What does the ECO display mean?

[LaCourtney]

The ECO display indicates that the vehicle's economical driving mode is 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. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate 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. 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 vehicles employ the active ECO driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can activate the ECO mode. However, it is unnecessary to enable ECO mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would fail to demonstrate the fuel-saving characteristics of ECO and could also impact performance. 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 may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes delivering sufficient power to drive the vehicle, and the ECO mode will not operate under these conditions either.

The ECO display refers to the fuel-saving mode indicator on the car's dashboard. After years of driving, I've noticed that when it lights up, it informs the driver that the vehicle has entered the most fuel-efficient mode, and the system will automatically adjust certain functions to control fuel consumption. For example, the throttle response becomes less sensitive—stepping on the accelerator won't deliver aggressive power output but ensures smooth acceleration. The transmission also shifts gears earlier to maintain lower RPMs. The air conditioning fan speed slows down to reduce electrical consumption. I often use it in city traffic jams, where fuel consumption can drop from 9L to around 8.5L. However, it's best to turn it off when driving on mountain roads or overtaking, as acceleration becomes sluggish. Long-term use can indeed save money—the monthly fuel savings are enough for a hot pot meal.

Every time I see the little green leaf icon light up on the dashboard, I know the ECO mode is activated. This feature is perfect for commuters like me who squeeze through rush hour traffic every day. The system limits power output, making the car drive exceptionally gently. Pressing the accelerator feels like stepping on cotton, but it doesn't matter since you can't go fast in congested areas anyway. The most noticeable change is the weaker air conditioning cooling—it takes a while to cool down on hot summer days, but fuel consumption drops by about 0.8 liters. I calculated it with a mobile app, and it saves me around thirty bucks a month on gas. I wouldn't recommend using it on highways, though. Last month, I almost failed to overtake a truck with ECO mode on—the power response was too slow, which felt a bit dangerous.

The small green ECO light indicates the car is running in the most fuel-efficient mode. Primarily designed for urban driving conditions, it saves fuel through three methods when activated: throttle response is slowed to avoid sudden acceleration and fuel consumption, the transmission shifts up earlier to maintain an economical engine speed around 1500 RPM, and the air conditioning power is limited to reduce fan speed. Based on my tests, using ECO mode during commutes can save 0.6 liters of fuel per 100 kilometers. However, it may consume more fuel on long-distance trips because engine efficiency is lower at reduced RPMs. It's recommended to use it in congested city traffic and turn it off on highways. The operation is straightforward—just press a button on the steering wheel, making it easy even for beginners to use immediately.
