sat nav TOYOTA PRIUS 2003 1.G Navigation Manual

i
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.
TheToyota Navigation System is one of the most technologically advanced vehicle ac\
cessories ever developed. The system receives satellit e
signals from the Global Positioning System (GPS) operated by the U. S. Department of Defense. Using these signals and other vehicle \
sen-
sors, the system can show you where you are and assist you in locating a desi\
red destination.
The navigation system is designed to select efficient routes from your present starting location to your destination. \
The syst em is designed
to direct you to a destination that is unfamiliar to you in an ef ficient manner. The system uses the maps of DENSO based on NA VTECH maps,
GDT maps and infoUSA POIs. 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 cal\
culated routes.
The navigation system’s database includes more than 50 points of interest categories to allow yo\
u to easily select destinations such as restau-
rants and banks. 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 instructi\
ons. The audio instructions will announce the distance and
direction to go when you are approaching a fork or intersection. These voice inst\
ructions will help you keep your eyes on the r oad 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 limitatio\
ns that may affect their ability to perform properly.
The accuracy of the vehicle’s position depends on the satellite condition, road configuration, vehicle condition or other \
circumstan-
ces. For more information on the limitations of the system, refer to pages 4\
9 through 51.

You can change the orientation of the
map from Northup to Headingup by
touching the direction symbol at the top
left of the screen.Northup symbol
Regardless of the direction of vehicle travel,
North is always up.
Headingup symbol
The direction of the vehicle travel is always
up. A red arrow indicates North. This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However,
the accurate position
may not be shown depending on the sat-
ellite condition, road configuration, ve-
hicle condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department
of Defense provides an accurate current ve-
hicle 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, occasional 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 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 installation of window tinting may also
obstruct the GPS signals. Most window tint-
ing contains some metallic content that will
interfere with the GPS signal reception. We
recommend not to use the window tinting on
vehicles equipped with navigation systems. The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiv-
ing good GPS signals, the vehicle position
may not be shown accurately or inappropri-
ate 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.
