Always on, unless you are traveling down a steep hill where you need the extra braking power the engine will provide. You might also want to turn it off if you are pulling a heavy load, which is highly unlikely in a car. OD will improve your gas mileage. Turn it off and your mileage will suffer.
If "OD Off" is lit, then your overdrive is off.
od light is the overdrive unit on the transmission. If you drive on the freeway you should have the overdrive unit on, on the streets the unit should be off. The light usually doesn't have anything to do with overheating. I would look for some other issue.
NO, OD off is mainly for increased braking/control when towing.
The OD button means "Over Drive", off or on.
there is a button on the gearshift or on 1 of the shifter rods on steering column
It should. If there is a switch on the dash or shifter lever that is labeled OD off, you will know for sure.It should. If there is a switch on the dash or shifter lever that is labeled OD off, you will know for sure.
Overdrive is basically the cruising gear. In a car with an automatic transmission, you can drive in OD all the time. You should be driving in OD anytime you are traveling over 40-45 MPH. (This is the speed at which your car will automatically) shift into OD if you have it placed in that gear to start with. OD saves strain on the transmission and I would speculate the drive train, also. Your car will coast more easily in OD and use less fuel. The only time I consider not using OD is when I am in town at speeds under 40 MPH.
When you see the OD off indicator on the dashboard, you drive the car with higher rpm. It gives you extra performance but shortens the lifetime of the engine.
What is the location of OD Button of Camary Car?
Many Ford automobile and pickup transmissions have an overdrive function. Most can be turned on and off with a push-on, push-off switch, . The lighted OD-off or indicates that the overdrive function is disabled, turned off. If, while the vehicle is running, you push the button adjacent to the indicator that says OD-off, you will turn on/enable the overdrive function. When the overdrive function is enabled, the OD-off lighted indicator goes of, and there is no indicator when the overdrive is engaged.
It means the car is set so that it doesn't shift into the overdrive gear. This is typically done during towing.
