      Both conditions below are met for 30 days
      • Key is not in detection area
      • Touch sensor or lock switch operation is not performed
      		 Automatically deactivates the smart access system with push-button start

      Reinstatement Conditions

      • A wireless door lock control signal (lock, unlock) is input and the ID matches.
      • A user carries the key and pushes a lock switch on an outside door handle.
      • The driver door is locked or unlocked by the mechanical key.
    2. Key battery and vehicle battery saving function-In the smart access system with push-button start, if the key is constantly located within the vehicle exterior detection area of the doors, the system maintains periodic communication with the key Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could be drained For this reason, if this state continues longer than 10 minutes, the smart access system with push-button start automatically becomes deactivated

      Reinstatement Conditions

      • A wireless door lock control signal (lock, unlock) is input and the ID code matches
      • A user carries the key and pushes a lock switch on an outside handle
      • The driver door is locked or unlocked by the mechanical key
