What does a sun exclamation mark on the dashboard mean?

On the dashboard, a sun exclamation mark is the brake pad warning light, indicating a brake pad fault, which serves as a reminder to replace the brake pads. When the front brake pads are nearing their wear limit, this warning will appear. It is recommended to check whether the brake pads need replacement. If the brake pads do not require replacement, adding some brake fluid may suffice. Before traveling, it is essential to inspect the braking system for normal operation, including the wear level of the brake pads. Additionally, ensure that the power steering fluid is sufficient. Special attention should be paid to the dust cover of the brake system's wheel cylinder. If this component is damaged and allows dust to enter, it can cause the piston to malfunction, leading to an increased braking distance when applying the brakes. If water enters this component, it can mix with the brake fluid, resulting in brake failure.
I often encounter minor issues while driving, and the sun icon with an exclamation mark on the dashboard makes me a bit nervous—it's usually a warning for engine overheating. It could be due to insufficient coolant, or problems with the water pump or fan, leading to poor heat dissipation. Last time this light came on during a long-distance trip, I immediately pulled over to a safe spot, popped the hood to check the coolant reservoir, and sure enough, the level was too low. I added some purified water as an emergency fix and drove to the repair shop, where they found a water pump leak. My advice if you encounter a similar situation: turn off the AC, slow down, and find a place to stop. Don’t keep driving, or you risk serious engine damage. Also, remember to regularly check the coolant level, especially before summer heat waves, and get a maintenance check to avoid many headaches.
