Where is the Corolla ECO switch?

[DelBeckett]

The Corolla does not have an ECO switch. The ECO mode is merely an indicator light that signals when the vehicle is in a fuel-efficient state. The ECO function is a passive mode that operates automatically, activating only when the vehicle reaches optimal fuel economy conditions. This feature is now standard in many new car models, serving as a "fuel-saving and energy-efficient" control switch function. The ECO mode does not function under the following circumstances: 1. When the vehicle speed exceeds 120 km/h, priority is given to speed, and the energy-saving mode automatically deactivates. If the speed significantly exceeds the economical range (typically between 60-90 km/h), the ECO mode will not contribute to fuel efficiency. 2. The ECO mode primarily operates through the vehicle's computer during driving to maximize efficiency. Therefore, it does not function during idle stops, in N or P gear, or in manual mode. 3. When overcoming resistance and requiring high torque output, such as when climbing a hill, the ECU prioritizes delivering sufficient power to drive the vehicle, and the ECO mode will not engage.
