If you don't move the sensors, your TPM will display in the DIC and you will hear beeps. If the system does not see the sensors, it thinks something is wrong.
I would recommend using them, they even help people like us out, who forget about our tire pressures from time-to-time.
The dealer cannot turn the system off, since it is required by Federal Law to be installed. (Feds can't come get you, so no problem there.)
If you do switch 'em from rim to rim, make sure the sensor goes in the same corner of the vehicle, to prevent having to relearn the sensors.
