Red exclamation mark (specifically a bracket circle with an exclamation mark in the middle) represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the brake system is required to avoid accidents. Apart from the red exclamation mark indicating brake system failure, all other exclamation marks on a car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a general performance or component/function malfunction in the car. Common issues include parking sensor failure, fuel cutoff 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. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A bracket with a horizontal line below and an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which illuminates 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 exclamation mark. This is the lighting fault indicator light, signaling a malfunction in the car's lights. 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.
