I would still take it to the dealer to see if they can pull a code. With the CVT, I would not take any risks.generator said:Thanks for all replies.....This morning I tried the Ds mode again BUT this time it acted normal. Shut the car on and off 2 or three times to see if it would come back. Now my car does not rev in the 5000-6000 rpm range. It sort of coasts around 4000. I dont know why my car was acting weird before. It may be because I was driving for over two hour to Six Flags before I played with the shifter. I was almost at my destination when my passenger asked me what the S was for and I attempted to show it. Thats when it got scary. All seems OK for now.
