I have a 2000 infinity i30 I think I'm driving with my overdrive on how do I know it off
In the shift handle there is a small button to turn on or off the overdrive. I believe it lights up an indicator on the dashboard as well. You want it ON since that means its using 5th gear on the highway and lowering your RPM's therefore saving you gas. I always got 25 MPG on my 1997 I30.
