What does the yellow exclamation mark on the Jetta dashboard mean?
1 Answers
There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general fault, automatic transmission fault, abnormal tire pressure, or lighting fault. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line with an exclamation mark inside parentheses represents the tire pressure monitoring warning light. This light 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 car 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. Additionally, a red exclamation mark inside a circle with parentheses indicates a warning related to the braking system, such as brake system failure or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents.
