XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio reception
from coast-to-coast in the 48 contiguous United States,
and in Canada. Just as with FM, tall buildings or
hills can interfere with satellite radio signals, causing the
sound to fade in and out. In addition, traveling or standing
under heavy foliage, bridges, garages, or tunnels may
cause loss of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged as long as it is securely
attached to the base. If the mast becomes slightly bent,
straighten it out by hand. If the mast is badly bent,
replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten by
hand until fully seated plus one quarter turn.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof of
the vehicle. Keep the antenna clear of obstructions for
clear radio reception.
If the vehicle has a sunroof, the performance of the
XM system may be affected if the sunroof is open.
Chime Level Adjustment
The radio may be used to adjust the vehicle’s chime
level. If the radio can be used to change the volume
level of the chime, press and hold the sixth numbered
pushbutton or the sixth FAV pushbutton with the ignition
on and the radio power off. The volume level changes
between Normal and Loud. The selected volume
level appears on the radio display.
Removing the radio and not replacing it with a factory
radio or chime module will disable vehicle chimes.
