The driver's door has a switch for the passenger and

work when the ignition has been turned to ACCESSORY
or RUN or when Retained Accessory Power (RAP) is
active. See Ignition Positions on page 2-20.
Press the switch to lower the window.
Pull up the front edge of the switch to raise the window.

Express-Down Windows

The driver and front passenger windows have an
express down feature that allows the windows to be
lowered without holding the switch. Press down fully
on the window switch, then release, to activate the
express down mode. The express down mode can be
canceled at any time by pulling up on the switch.
To open the window partway, press the switch to the
first depression position until the window is at the
desired position.
