What does the red circle exclamation mark on the dashboard mean?

[LeDamian]

Red exclamation mark (specifically a circle with an exclamation mark inside brackets) indicates a warning for the braking system, mainly indicating a braking system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark representing braking system faults, other exclamation marks on a car are yellow, indicating 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 fault in the car's general performance or components and functions. 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 fault or transmission lubricant level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line under brackets 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 car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb exclamation mark. This is the lighting fault indicator, signaling a fault in the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem.
