Hello. New to this web site. I have a 2005 997 with 50,000 miles. Last week my battery died so I got a jumop start and took the car home. I noticed the next day when I used the car that the Sport button on the lower left of tghe dash board would not light up when I pushed it. The sport mode is not working. Any idea what's wrong?? Do I need to reset some thing or is it just a fuse that I need to replace.

Thanks
