Hello. I am the new owner of a Galant 2007 ES, and I am looking for where the overdrive button or switch is located in the car. My in town mileage is very good, but highway mileage is relatively poor with high rpm's.

Thanks.

 

As far as I can tell, when you put it in the D4 position, that is it, no OD button. If you feel your gas mileage is bad, you may need a tuneup. Air filter, plugs and so on. Even check your tire pressure. O2 sensors could be dirty as well. Hope this helped. Keep us up to date. Good luck.
