Overdrive is the normally allowed position ( in overdrive the engine doesn't rev as high , the gas mileage is better , the transmission will run cooler etc. when you drive at higher speeds )
No, just the opposite. Overdrive is an extra gear, the use of which, make the vehicle more economical.
when you are drivin long distances at a higher speed, it is better to use the overdrive just for gas mileage. i wouldn't recommend using it around town due to the fact that it may cause your tranny to shift a lot more causing more wear
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.
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.
No it will not give you better performance or increase gas mileage. Gas mileage and performance will decrease only if you use it. leaving it off is like not having it at all.
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).
It should be on for best gas mileage under normal driving conditions, If towing a large load up hills and through town, it should be off.
That's your overdrive button ( the top " gear " of your automatic transmission ) If the overdrive is switched off the O/D OFF light will be illuminated in your gauge cluster Overdrive is the normally allowed position , it is used on the highway / freeway and allows the engine to run at a lower RPM ( Revolutions Per Minute ) when the vehicle speed is faster , it helps you get better gas mileage and the transmission will run cooler
I believe overdrive should automatically be enabled on any car. Overdrive allows a car to drive at fast speeds with low engine input (low revs) resulting in better gas mileage. The downside is that you lose torque. You should be able to turn it off for things like climbing mountains and using engine breaking to go down them. Unless you turn it off, it's already on.
Off for better gas milage , hwy or city for that matter
Overdrive keeps your engine RPMs low when you drive faster than 45 mph Its there for fuel economy If you drive without OD it doesnt hurt anything at all except your gas mileage
