Swing-Out Windows Your vehicle may have swing-out windows. To open a rear swing-out window, flip the latch open and swing the glass out. Sliding Rear Window If your vehicle has this feature, squeeze the latch in the center of the window and slide the glass to open it. When you close the window, be sure the latch is engaged. The sliding rear window does not have rear defogger. However, if your vehicle has outside heated mirrors, it will have a defogger button. See Outside Heated Mirrors on page 2-64. Sun Visors To block out glare, you can swing down the visors. You can also swing them out to help block glare at the front and side windows. The passenger's side sun visor may have a vanity mirror. The latch will catch when the window is fully open and it will also hold it in the open position. 2-18
