What Does the Yellow Exclamation Mark on the Steering Wheel Mean?

[Blake]

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system fault. Below is a detailed analysis of these four situations: General Malfunction: An exclamation mark inside a triangle indicates a malfunction in the car's general performance, components, or functions when this symbol lights up. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission issue or that the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark in the middle of a horizontal line below a bracket represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of 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. Additionally, a red exclamation mark inside a circle with a bracket indicates a warning related to the braking system, primarily signaling a braking system malfunction or low brake fluid level. Immediate inspection of the braking system is required to prevent accidents.
