The sliding roof has the following features:

Function
Outline
Manual slide open and close
This function causes sliding roof to open (or close) when OPEN/CLOSE switch is pressed for a maximum of 0.3 seconds. Sliding roof stops as soon as the switch is released.
Auto slide open and close
This function causes sliding roof to fully open (or close) when OPEN/CLOSE switch is pressed for a minimum of 0.3 seconds.
Manual tilt up and down
This function causes sliding roof to tilt up (or tilt down) when UP/DOWN switch is pressed for a maximum of 0.3 seconds.
Auto tilt up and down
This function enables sliding roof to tilt up (or down) when UP/DOWN switch is pressed for a minimum of 0.3 seconds.
Jam protection
The jam protection function automatically stops sliding roof, or stops sliding roof and makes it open halfway (or fully tilted up) if a foreign object gets jammed in sliding roof during auto close operation (or auto tilt down operation).
Key off operation
Key off operation function makes it possible to operate sliding roof for approximately 43 seconds after ignition switch is turned off, if front doors are not opened.
Key-linked open and close
When key is not in vehicle, driver's side door key is locked, and key inserted into driver's side door key cylinder is turned and maintained in lock position for 3 seconds or more, sliding roof control ECU activates sliding roof motor to close sliding roof while key is turned. Similarly, when driver's side door is unlocked and key in driver's side door is turned and maintained in unlock position for 3 seconds or more, sliding roof control ECU activates sliding roof motor to open sliding roof.
Transmitter-linked open and close
When main body ECU receives an unlock signal from key continuously for 3 seconds or more, sliding roof control ECU activates sliding roof motor to open sliding roof. Similarly, when main body ECU receives a lock signal from key continuously for 3 seconds or more, sliding roof control ECU activates sliding roof motor to close sliding roof.
Sliding roof open warning
When the ignition switch is changed from on (IG) to off and the driver's side door is opened when the sliding roof is open, the sliding roof control ECU sounds the buzzer in the combination meter assembly. Then, a warning message appears on the multi-information display.
