HINT: 

If the rear bumper assembly is damaged, there is a possibility that the installation area of the blind spot monitor sensor may be deformed and the blind spot monitor system may not operate correctly. Visually inspect the blind spot monitor sensor installation area (vehicle body, stud bolts) to make sure it is not damaged.

Refer to ADJUSTMENT [10/2022 - 11/2023]

If damage is found in the visual inspection, check the installation condition of the blind spot monitor sensor, and adjust the installation position of the blind spot monitor sensor as necessary.
