What does Avalon ECO mean?

ECO refers to 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). The Eco mode is further divided into active eco driving mode and passive eco driving mode. When the ECO indicator light on the dashboard lights up, it indicates that the vehicle's economical mode has been activated. ECO mode is divided into active and passive 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 will immediately illuminate, and the vehicle will automatically begin adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive ECO mode does not have a dedicated button. When the dashboard ECO indicator light comes on, it serves merely as a reminder function. The ECO system automatically evaluates driving behavior, and if the 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 a dedicated switch button. Therefore, during daily driving, the ECO mode can be activated. However, it is unnecessary to enable ECO mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills—as this would not reflect the fuel-saving characteristics of ECO. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 km/h, the car prioritizes speed, and the ECO mode automatically deactivates. During idle parking or when in N/P gear or manual mode, 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 in this scenario either.
The ECO indicator on the Avalon refers to the Economic mode, also known as the Fuel Economy mode. When I drive this car, I often notice that light illuminated on the dashboard—it's essentially an energy-saving setting. When you press the ECO button, the vehicle adjusts throttle response and shift logic to make acceleration less aggressive, thereby reducing fuel consumption. In city traffic, I've found that activating ECO can lower average fuel consumption by about 1 liter per 100 km, which is quite practical. Toyota designed this primarily for congested road conditions to avoid frequent acceleration that wastes fuel. However, with ECO mode engaged, the power output becomes slightly weaker, making it less suitable for high-speed overtaking. If you frequently commute by car, try using ECO mode throughout your journey—it can save you a significant amount on fuel costs over time. The Avalon itself already has relatively low fuel consumption, and with this mode, it's even easier to maintain between 6-8 liters per 100 km. Remember, not all models enable it by default; just press the button when starting the car.
