What is O/V off. on the dash board...
Or what is the button on the stick. O/V button???

i believe u are reffering to the o/d (overdrive) button which ive heard basically gives you slightly better acceleration, but mainly it just takes away your last gear when it is on so u run at a higher rpm, and its not the smartest thing to have on in highway driving unless u like the gas prices.

I agree with Archer, it's probably the Overdrive. For me, it feels like the car accelerates faster with the O/D turned off, but its harder on your engine and crushes your gas mileage...

Yep, its the overdrive button. If you press it while driving you will feel the sort of jerk as it shifts back down. The overdrive shifts the car into 4th gear when you are cruising at a constant speed.
