◆Energy 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.
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.
● The arrows from the image of the engine to that of the electric
motor (traction motor) or ti res are displayed in red.
● The 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 th e actual
contents of the display will differ.

◆Hybrid System Indicator
The display changes according to accelerator pedal operation and
displays the current driving st atus and energy regeneration sta tus.
The display contents of the Hybrid System Indicator are differe nt in EV
mode and HV mode.
The Hybrid System Indicator can be displayed on the sub-screen of the
main display ( P. 210) and the head-up display (if equipped)
( P. 247).

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 manne r.
Changed within the “ECO Accelerator Guidance” range. ( P. 221)

*2: The EV indicator function can be turned off in the “Meter Cust omize”
settings. ( P. 241)
*3: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical e nergy.

■When operation of each function stops
● The Hybrid System Indicator stops operating in the following si tuations.
• The “READY” indicator is not illuminated.
• The shift position is not D or B.
● The Eco score and “ECO Accelerator Guidance” stop operating in the fol-
lowing situations.
• The Hybrid System Indicator is not operating.
• Dynamic radar cruise control with full-speed range is being us ed.
■ Display of the remaining hyb rid battery (traction battery)
● The current amount of the remaining hybrid battery (traction ba ttery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
( P. 210)
• The remaining battery for EV driving in EV mode is displayed i n 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. 92)
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. 108)
● The 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. 92) or electricity
is generated by the gasoline engine. However, this does not ind icate a mal-
function. Also, even if the display of the remaining hybrid bat tery (traction
battery) exceeds the top line, the display is shown in blue unt il 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).
● Depending on the charging situation, when the display of the re maining
hybrid battery (traction battery) is shown during charging, cha rging contin-
ues even after the display of the remaining hybrid battery (tra ction 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

moves to show the direction of the flow of energy. When energy is
not flowing, the bright poin t of light are not displayed.
● The display when the engine is operating is in blue while the
engine is being warmed up and yellow afterwards.
● The arrow from the engine to the motor and tires is displayed i n
red.
● The arrow indicating energy consumption is displayed in yellow
and the arrow indicating energy regeneration or charging is dis -
played in green. Also, the hybrid battery (traction battery)
changes color accordingly.
● There is an icon , , on the lower side of the
screen. The screen switches to each point of view when you
select it.
● When you select , this screen is displayed in the lower half of
