information is a subscription ser-
vice offered by XM Satellite Radio.
This service provides real-time information re-
garding traffic flow, accidents, road construction
and other incidents, where available.
XM NavTraffic combines information from com-
mercial and public traffic data providers includ-
ing government departments of transportation,
police, emergency services, road sensors, cam-
eras and aircraft reports. The traffic information
is broadcast to the vehicle by the XM satellites.
Available traffic information on the route the
driver selected is shown on the navigation
screen so traffic conditions between you and the
destination are known. Three types of real-time
traffic information for major roadways are shown
on the navigation system:
● Unscheduled traffic data for example, acci-
dents and disabled vehicles.
● Scheduled traffic data, for example road con-
struction and road closures.
● Traffic flow information (rate of speed data) .
WARNING
XM NavTraffic information is not a
substitute for attentive driving. Traffic
conditions change constantly and
emergency situations can arise without
warning. Relying only on XM NavTraf-
fic information may lead to a collision
and could result in serious personal
injury.
NOTE:
Flow information is provided only for
roads equipped with traffic sensors and is
not available in all markets covered by the
service. Flow data may not be available on
portions of a road that is under
construction.
XM NavTraffic information is available in limited
markets. To subscribe or to check if this service
is available in the area:

DISPLAY OF CURRENT VEHICLE
LOCATION
This navigation system combines the data ob-
tained from the vehicle (by gyro sensor) and from
GPS (Global Positioning System) satellites to
calculate the current location of the vehicle. This
position is then displayed throughout route guid-
ance to a destination.
WHAT IS GPS (Global Positioning
System)?
GPS is a position detecting system that uses
satellites deployed by the U.S. government. This
navigation system receives radio signals from
three or more different satellites that orbit
13,049 miles (21,000 km) above the earth in
space, and detects the position of the vehicle by
utilizing the principle of triangulation.
Positioning adjustment
When the system judges that the vehicle posi-
tion information is not accurate based on vehicle
speed and gyro sensor data calculations, the
system will automatically adjust the position of
the vehicle icon using GPS signals.
Receiving signals from GPS satellites
The reception of GPS signals can be weak, de-
pending on the environment. Vehicles in the fol-
lowing areas/environments may not receive GPS
signals.

10-4General system information

●As of January 31, 2009, the XM NavTraffic
service covers 80 major metropolitan markets.
For the most current list of markets covered,
please refer to www.xmradio.com/navtraffic,
or call XM Radio customer support at
1-800-XMRADIO (1-800-967-2346) .
● Due to road maintenance, infrastructure prob-
lems (e.g. malfunction of road sensors, outage
of central computer of infrastructure) or natu-
ral disasters, there are times when some or all
traffic information may not be available.
● Incident information is based on human
collection. Not all incidents that have hap-
pened are collected and provided.
● Due to infrastructure problems, or transmis-
sion delay, there are times when the informa-
tion may differ from the actual condition. Al-
ways observe safe driving practices and
follow all traffic regulations.
● Due to the coverage and quality of traffic in-
formation and road conditions, it is not always
possible for the system to provide the short-
est time route even when traffic information is
considered.
● Traffic information that is displayed may differ
from information from other media (e.g.,
radio) , as other media may use different infor-
mation sources. ●
The XM NavWeather™ information service is
not provided for some cities. In addition, the
cities for which the weather information ser-
vice is provided may be changed.
● In some cases, infrastructure problems may
prevent the complete display of the weather
information. This is not a malfunction.
● Due to infrastructure problems, or due to the
time when the weather information service
broadcast is received, the displayed informa-
tion may differ from the actual weather
conditions.
●
XM NavWeather™ is a service of XM Satellite
Radio. XM NavWeather™ is only available in se-
lect markets within the 48 contiguous United
States and is subject to data availability. Recep-
tion of the XM signal may vary depending on
location. It requires a monthly premium
subscription. The service provider is solely re-
sponsible for the quality and accuracy of the in-
formation provided. All fees and programming
are subject to change. For more details on the

● XM NavWeather™ is designed to provide real-
time weather and forecasting information in
your general vicinity. Discrepancies may be
encountered between the system and your
actual location. Road system and weather
changes may affect the accuracy of the infor-
mation provided. Rely on your common sense
to decide whether to follow a specified route.
Detailed coverage is not available in every city
or roadway.

FORMATION
General system information10-15

SymptomPossible cause Possible solution
The GPS indicator on the screen remains gray. GPS signals cannot be received under certain conditions, such as in a parking garage, on a road with many tall
buildings, etc. Drive on an open, straight road for a while.
GPS signals cannot be received because objects are placed
on the instrument panel. Remove the objects from the instrument panel.
A sufficient number of GPS satellites is not available. Wait for the satellites to move to locations available for the navi- gation system.
The location of the vehicle icon is misaligned from
the actual position. When using tire chains or replacing the tires, speed calcula-
tions based on the speed sensor may be incorrect. Drive the vehicle for a while (at approximately 19 MPH [30 km/h]
for about 30 minutes) to automatically correct the vehicle icon
position. If this does not correct the vehicle icon position, con-
tact a NISSAN dealer.
The map data has a mistake or is incomplete (the vehicle
icon position is always misaligned in the same area) . Updated road information will be included in the next version of
the map data.
