What does it mean when the vehicle's eco light is green?

[LaPatrick]

When the dashboard displays "eco," it indicates that the vehicle's economy mode is activated. Eco is an English abbreviation derived from Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further categorized into active eco driving mode and non-active eco driving mode. Eco mode is divided into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the eco mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active eco mode does not have a dedicated button. When the dashboard eco indicator light turns on, it serves merely as a reminder function. The eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most vehicles employ the active eco driving mode, meaning they have a dedicated switch button. Therefore, eco mode can be enabled during daily driving. However, it is unnecessary to enable eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of eco mode but also affect the vehicle's power. Additionally, eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and eco mode will not function in such scenarios.
