When Will the Exclamation Mark Light Up?

[Etta]

There are five scenarios when an exclamation mark appears on the car dashboard: general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these five situations: General Faults: An exclamation mark inside a triangle indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. 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 is the automatic transmission fault warning light, indicating a transmission fault or low transmission lubricant level. Transmission fluid should be replaced promptly. Braking System Fault: An exclamation mark inside a circle with parentheses represents a braking system warning, typically indicating a braking system malfunction or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside parentheses is the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
