CAUTION / NOTICE / HINT

NOTICE:

When replacing the radio and display receiver assembly, always replace it with a new one. If a radio and display receiver assembly which was installed to another vehicle is used, the following may occur:

·

A communication malfunction DTC may be stored.

·

The radio and display receiver assembly may not operate normally.



HINT:

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.
