I've an '05. I put the spare into service, which has no TPMS, but it didn't trip on the dash warning light. What the *bleep* I thought it would turn on the light, but no. The dash light definitely is working, so it's not as if the bulb is burnt out. I'm flummoxed as this makes no sense Anyone else experienced this? The tires have to rotate in order for the computer to get a reading...right?
