What does it mean when the Mercedes-Benz run-flat indicator stops working?
1 Answers
When the Mercedes-Benz run-flat indicator stops working, it is a tire pressure check reminder, indicating that the pressure of at least one tire deviates from the pressure at the last reset, requiring a recheck of the tire pressure followed by a reset. The owner needs to first check the tire pressure values of all four tires. If the indicator persists after adjustment, they can navigate to the maintenance menu via the steering wheel and select the tire pressure reset option. Below is relevant information about the monitoring systems: 1. Indirect Tire Pressure Monitoring System (TPMS): This system uses speed sensors on the car's wheels to compare the rotation counts of the four tires. If one tire has lower pressure, its rotation count will differ from the others during driving. The indirect TPMS will then detect the tire anomaly but won't display the specific pressure, only alerting the driver of low tire pressure on the dashboard. 2. Direct Tire Pressure Monitoring System (TPMS): This system installs pressure sensors inside or outside the tires, transmitting signals to a receiver that directly displays the tire pressure values on the vehicle's screen. This allows the driver to see the pressure information for each tire, making it a more common TPMS method in the market. Direct TPMS can be further divided into internal and external types based on the sensor installation location. Although their installation positions differ, both internal and external TPMS operate on the same principle, but their sensors vary. Internal TPMS places the sensor inside the tire, while external TPMS mounts the sensor on the valve stem.
