What is the function of Nissan ECO?

ECO is the economic driving mode of a car, an 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 passive eco driving mode. When the eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and passive types. The difference lies in 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 turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The passive 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 cars employ the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to activate 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 not only fail to demonstrate the fuel-saving characteristics of Eco mode but also impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, and the Eco mode automatically deactivates. During idle parking or in N/P gear and manual mode, the Eco mode may also become ineffective. When a large 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.
I've been driving a Nissan for almost eight years, and the ECO mode has been a great help in my daily driving. It mainly works by adjusting throttle response and air conditioning output to make the car more fuel-efficient. On city roads or in traffic jams, I often turn it on. The car accelerates less aggressively, making the ride smoother without sudden surges, which indeed saves some fuel costs. Over time, my fuel consumption has decreased by about 10%, which feels quite wallet-friendly. The ECO mode also automatically adjusts the transmission shift logic to reduce unnecessary power output, such as being more efficient during steady-speed driving. However, it's worth noting that when climbing hills or trying to overtake, I usually turn off ECO mode because the slower power response might affect safe driving. In short, it's a small but practical feature, and I recommend drivers use it according to road conditions.
