What does the yellow exclamation mark symbol in a car mean?

[ManuelLee]

There are four situations when a yellow exclamation mark appears on the car dashboard: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. The following is a detailed analysis of these four situations: General faults: 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. Mainly includes parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic transmission faults: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Abnormal tire pressure: A horizontal line under a bracket with an exclamation mark in the middle. This represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will come on. It is necessary to check the car's tire pressure and restore it to the normal range. Lighting faults: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that there is a fault in the car lights. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lights to see where the problem is. There is also a red exclamation mark with a circle and bracket around it. This represents a warning of the braking system, mainly including braking system faults and low brake fluid levels. It is necessary to immediately inspect and repair the braking system to avoid accidents.
