CAUTION / NOTICE / HINT

Note


  • When replacing the object recognition camera, always replace it with a new one. If a object recognition camera which was installed to another vehicle is used, the information stored in the object recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

  • If the object recognition camera has been replaced with a new one, be sure to perform Object Recognition Camera Learning.
