XM™ Satellite Radio Antenna System The 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. If your vehicle has a sunroof, the performance of the XM™ system may be affected if the sunroof is open. If the rear roof rack rail is too close to the XM™ antenna or if objects stored on the roof rack cover or block the XM™ antenna, the performance of the XM™ system may be affected. Chime Level Adjustment Chime level adjustment is only available on RDS radios. The radio is used to adjust the vehicle's chime level. To change the volume level of the chime, press and hold pushbutton 6 with the ignition on and the radio power off. The volume level will change from the normal level to loud, and LOUD will appear on the radio display. To change back to the default or normal setting, press and hold pushbutton 6 again. The volume level will change from the loud level to normal, and NORMAL will appear on the radio 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. 3-84
