Care of Your Compact Discs Handle discs carefully. Store them in their original cases or otherprotective cases and away from direct sunlight and dust. If the surface of a disc is soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from thecenter to the edge. Backglass Antenna (If Equipped) Your AM-FM antenna is now integrated with your rear window defogger, into your rear window. Be sure that the inside surface of the rear window is not scratched and that the lines on the glass are not damaged. If the inside surface is damaged, it could interfere with radio reception. Because this antenna is built into your rear window, there is a reduced risk of damage caused by car washes and vandals. If you choose to add a cellular telephone to your Pontiac, and the antenna needs to be attached to the glass, be sure that you do not darnage the grid lines for the AM-FM antenna. There is enough space between the lines to attach a cellular telephone antenna without interfering with radio reception. Be sure never to touch the signal surface when handling discs. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge. Fixed Mast Antenna The fixed mast antenna can withstand most car washes without being damaged. If the mast should ever become slightly bent, you can straighten it out by hand. If the mast is badly bent, as itmight be by vandals, you should replace it. Check every once in a while to be sure the mast is still tightened to the rear quarter panel. 3-32
