What does a red triangle with an exclamation mark indicate?

[OJames]

A triangle with an exclamation mark indicates a malfunction in the vehicle's regular performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. 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. Besides the triangle with an exclamation mark, there are four other forms of exclamation marks: 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 light 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 malfunction in the transmission or transmission fluid level below the normal range. The 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 brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire pressure abnormality: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow light 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.
