Introduction
This manual explains the operation of the Navigation 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 navigation system dif-
fer depending 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 navigation
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. The system uses DENSO maps. The cal-
culated routes may not be the shortest nor the least traffic congested. Your own per-
sonal 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 in 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 160.
