In everyday normal driving all year round on a Toyota (mine is an Avanza) passenger car with best fuel economy or lower fuel consumption, the Toyota's O/D Overdrive should be always ON ,meaning light off on dashboard.

Only when preparing for fast overtaking of cars in front or for very quick or heavy car acceleration, one should temporarily turn off the O/D (meaning pressing appropriate button (on gear shift stick column) leading to appearance of amber brown colour light on dashboard,, a few seconds or short moment BEFORE tekan minyak to overtake or accelerate the car.

Once overtaking or heavy/short acceleration is done or completed, one press the appropriate button AGAIN to turn on O/D Overdrive (meaning amber light OFF on dashboard) for everyday normal driving for low fuel consumption.
