Thanks, Borksi. Only way I found to engage ACC was to push in on the horizontal silver bar on the stalk above the 3 button array with the cruise control icon, the distance icon, and the “X” to disengage. I thought the lower, left hand “cruise control” icon would engage ACC. No such luck. Depressing the silver bar that was part of the +/- 1 or 5 MPH increments was, ultimately, the only reliable way to engage ACC.
I have not looked at the manual on the iPhone app and the little booklet in the glove box labeled “owner’s manual” is surprisingly lacking in detail and seems mostly many pages of warnings.
Any other thoughts would be appreciated. Overall the Air is AMAZING. Truly impressed. Thanks for your leadership with these pages.
