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".
