An exclamation mark inside a gear is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricant is below the normal range. It is necessary to replace the transmission oil promptly. The exclamation mark is a common fault warning in cars. In addition to the exclamation mark inside a gear, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark inside a circle with brackets, an exclamation mark with a horizontal line below brackets, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cutoff system intervention or faults, external light faults, and engine oil pressure sensor faults. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Brake System Fault: An exclamation mark inside a circle with brackets. This represents a brake system warning, mainly indicating a fault in the brake system or low brake fluid levels. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below brackets. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating that a car light has malfunctioned. Solution: Visit a 4S shop for inspection and repair as soon as possible. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the issue.
