What does a yellow exclamation mark on a car mean?

Car showing a yellow exclamation mark indicates a brake system malfunction, usually caused by the handbrake not being released. In most cases, it will disappear after releasing the handbrake. If it doesn't disappear, you need to go to a 4S shop for inspection and repair. There are generally three types of exclamation mark indicator lights on a car's dashboard: 1. A triangle with an exclamation mark in the middle: This is a general fault indicator light; 2. A circle with parentheses and an exclamation mark in the middle: This is a brake system warning light; 3. A horizontal line with parentheses and an exclamation mark in the middle: This is a tire pressure monitoring warning light, which lights up when the pressure of a certain tire is too low.
That happened not long after I started driving. Once on the highway, a yellow exclamation mark suddenly appeared on the dashboard, which really freaked me out, so I quickly pulled over. Upon checking, I found out it was due to low tire pressure, which triggered the tire pressure monitoring system light. Other common causes include ABS brake system failure or severely worn brake pads. Low tire pressure not only makes the car feel unstable but also causes fuel consumption to skyrocket, and in severe cases, it could lead to a tire blowout and an accident. I tried measuring the tire pressure myself with a gauge and sure enough, one tire was flat. I went to a roadside shop to inflate it, and that solved the problem. Since then, I always check the tire pressure before any long trip. Safety is the top priority. If you see this light, don’t ignore it—stop immediately to check or go to a repair shop to avoid serious consequences.
