When an exclamation mark appears on the car dashboard, there are five possible scenarios: general fault, automatic transmission fault, braking system fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these five situations: General Fault: A triangle with an exclamation mark inside indicates a general performance or component malfunction. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for diagnosis and repair to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission issue or low transmission fluid level. The transmission fluid should be replaced promptly. Braking System Fault: An exclamation mark inside a circle with parentheses represents a braking system warning, typically indicating a braking system malfunction or low brake fluid level. Immediate inspection and repair of the braking system are necessary to avoid accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light, which illuminates when the 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 is the lighting fault indicator, signaling a malfunction in the vehicle's lighting system. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
