My elantra 2007 (hd) doesn't have a OD button. So does this mean just use gear 3 in town?... go ahead and turn OD off around town if you like.
Does 'overdrive' mean 4th gear where the gear ratio to engine is smaller than 1:1? Little confused, because I saw on some cars, they actually have a OD button, and when turned off, it goes up to a higher rpm before next shift on every gear.
