Tire inflation pressure warning light 

  This light illuminates if the inflation pressure of any tire (except for compact spare tire) drops while the 

ignition key is in the  “ON” position. It normally illuminates when the ignition key is turned to the  “ON” 

position and goes off a few seconds later. 

 

If the warning light illuminates while driving 

Avoiding hard braking, hard steering, and high speeds, drive to the nearest gas station or authorize car dealer 

and adjust the tire inflation pressures.(except for comp act spare tire) 

 

If the warning light blinking while driving 

It is thought abnormality of the device, go to the check to the nearest car dealer as soon as possible. 

 

Whenever the tires and wheels are replaced with new ones 

  Tire inflation pressure sensors must be fitted on the new wheels and their ID codes must be programmed into 

the system. Have tire and wheel replacement performed by an authorized car dealer to avoid the risk of 

damaging the tire inflation pressure sensors.
