Linh, or anyone out there. I have a 2011 Sienna with TPMS, now required by law in USA. Each wheel has a transmitter that regularly sends pressure to car computer - if pressure is under some % of pressure in tire when the system is reset, the TPMS light comes on. I got a set of snow tires on new wheels and got them with the appropriate TPMS transmitters in them ($152+/- extra) and then discovered when I fitted them that they were not recognised, and that a Toyota dealer must (they have the only electronic means to do this) enter the new ID codes into the car computer. My dealer wanted $164 to do this.
BUT WAIT, IT GETS WORSE. When they enter the ID of the new TPMS transmitters, it erazes the originals - it cannot hold 2 sets - so that every time you switch wheels you have to go back to the Toyota Dealer and get robbed. I have confirmed this from Toyota!!!
You might consider, if you were happy looking after the tire pressures before TPMS, not getting the transmitters in your winter set, and just get used to the TPMS light being on all the winter, otherwise you will spend a fortune in time and money going back and forth to a dealer to get the IDs changed. This is a really Dumb system - even my wifes 2003 Mercedes which has TPMS can mange 2 sets of wheels, and it can even figure out which ones on the car without any intervention or trip to the dealer
