What does it mean to calibrate tire pressure on the Mercedes-Benz E300L?
1 Answers
The Mercedes-Benz E300L displaying 'Please calibrate tire pressure' indicates an alert from the tire pressure monitoring system. The tire pressure monitoring warning light is a yellow symbol, featuring an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of this light signifies abnormal tire pressure. There are generally three reasons for abnormal tire pressure in a Mercedes-Benz: Abnormal tire pressure: The system typically alerts when the pressure is below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the monitoring system continues to record the previous data, causing the tire pressure warning light to illuminate. 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 inflation valve. If the sensor is damaged due to impact while driving, it can trigger the tire pressure warning light. In case of sensor damage, the only solution is to replace it with a new component.
