Where is the tire pressure calibration located on a Mercedes?

Adjust the tire pressure via the buttons on the steering wheel, then select the tire pressure reset option. Mercedes tire pressure reset: Tire pressure reset is an operation performed on the tire pressure monitoring system after addressing a tire pressure fault, to reset the system. Tire pressure reset method: First, turn on the ignition, press and hold the tire pressure monitoring reset button until you hear a "ding" sound, then release. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally the dashboard warning light will turn off, indicating the tire pressure reset is complete. Mercedes tire pressure monitoring light on: The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no stamp on top, four small spikes at the bottom, and an exclamation mark inside. The tire pressure monitoring light indicates abnormal tire pressure. Abnormal tire pressure is generally caused by one of the following three reasons: Abnormal tire pressure: Typically, an alert is triggered if the pressure is below 1.8 bar or above 3.0 bar. In this case, inspect the tires and adjust the pressure. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed promptly, the tire pressure monitoring system retains the old data, causing the tire pressure monitoring light to stay on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light may illuminate. In case of sensor damage, the only solution is to replace it with a new one.
The location for calibrating tire pressure on my Mercedes is quite familiar to me. Having driven my car for several years, I always operate it myself using the steering wheel buttons. After starting the car, I use the scroll key on the left side to enter the dashboard menu, find the vehicle settings option, and then select the tire section. There will be a prompt to reset or calibrate the system—just confirm it. The location is right in the menu; no need to look for a physical button—it’s simple and convenient. Before calibration, make sure the tires are fully inflated. I do this in the parking lot to avoid misjudgment. Last time, the warning light came on due to temperature changes, but after calibration, everything was fine. Developing this habit is important—it prevents false alarms from distracting you while driving and extends tire life. I recommend checking and resetting it once before seasonal changes or long trips—it’s safe and hassle-free.
