When the ECO indicator light on the vehicle's dashboard illuminates, it indicates that the car's economy mode has been activated. ECO stands for the car's economical driving mode, which is an English abbreviation derived from 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. When the dashboard ECO indicator light is on, it means the car's economy mode is active. ECO mode can be either active or non-active. The difference lies in the fact that the active mode has a dedicated button, allowing the driver to choose whether to activate 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. Non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light is on, it serves merely as a reminder function. ECO 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 cars use the active ECO driving mode, which means they have a dedicated switch button. Therefore, during daily driving, you can activate the ECO mode. 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 may not only fail to demonstrate the fuel-saving characteristics of ECO but also affect the vehicle's power. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car 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 the ECO mode will not function in such scenarios.
