What does ECO mean in Nissan Sylphy?

ECO refers to the car's economical driving mode function. 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 is illuminated, it indicates that the vehicle's economical 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. The non-active eco mode does not have a dedicated button. When the eco indicator light on the dashboard is illuminated, 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 adopt 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 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 negatively 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, causing the eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the 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 under these conditions either.
The ECO mode in the Nissan Sylphy is essentially an energy-saving button on the car. Having driven this car for over three years, I find it particularly practical. During daily commutes stuck in traffic, pressing the ECO button to light it up activates the mode. At this point, the throttle becomes much gentler—a light press results in gradual acceleration, unlike the more aggressive response in normal mode, which helps save a significant amount on fuel costs. I frequently use it when driving in the city, and real-world tests show a fuel consumption reduction of about 10%, equivalent to saving several thousand yuan a year. Of course, there are minor drawbacks: it's best to turn it off during highway overtaking or uphill driving since it limits power output, causing slower acceleration. I recommend new owners try it out more often and develop the habit of activating ECO in areas with frequent traffic lights. Pairing it with smooth driving enhances the effect. Also, during car maintenance, check if the button functions properly to ensure minor issues don’t compromise fuel efficiency.
ECO stands for Economics mode, which means fuel-saving mode. In the Sylphy, you can activate it by pressing a button. I know a bit about how cars work, and the system intelligently adjusts throttle response and shift timing to make the engine run smoother and more efficiently—for example, by dulling the throttle and making the transmission upshift earlier, reducing instantaneous fuel consumption. In daily driving, using ECO can save about half a liter of fuel per 100 kilometers, making it easy to extend the range by dozens of kilometers on a full tank. However, the power response is weaker, and acceleration isn’t as sharp as in normal mode, making it more suitable for city commuting. I’ve also found that using ECO with the AC on during hot weather works well, balancing fuel efficiency. I recommend beginners start using it on low-speed routes first, then adjust based on their driving style once they get used to it.
