What Do the Indicator Lights on a Car Mean?
1 Answers
Cars are highly intelligent and sophisticated electromechanical products that operate automatically after being started. To monitor the working status of various systems, cars are equipped with various sensors and electronic control units. If a fault or abnormality occurs in a certain part, the corresponding warning light on the dashboard will illuminate to alert the driver. Depending on the brand and model of the car, the dashboard indicator lights may vary. Some common indicator lights are listed below: 1. Oil Pressure Warning Light: A "kettle"-shaped icon on the dashboard indicates the oil pressure warning light, which illuminates when the oil pressure is abnormal. When the vehicle is started, the oil pressure warning light will turn on. If the oil pressure is normal, it will turn off shortly after. If the oil pressure remains abnormal, it will stay lit. 2. Seat Belt Reminder Light: Most modern cars are equipped with this feature. If the seat belt is not fastened, a small red figure with a strap across the chest will appear on the dashboard, resembling a figure holding a sword. The light will turn off once the seat belt is fastened or the vehicle is exited. 3. Coolant Temperature Warning Light: This light usually stays on when the car is first started, especially in winter. It has a blue thermometer-like shape and illuminates when the coolant temperature is too high or too low. Some vehicles display the coolant temperature with a gauge on the dashboard, where the needle rises or falls with the temperature. 4. Maintenance Reminder Light: A wrench symbol on the dashboard indicates that the car is due for maintenance, not that there is a fault. 5. Tire Pressure Warning Light: A yellow symbol resembling an unclosed irregular circle with four small spikes at the bottom and an exclamation mark inside. This symbol indicates abnormal tire pressure, and the tires should be checked promptly.
