What Does the Tire Pressure Warning Light Look Like?
2 Answers
Tire pressure warning light is a yellow symbol, resembling an irregular circle without a seal on top and four small spikes at the bottom, with an exclamation mark inside. Currently, most vehicle models are equipped with a tire pressure monitoring system that continuously checks whether the tire pressure is normal. When there is an issue with the vehicle's tire pressure, the tire pressure warning light will illuminate. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: It usually triggers an alarm when the pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record 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, it can also cause the tire pressure warning light to illuminate. For sensor damage issues, the only solution is to replace it with a new component.
Having driven for several years, I'm very familiar with the appearance of the tire pressure warning light. It's a conspicuous yellow icon on the dashboard, shaped like half a tire rim outline with an exclamation mark in the middle, similar to international standard safety symbols. When this light illuminates, it indicates potentially low tire pressure or system-detected abnormalities. Like that time during a long-distance drive when it suddenly lit up - I slowed down, pulled over, and found a small nail puncture in the left front tire causing air leakage. Ignoring it leads to accelerated tire wear and potential blowouts, which is quite dangerous. The proper response is simple: safely park, manually check tire pressure, inflate if necessary, or visit a repair shop. Icon details vary slightly across models - compact cars may have smaller icons while SUVs display larger ones, but the warning yellow color remains consistent to remind drivers not to be careless.
