I did some Air Ride testing this weekend on a long trip through the Hill Country. Here are my observations: Apparently, it depends on what setting you start in. Starting off in "Normal," if I clicked down 2 times quickly, it went straight to E/E not pausing at "Aero." Then, it would automatically rise to Normal at 15+ mph. And continuing on to highway speeds, it automatically lowered to Aero after 30 seconds or so over 60 mph, as one might expect. Interestingly, it stayed in Aero mode until I came to a nearly complete stop before raising back to Normal. However, if I started off in Aero and clicked to E/E while stopped, it would raise to Aero at 15+ and stay there at all speeds, even 70+ mph and all the way back to a stop and just stay there, until you changed it manually. The big difference seems to be the ability to place it in Aero manually and leave it there. I don't think I could do that with my '14. However, I never could replicate it staying in E/E through an entire trip which included highway speeds as my wife claimed happened to her. However, I can verify that it was in E/E when she left and E/E when she returned and she says she never touched anything.
