To turn off eco mode on Your 2019 Toyota Sienna by holding the "disp" button on the steering wheel for a few seconds until the option appears. You must be in odometer mode.The ECT Power setting is good for temporary boosts of power when hauling a heavy load from a small stoplight, going up a hill, or passing. However, it also changes the transmission shift points and prevents it from selecting the highest overdrive gear, so I would not leave it on all the time.It does not harm Your engine or gearbox to leave it on. However, You cannot reap any benefits by using this setting while driving aggressively (hard acceleration and sudden braking).

On a 2019 toyota sienna, you can disable eco mode by holding the "disp" button on the steering wheel for a few seconds until the option appears (you must be in odomoter mode, i guess). Le eco upgrades alone have an "eco mode"-and an eco button.
