What does the exclamation mark on the dashboard indicate?

The reasons for an exclamation mark appearing on the dashboard: 1. A triangle with an exclamation mark inside indicates a general fault warning light, which may illuminate due to reasons such as overheating of the dry dual-clutch transmission clutch, intervention or malfunction of the fuel cut-off system, engine oil pressure sensor failure, or traction control system warning or malfunction; 2. A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the air pressure in one of the vehicle's tires is too low; 3. A circle with an exclamation mark inside indicates the brake system warning light, which may illuminate due to reasons such as low brake fluid level, illumination during driving, or malfunction of the brake system.
I once encountered a yellow exclamation mark lit up on the dashboard while driving on the highway at night, which really panicked me. I immediately pulled over at a service area to check. Later, the mechanic explained that this symbol usually indicates an important warning: most commonly, it signals brake system issues, such as the handbrake not being fully released or insufficient brake fluid; it could also mean the tire pressure is too low, triggering the tire pressure monitoring system alarm; in rare cases, it might be a false alarm due to stability control system failure or a burnt-out bulb. Now, I always remind myself not to be careless when I see it—slow down and pull over: first, confirm if the handbrake is released, then get out to check if any tires are abnormally flat; if the issue can't be resolved, drive to a professional shop immediately to diagnose the fault code. Regular maintenance can prevent these issues, such as checking brake fluid levels and tire pressure. Safe driving shouldn't rely on luck—a small warning might indicate a bigger problem.
When the dashboard suddenly flashes a warning light while driving, I usually handle it calmly without slamming on the brakes. Among the common causes, the first thing that comes to mind is tire-related issues. Many new cars are equipped with tire pressure sensors, and the light will come on if the pressure drops too much. However, brake problems are also common, possibly due to an improperly positioned handbrake lever or low brake fluid. In such cases, I pull over and try pulling and releasing the handbrake to see if the light goes off. Then, I quickly check the tire pressure values using a mobile app or the car's onboard system, or step out to press the tires and feel their firmness. Sometimes, long-distance driving can cause false alarms due to thermal expansion and contraction of the tires, but it's always better to check for safety. Never ignore this, as it could lead to delayed brake response. Developing the habit of glancing at the dashboard before driving is crucial to spotting issues early and avoiding risks. Remember to maintain your vehicle in good condition, such as regularly changing tires and servicing the brake system.
