What are you guys running for tire pressures, especially the rears. The recommended tire pressure is 47psi according to the door panel.

 

That 47 psi is for full load. Use the display to set pressure, as I recall for partial load/comfort it's around 32 fr and 36 rr.
The dash screen will let you go to the TPMS screen and then a submenu, you can select appropriate situation (full load, partial load, comfort, sport, etc.) and it will simply display how far up or down pressure needs to go.
I'm doing this from memory, as I'm not near the car now. Can give you exact info next week, lol. But DON'T go off the door tag...the car will be VERY floaty and wander very much.
