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.
  • If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.

  • When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket or the forward recognition camera may not operate properly due to a difference in the transmissivity or black ceramic border.
  • Forward recognition camera optical axis may deviate if the vehicle is driven on a banked road, such as a racetrack. This deviation can be corrected by driving the vehicle on a normal road for a while.
  • Forward recognition camera optical axis may deviate when the vehicle is overloaded or the wheel alignment (toe-in) is incorrect. The forward recognition camera optical axis can be corrected by decreasing the load on the vehicle or adjusting the toe-in.
