When the mode is turned on "Overdrive" (overdrive) the box automatically upshifts to second, third and fourth (boosting) gears. If the mode switch "Overdrive" disabled, the transmission will not upshift to fourth (boosting). Under normal driving conditions, the selector should be in position "D" and the mode switch is on "Overdrive».
If you need to quickly pick up speed, fully depress the gas pedal. The box will automatically downshift, depending on the speed and load of the engine.
