For 1990-2009 cars only

The AM-FM antenna is located in the passenger rear side windows. Make sure the inside surfaces of the rear side windows 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.

Notice: Using a razor blade or sharp object to clear the inside of the rear side windows may affect radio reception or damage the rear side window antenna. Repairs would not be covered by the warranty. Do not clear the inside of the rear side windows 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 the antenna due to metallic tinting materials will not be covered by the warranty.

Because this antenna is built into the rear side windows, there is a reduced risk of damage caused by car washes and vandals.

If an aftermarket cellular telephone is added to the vehicle, and the antenna needs to be attached to the glass, make sure the grid lines for the AM-FM antennas are not damaged or the cellular telephone antenna is not placed over the grid lines.
