What Does the Exclamation Mark Warning Light on the Dashboard Mean?

[DiKathryn]

When an exclamation mark appears on the car dashboard, it indicates one of five possible issues: general fault, automatic transmission fault, brake system fault, abnormal tire pressure, or lighting fault. Below is a detailed analysis of these five scenarios: General Fault: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor issues. It is recommended to visit a 4S shop for diagnosis and repair to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission warning light, signaling a transmission fault or low transmission fluid level. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are necessary to prevent accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside a parenthesis is the 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 the lighting fault indicator, signaling a malfunction in one of 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 lights to identify the issue.
