TSB: 2015 model year IS 250 and IS 350 vehicles are equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (except the spare tire) has a tire pressure warning valve/transmitter and the measured tire pressure data is sent to the tire pressure warning antenna by electric wave and then sent to the receiver.
During Pre-Delivery Service (PDS), the TPWS must be initialized according to the procedure in this bulletin.
