Does the odoff light save fuel?

[MaggieLee]

odoff light can save fuel. When the od button on the gear lever is pressed, the dashboard will display the odoff indicator light, at which time the transmission will not shift to the overdrive gear and will only switch between 1st, 2nd, and 3rd gears. When rapid overtaking is needed, pressing the od key to drop to 3rd gear increases the engine speed and torque, allowing for quick acceleration by stepping on the throttle. When driving at low speeds in congested urban areas, activating odoff limits the transmission to gears below 3rd, reducing unnecessary switching of internal shift solenoids, while the vehicle being in a lower gear also facilitates speed increase. When the vehicle is going downhill, activating odoff can limit the transmission to gears below 3rd, utilizing the engine for auxiliary braking and reducing the need to step on the brakes.
