What is the car tire pressure warning symbol?
2 Answers
The tire pressure monitoring indicator is a yellow symbol, featuring an irregular circle with no seal on top and four small spikes at the bottom, enclosing an exclamation mark inside. The illumination of the tire pressure monitoring indicator signifies abnormal tire pressure. Abnormal tire pressure generally stems from the following three causes: Abnormal tire pressure: The system typically triggers an alert when the pressure falls below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: If the tire pressure is not reset promptly after inflation, the system retains the previously recorded data, causing the tire pressure monitoring indicator 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 directly installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving, such as by impact, it will also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new component.
The tire pressure warning light is a small icon on the car's dashboard, shaped like a tire with an exclamation mark inside, usually yellow and flashing to alert you of an issue. When this light comes on, it indicates that the tire pressure may be too low or too high, which can easily lead to a blowout or affect braking distance. Having driven for over a decade, I've seen many friends ignore it and end up in accidents. I remember once when it suddenly lit up on the highway. I pulled over and used the portable tire pressure gauge to check, finding the front tire pressure was only 1.8 bar, while the normal value is around 2.3. I quickly found a repair shop to refill the air. It's recommended to check the tire pressure monthly, measuring when the tires are cold for accuracy. Don't underestimate this—improper tire pressure increases fuel consumption and wear. Safety always comes first.
