A gear with an exclamation mark inside 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 indicator in cars. Besides the gear with an exclamation mark, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark in the middle of a circle with brackets, an exclamation mark in the middle of a horizontal line under 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 failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Brake System Fault: An exclamation mark in the middle of a circle with brackets. This represents a warning for the brake system, mainly indicating a brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: An exclamation mark in the middle of a horizontal line under 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, signaling that a car light has failed. Solution: Visit a 4S shop for inspection and repair 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.
