Okay...here's what happened: I've just finished a roughly 50 mile ride this afternoon on my GTS. It currently has just a little over 200 miles on it. The ride this afternoon consisted of about 15 city miles and the rest on a country highway. My speed never exceeded 60 mph and I always tried to keep it at 55 or below. As I was making my way back into town, I took off from a light and happened to look down as I cleared the intersection...the yellow "engine" light came on for about 5 seconds. I didn't think that much about it until it did the same thing again about a mile later. Obviously I will be calling the dealership tomorrow, but this happened after hours. And, unfortunately, I'm one of those lucky people who did NOT get an owner's manual with my GTS (it is apparently on its way). Anyone else have this problem? Any suggestions, comments, etc. :?
