Caution / Notice / Hint

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2024 Lexus ES 350, 2024 Lexus ES 250, 2023 Lexus ES 350, 2023 Lexus ES 250, and 2022 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
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 ADJUSTMENT [06/2018 - ]

    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.
