|
Function |
Outline |
|---|---|
|
Manual slide open and close |
This function causes the sliding roof to open (or close) when the OPEN switch (or CLOSE switch) is pressed for a maximum of 0.3 seconds. The sliding roof stops as soon as the switch is released. |
|
Auto slide open and close*1, *2 |
This function causes the sliding roof to reach the comfort stop position or fully open (or fully close) when the OPEN switch (or CLOSE switch) is pressed for a minimum of 0.3 seconds. |
|
Manual tilt up and down |
This function causes the sliding roof to tilt up (or tilt down) when the UP switch (or DOWN switch ) is pressed for a maximum of 0.3 seconds. The sliding roof stops as soon as switch is released. |
|
Auto tilt up and down*1, *2 |
This function causes the sliding roof to fully tilt up (or tilt down) when the UP switch (or DOWN switch) is pressed for a minimum of 0.3 seconds. |
|
Jam protection*2 |
The jam protection function automatically stops the sliding roof and moves it open halfway (or fully tilt up) if a foreign object gets jammed in the sliding roof during close or tilt down operation. |
|
Key-off operation*2 |
The key-off operation function makes it possible to operate the sliding roof for approximately 43 seconds after the ignition switch is turned to ACC or off, if the front doors are not opened. |
|
Key-linked open and close*2, *3 |
HINT: 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. HINT: This function is linked with the power window wireless transmitter-linked function. |
|
Sliding roof open warning*1, *2 |
When the ignition switch is turned from ON to off and the driver door is opened with the sliding roof open, the buzzer in the combination meter assembly sounds once. Then, a warning message appears on the multi-information display.*4 |
