.3bar. If the pressure is low, go to a gas station or use a tire pressure gauge to inflate them yourself. Then, open the central control settings menu, look for the 'Tire Settings' or 'TPMS Reset' option, and follow the instructions. For models without a menu, start the car but don't move it, then press and hold the reset button on the steering wheel until the light goes off. Drive for a few minutes to let the system learn the new tire pressure. If the warning light remains on, it might be due to a slow leak or a faulty sensor. It's recommended to visit a repair shop promptly—don't delay, as safe driving is crucial.
