Guys, I just bought my 2008 last week. Not to sound like a jerk but RTFM.
See page 230. This reset tool is supposed to be provided to you free of charge. If you never received it make sure you get one.
Also, the TPMS is WIRELESS. the pvc can of air won't work I'm afraid... the sensor on the wheel looks like a hose clamp around it and it feeds to the computer via wireless. Lower on page 230 is the procedure for reseting your sensors.
