What does a yellow circle with an exclamation mark mean on a car?

A yellow circle with an exclamation mark on a car is the brake warning light. If the brake warning light appears red, it indicates an abnormality in the braking system: 1. Severe wear of the brake friction pads; 2. Brake fluid level is too low; 3. The parking brake is already engaged; 4. If the red brake warning light is on and the ABS warning light is also illuminated, the ABS cannot function properly when there is a fault in the conventional braking system. The conventional gauges in a car include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. Under the dashboard cover, there are various indicator lights or warning lights.
I was driving on the road one day when suddenly a yellow circle with an exclamation mark lit up on the dashboard, which made me nervous. I quickly pulled over to check the tires and found that the left front tire pressure was significantly low. This is the Tire Pressure Monitoring System (TPMS) alerting you to insufficient tire pressure. If ignored, it can lead to faster tire wear, reduced grip, increased risk of a blowout, and higher fuel consumption. Later, I went to an auto repair shop where they used a professional pressure gauge to measure and refill the tire pressure, and the light went off. This incident reminded me not to be lazy—always take a quick look at the tires before each trip and maintain the pressure at the recommended value. Regular maintenance not only saves fuel costs but also greatly enhances driving safety.
