Foreword
Thank you for your purchase of the Navigation System. Please read this manual carefully to ensure proper use. Keep this
manual stored in your vehicle at all times.
The Toyota Navigation System is one of the most technologically advanced vehicle accessories ever developed. The system receives
satellite si gnals from the Global Positioning System (GPS) operated by the U. S. Department of Defense. Using these signals and other
vehicle sensors, the system can show you where you are and assist you in locating a desired destination.
The navigation system is designed to select efficient routes from your present starting location to your destination. The syste m is
designed to direct you to a destination that is unfamiliar to you in an efficient manner. Map database is made based on the map s, 2001
edition of DENSO, whose information source comes from NavTech maps and GDT maps. The calculated routes are neither the shortest
routes nor routes without traffic congestion. Your own personal local knowledge or “short cut” may at times be faster than the
calculated routes.
The navigation system’s database includes about 50 point of interest categories to allow you to easily select destinations such as
restaurants and hotels. If a destination is not in the database, you can enter the street address or a major intersection close to it and
the system will route you there. The system will provide both a visual map and audio instructions. The audio instructions will announce
the distance and direction to go when you are approaching a fork or intersection. These voice instructions will help you keep y our 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 ab ility to perform
properly. The accuracy of the vehicle’s position depends on the satellite c ondition, road configuration, vehicle condition or
other circumstances. For more information on the limitations of the system, refer to pages 49 through 51.

3. When there are 2 map screens dis-played to switch the “North
up”/“Headingup” of the right screen
map, select
“Right screen”
switch.
4. Select the “Map orient” of the
“Edit right screen”, and then the
“Northup”/“Headingup” of the right
screen is switched.
When 2 map screens are displayed, you
can set one as the “North −up” and the
other one as the “Heading −up.” This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate position
may not be shown depending on the
satellite condition, road configuration,
vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position using 3 to 4
satellites. The GPS system has a certain
level of inaccuracy built in for security
reasons. While the navigation system will
compensate for this most of the time, oc-
casional positioning errors up to 300 feet
can and should be expected. Generally,
position errors will be corrected within a
few seconds.

When your vehicle is not receiving signals
from the satellites, the “GPS” mark does
not appear at the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The installation of window tinting may also
obstruct the GPS signals. Most window
tinting contains some metallic content that
will interfere with the GPS signal recep-
tion. We recommend not to use the win-
dow tinting on vehicles equipped with nav-
igation systems.The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving good GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
When driving on a small angled Y
−
shaped road.
When driving on a spiral road.
When driving on a slippery road such
as in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway 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 directions
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 the tire chains
installed.
When the tires are worn.
After replacing a tire or tires.
(a) Accurate current vehicle
position may not be shown in
the following cases:

After you input that information, select the
“OK” switch. The screen then returns to
the “Maintenance” screen. The icon’s color
will change to green after the date or driv-
ing distance is inputted. The icon’s color
will change to orange when your Toyota
needs to be serviced. The following
switches appear on the screen.
“Delete all”: Cancel all conditions which
have been inputted.
“Reset all”: Reset all items which satisfy
either condition.
Select the
“Off” switch at the top of the
“Maintenance” screen, and the information
screen will no longer be displayed.
INFORMATION
 For scheduled maintenance informa-
tion, please refer to the “Owner ’s
Manual Supplement” or “Scheduled
Maintenance”.
 Depending on your driving or the
road conditions, the system may
have a timelag between the data
which has been inputted and the ac-
tual date and driving distance.
