Pontiac 2005 Grand Prix - Manual (Page 241)

Notice: Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside 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.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a 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 antenna. There is enough space between
the lines to attach a cellular telephone antenna
without interfering with radio reception.
Do not apply aftermarket glass tinting to the back glass.
The metallic film in some tinting materials will interfere
with or distort the incoming radio reception. Care
must be taken when cleaning the rear window because
it breaks in the resistive material heating element
and will adversely affect radio and defogger
performance. See your dealer for details.
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.
The performance of the XM system may be affected if
the sunroof is open.
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 radio 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 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.
