You'll need a TPMS trigger (which you didn't say you had, so I'm mentioning it). The one I have is overkill and it's called a VT-15, I think. Anywho, with the engine running or in service mode (with your foot off the brake hold the Start button for 10 seconds and the car will fully start up all systems except for the engine), switch to the tire pressure screen in the DIC (gauge cluster screen) and hold in the select button until your horn beeps. Then hold the trigger tool near the inflation tube of the front driver's side wheel (mine actually triggers better through the tire treads than right next to it through the rim) until your horn beeps. Repeat at the front passenger, then rear passenger, then rear driver. On the last one, the horn will beep twice and you're done.
