◆Registering ID codes
Vehicles without a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of tire pressure warning system se nsor
ID codes initially registered to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes ca n
be registered at your Toyota dealer. When 2 sets of ID codes ha ve
been registered, either ID code set can be selected.
Vehicles with a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmit ter,
it is necessary to reg ister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the multi-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are reg istered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch disp lay)
or (7-inch display) of the multi-information display. It is no t nec-
essary to reregister the ID codes each time the wheels are
changed.
For information regarding changing the registered ID codes for an
ID code set, contact your Toyota dealer.
