(single station) FM having slightly more
range than stereo FM. External influences
may sometimes interfere with FM station
reception even if the FM station is within 25
miles (40 km). The strength of the FM signal
is directly related to the distance between
the transmitter and receiver. FM signals
follow a line-of-sight path, exhibiting many
of the same characteristics as light. For
example they will reflect off objects.
Fade and drift: As your vehicle moves away
from a station transmitter, the signals will
tend to fade and/or drift.
Static and flutter: During signal interference
from buildings, large hills or due to antenna
position, usually in conjunction with in-
creased distance from the station transmit-
ter, static or flutter can be heard. This can be
reduced by lowering the treble setting to
reduce the treble response.
Multipath reception: Because of the reflec-
tive characteristics of FM signals, direct and
reflected signals reach the receiver at the
same time. The signals may cancel each
other, resulting in momentary flutter or loss
of sound.AM radio reception
AM signals, because of their low frequency,
can bend around objects and skip along the
ground. In addition, the signals can bounce
off the ionosphere and be bent back to
earth. Because of these characteristics, AM
signals are also subject to interference as
they travel from transmitter to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas
with many tall buildings. It can also occur for
several seconds during ionospheric turbu-
lence even in areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.
HD RadioTMTechnology reception
(for U.S.)
HD RadioTMTechnology reception needs to
be activated to receive HD Radio broad-
casts.
“Audio settings” (page 3-40)
This enables you to receive radio broadcasts
digitally (where available), providing a better
quality sound with clear reception. When
this feature is not activated or HD Radio
broadcasts are not available, you will receive analog radio (AM/FM) broadcasts.
Satellite radio reception
When the satellite radio is used for the first
time or the vehicle battery (12V battery) has
been replaced, the satellite radio may not
work properly. This is not a malfunction.
Wait more than 10 minutes with the satellite
radio ON and the vehicle outside of any
metal or large building for the satellite radio
to receive all of the necessary data.
The satellite radio mode requires an active
SiriusXM Satellite Radio subscription. The
satellite service is available only to those at
least 18 and older in the 48 contiguous
United States and DC.
The satellite radio performance may be
affected if cargo carried on the roof blocks
the satellite radio signal.
If possible, do not put cargo near the
satellite antenna.
A buildup of ice on the satellite radio
antenna can affect satellite radio perfor-
mance. Remove the ice to restore satellite
radio reception.
