Backglass Aerial
The AM-FM aerial is integrated with
the rear window demister in the rear
window. Do not scratch the inside
surface or damage the lines in the
glass. If the inside surface is damaged,
it could interfere with radio reception.
For proper radio reception, the aerial
connector needs to be properly
attached to the post on the glass.
If attaching a mobile phone aerial to
the glass, attach it between the grid
lines.
Caution
Using a razor blade or sharp object
to clear the inside rear window can
damage the rear window aerial and/
or the rear window defogger.
Repairs would not be covered by
the vehicle warranty. Do not clear
the inside rear window with sharp
objects.
Caution
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 backglass aerial due to metallic
tinting materials will not be covered
by the vehicle warranty.
Multi-Band Aerial
The roof aerial is for the GPS (Global
Positioning System). Keep clear of
obstructions for clear reception. If the
vehicle has a sunroof, and it is open,
reception can also be affected.
