This navigation system calculates the current 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) developed and operated by the U.S. Department
of Defense provides an accurate current vehicle position, normally using 4 or more satel-
lites, and in some cases 3 satellites. The GPS system has a certain level of i\
naccuracy.
While the navigation system will compensate for this most of the time, occasional \
posi-
tioning errors of up to 300 feet (100 m) can and should be expected. Generally , position
errors 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 obstructed, leading to inaccurate vehicle \
position on
the map display. Tunnels, tall buildings, 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 mad\
e
to them.
Even when the navigation system is receiving clear GPS signals, the vehi\
cle position
may not be shown accurately or inappropriate route guidance may occur in so\
me 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 of the antenna in the instrument panel. We advise against the use of win-
dow tinting on vehicles equipped with navigation systems.
(a) Accurate current vehicle position may not be shown in the following case\
s:
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 specificati\
ons.
When the tire pressure in any of the four tires is not correct.
INFORMATION
If your vehicle cannot receive GPS signals, you can correct the current po\
sition
manually. For information on setting the current position calibration, see page
108.
(b) Inappropriate route guidance may occur 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 guidanc\
e.

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 reroute during high speed driving.\
In auto re-
route, 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 m\
ore.
Some routes may not be searched.
If the route to your destination includes gravel, unpaved roads or alley\
s, the route
guidance may not be shown.
Your destination point might be shown on the opposite side of the street.\
When a portion of the route has regulations prohibiting the entry of the\
vehicle that
vary by time or season or other reasons.
The road and map data stored in your navigation system may not be complete or may
not be the latest version.
After replacing a tire, implement the operation described in the “TIR\
E CHANGE
CALIBRATION”. (See page 109.)
This navigation system uses tire turning data and is designed to work with fa\
ctory −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.
This system uses the maps of DENSO.
