Limitations of the
navigation system
This navigation system calculates the cur-
rent vehicle position using satellite sig-
nals, various vehicle signals, map data,
etc. However, the accurate position may
not be shown depending on the satellite
condition, road configuration, vehicle
condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department of
Defense provides an accurate current vehicle
position using 3 to 4 satellites. The GPS sys-
tem has a certain level of inaccuracy. While
the navigation system will compensate for
this most of the time, occasional positioning
errors of up to 300 feet (100 m) can and
should be expected. Generally, position er-
rors will be corrected within a few seconds.
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct the
GPS signals.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiving
clear GPS signals, the vehicle position may
not be shown accurately or inappropriate
route guidance may occur in some cases.
NOTICE
The installation of window tinting may
obstruct the GPS signals. Most window
tinting contains some metallic content
that will interfere with GPS signal recep-
tion. We advise against the use of win-
dow tinting on vehicles equipped with
navigation systems.

109 (a) Accurate current vehicle position
may not be shown in the following cases:
When driving on a small angled Y−shaped
road.
When driving on a winding road.
When driving on a slippery road such as
in sand, gravel, snow, etc.
When driving on a long straight road.
When motorway and surface streets run
in parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during high
speed driving.
When driving without setting the current
position calibration correctly.
After repeating a change of direction by
going forward and backward, or turning on
a turntable in the parking lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with tire chains installed.
When the tires are worn.
After replacing a tire or tires.
When using tires that are smaller or larger
than the factory specifications.
When the tire pressure in any of the four
tires is not correct.
INFORMATION
If your vehicle cannot receive GPS sig-
nals, you can correct the current posi-
tion manually. For information on set-
ting the current position calibration, see
page 88.
(b) Inappropriate route guidance may oc-
cur in the following cases:
When turning at an intersection off the
designated route guidance.
If you set more than one destination but
skip any of them, auto reroute will display
a route returning to the destination on the
previous route.
When turning at an intersection for which
there is no route guidance.
When passing through an intersection for
which there is no route guidance.
During auto reroute, the route guidance
may not be available for the next turn to
the right or left.
It may take a long time to operate auto re-
route during high speed driving. In auto
reroute, a detour route may be shown.
After auto reroute, the route may not be
changed.
An unnecessary U−turn may be shown or
announced.
A location may have multiple names and
the system will announce one or more.
Some routes may not be searched.
If the route to your destination includes
gravel, unpaved roads or alleys, the route
guidance may not be shown.
Your destination point might be shown on
the opposite side of the street.

11 0
When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other rea-
sons.
The road and map data stored in your nav-
igation system may not be complete or
may not be the latest version.
After replacing a tire, implement the op-
eration described in the “TIRE CHANGE
CALIBRATION”. (See page 89.)
This navigation system uses tire turning data
and is designed to work with factory−speci-
fied tires for your vehicle. Installing tires that
are larger or smaller than the originally
equipped diameter may cause inaccurate
display of the vehicle’s position. The tire pres-
sure also affects the diameter of the tires so
please make sure the tire pressure of all four
tires is correct.

The marks of companies displayed by
this product to indicate business loca-
tions are the marks of their respective
owners. The use of such marks in this
product does not imply any sponsorship,
approval, or endorsement by such com-
panies of this product.There are two types of areas available for
route guidance. In one type of area, pri-
marily around metropolitan centers, de-
tailed route guidance is available for the
entire area. In the other type of area, all
roads are displayed on the map but route
guidance is limited. The navigation route
might lack precision because the data (no
right turns, oneway traffic, etc.) is not
complete. It is still possible to reach the
destination by following the arrow direc-
tion and distance as shown on the bottom
left of the screen. The arrow points in the
direction of the destination. The distance
shown is as measured in a straight line
from the current vehicle position to the
destination area.
In order to provide you with as accurate map
information as possible, we are always gath-
ering information such as on road repairs and
carrying out on−site investigations. However,
the names of roads, streets, facilities, and
their locations frequently change. In some
places, construction on roads may be in pro-
gress. For that reason, information on some
areas in this system might be different from
the actual location.
The map database is normally updated once
a year. Contact your dealer for information
about the availability and pricing of an update.
