DESCRIPTION
Initialization is necessary if one of the following occurs:
Tire pressure warning initialization is performed when the steering pad switch assembly is operated with the ignition switch to ON, "TPMS" is selected on the multi-information display and the "ENTER" switch (steering pad switch assembly) is pressed and held.
The tire pressure warning ECU and receiver flashes the tire pressure warning light of the combination meter assembly 3 times and registers the tire pressure sent by the tire pressure warning valve and transmitter after receiving an initialization command signal.

PROCEDURE
1. |
CHECK FREQUENCY RECEIVING CONDITION |
(a) Check that the following conditions are not met:
(1) Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
HINT:
If the vehicle is located in an area such as the one described above, the tire pressure warning light may illuminate after blinking 1 minute only in a particular area due to interfering radio frequencies.
(2) Devices using similar radio frequencies are used in the vehicle.
OK:
Facilities or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
HINT:
Radio transmissions may be interrupted due to the surroundings or devices installed by the user.
