    • When the customer requests a change in a function, first make sure that the function can be customized.
    • Be sure to make a note of the current setting before customizing.
    • When troubleshooting a function, first make sure that the function is set to the default setting.

    HINT: 

    The following items can be customized.

    Key Low Battery Warning (Warning when key battery becomes weak) ON Function that warns driver that the key's battery power is low ON / OFF
  2. ENTRY UNLOCK MODE SWITCHING 
    NOTE:

    Because the electrical key (card type) does not have a wireless transmitter function, it cannot be used to change the entry unlock mode.

    1. Check that the power source mode is OFF and the LED on the electrical key is not blinking. Press the LOCK switch and one of the other switches on the electrical key at the same time for approximately 5 seconds while the electrical key is in the action area.
      • Driver door unlock default setting:

        When the switches are pressed and held for 5 seconds, the entry door unlock mode changes to the mode that is not currently selected.

      NOTE:

      After pressing and holding the switches for 5 seconds, wait 5 seconds before performing the same procedure again.

      • Driver door unlock mode:

        When the driver door touch sensor is touched, only the driver door unlocks. When any of the other touch sensors is touched, all doors unlock.

      • All door unlock mode:

        When any of the touch sensors is touched, all doors unlock.

    2. The certification ECU receives wireless signal from the entry door control receiver and changes the smart access system with push-button start to entry unlock mode.
    3. The certification ECU sounds the buzzers of the wireless door lock buzzer and combination meter to inform the user that the mode has been changed.

      HINT: 

      The procedure only changes the entry unlock mode of the smart access system with push-button start. It does not switch the unlocking of the wireless door lock control.

  3. ELECTRICAL KEY CANCEL 
    NOTE:

    Because the electrical key (card type) does not have a wireless transmitter function, it cannot be used to perform the entry key cancel operation.

    The electrical key cancel operation disables the following functions:

    • Entry Unlock / Lock
    • Entry Luggage Compartment Open
    • Electrical key Lock-in Prevention
    • Warning
    • Memory Call
    1. The operation procedure is as follows:

      Precondition:

      Engine switch off, driver side door closed and unlocked

      1. Unlock the driver side door once with the UNLOCK switch of the electrical key.
      2. Open the driver door within 5 seconds.
      3. Unlock the driver side door twice with the UNLOCK switch of the electrical key within 5 seconds.
      4. Close and open the driver door twice within 30 seconds.

        (Driver door: Close → Open → Close → Open)

      5. Unlock the driver side door twice with the UNLOCK switch of the electrical key within 5 seconds.
      6. Close and open the driver door within 30 seconds.

        (Driver door: Close → Open)

      7. Close the driver door within 5 seconds.

        When electrical key cancel is activated, the wireless door lock buzzer sounds twice.

        To return to the original condition, perform this procedure again. When the original condition is returned, the wireless door lock buzzer sounds once.
