What does the ECO display in a car mean?

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed from the words 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 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 its own 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 turns on, it serves merely as a reminder function. The Eco mode 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, which means they have their own switch button. Therefore, during daily driving, we can generally enable the 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 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 during hill climbing, the engine's computer prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function in such scenarios.
I've been driving this car for several years, and when the ECO indicator lights up on the dashboard, it means the vehicle has switched to fuel-saving mode. This light usually comes on automatically during startup or while driving, reminding me that the system is optimizing engine and transmission performance to reduce fuel consumption—such as reducing aggressive acceleration response and adjusting shift timing, which saves quite a bit on fuel costs per kilometer. During my daily commute in traffic jams, turning on ECO really helps by preventing the engine from exerting too much power and wasting fuel. Of course, when driving on highways or needing quick overtakes, this mode can make the power feel weaker, so I've learned to manually turn it off by pressing the mode button on the steering wheel. Remember to perform regular maintenance and check system settings to ensure ECO doesn’t falsely report any faults.
