What does the exclamation mark inside a triangle displayed on the car represent?

A triangle with an exclamation mark indicates a malfunction in the vehicle'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. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in vehicles. In addition to the triangle with an exclamation mark, there are four other forms of exclamation mark indicators: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark 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. Brake system fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure anomaly: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the vehicle's 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 the vehicle'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 lighting to identify the issue.
I've driven several cars, and when that triangle with an exclamation mark light comes on, it usually indicates a warning or fault in the vehicle system. This is the master warning light, and there could be many possible reasons, such as low tire pressure, a burnt-out bulb, brake system issues, insufficient engine oil, or airbag faults. Every time I encounter this light, I first recall if there were any abnormal sensations while driving, like body vibrations or slower brake response. The best approach is to pull over as soon as possible and check other indicator lights on the dashboard for combined judgment. For example, if the tire pressure light is also on, it's likely that the tire pressure is too low and needs inflating. Ignoring it could worsen the problem and lead to safety hazards. I recommend consulting the owner's manual or going directly to a repair shop to scan for trouble codes to identify the root cause. Regular vehicle maintenance can reduce such warnings. I remember one time my car's light came on, and it turned out to be a faulty trunk lock; I fixed it by replacing a part myself.
