Reset Procedure

TIRE PRESSURE WARNING RESET SWITCH

By operating the tire pressure warning reset switch, the tire pressure warning ECU can be set to issue a warning at an inflation pressure that corresponds to the type of tires. Therefore, the dealer must set the warning threshold to the proper value in order to comply with local regulations.

Operate the tire pressure warning reset switch only after the inflation pressures of all tires (including the spare tire) have been adjusted on the vehicle.

To initialize the system, press and hold the tire pressure warning reset switch for 3 seconds or longer with the engine switch on (IG). When the system receives the initialization signal, the warning light blinks 3 times (1 second on, 1 second off).

During initialization, the tire pressure warning valve and transmitters measure the inflation pressure of the tires, and register the signals that are transmitted into the tire pressure warning ECU at a frequency of once per minute. The initialization process is completed when signals from all tires (including the spare tire) have been received.
