What should you do when the yellow steering wheel light comes on?
1 Answers
When a yellow exclamation mark appears on the car dashboard, there are 4 possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of each situation: General malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance or components. Possible causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended 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 low transmission fluid level. The transmission fluid should be replaced promptly. Abnormal tire pressure: An exclamation mark below a horizontal line inside parentheses represents the tire pressure monitoring warning light. This light comes on when the tire pressure is too low. Check the tire pressure and adjust 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 represents a brake system warning. Possible causes include brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.
