[Information Screen]
This screen indicates the direction of energy trans-
mission. It is also possible to check the current drive
method (engine, motor or both) and status of power
generation by the engine and that of charging regen-
erative energy.
This screen indicates the average fuel consumption,
amount of recovered energy and fuel consumption for
that moment. Average fuel consumption is displayed
at 5-minutes intervals. The recovered energy display
indicates the amount of energy recovered over the past
5 minutes, with each mark representing 50Wh.

A range of features for comfort - the more you use them,
the better they get.
Multi-Information Display

The 5.8º wide touch panel type multi-information color LCD
is standard.

Energy monitor, fuel consumption and other vehicle information
screens, audio operation status and audio operation screen can
be indicated on the multi-information display. The outside tem-
perature are also indicated on the screen.
[Audio system]

An AM/FM cassette and 4-speaker system compatible with the
multi-information display has been adopted.

As the touch panel type display is used to operate the audio sys-
tem, the multi-information display simultaneously indicates the
operating status of the audio system.

The antenna provided is a collapsible style pole antenna posi-
tioned at the center of the roof.
[GPS Voice Navigation]

A GPS (Global Positioning System) voice navigation system
is optional.

The multi-information display can show the map on favorite
type among turn list, arrow display and enlarged intersection.

Using DVD (Digital Versatile Disk) as a memory source for map
data, a large quantity of information can be processed.

ACCESSORIES
MULTI-INFORMATION DISPLAY
1. General
A multi-information display has been provided on top of the center console as standard equipment.
Consisting of a 5.8-inch wide LCD (Liquid Crystal Display) screen, this multi-information display pro-
vides a vehicle information screen, warning screen, and an audio operation screen. The outside tempera-
ture is also shown on the screen.
A GPS (Global Positioning System) voice navigation is offered as an option. Through the use of the GPS
and the map data in a DVD (Digital Versatile Disc), this navigation system analyzes the position of the
vehicle and indicates that position on the map that is displayed on the screen. Additionally, it provides
voice instructions to guide the driver through the route to reach the destination that has been selected.
Listed below are the main functions of the multi-information display.

4. Construction and Operation
General
This system mainly consists of a multi-information display, navigation ECU, display ECU, gateway ECU,
GPS antenna and audio unit.
The navigation ECU, display ECU, gateway ECU, and the audio unit all maintain communication through
the AVC-LAN.
Navigation ECU
The navigation ECU is provided on the models with the GPS voice navigation. Based on the map data on
the DVD, signals from the GPS satellites, signals from the built-in gyro sensor, and signals from the ve-
hicle's speed sensor, this ECU calculates the vehicle's present position, direction of travel, and driven dis-
tance, and transmits the data to the display ECU. In addition, it outputs navigation voice instructions.
Display ECU
Upon receiving the vehicle information that is transmitted by the gateway ECU, the navigation information
that is transmitted by the navigation ECU, and the operation information from the audio unit, the display
ECU displays these data on the multi-information display.
Gateway ECU
The gateway ECU transmits the vehicle information to the display ECU in order for it to be displayed on
multi-information display. Because vehicle information is transmitted by the ECUs that maintain commu-
nication on the BEAN (Body Electronics Area Network), the gateway ECU converts this information into
signals for AVC-LAN use and sends it to the display ECU.
GPS Antenna
The GPS antenna is provided on the models with the GPS voice navigation.
The GPS antenna receives signals from the GPS satellites that are located on the orbits that circle the earth
at an approximate altitude of 20,000 km. The GPS satellites continuously transmit orbit signals and the sig-
nal transmission time.
Multi-information Display
The multi-information display has the functions for displaying the map screen, audio screen, information
screen, adjustment screen, interrupt screen, and on-screen.
This system's self-diagnosis function can be displayed and operated on the multi-information display.
For details, refer to the 2001 Prius Repair Manual (Pub. No. RM778U).

1) Map Screen
The map screen is a function that is provided in the GPS voice navigation system.
Based on the map data on the DVD, signals from the GPS satellites, signals from the built-in gyro sensor,
and signals from the vehicle's speed sensor, the vehicle's present position, direction of travel, and driven
distance are calculated and displayed on this screen. This screen has the display functions listed below.
