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.
Diversity Antenna System (If Equipped)
Your AM-FM antennas are located in the front
windshield and rear window. Be sure that the inside
surfaces of the front windshield and rear window are
not scratched and that the lines on the glass are not
damaged. If the inside surfaces are damaged, they
could interfere with radio reception. Also, for proper
radio reception, the antenna connectors at the top
-center
of the front and rear windows need to be properly
attached to the posts on the glass.
Do not apply aftermarket glass tinting. The metallic film
in some tinting materials will interfere with or distort the
incoming radio reception.
NOTICE:
Do not try to clear frost or other material from
the inside of the rear window with a razor blade
or anything else that is sharp. This may damage
the rear defogger grid and affect your radio’s
ability to pick up stations clearly. The repairs
wouldn’t be covered by your warranty.
If, when you turn on your rear window defogger, you
hear static on your radio station, it could mean that a
defogger grid line has been damaged. If this is true,
the grid line must be repaired.
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.
