    Key-linked open and close*2, *3

    • When the key is not in the vehicle, the driver door is unlocked, and the driver door key cylinder is turned and held in the unlock direction for 2.5 seconds or more, the sliding roof ECU (sliding roof drive gear sub-assembly) 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 door is locked, and the driver door key cylinder is turned and held in the lock direction for 2.5 seconds or more, the sliding roof ECU (sliding roof drive gear sub-assembly) 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*2, *3

    • When the main body ECU (multiplex network body ECU) receives an unlock signal from the transmitter continuously for longer than 4 seconds, the sliding roof ECU (sliding roof drive gear sub-assembly) activates the sliding roof motor to open the sliding roof while the transmitter switch pressed.
