Power Windows Switches located on the driver's door armrest control
each of the windows when the ignition is in ON, ACC,
or when retained accessory power (RAP) is active. In
addition, each passenger's door has a window switch.

The driver's window switch has an express down
feature. This switch is labeled AUTO. Tap the rear of
the switch, and the driver's window will open a small
amount. If the rear of the switch is fully pressed, the
window will go all the way down.
To stop the window while it is lowering, press the front
of the switch. To raise the window, press and hold the
front of the switch.

The driver's window controls also include a lock out
switch. Press LOCK to stop front and rear passengers
from using their window switches. The driver can still
control all the windows with the lock on. Press the
