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.


·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.



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 Navigation System.
