XEnergy monitor
The energy monitor can be used to check the vehicle drive status,
hybrid system operation status and energy regeneration status.
While charging from the external power source, the flow of electrical
energy while charging is displayed.
On vehicles with solar charging system, the approximate power genera-
tion level is also displayed.
When energy is flowing, an arrow appears and a bright point of light
moves to show the direction of the flow of energy. When energy is
not flowing, the bright point of light is not displayed.
OThe arrows from the image of the engine to that of the electric
motor (traction motor) or tires are displayed in red.
OThe arrow indicating energy consumption is displayed in yellow,
and the arrow indicating energy regeneration or charging is dis-
played in green. Also, the color around the image of the hybrid
battery (traction battery) is changed.
As an example, all arrows are shown in the illustration, but the actual
contents of the display will differ.

XHybrid System Indicator
The display changes according to accelerator pedal operation and
displays the current driving status and energy regeneration status.
The display contents of the Hybrid System Indicator are different in EV
mode and HV mode.
The Hybrid System Indicator can be displayed on the sub-screen of the
main display (P. 217) and the head-up display (if equipped)
(P. 255).
Q
How to read the display
In EV mode
Charge area
Shows that energy is being recovered via the regenerative charging.
EV driving area
Shows that the vehicle is driven using only the electric motor (traction
motor).
Gasoline engine running area
Shows that the gasoline engine is used as auxiliary power.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
Changed within the “ECO Accelerator Guidance” range. (P. 229)

*1
Power area
Shows that an Eco-friendly driving range is being exceeded (during full
power driving etc.)
Hybrid Eco area*2
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various
conditions.
EV indicator*1, 3
The EV indicator comes on when the vehicle is driven using only the
electric motor (traction motor) or the gasoline engine is stopped.

Prius Plug-in Hybrid_OM_OM47E75E_(EE)QDisplay of the remaining hybrid battery (traction battery)
OThe current amount of the remaining hybrid battery (traction battery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
(P. 217)
• The remaining battery for EV driving in EV mode is displayed in green,
and the remaining battery used in HV mode is displayed in blue.
• The amount of the remaining battery displayed decrease as the vehicle is
driven and increase when the hybrid battery (traction battery) is charged,
electrical energy is regenerated using the regenerative braking (P. 93)
or electricity is generated by the gasoline engine.
• If the remaining battery is not displayed in green, HV mode is automati-
cally selected and EV mode cannot be used. To enable EV driving,
charge the hybrid battery (traction battery). (P. 111)
OThe amount of the hybrid battery (traction battery) in HV mode is automati-
cally controlled by the hybrid system. The amount of remaining hybrid battery
(traction battery) in HV mode may not reach the top line
* even if electrical
energy is regenerated using the regenerative braking (P. 93) or electricity
is generated by the gasoline engine. However, this does not indicate a mal-
function. Also, even if the display of the remaining hybrid battery (traction
battery) exceeds the top line, the display is shown in blue until the vehicle
returns to EV mode.
*: The position of the boundary line between EV mode and HV mode on the
display of the remaining hybrid battery (traction battery).
ODepending on the charging situation, when the display of the remaining
hybrid battery (traction battery) is shown during charging, charging continues
even after the display of the remaining hybrid battery (traction battery) shows
a fully charged state. However, this does not indicate a malfunction. Please
wait until charging is finished.The hybrid battery (traction battery)
is fully charged
The hybrid battery (traction battery)
for EV mode is not remaining

Prius Plug-in Hybrid_OM_OM47E75E_(EE)QRemaining charge amount warning of hybrid battery (traction battery)
OThe buzzer sounds intermittently when the hybrid battery (traction battery)
remains without charging while the shift position is in N, or the remaining
charge amount drops below a certain level.
If the remaining charge amount drops further, the buzzer sounds continu-
ously.
OWhen a warning message is shown on the multi-information display and the
buzzer sounds, follow the instructions displayed on the screen to perform
troubleshooting.
QAbout the Eco score
OAfter starting off, Eco score display does not start until the vehicle speed
exceeds approximately 30 km/h (19 mph).
OIn addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (P. 244). The score displayed when
the hybrid system stops is the total result of the driving status after the
hybrid system starts and the air conditioning usage condition.
Q“EV Energy” and “EV Distance” display
The rate at which the “EV Energy” and “EV Distance” remaining amount
decreases depends on the driving conditions of the vehicle. Also, the “EV
Energy” and “EV Distance” remaining amount may decrease due to system
power consumption even though the vehicle is not being driven.
