      To activate the starter:

      1. Turn the engine switch from off to on (ACC).
      2. Hold pressing and hold the engine switch for 15 seconds.

    After the certification ECU (smart key ECU assembly), steering lock ECU, ID code box (immobilizer code ECU) and/or ECM are/is replaced, perform the registration procedures for the engine immobilizer system. Refer to REGISTRATION [08/2012 - ] .
