Caution / Notice / Hint

NOTE:
  • 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 it will not match the information from the vehicle and 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: Refer to TARGET ADJUSTMENT (ONE TIME RECOGNITION) [09/2020 - 11/2021]

    Sequential Recognition: Refer to TARGET ADJUSTMENT (SEQUENTIAL RECOGNITION) [09/2020 - 11/2021]
