My tires are at the correct pressure. (i have tpms). The tires are new and have been rotated regularly. Warning Light on dash says"SERVICE TIRE SYSTEM SOON" Very little info in the manual...what does this mean? How do I clear the code...do I have to get the dealer to do it?

Try raising the pressure in each tire by 1 lb till the light goes out. But don;t go too high. I suspect your tire pressure guage might be old, and when they get old they read on the low side vs higher. Try a different one.

I have the same issue though. The message reads "SERVICE TIRE SYSTEM SOON". When tire pressure is low the message is different, it reads "x tire pressure low", where x is the number of tires with LOW pressure. There is no message with "x tire pressure high". Raising the pressure to have the "Service Tire Pressure Soon" will not help, if anything I suspect it will trigger the warning to appear. I have not tried to increase the tire pressure beyond the limits. This is NOT recommended. In my case the STSS message appear intermittently. I have noticed that it does tend to appear by -10 degrees C or less (14F or less) (yes it gets cold up here!)... so I suspect my TPMS sensors are getting old, and cold...
