How to reset the tire pressure on a Mercedes-Benz GLC?

Method to reset the tire pressure on a Mercedes-Benz GLC: First, turn on the ignition, then press and hold the tire pressure monitoring reset button. After hearing a "ding" sound, release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system usually triggers an alarm if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are necessary. Failure to reset the tire pressure monitoring: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors the tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, for example, by hitting a curb, it can also cause the tire pressure warning light to illuminate. In case of sensor damage, the only solution is to replace it with a new one.

I've been driving a Mercedes-Benz GLC for three years, and I remember the tire pressure reset procedure very clearly. With the engine off, insert the key and turn it to the second position without starting the engine. Use the buttons on the left side of the steering wheel to navigate to the vehicle menu, then use the left and right buttons to switch to the maintenance section. Scroll up and down to find the tire pressure reset option. After pressing confirm, the dashboard will display a prompt. Wait for the countdown to finish, and the reset will be complete. The key point is that all four tires must be inflated to the standard pressure for the reset to succeed; otherwise, the system will report an error. Last time, after resetting, I added a bit more air to the front tires before a highway trip, and the system responded normally. After resetting, it's best to drive for about 10 minutes to let the system relearn the data, which is especially reassuring on rainy and slippery roads.
