Diversity Antenna System Your AM-FM antennas are located in the rear side windows. Be sure that the inside surfaces of the rear side windows are not scratched and that the lines on the glass are not damaged. If the inside surfaces are damaged, they could interfere with radio reception. Notice: Using a razor blade or sharp object to clear the inside of the windshield or rear window may affect radio reception or damage the rear window defogger. Repairs would not be covered by your warranty. Do not clear the inside windshield or rear window with sharp objects. 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. 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. 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. Chime Level Adjustment The radio is the vehicle chime producer. To change the volume level, press and hold pushbutton 6 with the ignition on and the radio power off. The chime volume level will change from the normal level to loud, and LOUD will appear on the display. To change back to the default or normal setting, press and hold pushbutton 6 again. The chime level will change from the loud level to normal, and NORMAL will appear on the display. Each time the chime volume is changed, three chimes will sound as an example of the new volume selected. Removing the radio and not replacing it with a factory radio or chime module will disable vehicle chimes. 3-99
