are also subject to interference as
they travel from transmitter to
receiver.
Satellite Radio Reception (If
Equipped)
When the satellite radio is used for
the first time or the battery has been
replaced, the satellite radio may not
work properly. This is not a
malfunction. Wait more than
10 minutes with satellite radio on
and the vehicle outside of any metal
or large building for satellite radio to
receive all of the necessary data.
No satellite radio reception is
available and“NO SAT”is displayed
when the SAT band option is
selected unless an optional satellite
receiver and antenna are installed
and a SiriusXM Satellite Radio
service subscription is active.
Satellite radio performance may be
affected if cargo carried on the roof
blocks the satellite radio signal.
If possible, do not put cargo over
the satellite antenna. A build up of ice on the satellite
radio antenna can affect satellite
radio performance. Remove the ice
to restore satellite radio reception.
Cellular Phone Usage
Cellular phone usage can cause
interference with the vehicle's radio.
Fixed Mast Antenna
The fixed mast antenna will go
through most car washes as long as
it is securely attached. If the
antenna becomes slightly bent,
straighten it out by hand. If it is
badly bent, replace it.
Occasionally check that the antenna
is tight at the base. If tightening is
required, protect the paint from
damage.

Problems with Route
Guidance
.
The navigation system may not
calculate a route if the current
vehicle location is too far away
from the destination. In this
case, divide your trip by
selecting one or two
intermediate destinations.
. To reach the destination, refer to
the map view. Always follow
actual roads and regulations and
drive safely. .
The suggested route may not be
the shortest, nor are other
circumstances such as traffic
jams considered unless the
SiriusXM Traffic is active.
. Because of the differences in
road conditions and
circumstances between the time
you use this system and the time
the information was produced for
the map data, there may be
discrepancies in roads and
regulations. In such cases,
follow the actual information
available.
. During route calculation, the
map will not scroll, however the
vehicle icon will move with the
actual vehicle’s movement.
. In some cases, after the
calculation is complete, the
calculated route may not be
immediately displayed.
. It may take more time to finish
drawing a route if the map is
being scrolled at the same time.
