What does it mean when the tire pressure monitoring indicator light comes on in a Mercedes-Benz?
1 Answers
When a Mercedes-Benz displays the 'check tire pressure' message, it means the tire pressure monitoring system is alerting you. The tire pressure monitoring indicator is a yellow symbol featuring an irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside. The illumination of this indicator 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 this case, 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 system retains 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 inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, such as by hitting a curb, it can trigger the tire pressure warning light. In case of sensor damage, the only solution is to replace it with a new one.
