Car ECO is a fuel-saving mode indicator light, which can be turned off in the settings menu on the display in the middle of the dashboard. Below are the specific details about the ECO mode: 1. ECO is a fuel-saving mode indicator light. When activated, the vehicle's computer will alter the standard shifting logic, and the throttle response will also slow down to achieve fuel-saving effects. In active ECO driving mode, when the optimal fuel supply is reached, the dashboard will simultaneously display a green "ECO" indicator. If you press the accelerator pedal hard to accelerate or encounter an uphill section, the "ECO" indicator will disappear. 2. Activating the ECO mode allows the vehicle to automatically match the best gear and RPM to reduce fuel consumption. At the same time, the driver needs to actively control the throttle and brake to achieve the most ideal fuel consumption. Non-active ECO driving mode only serves as a reminder and guidance function.

Last time I drove my friend's Hyundai ix35 with the ECO button, I also spent quite some time figuring it out. When I reached below the center console, there was a physical button with a small green leaf icon. Pressing it made the annoying 'ECO' display on the dashboard disappear. Some cars, like Volkswagens, require going into the driving mode menu on the center screen and selecting 'Normal' or 'Sport' mode. After turning it off, the throttle response indeed became much sharper—no more waiting half a second when overtaking by pressing the accelerator deeper. But you’ll notice the fuel consumption numbers creeping up quietly. If you plan to keep ECO off long-term, it’s advisable to develop anticipatory driving habits to balance out the fuel consumption.

With a decade of car repair experience, I've seen various ECO mode designs. Japanese cars like the Corolla Hybrid have a prominent green button on the right side of the steering wheel's functional area—pressing it releases engine restrictions. German cars such as the Audi A4 require turning the central console's driving mode dial to Dynamic mode. The most troublesome are those integrated into the infotainment system, requiring navigation through three layers of menus like operating a smartphone to deactivate. A word of caution: prolonged deactivation may lead to increased carbon buildup, especially in stop-and-go city traffic conditions. It's advisable to engage Sport mode monthly to rev the engine higher and help clear out carbon deposits.

Last month I just helped my daughter adjust the ECO mode on her Vezel. By rotating the circular drive mode selector next to the gear shift knob from green ECO to blue standard mode, the transmission immediately felt much more responsive with quicker downshifts. New car designs are getting more complex nowadays - like the NIO ET5 where you have to navigate through the 12.8-inch touchscreen to find Vehicle Settings - Driving Options. Two important notes after turning off ECO: avoid aggressive throttle during cold starts when transmission fluid temperature is low to prevent clutch plate damage; and feather the throttle when turning off in rainy conditions as sudden torque release may cause wheelspin.

There's a trick to turning off ECO mode in my domestic SUV. First, press the '*' custom button on the left side of the steering wheel to bring up the quick menu, then use the directional keys to select driving mode. The key point is that the vehicle defaults to ECO mode upon each restart, so you need to disable 'Remember Driving Preferences' in the system settings. The mechanic at the tuning shop mentioned that for models with start-stop functionality, it's best to turn off the start-stop system simultaneously when disabling ECO to avoid excessive battery drain. If you've modified the intake and exhaust systems, the effects are more noticeable after turning off ECO, but be sure to check the oxygen sensor data.
