What does a triangular exclamation mark on a sedan's dashboard mean?

[Lori]

A triangular exclamation mark on a sedan's dashboard is a general fault indicator light, which may indicate a brake system malfunction. When this light comes on, first check if the handbrake is fully released. If the light remains on after releasing the handbrake, inspect whether the brake fluid level is normal or if the brake pads are too thin. Besides brake system malfunctions, the following situations can also trigger this light: 1. Overheating of the dry dual-clutch transmission clutch; 2. Fuel cutoff system intervention or malfunction; 3. External light failure; 4. Engine oil pressure sensor malfunction; 5. Traction control system warning or malfunction. There are various other lights on the car dashboard that reflect the vehicle's condition. Another common indicator is the oil warning light, which typically illuminates when the engine oil level is insufficient to lubricate the engine, and adding oil usually resolves the issue.
