What does the ECO displayed on the car mean?

[OAngelo]

When the ECO indicator light on the vehicle's dashboard illuminates, it indicates that the car's economy mode has been activated. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The ECO mode is further divided into active ECO driving mode and non-active ECO driving mode. ECO mode is categorized into active and non-active types, with the difference being that the active type has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active ECO mode does not have a dedicated button; when the dashboard ECO indicator light illuminates, it serves only as a reminder function. ECO automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most vehicles use the active ECO driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can enable the ECO mode. Additionally, the ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car will prioritize speed, and the ECO mode will automatically deactivate. When idling in park or neutral (N/P) gear or in manual mode, the ECO mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will not function.
