What does the red exclamation mark in a car mean?

[OGeorge]

Red exclamation mark (specifically in the form of an exclamation mark inside a circle with parentheses), this represents 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 in 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 general performance or component and function fault in the car. Main issues include parking sensor faults, fuel cutoff system intervention or malfunction, external light faults, engine oil pressure sensor faults, 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 oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below parentheses. 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 light, indicating a fault in one of the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. You can also check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the problem.
