When a yellow exclamation mark appears on the car dashboard, there are 4 possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, or lighting system failure. Below is a detailed analysis of these 4 situations: General Malfunction: An exclamation mark inside a triangle 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 lighting failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission malfunction or that the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket 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 System Failure: A yellow bulb with an exclamation mark is the lighting system failure 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. There is also a red exclamation mark inside a circle with parentheses, which indicates a warning for the braking system, mainly due to braking system failure or low brake fluid level. The braking system should be inspected immediately to avoid accidents.
