What does the circle with an exclamation mark mean on the car display?

Red exclamation mark (specifically a circle with an exclamation mark inside parentheses) indicates a warning for the braking system, mainly signaling a braking system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system are required to avoid accidents. Apart from the red exclamation mark representing braking system issues, other exclamation marks on a car are yellow, indicating general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four scenarios: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. A visit to a 4S shop is necessary to diagnose and address the fault source. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line under parentheses with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
