ENTRY UNLOCK FUNCTION

  1. The detection area is formed by communication between an electrical key antenna and the certification ECU when the door is locked in order to detect the person carrying the key.

  2. When the person carrying the key enters the detection area around the vehicle, the matching of the ID codes for an electrical key antenna and key is automatically performed. After the matching is completed, the door enters unlock standby mode.

  3. In unlock standby mode, the electrical key antenna built into the outside handle starts operating. If the outside handle is held (the back side of the handle is touched), the door unlock operation is performed. At this time, the hazard warning lights blink twice.

  4. If any of the doors are not opened after a door unlock operation, all the doors automatically lock after 30 seconds.


ENTRY LOCK FUNCTION

  1. After leaving the vehicle while carrying the key, touch the lock sensor on the outside handle or push the unlock switch on the luggage electrical key switch when all the doors are closed.

  2. The certification ECU determines whether the key is located inside or outside of the cabin based on the information from an electrical key antenna and indoor electrical key antenna. Then matching of the ID codes is performed.

  3. When the matching result shows that the key is not detected inside the vehicle and the ID codes of the key and electrical key antenna match, the door lock function operates. At this time, the hazard warning lights blink once.

  4. If the key is located inside of the cabin, the door lock function does not operate and the alarm buzzer (beep sound) sounds for 2 seconds.


ENTRY BACK DOOR UNLOCK FUNCTION
Stand in front of the back door with the key and push the unlock switch on the luggage electrical key switch to start the matching of the ID codes for the electrical key antenna. If the ID codes match, the back door unlock operation is performed.

BATTERY SAVING

  1. Vehicle battery saving function:
    While the entry and start system is operating, signals are emitted outside of the vehicle at a set interval (0.25 seconds) when the doors are locked. Therefore, the vehicle battery may be drained if the vehicle remains parked for a long time. For this reason, the controls listed below exist.

    Condition
    		Control
    Both conditions below are met for 5 days:
    1. Key is not in detection area
    2. Touch sensor or lock sensor operation is not performed
    		Signal transmission interval is extended from 0.25 to 0.75 seconds
    Both conditions below are met for 14 days:
    1. Key is not in detection area
    2. Touch sensor or lock sensor operation is not performed
    		Automatically deactivates the entry and start system
    Reinstatement Conditions:
    1. A wireless door lock control signal (lock, unlock) is input and the ID matches.
    2. A user carries the key and touches the lock sensor on a door outside handle assembly.
    3. The driver door is locked or unlocked by the mechanical key.

  2. Key battery and vehicle battery saving function:
    While the entry and start system is operating, 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 may be drained. For this reason, if this state continues for more than 10 minutes, the entry and start system is automatically deactivated.
    Reinstatement Conditions:

    1. A wireless door lock control signal (lock, unlock) is input and the ID code matches.
    2. A user carries the key and touches the lock sensor on a door outside handle assembly.
    3. The driver door is locked or unlocked by the mechanical key.
