What does it mean when the ECO light is on in a Toyota Vios?

When the ECO indicator light is on, it indicates that the vehicle's economy mode has been activated. ECO stands for the car's economical driving mode function. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). ECO mode is divided into active and non-active types. The difference lies in the fact that the active type has its own button, allowing the driver to choose whether to activate it. When the driver presses the ECO mode switch, the dashboard indicator light will immediately turn on, and the vehicle will automatically start 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 dashboard ECO indicator light is on, it is merely a reminder function. ECO will automatically assess your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars use the active ECO driving mode, which means they have their own switch button. Therefore, during daily driving, you 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 reflect the fuel-saving characteristics of ECO and could also affect the vehicle's power. In addition, ECO mode usually becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car will prioritize speed, and the ECO mode will automatically deactivate. During idle parking or in N/P gear or manual mode, ECO may also become ineffective. When a large torque output is required, such as when climbing a hill, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will not work either.
