Here is an introduction to common car warning lights: 1. Engine warning light: When the engine warning light on the car illuminates, it indicates a fault in the car's engine, which is generally very serious; 2. Battery indicator: During driving, the battery is a crucial component. If there is an issue with the battery, it can cause driving problems; 3. Fuel warning light: While driving, it's essential to monitor your car's fuel level. Many new drivers often neglect refueling; 4. Brake disc abnormal warning light: If the brake disc warning light comes on while driving, it indicates severe wear of the car's brake discs or a significant issue with the sensor; 5. Brake system warning light: If the brake system warning light illuminates, it means there is a fault in the car's brake system or insufficient brake fluid.
As a car enthusiast who deals with vehicles all day long, I think there are quite a few common warning lights. The yellow little engine icon of the check engine light is the most annoying—when it lights up, it means there's a problem with the engine system, which could be an emissions issue or a sensor malfunction. The oil pressure light is also crucial, shaped like an oil can. If it lights up, you must stop and check the oil immediately, or the engine could be ruined. The battery indicator is shaped like a small battery—it lights up when there's an issue with the charging system, such as a faulty alternator or poor wiring contact. Then there's the brake system warning light, usually a circle with an exclamation mark, which could mean the handbrake is engaged or the brake fluid is low. If the ABS light is on, it indicates a fault in the anti-lock braking system—it's a small yellow light with the letters ABS. The coolant temperature warning light looks like a thermometer in water—red means the engine is overheating, and you must stop and turn off the engine. The tire pressure monitoring light is a tire icon with an exclamation mark, signaling abnormal tire pressure. If the airbag light is on, it means the airbag system has failed and needs immediate inspection. Some dashboard lights are green or blue, which aren't major issues, like the indicators for parking lights or low beams being on.
Having driven for over a decade, I've basically seen all the warning lights on the dashboard. The engine malfunction indicator light is the most common - when that yellow engine symbol lights up, it's advisable to read the trouble codes as soon as possible. If the red oil pressure warning light comes on, you must immediately turn off the engine and check, as it could be triggered by insufficient oil or oil pump failure. The engine coolant temperature warning light requires special vigilance - pull over immediately when you see it and check the antifreeze level after the engine cools down. That exclamation mark inside a circle brake warning light could mean the parking brake isn't fully released or there might be a brake system malfunction. When the yellow ABS letters light up on the dashboard, normal braking still works but the ABS function is disabled. Don't ignore the airbag warning light either, as it concerns passenger safety. If the tire pressure monitoring system light comes on, check your tire pressure first - you might have a puncture. All these lights briefly illuminate during startup for self-check, which is normal, but if they stay on while driving, be cautious. Regular maintenance can reduce the frequency of warning lights appearing.
