What does the eco button in the car mean?

[McCaden]

The eco button in the car is a fuel-saving mode, commonly found in Korean and Japanese cars. When the eco indicator light on the dashboard is on, it indicates that the car's economy mode has been activated. There are two types of eco modes: active and non-active. The active mode has an independent button, allowing the owner to choose whether to turn it on. Once activated, the vehicle will automatically adjust its settings. The non-active mode does not have a dedicated button; when the eco indicator light is on, the car will automatically evaluate the driver's behavior and make corresponding adjustments. The eco mode will be deactivated under the following circumstances: 1. When the vehicle speed exceeds 120 kilometers per hour; 2. When the car is idling or in N or P gear; 3. When the car requires significant power to drive. The principle of eco energy saving: The car's computer evaluates factors that affect fuel consumption, such as transmission gear, engine speed, and transmission oil temperature, and then reasonably controls these gears to reduce unnecessary fuel consumption.
