    Jam protection function The jam protection function automatically stops the sliding roof and moves it open halfway (or fully tilts it 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 ignition switch is turned off if the driver side door is not opened.
    Wireless transmitter-linked operation

    • When the main body ECU (multiplex network body ECU) receives an unlock signal from the door control transmitter continuously for 3.0 seconds or more, the sliding roof ECU controls the sliding roof motor in accordance with the signal to slide open the sliding roof.

    • When the main body ECU (multiplex network body ECU) receives a lock signal from the door control transmitter continuously for 3.0 seconds or more, the sliding roof ECU controls the sliding roof motor in accordance with the signal to slide close the sliding roof.

    • When the main body ECU (multiplex network body ECU) receives an unlock signal from the door control transmitter continuously for 3.0 seconds or more, the sliding roof ECU controls the sliding roof motor in accordance with the signal to tilt up the sliding roof.

    • When the main body ECU (multiplex network body ECU) receives a lock signal from the door control transmitter continuously for 3.0 seconds or more, the sliding roof ECU controls the sliding roof motor in accordance with the signal to tilt down the sliding roof.

    Tech Tips

    This function is linked with the power window wireless transmitter-linked operation.
    Key-linked operation

    • When the key is not in the vehicle, the driver side door is unlocked, and the key in the driver side door is turned and held in the unlock direction for 2.0 seconds or more, the sliding roof ECU activates the sliding roof motor to slide 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 key in the driver side door is turned and held in the lock direction for 2.0 seconds or more, the sliding roof ECU activates the sliding roof motor to slide close the sliding roof while the key is turned.

    • When the key is not in the vehicle, the driver side door is unlocked, and the key in the driver side door is turned and held in the unlock direction for 2.0 seconds or more, the sliding roof ECU activates the sliding roof motor to tilt up the sliding roof while the key is turned.

    • When the key is not in the vehicle, the driver side door is locked, and the key in the driver side door is turned and held in the lock direction for 2.0 seconds or more, the sliding roof ECU activates the sliding roof motor to tilt down the sliding roof while the key is turned.
