When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Faults: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. This could include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. 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 that the transmission has a fault or the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light. This light will illuminate when the car's 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 that a car light has malfunctioned. Solution: Visit a 4S shop as soon as possible for inspection and repair, 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 a bracket, which represents a warning for the braking system. This mainly includes braking system failure and low brake fluid level. The braking system should be inspected immediately to avoid accidents.
