CAUTION / NOTICE / HINT
CAUTION:
To prevent burns due to the heat of the windshield glass (heater), do not touch the area directly.
NOTICE:
- Inspect the fuses for circuits related to this system before performing the following procedure.
- 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 and a DTC may be stored.
- When the forward recognition camera has been replaced with a new one,
make sure to clear all stored vehicle control history of each system and
the forward recognition camera beam axis alignment data.
HINT:
Forward recognition camera beam axis alignment can be performed by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment Value Write".
