I just disabled my TPM system by following some of the instruction on this thread. At first I was very skeptical about pulling anything off because of fear that some of the clips might break. As it turned out, it was very easy. Here are the detailed instructions.
1. Put on emergency brake just in case you're on an incline because you will need to put the shifter on 2-L
2. Open the console - both the top cover and the tray
3. Using your thumbs, placed them on the back portion of the small panel for the seat heater switches. Push or pull up. Once the back come off, grab the panel and giggle a little bit while pulling up - not too hard. Disconnect the electrical plug from the back.
4. Wih the panel for the seat heater switches off, you will see two clips holding down the wood panel around the shifter. I pushed the two clips up (just to make sure there's no strain on the clips) while pulling up the panel slowly.
5. Once the back potion of the wood panel is off, giggle left/right a little bit while pulling the panel towards the back - to disenage the two clips right below the radio. There are two "claws" on the left and right side of the panel. This is why you lift a bit while pulling back.
6. Once the wood panel is off. place a rag underneath (to prevent scratches) and pull back as far as the two wiring harnesses will allow. If your hands are small, you can reach for the two plugs on the TPM unit right below the radio (picture in this thread). Pull/disconnect the plug.
7. Reinstall the wood panel by with the front clips (below the radio) first the do the reverse, i.e., push forward while pushing down.
8. Reconnect the plug of the seat heater and resintall the small panel.
That's it!
