Diversity Antenna System Your AM-FM antenna is integrated with your rear quarter glass windows, located in the rear of the vehicle on the driver and passenger sides. Be sure that the inside surface of the rear windows are not scratched and that the lines on the glass are not damaged. If the inside surface is damaged, it could interfere with radio reception. If, when you turn on your rear window defogger, you hear static on your radio station, it could mean that a defogger grid line has been damaged. If this is true, the grid line must be repaired. If you choose to add an aftermarket cellular telephone to your vehicle, and the antenna needs to be attached to the glass, be sure that you do not damage the grid lines for the AM-FM antennas or place the cellular telephone antenna over the grid lines. Notice: Do not apply aftermarket glass tinting with metallic film. The metallic film in some tinting materials will interfere with or distort the incoming radio reception. Any damage caused to your backglass antenna due to metallic tinting materials will not be covered by your warranty. Notice: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect your radio's ability to pickup stations clearly. The repairs wouldn't be covered by your warranty. XM™ Satellite Radio Antenna System (48 Contiguous US States) Your XM™ Satellite Radio antenna is located on the roof of your vehicle. Keep this antenna clear of snow and ice build up for clear radio reception. The performance of your XM™ system may be affected if your sunroof is open. Loading items onto the roof of your vehicle can interfere with the performance of your XM™ system. Make sure that the XM™ satellite antenna is not obstructed. 3-128
