Power Windows (If Equipped) If you have power windows, the controls are located on each of the side doors. Press the rear of the switch with the power window symbol on it to lower the window or the front of the switch to raise it. The driver's window also has an express down feature that allows the window to be lowered without holding the switch. Press and hold the rear of the window switch for one second to activate the express down mode. The express down mode can be canceled at any time by pressing the opposite side of the switch. To open the window partway, lightly tap the switch until the window is at the desired position. If you have power windows, the driver's door power window switch has a lockout feature. This feature prevents the rear windows from operating except from the driver's position when the front driver's door button labeled WINDOW LOCK is engaged. When the button is not engaged, the rear power windows will operate. The driver's door has a switch for the passenger's windows as well. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is present. See "Retained Accessory Power" in the Index. 2-3
