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.
Rear Side Window
Antenna
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.
If a cellular telephone antenna
needs to be attached to the glass,
make sure that the grid lines for the
AM-FM antenna are not damaged.
There is enough space between
the grid lines to attach a cellular
telephone antenna without
interfering 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.
Satellite Radio Antenna
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
(if equipped) may be affected if the
sunroof is open.
