I wasn't needing to go over mounds of snow so I put her back in her place at normal ride height. That select-terrain sure is a smart fella.
Your vehicle didn't automatically switch into Sport mode, it went into Aero mode which is 0.5" lower than normal ride height. As far as I'm aware that's the extent of what Aero mode does - it doesn't change shift points, torque splits, etc. That would require turning the dial to put the vehicle in Sport setting, which in addition to putting the vehicle in Aero mode also reduces the traction control, changes shift points, and changes the torque to give the rear wheels up to 80% torque.
As for the vehicle automatically raising into OR1 position, I really don't think it did that based on temperature or road conditions. Even putting the vehicle into snow mode doesn't affect its ride height - it stays at Normal Ride Height. I could be wrong, but I haven't seen anything anywhere in the manual to suggest that's possible.
