When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: A triangle with an exclamation mark inside indicates a general performance or component malfunction in the car. Common issues include parking sensor faults, fuel cutoff system intervention or failure, external light faults, or engine oil pressure sensor faults. It is recommended to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Faults: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or low transmission fluid levels. Immediate replacement of transmission fluid is required. Brake System Faults: A circle with an exclamation mark inside parentheses represents a brake system warning, typically indicating a brake system malfunction or low brake fluid levels. Immediate inspection and repair of the brake system are necessary to avoid accidents. Abnormal Tire Pressure: A horizontal line with an exclamation mark 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 Faults: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
