What are the warning lights on a car?
3 Answers
Introduction to the warning lights on a car is as follows: 1. Common indicator lights: Green indicator light: Function indicator light, serves as a reminder. Yellow indicator light: Fault warning light and function indicator light, serves as a warning. Red indicator light: Fault warning light, indicates a serious warning (only for vehicles with multi-function instrument panels). The exclamation mark indicator light usually lights up simultaneously with other fault indicator lights. 2. Tire pressure monitoring light: The tire pressure monitoring light is the most common and will light up when the tire pressure is too high or too low. For example, if the tire pressure monitoring light suddenly lights up after about 10 minutes of normal driving, it is best to pull over and check all four tires. 3. Water temperature warning light: There are many reasons for the water temperature warning light to come on, such as insufficient coolant, thermostat issues, or the radiator fan not working. It is recommended to pull over. Continuing to drive may cause engine cylinder damage. You can call the service station for guidance or wait for towing assistance. (If coolant is lacking, you can temporarily add tap water, but this situation is rare).
I've driven for many years, and the common warning lights mainly include the engine malfunction light, oil pressure warning light, brake system warning light, airbag warning light, and battery charging warning light. Don't underestimate these. Every time I start the car, I make it a habit to glance at the dashboard: if the engine light comes on, it's usually an emission or sensor issue; if the oil light flashes red, you must stop immediately to check the oil level, or the engine could be ruined; if the brake light stays on, don't drive—safety first; the airbag light indicates a system fault, meaning it won't protect you in an accident; if the battery light stays on, the alternator might be broken. Additionally, if the ABS (anti-lock braking system) warning light comes on, the brakes might skid; the tire pressure monitoring light shows low tire pressure; and the coolant temperature warning light indicates overheating, which can cause engine seizure. These lights are reminders for experienced drivers—never ignore them when they light up, and get to a repair shop right away. Developing a habit of regular checks can help prevent many car troubles.
After driving for a long time, you get used to seeing various warning lights. The engine light is the most common; it might indicate a minor issue, but it could also mean severe carbon buildup. If the oil pressure light comes on, you must stop and turn off the engine immediately to protect it. If the brake light stays on, it might be due to worn brake pads or a leak in the system. The airbag light signals a failure in the airbag system, posing a risk in case of an accident. A constantly lit battery light means the battery isn't charging, and you might break down midway. When the ABS light flashes, braking performance deteriorates. The tire pressure light shows which tire is leaking. There's also the coolant temperature light, which comes on when the engine overheats. Don't just rely on color differences—red lights require immediate action, while yellow lights allow for a slower response. Pay attention to dashboard changes regularly and learn some basic inspection skills to save on repair costs. After all, vehicle safety is a matter of life and death for everyone.
