1. Make sure the engine is warmed up and turned on.
2. Locate the overdrive switch in the center console. It should have an "O/D OFF" or similar label.
3. Press the overdrive switch to turn it off. The overdrive indicator light should turn off on the dashboard.
4. Select the desired gear using the gearshift lever.
5. Accelerate the vehicle to the desired speed.
6. Press the overdrive switch to turn it back on. The overdrive indicator light should turn on the dashboard.
The vehicle will now use the overdrive gear, which is a higher gear ratio that allows the engine to run at lower RPMs while maintaining the same speed. This can help to improve fuel efficiency and reduce engine noise at higher speeds.
