  • Make sure to avoid lopsided loading on one side (left or right) of the vehicle and excessive loading.
  • Make sure to inflate the tires to recommended pressure, not higher than the specified pressure, when TPMS calibration is being performed.
  • Before you troubleshoot, review the general troubleshooting information.
