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.
  • Before replacing the main body ECU (multiplex network body ECU), refer to Registration.

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.
