What is the RAV4 ECO mode?

[LaQuinn]

ECO refers to the car's economic 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 illuminates, it indicates that the vehicle's economic 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. Non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates driving behavior. If the current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning 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 these conditions do not reflect the fuel-saving characteristics of Eco mode. 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.

We veteran RAV4 drivers all know that pressing the green leaf button on the center console activates ECO mode. The instrument cluster turns green, throttle response becomes noticeably gentler, and the transmission shifts up more eagerly. Last time I drove in ECO mode throughout suburban roads, the displayed fuel consumption was only 6.9L, nearly 1L less than normal mode. However, acceleration does feel sluggish in this mode - you need to floor the pedal for response when overtaking, so I recommend temporarily disabling it before highway overtaking. The smartest part is even the AC automatically adjusts to energy-saving mode, making cooling slightly slower when using air conditioning in summer.

Ride-hailing drivers all know that ECO mode can save some fuel costs. Last week, I specifically compared: in city traffic jams, using ECO mode saves 0.8L of fuel per 100 kilometers, which translates to saving four cents per kilometer. However, it's not cost-effective for long-distance trips—cruising on the highway in ECO mode keeps the engine RPM too low, causing frequent downshifts when climbing slopes. It's recommended to use the energy-saving mode on flat roads and switch to normal mode when encountering long slopes. Don't expect the air conditioning to blow icy cold—ECO mode limits the compressor's power.

Simply put, ECO is the economy driving mode. The principle is straightforward: it restricts throttle opening, delays throttle response, and prompts the transmission to upshift earlier. When driving the RAV4 Hybrid, I observed that in normal mode, it upshifts to 4th gear at 40 km/h, while in ECO mode, it achieves the upshift at 35 km/h. However, avoid using this mode on mountain roads—during uphill climbs, the engine speed is held below 1,500 rpm, causing the engine to emit a muffled lugging sound. It's quite suitable for urban commuting, with fuel-saving effects that are visibly noticeable.
