What does a triangle with an exclamation mark displayed on the car mean?

The reasons for the decrease in coolant are: 1. Leakage in the engine cooling system; 2. Thermal expansion and contraction; 3. Air retention in certain areas of the cooling system, which causes coolant levels to drop after some time of circulation when the air is expelled. When the water temperature is too high, a triangle with an exclamation mark displayed on the car indicates a vehicle malfunction. This light is also known as the general fault indicator. Other warning lights with exclamation marks in the car include: 1. A red circle with an exclamation mark inside parentheses indicates the brake system warning light, which illuminates when the handbrake is engaged; 2. A yellow horizontal line with an exclamation mark below parentheses indicates the tire pressure monitoring warning light, which only lights up when the pressure in the four tires is unbalanced or too low; 3. An exclamation mark inside a yellow bulb indicates the lighting system fault indicator, which lights up when a bulb malfunctions; 4. An exclamation mark next to a red steering wheel indicates the power steering system fault indicator, which lights up when there is a malfunction or failure in the power steering system, such as a locked steering wheel. Driving issues may occur, and inspection and maintenance are required. Coolant, also known as antifreeze coolant, has antifreeze properties that prevent the coolant from freezing in cold weather, which could otherwise crack the radiator or damage the engine block. Antifreeze is not only for winter use but should be used year-round. As part of regular vehicle maintenance, the engine antifreeze should be replaced every year.
When I suddenly see that triangle warning light with an exclamation mark on the dashboard while driving, my heart always skips a beat because it's usually a general warning indicating there's a minor issue with the car that needs attention. Based on my experience, it could mean there's a problem with the braking system, such as insufficient brake fluid or a faulty brake light; it might also indicate a lighting malfunction, like turn signals or reverse lights not working; or it could signal abnormal tire pressure, with the TPMS reminding you to check; it might even suggest electronic system or sensor issues. If the light comes on, I first pull over to a safe spot, then consult the owner's manual for specific confirmation or simply check if the exterior lights are functioning normally. Never rush to drive far with it on, as it concerns safety - it's best to get to a repair shop as soon as possible to avoid small problems turning into big troubles. In short, this is the car's friendly reminder - don't ignore it.
