Re: Exchanging Wheels TPMS
I believe it is under "settings" then choose TPM then "reset" confirm with "yes". If in doubt you can always referr to the owners manual.
If you replace the wheels and you dont install the TPM sensors then yes, you will always have a tire malfunction warning on and no, you cant shut it off.
Check the valve stem area (inside of wheel) on of the 19's, if it has a flat area aorund it then the TPM sensor "should" fit on the 19" wheel.
