Introduction
The 2011 model year Sienna is equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (except the spare tire) has a tire pressure
warning valve/sensor and the measured tire pressure data is transmitted to the Tire Pressure Warning System antenna/receiver to the Tire Pressure
Warning System ECU.
During Pre-Delivery Service (PDS) the tire pressure must be set to the specification and the TPWS must be initialized.
NOTE
The Tire Pressure Warning System valves/sensors are activated at the manufacturing plant. Only the initialization process is required during PDS.
