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.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.
Chime Level Adjustment
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 to indicate the new
volume selected. Removing the radio and not
replacing it with a factory radio or chime module
will disable vehicle chimes.
