CAUTION / NOTICE / HINT

NOTICE:
·

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.

·

When replacing the combination meter assembly, update the ECU security key.
