What does the exclamation mark mean on a car?
2 Answers
There are generally three types of exclamation mark warning lights that may appear on a car's dashboard: 1. A triangle with an exclamation mark in the middle is a general fault indicator light, which may illuminate in cases such as: overheating of the dry dual-clutch transmission clutch, intervention or malfunction of the fuel cutoff system, or failure of external lights; 2. A circle with parentheses and an exclamation mark in the middle is a brake system warning light, which may illuminate when: it lights up for a few seconds after turning on the ignition and turns off after starting the engine; the brake fluid level is too low; or there is a malfunction in the brake system; 3. A horizontal line with parentheses and an exclamation mark in the middle is a tire pressure monitoring warning light, which illuminates when the pressure in one of the vehicle's tires is too low.
When I see that exclamation mark icon on the car, I know the dashboard is alerting me to some issue. The most common one is the tire pressure monitoring system warning, indicating low tire pressure that needs inflation. If it's yellow, it usually relates to tires; if it's red with a circle, it might signal a brake system problem or the parking brake not being fully released. Some cars use the exclamation mark icon for other alerts too, like worn brake pads or ABS malfunctions. I recommend finding a safe spot to pull over immediately and checking the manual to confirm—never ignore this signal, as low tire pressure accelerates wear and can cause blowouts, while brake issues are even more dangerous. It's best to carry a tire pressure gauge and check regularly, maintaining the manufacturer-recommended levels to avoid surprises. If unsure about the problem, head straight to a repair shop—don't risk driving further.
