Express Window Operation
Windows with an express-up or down feature allow the front windows to be lowered or raised without holding the switch. Rear windows only have express-down. Pull a window switch up or push it down all the way, release it, and the window goes up or down automatically. Stop the window by pushing or pulling the switch.
