    Refer to INITIALIZATION [12/2017 - 10/2023]

    Refer to CUSTOMIZE PARAMETERS [12/2017 - 10/2023]

  • After the catch protection function operates, the auto operation is not performed the first time auto up is performed. All auto up operations performed after the first operate normally.

However, the power window can be closed by holding the rear power window regulator switch assembly RH at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly RH.
