Typically Overdrive is engaged when cruising, when the car is in Top Gear. Whether the activation button is on the dash, or on the gear selector, makes little difference to how the Overdrive system works.
OD means Overdrive. The light is on because you have disengaged the Overdrive. The button is on the shift lever on the side. Push that button to engage the overdrive.
It kicks off electronic overdrive
The OD light on dash stands for Overdrive. There is a button (usually) on the end of the turn signal lever. Some cars the button or switch is on the dash. If you push the button/switch the light will change to OD or OD on (may even go out) then you will be in overdrive. Being in overdrive is good except for steep hills or pulling a heavy load.
On a 1995 Ford Explorer : Overdrive is the normally allowed position If you don't want the transmission to use overdrive ( such as when towing something , or if you are driving in hilly country where you notice the transmission is constantly shifting from overdrive to drive ) push the button on the end of your gear shift lever and the ( O/D OFF light should be lit up in your dash )
Keep the button for the overdrive engaged at all times and the vehicle will decide when it is needed. But if you prefer to determine when to use it yourself then its best to use it when your cruising the interstate. Its basically just a 4th gear that's designed to give you better gas mileage. If your "arrow" light is lit on the dash that means that your overdrive is off. If the light is off...your overdrive is on.
If you want the overdrive to be on, the light should be off on the dash. The picture on the button has the D in a circle with a line through it, just like a sign that says means "no smoking" & has the cigarette. Overdrive is always on when you start the vehicle.
Overdrive is the normally allowed position If the vehicle is shut off and then restarted , the overdrive will be allowed To turn off the overdrive feature , the button on the end of your gear selector has to be pushed and the O/D OFF light comes on in your dash ( if you push the button again the O/D OFF light will go out and the overdrive feature is allowed )
So first I do not have this vehicle. In general when you see overdrive light flash or stay on, it means overdrive has been turned on. In most vehicles the overdrive button is either on the gear shifter or on the stiring colum. If you dong want or need overdrive on then just press the button. If your light stays on, then it could be something different and not so simple.
If the light says off then your overdrive is turned off, push the button again and the light will turn off and overdrive will be on again.
yes i have overdrive button
If you don't want the transmission to shift into overdrive ( such as when towing a trailer , or driving in hilly country where the transmission is constantly shifting between drive and overdrive ) push the button on the end of the gearsfift selector ( P R N etcetera ) and the O/D OFF light will appear in your dash . Overdrive is the normally allowed position , but on my 1995 Ford Explorer doesn't shift into overdrive until I'm going around 50 Miles Per Hour
On my 1994 there is a button in the end of the gear shift arm. This turns off the overdrive and the dash says "Overdrive Off" above the odometer and gas mileage messages. Other than that, I don't know.
