1. Ensure that the vehicle is in motion.
2. Locate the overdrive button. It is usually a small switch located on the gearshift lever or near the center console. The overdrive button is marked with the word "Overdrive" or an "O/D" symbol.
3. Press the overdrive button to turn off overdrive. The overdrive indicator light on the instrument panel will turn off, indicating that overdrive is disabled.
4. When the vehicle is at the desired speed, press the overdrive button again to turn overdrive back on. The overdrive indicator light on the instrument panel will turn on, indicating that overdrive is engaged.
Overdrive is a fuel-saving feature that allows the vehicle to operate at a lower engine RPM while maintaining the desired speed. This can improve fuel efficiency, reduce engine noise, and reduce wear and tear on the engine and transmission.
