What does an exclamation mark inside a triangle mean?

[Rocha]

A triangle with an exclamation mark inside 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, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: 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 indicates an automatic transmission fault warning light, signaling a transmission malfunction or transmission fluid 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, indicating either a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire pressure anomaly: A bracket with a horizontal line and an exclamation mark in the middle represents a tire pressure monitoring warning light, which illuminates when the 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 a lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
