Maintenance and care
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. ( P. 496)
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 size.
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 safe place and turn the engine switch off.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 615)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure
level.
Turn the engine switch to the ON position.

496 4-3. Do-it-yourself maintenance
Push and hold the tire pressure
warning reset switch about 3
seconds. After releasing the
switch, check that the tire pres-
sure warning light blinks slowly
three times.
Wait for several minutes with the engine switch on, and then
turn the engine switch to the ACC or LOCK position.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster 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 c annot 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.
