    10. Battery Saving


      1. Vehicle Battery Saving Function

        In the entry and start system, signals are emitted outside the vehicle at a prescribed interval (250 msec.) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below are effected.

        Condition Control
        No response from key for 10 to 14 days Signal transmission interval is extended from 250 msec. to 750 msec.
        No response from key for 15 to 30 days Signal transmission interval is extended from 750 msec. to 2250 msec.
        No response from key for more than 31 days Automatically deactivates entry and start system.
        Reinstatement Conditions
        A wireless door lock remote control signal (lock and unlock) is input and the ID matches.
        A user is carrying the key and pushes a lock switch on an door outside handle.
        A door is locked or unlocked using the mechanical key.

      2. Key Battery and Vehicle Battery Saving Function

        In the entry and start system, if the key is constantly located within the vehicle exterior actuation area of the doors, the system will maintain 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 entry and start system automatically deactivates.

        Reinstatement Conditions
        A wireless door lock remote control signal (lock and unlock) is input and the ID matches.
        user who has the key in their possession pushes a lock switch on an door outside handle.
        A door is locked or unlocked using the mechanical key.

    11. Key Cancel


      1. Key cancel is operated when certain operations are performed with the vehicle in the following condition:


        • Engine switch is OFF.

        • Driver door is closed.

        • Driver door is unlocked.

      2. The operation procedure is as follows:


        1. Unlock once with the UNLOCK button on the key.

        2. Open the driver door within 5 seconds.

        3. Unlock twice with the UNLOCK button on the key within 5 seconds.

        4. Repeat open → close twice for the driver door within 30 seconds, and open again. (Driver Door: Open → Close → Open → Close → Open)

        5. Unlock twice with the UNLOCK button on the key within 30 seconds.

        6. Repeat open → close once for the driver door within 30 seconds, and open again. (Driver Door: Open → Close → Open)

        7. Close the driver door within 5 seconds.

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

        To return to the original condition, perform the procedures again. When it is returned to its original condition, the wireless door lock buzzer sounds once.

    12. Key Code Registration Function


      1. The table below shows the four special coded ID registration function modes through which up to seven different codes can be registered. The codes are electronically registered (written to and stored) in the EEPROM.

        Mode Function
        Rewrite Erases all previously registered codes and registers only the newly received codes. This mode is used whenever a transmitter or the integration relay is replaced.
        Add Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter. If the number of codes exceeds 4, the oldest registered code is erased first.
        Confirm Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.
        Prohibit To delete all the registered codes and to prohibit the wireless door lock function.This mode is used when a transmitter (key) is lost.
