What is the function of Nissan ECO?

ECO stands for the economic driving mode function of a car. ECO is an English abbreviation formed by 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 indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type 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 Eco indicator light on the dashboard illuminates, 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 employ the active Eco driving mode, meaning they have a dedicated switch button. Thus, during daily driving, you can activate 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 would fail to demonstrate the fuel-saving characteristics of Eco and could negatively impact 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 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.
Nissan's ECO function is primarily an energy-saving mode. When activated, the system automatically adjusts engine output and transmission logic. For example, throttle response becomes smoother, and air conditioning power is reduced, which helps decrease fuel consumption during sudden acceleration. When I drove the Teana, I tested it and found that using ECO in city traffic congestion saved nearly 1 liter of fuel. However, it's worth noting that it's best to turn it off when overtaking on the highway, as there might be a noticeable delay in power response. The ECO button is usually located near the center console, marked with a small leaf icon. Pressing it will display a green ECO indicator on the dashboard. Remember to have the relevant sensors checked by a technician during regular maintenance to prevent carbon buildup from affecting the ECO function's performance.
ECO mode is an intelligent fuel-saving assistant in Nissan vehicles. It controls the engine's fuel injection through the driving computer, keeping the RPM within the economical range, and even makes gear shifts smoother. When driving the Sylphy, I noticed that with ECO mode on, the tachometer rarely exceeds 2000 RPM, making it particularly suitable for city commuting. However, be aware that it may slow down the heating during cold starts, and in stop-and-go traffic, you might feel a slight lack of power. For daily use, pairing 92-octane fuel with ECO mode is the most cost-effective. Also, avoid using a high-pressure water gun directly on the front grille when washing the car, as it houses the intake air temperature sensor.
