CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.
  • When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.

    HINT:

    Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

    One Time Recognition: Click here 2021 - 2024 MY Camry HV [10/2020 -        ]; CRUISE CONTROL: FRONT CAMERA: TARGET ADJUSTMENT(ONE TIME RECOGNITION)

    Sequential Recognition: Click here 2021 - 2024 MY Camry HV [10/2020 -        ]; CRUISE CONTROL: FRONT CAMERA: TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION)
