The direction of the air flow can be adjusted by
*Aopening,*Bclosing or*Cadjusting.The sensors*Aand*Bon the instrument
panel help maintain a constant temperature. Do
not put anything on or around these sensors.
The air conditioning system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner heats,
defogs, and ventilates efficiently, replace the
filter in accordance with the maintenance
schedule in the NISSAN Service and Mainte-
nance Guide. To replace the filter, contact a
NISSAN dealer or GT-R certified NISSAN
dealer.
The filter should be replaced if air flow is
extremely decreased or when windows fog
up easily when operating heater or air
conditioning system.

XM NavTraffic®information is a subscription
service offered by XM®Satellite Radio.
This service provides real-time information
regarding traffic flow, accidents, road construc-
tion and other incidents, where available.
XM NavTraffic
®combines information from
commercial and public traffic data providers
including government departments of transpor-
tation, police, emergency services, road sen-
sors, cameras 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 road-
ways are shown on the navigation system:
* Unscheduled traffic data for example, acci-
dents and disabled vehicles.
* Scheduled traffic data, for example road
construction 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.
NOTICE
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:

11-2General system information
DISPLAY OF CURRENT VEHICLE
LOCATION
This navigation system combines the data
obtained 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
guidance 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
position 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 satel-
lites
The reception of GPS signals can be weak,
depending on the environment. Vehicles in the
following areas/environments may not receive
GPS signals (indicator color: gray) .
*Inside tunnels or parking garages
*Areas with numerous tall buildings
*Under multi-layered highways
*Under many large trees

and follow all traffic regulations.
. Due to the coverage and quality of traffic
information and road conditions, it is not
always possible for the system to provide
the shortest time route even when traffic
information is considered. .
Traffic information that is displayed may
differ from information from other media

is not provided for some cities. In addition,
the cities for which the weather information
service is provided may be changed.
. In some cases, infrastructure problems may
prevent the complete display of the weather

SymptomPossible cause Possible solution
The location of the vehicle icon is
misaligned from the actual position. When using tire chains or replacing the tires, speed calculations 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 auto-
matically correct the vehicle icon position.
If this does not correct the vehicle icon position,
contact your NISSAN dealer or GT-R certified
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.
