Check and make sure your tire pressue is correct! Then, you need to re-activate the tire pressure sensor in the center information display. You push the left end button until you see "tire pressure..." re-active press "-" and "+"... if i remember correctly. Please check your owner's manual. Hope this helps.

IF the message is truly "TPMS inoperative," then your sensors were damaged or removed.

I'm with Kent. I've not seen that message before, only "adjust tire pressure." I recommend revisiting the shop that repl'd yr tires and ask dor an explanation.
