What does the 'eco' on the car screen mean?

When the eco indicator light on the dashboard illuminates, it indicates that the vehicle'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. When the eco indicator light on the dashboard illuminates, it signifies that the vehicle's economy mode is engaged. 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. Non-active eco mode does not have a dedicated button. When the dashboard eco indicator light illuminates, 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 separate switch button. Therefore, during daily driving, we can generally enable eco mode. However, it is unnecessary to activate 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 impair the vehicle's power performance. Additionally, eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, 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 the eco mode will not function in such scenarios.
I've been driving for over a decade. When the ECO indicator lights up on the dashboard, it's actually your car signaling to help save fuel. Seasoned drivers know that activating this mode changes the car's character—throttle response becomes gentler, automatic transmissions shift up more eagerly, and the AC reduces power output. It's particularly effective during highway cruising, but when climbing hills or attempting to overtake, it's advisable to manually deactivate it, otherwise the power might feel sluggish. Some newer models even display real-time fuel consumption bars on the screen, with green indicating fuel-saving status. However, it's worth noting not to be overly optimistic about halving fuel consumption—manufacturers' claims often exaggerate, with actual savings around 10% being more realistic. Ultimately, driving habits are key; aggressive acceleration renders any mode ineffective.
As a car owner who just bought a car half a year ago, I've researched this feature. The ECO mode button is usually located near the steering wheel. Pressing it will display a leaf icon on the screen, indicating that the fuel-saving mode is activated. The system automatically adjusts engine output, such as cutting off fuel supply earlier when decelerating and making the start-stop function more responsive at red lights. It does save fuel during commutes, but at the cost of slower air conditioning cooling, which can be quite uncomfortable in summer. Last week, when picking up my child from school, I encountered a long uphill slope. Even with the accelerator fully pressed, the car couldn't speed up. I quickly switched back to normal mode and easily climbed the slope. I recommend using it in city traffic jams and turning it off on highways or mountain roads for safety.
