    Jam protection The jam protection function automatically stops the sliding roof and moves it open half way (or fully tilt up) if a foreign object gets jammed in the sliding roof during close or tilt down operation.
    Key-off operation The key-off operation function makes it possible to operate the sliding roof for approximately 43 seconds after the engine switch is turned on (ACC) or off, if the front doors are not opened.
    Key-linked open and close

    • When the key is not in the vehicle, the driver side door is unlocked, and the driver door key cylinder is turned and held in the unlock direction for 1.5 seconds or more, the sliding roof ECU activates the sliding roof motor to open the sliding roof while the key is turned.

    • When the key is not in the vehicle, the driver side door is locked, and the driver door key cylinder is turned and held in the lock direction for 1.5 seconds or more, the sliding roof ECU activates the sliding roof motor to close the sliding roof while the key is turned.

    Tech Tips

    This function is linked with the power window key-linked function.
    Wireless transmitter-linked open

    When the main body ECU (multiplex network body ECU) receives an unlock signal from the electrical key transmitter continuously for longer than 2.5 seconds, the sliding roof ECU controls the sliding roof motor in accordance with the signal to open the sliding roof.

    Tech Tips

    This function is linked with the power window wireless transmitter-linked function.
    Sliding roof open warning When the engine switch is turned from on (IG) to off and the driver door is opened with the sliding roof open, the buzzer in the combination meter assembly sounds once. Then, the warning message appears on the multi-information display.
