Noise is heard when using a cellular phone under/
near areas of elevated railroads, high voltage
electric power cables, traffic signals, neon bill-
boards, etc. Electromagnetic waves that are generated from radio
devices may adversely affect the cellular phone.
This is not a malfunction.
Noise is heard in the sound from the audio system
while using a cellular phone. Radio waves that are generated from a cellular phone

The fan speed of the air conditioner is too fast. Decrease the fan speed of the air conditioner.
The ambient noise level is excessive. (For example:
heavy rain, construction sites, inside a tunnel, oncoming
vehicles, etc.)Close the windows to shut out ambient noise.
The noise generated by driving the vehicle is too loud. Reduce the vehicle speed, and then speak the command.

CURRENT VEHICLE LOCATION
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
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.
When the system judges that the vehicle
position 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,
depending on the environment. Vehicles in the
following areas/environments may not receiveGPS signals (indicator color: gray) .*Inside tunnels or parking garages
*In areas with numerous tall buildings
*Under multi-layered highways
*Areas with numerous tall trees

*In a canyon
The GPS antenna is located on the instrument
panel inside the vehicle. Do not place any
objects, especially cellular phones or transcei-
vers, on the instrument panel. Because the
strength of the GPS signal is approximately one
billionth of that of TV waves, phones and
transceivers will affect or may totally disrupt

GPS information can be displayed.

Incorrect display of vehicle position
The following cases may affect the display
accuracy of the vehicle’s position or traveling
direction. The accuracy will return to normal if
the driving conditions return to normal.
*When there is a similar road nearby.
*When the vehicle is traveling in an area with a
grid pattern road system.
*When the vehicle is passing through a large Y-

. The vehicle icon may be misaligned when
starting the vehicle just after the READY to
drive indicator light is ON.
. The vehicle icon may also be misaligned if
different sized tires or tire chains are
. The system has a function that automatically
corrects the vehicle icon position when it is
misaligned from the actual position.
. Vehicle position correction by GPS may not
function when the vehicle is stopped.
. If the vehicle icon position does not return to
normal even after driving for a while, correct
the vehicle icon position manually.

Detailed Map Coverage Areas
(MCA) for navigation system
This system is designed to help guiding to the
destination, and it also performs other functions
as outlined in this manual. However, the system
must be used safely and properly. Information
concerning road conditions, traffic signs and the
availability of services may not always be up-to-
date. The system is not a substitute for safe,
proper and legal driving.
Map data covers select metropolitan areas in the
United States and Canada.
Map data includes two types of areas: “Detailed
coverage areas” providing all detailed road data
and other areas showing “Main roads only”.
Detailed map data is not available in many areas
and is generally limited to select major metro-

The navigation system does not provide
route guidance for roads displayed in dark
green. Therefore, if the destination is set on
a road displayed in dark green, the enlarged
map display will return to the ordinary map
screen at some point on a suggested route
that is near the destination. Also, voice
guidance will stop at some point on a
suggested route that is near the destination.
. Places information and street names near
roads displayed in gray may not be con-
tained in the map data.

included on a suggested route when the

. If waypoints are set, the system calculates
multiple routes between waypoints simulta-
neously, and the following may result.
— If one section between waypoints cannot
be calculated, none of the route will be
— The route may not connect completely at some waypoints.
— The route may require a U-turn close to some waypoints.
. Route calculation may not be completed in
the following cases.
— If there is no main road within a range of
1.5 miles (2.5 km) from the vehicle, a
message saying so will appear on the
screen. Try recalculating when the vehi-
cle is closer to a main road. — If there is no main road within a range of
1.5 miles (2.5 km) from the destination or

accurate. In this case, park the vehicle in
a safe location and reset the vehicle icon,
or continue driving to see if the position

of the vehicle icon is automatically
adjusted before recalculating the route.
— There are cases in which the system shows an indirect route to reach the
destination or waypoints, if you set them
from stored or facility information. In
order to correct this, you must be careful
about the traffic direction, especially
when lanes with different travel directions
are shown separately, such as inter-
changes and service areas.
— This system makes no distinction be- tween limited traffic control and total
control (blockage) . It may show an
indirect route even if the road is usable.

The system will only announce street names
when the system language is set to English.
Street names are not announced when the
system is set to Franc¸ ais (French).
Basics of voice guidance
Voice guidance announces which direction to
turn when approaching an intersection in which
a turn is necessary.
. There may be some cases in which voice
guidance and actual road conditions do not
correspond. This may occur because of
discrepancies between the actual road and
the information on the map data, or it is due
to the vehicle’s speed.
. In case voice guidance does not correspond
to the actual road conditions, follow the
information obtained from traffic signs or
notices on the road.
. Route guidance provided by the navigation
system does not take carpool lane driving
into consideration, especially when carpool
lanes are separated from other road lanes.
