I have a 2007 model with a NOV/2006 build date...NO TPMS!!!
At first, I was disappointed in the fact that I had no TPMS, only the system the rest of the automotive world uses outside of the USA.
Now I am soooo happy that I don't have to mess with having to install a set of $300+ sensors in my wheels!
Be happy you don't have TPMS!
