This manual explains the operation of the system. Please read this manual carefully to
ensure proper use. Keep this manual in your vehicle at all times.
The screen shots in this document and the actual screens of the system differ depend-
ing on whether the functions and/or a contract existed and the map data available at
the time of producing this document.
Please be aware that the content of this manual may be different from the system in
some cases, such as when the system’s software is updated.
The Navigation System is one of the most technologically advanced vehicle accesso-
ries ever developed. The system receives satellite signals from the Global Positioning
System (GPS) operated by the U.S. Department of Defense. Using these signals and
other vehicle sensors, the system indicates your present position and assists in locating
a desired destination.
The navigation system is designed to select efficient routes from your present starting
location to your destination. The system is also designed to direct you to a destination
that is unfamiliar to you in an efficient manner. Map database is made based on AISIN
AW maps, whose information source comes from NAVTEQ maps. The calculated
routes may not be the shortest nor the least traffic congested. Your own personal local
knowledge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes Point of Interest categories to allow you to
easily select destinations such as restaurants and hotels. If a destination is not in the da-
tabase, you can enter the street address or a major intersection close to it and the sys-
tem will guide you there.
The system will provide both a visual map and audio instructions. The audio instructions
will announce the distance remaining and the direction to turn when approaching an
intersection. These voice instructions will help you keep your eyes on the road and are
timed to provide enough time to allow you to maneuver, change lanes or slow down.
Please be aware that all current vehicle navigation systems have certain limitations that
may affect their ability to perform properly. The accuracy of the vehicle’s position de-
pends on satellite conditions, road configuration, vehicle condition or other circum-
stances. For more information on the limitations of the system, refer to page 184.

• 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 a parking lot.
• When leaving a covered parking lot or
parking garage.
• When a roof carrier is installed.
• When driving with tyre chains installed.
• When the tyres are worn.
• After replacing a tyre or tyres.
• When using tyres that are smaller or
larger than the factory specifications.
• When the tyre pressure in any of the 4
tyres is not correct.zInappropriate route guidance may occur in
the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than 1 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.
• During high speed driving, it may take a
long time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be
changed.
• If an unnecessary U-turn is shown or
announced.
• If a location has multiple names and the
system announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes
gravel, unpaved roads or alleys, the route
guidance may not be shown.
zIf the vehicle cannot receive GPS signals,
the current position can be adjusted
manually. (→P.1 7 3 )
