What does the white exclamation mark mean?

Dry dual-clutch transmission clutch overheating. Below is relevant information about the clutch: 1. Clutch: The clutch is located in the flywheel housing between the engine and the transmission, secured to the rear plane of the flywheel with screws. The output shaft of the clutch serves as the input shaft of the transmission. During driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power from the engine to the transmission. 2. Principle of releasing the clutch: The principle of releasing the clutch is: "slow at first, then fast, and coordinated in three steps." When initially pressing down, do it quickly and fully depress it in one motion. When lifting up, do it quickly during the free travel phase, slow down as it approaches contact, pause slightly at the semi-engagement point, and then release. The key to this process is accurately identifying the semi-engagement point. To control the vehicle speed effectively, use the semi-engagement point as the dividing line—lift quickly above it and lower slowly below it, adjusting downward to select a speed that suits you.
When I saw that white exclamation mark on the dashboard, I immediately thought it might be related to the tire pressure monitoring system, indicating that one of the tires has low pressure or an issue. Having driven for decades, I know this is a common occurrence, especially during long trips or when weather changes cause significant tire pressure fluctuations. My advice is to pull over immediately and check the pressure of each tire using a simple pressure gauge. If it’s noticeably low, inflate it to the recommended value listed on the door-side label. Sometimes, the warning light can be triggered by a damp sensor or uneven tire wear, but don’t take it lightly—low tire pressure increases braking distance, affects handling, and can even lead to a blowout. It’s great that new cars come with this feature; it’s a good reminder to develop a habit of regular tire checks to prevent problems. If you’re unsure, just spend a little money at a repair shop to get it checked—safety should always come first.
Last month I also encountered that white exclamation mark, which really gave me a scare. Turned out it was the car's brake system or tire pressure warning indicator. As an average car owner, I immediately pulled over to a safe spot and checked the manual to confirm the meaning of the light—usually indicating low tire pressure or minor brake issues. I'm accustomed to using a mobile app connected to an OBD tool to read data, and found the right front tire pressure was slightly low, so I topped it up. While I enjoy tinkering with minor repairs myself, complex systems are better left to professional shops. I recommend beginners download a vehicle management app to monitor things regularly—when this warning light comes on, don't force driving on highways as it increases risks of losing control or tire blowouts. After topping up air, the light went off and I felt relieved, but make sure to perform regular self-checks to prevent similar situations.
