Why is the car's warning light constantly on?

[AnastasiaAnn]

Automotive warning lights depend on the specific light in question. If it's the red light in the upper left corner, it's the oil pressure light, indicating insufficient oil. If it's the orange light in the lower corner, it's the engine fault light, indicating an engine issue. If it's the top light on the right side, it's the seatbelt warning light, indicating that passengers are not wearing seatbelts. The bottom light on the right is the battery fault light, requiring a battery check. Additional information: 1. Different warning lights require different approaches; for example, if the oil level is low, you can check it using the dipstick. If the oil level is below the "min" mark on the dipstick, it means the oil is insufficient, and you only need to add oil. However, if the oil level drops rapidly even after short driving periods, it may indicate the use of counterfeit oil, in which case it's advisable to switch to high-quality oil. 2. If a dashboard warning light comes on while driving, it's essential to promptly visit a 4S shop or a service center to diagnose and fix the issue. Some warning lights require immediate cessation of driving, as ignoring them could lead to severe traffic accidents.
