Correct Usage of the Automatic Transmission OD Switch

[DiTravis]

When the car is driving at high speed, you can turn the OD switch to "on," which can help the car achieve fuel-saving effects. When the car is climbing a slope, you can turn the OD switch to "off," which will lock the gear within the third gear. When going downhill, turning the OD switch to "off" can prevent the transmission from shifting to the fourth gear too quickly, reducing the frequency of braking and lowering the car's downhill speed accordingly.
