Power Windows Press down the top of the switch to lower the window and pull up on the switch to raise the window. If you hold the switch down for three to seven seconds after the window has been completely lowered or raised, the window will not operate for about 15 seconds. Express-Down Window AUTO (Express-down): The driver's and front passenger's window switches have an express-down feature that allows you to lower the window without holding the switch down. Press down briefly on the driver's or front passenger's window switch labeled AUTO to activate the express-down feature. Lightly tap the switch to open the window slightly. The express-down feature can be interrupted at any time by pressing the top of the switch. The controls for the power windows are located on the armrest on each of the side doors. With power windows, the switches operate the windows when the ignition is in RUN, ACCESSORY or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 114. The driver's door also has a switch for each of the passenger's windows. 108
