Operating Windows & Moon Roof
WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
The windows and moon roof can be opened using a wireless key from outside the vehicle (the windows can be set inoperative and the moon roof can be set to slide open, tilt up or inoperative). Push the UNLOCK button until the windows and moon roof start to move. A beep sounds just before opening. When you release the button, the windows and moon roof stop opening.
