Initializing Tire Pressure Monitor System: Notes
CAUTION:
Set tire pressure within the specified range before initializing. DO NOT push the reset switch without adjusting tire inflation pressure of all tires (including the spare tire). Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not performed.
The initialization process is canceled if the ignition switch is turned to OFF position prior to the completion of initialization. To restart initialization, the tire pressure warning reset switch must be pressed again.
