To open your manual windows, turn the hand crank on
each door to raise or lower your side door windows.
Power Windows (Option)
If you have the optional power windows, the controls
are on each of the front side doors. The driver’s door has
a switch for the front passenger window as well. Your
power windows will not move unless the ignition has
been turned to RUN or ACCESSORY, or retained
accessory power is present. See “Retained Accessory
Power” in the Index.
Express-Down Window
The driver’s window switch also has an express

window switch. Press and hold the side of the driver’s
window switch down marked AUTO for one second to
activate the express-down feature. The express-down
feature can be interrupted at any time by pressing the up
arrow end of the switch. Lightly tap the switch to open
the window slightly.
