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 regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and trans-
mitter ID codes registered by your Toyota dealer. (

Initializing the tire pressure warning system
n The tire pressure warning system must be initialized in the fol-
lowing circumstances:
l When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
l When changing the tire size.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.
n How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the engine switch off.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. (
