Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by your Toyota dealer. (P. 465)

Initializing the tire pressure warning system

The tire pressure warning system must be initialized in the fol-
■
lowing circumstances:
● When rotating front and rear tires which have different tire infla-
tion pressures
● When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system

■
1 Park the vehicle in a safe place and turn the engine switch to the
"LOCK" position (vehicles without a smart entry & start system)
or off (vehicles with a smart entry & start system).
Initialization cannot be performed while the vehicle is moving.
2 Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 607)
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
3
Turn the engine switch to the "ON" position (vehicles without a
smart entry & start system) or IGNITION ON mode (vehicles with
a smart entry & start system).
