What causes the exclamation mark to appear on the car?

[RichardRose]

There are five situations when an exclamation mark appears on the car dashboard, namely general faults, automatic transmission faults, brake system faults, abnormal tire pressure, and lighting faults. The following is a detailed analysis of these five 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. Main issues include 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 a fault in the transmission or transmission lubricant below the normal range. The transmission oil needs to be replaced promptly. Brake system faults: An exclamation mark inside a circle with parentheses. This represents a brake system warning, mainly indicating a fault in the brake system or low brake fluid level. The brake system needs to be inspected immediately to avoid accidents. Abnormal tire pressure: An exclamation mark in the middle of a line below parentheses. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. 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 a fault in the car lights. Solution: Go to a 4S shop for inspection and handling as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lighting to see where the problem lies.
