A gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. It is necessary to replace the transmission fluid 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: a triangle with an exclamation mark, a circle with an exclamation mark in the middle, a horizontal line with an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, 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: A circle with an exclamation mark in the middle. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: A horizontal line with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the 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 a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-inspection, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem.
