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. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for inspection to identify the fault source. Automatic Transmission Faults: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission fault or low transmission fluid level. The transmission fluid should be replaced promptly. Brake System Faults: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically signaling a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are necessary to avoid accidents. Abnormal Tire Pressure: A horizontal line with parentheses and an exclamation mark below indicates the tire pressure monitoring warning light. This light 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 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.
