What does the exclamation mark inside a triangle on the dashboard mean?

The exclamation mark inside a triangle on the dashboard refers to a general warning light, which typically indicates issues with the braking system or abnormal tire pressure. There are several reasons why this warning light might illuminate, including overheating of the dry dual-clutch transmission clutch, intervention or malfunction of the fuel cutoff system, parking sensor failure, external light failure, engine oil pressure sensor malfunction, or traction control system warning/failure. The vehicle's onboard computer has a self-diagnostic function. When the car is powered on, the indicator lights on the dashboard will illuminate as the system enters self-check mode. After the self-check is completed, these lights should turn off. If they remain lit, it indicates a vehicle malfunction that requires prompt repair.
I also encountered this triangle exclamation mark on the highway last time, and it gave me a scare thinking my car was about to break down. Actually, this is a general warning light, indicating there's a situation that needs attention but isn't severe enough to require immediate stopping. Common issues include: doors not closed properly, trunk not locked securely, or low windshield washer fluid—minor problems like these. However, it could also indicate unstable tire pressure or abnormalities in the braking system. My advice is to pull over first and check if there are any other warning messages on the dashboard, like a tire pressure anomaly symbol, which would mean you should check the tires immediately. If the light keeps flashing along with other warnings, don't hesitate to call a tow truck. If all else fails, flip through the owner's manual—it provides detailed explanations for what each warning light means in your specific car.
This triangle warning light with an exclamation mark is referred to as the master warning light in the owner's manual, acting like a yellow card warning for the vehicle. It doesn't necessarily mean the car is about to break down, but it demands immediate attention. When I encounter it while driving, I usually perform three checks: feel the steering wheel for any vibrations, check the screen for specific pop-up messages (such as 'Check Engine'), and listen for any abnormal engine sounds. Many beginners tend to panic, but in most cases, it's due to abnormal tire pressure or low windshield washer fluid. Last time, my neighbor had this light on simply because the fuel cap wasn't tightened properly. The key is to distinguish whether it's continuously lit or flashing. If it's flashing, it's best to pull over to a safe area immediately. If it's steadily lit, you can drive slowly to a repair shop for inspection.
