That's what I thought. So basically, there is no real point in turnig it off and on while normal driving, just leave it on all the time, and it'll do it's thing..
I have a button on mine for overdrive.
Is it safe turn it on while the car is moving or should I wait until I come to a complete stop before turning it on. I normally leave it off.

If you turn it off while driving, it'll just drop down to the previous gear if you're already in OD, and if you're not, it'll simply prevent the transmission from shifting up into OD.
As stated before, OD is a gear ratio higher than 1:1. Leaving a car in D as opposed to OD (or locking out OD) simply means the car won't shift up into OD. This prevents gear hunting and gives you more power to work with if you're towing something. (OD is designed for highway cruising. Low power output, but few turns of the engine to lower fuel consumption while maintaining highway speeds.)
Technically, ANY gear with a higher than 1:1 ratio is an overdrive gear, and technically, many cars have 2 or 3 overdrive ratios. (An Acura RSX 6 speed manual is an example of a car with 3 overdrive ratios.)
In most (automatic transmission) cars, it simply means 4th gear. Turning it off via the little button on the shifter (or switching the lever from OD to D or 3) means that the automatic transmission will not use 4th gear.

a lot of you are saying it's great for highway cruising... but what if you're just driving around town... wouldn't the 1:1 non-OD still use up more gas ? Wouldn't OD still serve you better on local roads... where even then you don't really need the power ?
you guys are horrible at answering questions. 4 posts aimed at me and I still have no answer.
yes or no : Is it safe (for the car) to push the over drive button while moving in an automatic or should I come to a stop first.
in other words, If I drive on the highway non-stop for an hour and toggel the overdrive on and off like 30 times. Will I damage the car?

If you do anything too frequently, you are bound to break something - yeah, even works for sex
I turn OD on and off while my car is in motion. I have been using it like this for the past 6 years. I get about 30-32 mpg on my 6 year old Corolla. I have driven a stick shift before and I figured I would use the overdrive button as if I were shifting into 4th or downshifting to 3rd while taking corners. Works fine for me, so far

Hmm... if it were really that bad, do you think they'd allow it to be engaged while the car was in motion ? There's a reason why you can't shift to Reverse without depressing the shift unlock first (meaning you really meant to do it)... every other gear (except for Park) can be shifted to without pushing the unlock first. That's cause shifting gears (4,3,2,1) while the car is in motion is ok... even if you did it accidentally.
Listen to your dad. He knows what he's talking about. Bet he drops it down in 2nd gear when he's in 30mph traffic, also.
