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
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 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.
