Key Off Power Window Operation
WARNING: This page is about a different car, the 2003 Lexus IS 300 and 2002 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.
After the ignition turned off, the driver's side power window can be operated for approximately 45 seconds, unless the driver's side door is opened. However, if the key off operation time finishes during AUTO operation, the AUTO operation is stopped immediately.
