There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting system malfunction. Below is a detailed analysis of these five situations: General Malfunction: An exclamation mark inside a triangle indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission fault or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Brake System Failure: An exclamation mark inside a circled parenthesis represents a brake system warning, typically signaling brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside a parenthesis is 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 System Malfunction: A yellow bulb with an exclamation mark is the lighting system malfunction indicator, signaling a fault in one of the car's lights. 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 lighting to identify the issue.
