Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, ti re pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warn ing valve and transmitter ID codes
must be registered in the tire pres sure warning computer and tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by Toyota dealer. 
(  P. 444)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances
●When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
● When changing the tire inflation pressure by changing traveling
speed or load weight, etc.
● When changing the tire size.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.
■ The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise. (P. 499)
The compact spare tire is not equipped with a tire pressure
warning valve and transmitter.

Registering ID codesThe tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a ti re pressure warning valve and
transmitter, it is necessary to regist er the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■ When to replace your vehicle’s tires
Tires should be replaced if:
● You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
● A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving
for about 20 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
