What's the Difference Between Tire Pressure Warning and Tire Pressure Display?

[Mercedes]

Tire pressure display allows you to visually see the tire pressure, while tire pressure warning is just an alarm system that alerts you when the tire pressure is too high or too low. Abnormal tire pressure can occur due to the following reasons: Abnormal tire pressure: Generally, an alarm will sound if 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 in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. In this case, simply reset the tire pressure. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is installed directly inside the tire, connected to the tire inflation valve. If the tire pressure sensor is damaged during driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, only a brand-new replacement part can be used.
