I just purchased a 2001 Viggen convertible and when the PO showed me putting the top down, it had an "S" at the bottom of the climate display and he told me that indicated Sport mode. Since I got it home, I have yet to see that same "S" on the display at any time and am curious why it was there and what it meant, and how does it come back? So far, I have been very impressed with the Viggen and it has far exceeded my expectations.
