Caution / Notice / Hint

NOTE:
  • When checking for DTCs, make sure that the blind spot monitor system is turned on.
  • If the bumper is damaged or the vehicle has a history of body repair, there is a possibility that the installation area of the blind spot monitor sensor may be deformed and the blind spot monitor sensor system may not operate correctly, so visually inspect the blind spot monitor sensor installation area (frame, stud bolt) to make sure it is not dented or bent.

    Refer to OPERATION CHECK [10/2016 - 09/2020]

  • If the visual inspection finds a problem, check the installation condition of the blind spot monitor sensor, and adjust the installation position of the blind spot monitor sensor as necessary.
