overdrive button is located on gear shifter on automatice transmission.
The button does not switch from Overdrive to Automatic. The button just turns the overdrive off. Overdrive is not a separate drive system as your question implies. Normally you leave the car in overdrive mode. That way the transmission shifts into overdrive at highway speeds, thus saving fuel. If you are saying the transmission is stuck in overdrive and it will not disengage then seek out a A/T professional.
If you are refering to the button on the side of the shifter then it is the overdrive on / off button.Toyo joe
There is a button on the left side of the gear shift shaft, just underneath the shift handle (automatic transmission). Push the button to toggle the overdrive on and off.
In Nissan Sunny (and some other cars too), overdrive is ON when the button is DEPRESSED and there's NO LIGHT in the dashboard. The automatic transmission will utilise all the 4 forward gears (the 4th gear being the overdrive that helps in fuel economy -- similar to 5th gear in a manual gearbox). This is the recommended setting for normal driving. When the button is NOT DEPRESSED, you turn OFF overdrive, and the indicator LIGHTS UP in the dashboard. In this mode, the automatic transmission will NOT shift into 4th gear.

Are you sure you don't mean OD off light? If so, that means that the overdrive gear in your transmission is not activated. On automatic transmission models there is a button on the end of the shift lever which controls whether the transmission is in overdrive or not. Push in on this button - the light should go out and overdrive will be activated (which will definitely give you better gas mileage).
On a Toyota Camry, the overdrive button will be located either on or near the shifter. It will read 'overdrive' or 'O/D.'
