I figure that if was initialized at 46 psi then it should alarm at a higher pressure than it it were initialized at the correct pressure. When I go to the dealer I will tell them that they screwed up checking the pressure and I want them to reinitialize it.Finally found the right menus to re-intialize. Hit a long ok. Light blinked and went out. Drove (probably not long enough), got home. Went to tire pressure monitor menu......goose eggs. I will either have to drive more and hope backing up does not screw up the process or start again.
