When an exclamation mark appears on the car dashboard, there are five possible scenarios: general faults, automatic transmission failure, braking system failure, abnormal tire pressure, or lighting system malfunction. Below is a detailed analysis of these five situations: General Faults: An exclamation mark inside a triangle 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, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Failure: A yellow gear with an exclamation mark is the automatic transmission fault warning light, indicating a problem with the transmission or that the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Braking System Failure: An exclamation mark inside a circle with parentheses represents a braking system warning, typically indicating a fault in the braking system or low brake fluid levels. Immediate inspection of the braking system is required to prevent accidents. Abnormal Tire Pressure: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light. It illuminates when the 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 fault indicator, signaling a malfunction 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, or interior lights to identify the issue.

What Are the Hazards of the Engine Yellow Warning Light Being On?

Hazards of the engine yellow warning light being on: 1. Deterioration of vehicle exhaust emissions, leading to environmental pollution; 2. Increased fuel consumption, wasting petroleum resources; 3. Elevated combustion chamber temperature and accelerated wear, potentially causing premature engine damage; 4. Engine oil burning; 5. Increased engine noise, affecting driving and passenger comfort. Once the engine warning light illuminates, it indicates that the engine control unit (ECU) has detected some level of abnormality in the engine. If the engine still shows a yellow light after troubleshooting, it is due to stored fault codes in the vehicle's ECU. Connecting a diagnostic tool to clear the system's fault codes will resolve the issue.
