CAUTION / NOTICE / HINT
- NOTICE:
- ·
When replacing the forward recognition camera, 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 and a DTC may be stored.
·When the forward recognition camera is replaced with a new one, make sure to perform beam axis adjustment 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.
