I dont have my evo yet, but im getting it on saturday.... I saw when I was test driving it there was a button on the left of the steering wheel. ( not on the steering wheel ) Its the button that has the picture of the axle and the tires... I just want to know what it is, because my dad said he thinks it can control the percentage of rear wheel drive, front wheel drive, or 50% , 50% which would be standard AWD, but I find that extremely hard to believe, so I want to know what the button RAELLY does.
