How to reset the tire pressure warning on Mercedes-Benz GLC?
2 Answers
Method to reset the tire pressure warning on Mercedes-Benz GLC: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "ding" sound before releasing. 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, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Typically, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring 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 tire pressure, is installed directly inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.
When I first encountered the tire pressure warning on my Mercedes-Benz GLC, I was quite nervous, but fortunately, it wasn't complicated to resolve. As a new car owner, I immediately found a place to pull over when the light came on while driving in the city. I used the built-in pressure gauge to check all four tires, and they were around the standard value of 2.5 bar, which put my mind at ease. Then, without starting the engine, I used the buttons on the right side of the steering wheel to navigate the dashboard menu, selected Vehicle Settings—Tire Pressure Monitoring—Reset System, and followed the prompts to confirm. After resetting, I drove slowly for about five to six minutes to allow the ABS sensors to calibrate, and the warning light went off. The whole process was like a small learning experience—it didn’t take much time but was essential. Low tire pressure can easily lead to blowouts or uneven tire wear, increasing fuel consumption. Developing a habit of checking tire pressure monthly reduces the chances of warnings and ensures safety and peace of mind.
