CAUTION / NOTICE / HINT

Note


  • When replacing the combination meter assembly, make sure to replace it with a new one.

  • Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

  • w/ Entry and Start System:

    Before replacing the certification ECU (smart key ECU assembly), refer to the smart entry and start system.
