Express Down
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The driver and passenger windows have an express down feature. This feature allows the door modules to activate the driver or passenger window down without holding the window down switch for the entire duration. To activate this feature, momentarily press either window switch for one-third of a second and release. The door modules will lower the selected window completely down. The express down feature can be discontinued at any time by pressing the window switch again.
