CAUTION / NOTICE / HINT

NOTICE:: ·

Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.

·

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:: ·

The meter illumination dims when the taillights are turned on.

·

Setting the meter illumination level to maximum brightness cancels the above dimming of the meter illumination.

·

Setting the meter illumination level to minimum brightness turns off the meter illumination.

·

The automatic light control sensor sensitivity can be customized.
