A triangle with an exclamation mark indicates a malfunction in the car's general performance or components and functions. Main 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 warning in cars. 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 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 situations: Automatic transmission failure: A yellow gear with an exclamation mark is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil needs to be replaced promptly. Brake system failure: A circle with 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. Abnormal tire pressure: 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 car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting failure: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating a malfunction in 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 problem.
