PSI light on after tire change

I just got back home from getting my winters on at Costco and my PSI light came on just after I left. I tried the rotation instructions in the manual, and it doesn’t seem to have worked. Since this is a brand new car, I’m assuming it’s a sensor issue and not a tire issue. Is it (likely) safe for me to drive for a day or two until I can get it back to the garage?
