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 tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer. (

Initializing the tire pressure warning system
■
The tire pressure warning system must be initialized when the
tire size is changed
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.
■
How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch to
the “ACC” or “LOCK” position.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (
→P. 548)
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.
Turn the engine switch to the “ON” position.
