I have a '05 G35 Sedan with a full size spare. Does anyone know the procedure on how to reset the Low Tire Pressure Warning System? I had a flat and I need to reset the system so the dash warning light goes out. Does anyone know if the system senses the spare in the trunk also?

 

Mine just reset itself after I aired up the tire and restarted the car. I've heard others say that you have to drive for a few miles before it resets, but either way, it should do it on its own.
Check to make sure maybe one of your other tires isn't low.
