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).

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)

Q
“ECO Accelerator Guidance”
A blue zone is displayed in the Eco area which can be used as a
reference operation range for using the accelerator pedal according
to driving conditions such as starting off and cruising.
The “ECO Accelerator Guidance” display changes according to the driv-
ing status, such as when starting off or cruising.
It is easier to drive in an Eco-friendly manner by driving according to the
display showing the accelerator pedal operations and staying within the
“ECO Accelerator Guidance” range. (P. 310)

Eco score
The driving status for the following 3 situations are evaluated in 5
levels: Smooth start-off acceleration (“Eco-Start”), driving without
sudden acceleration (“Eco-Cruise”) and smooth stopping (“Eco-
Stop”). Each time the vehicle is stopped, a score result is displayed
out of a perfect score of 100 points.

How to read the bar display:
*: For items not currently evaluated, the display reads 0.
OThe Eco score is reset each time the vehicle starts off to start a new
evaluation.
OWhen the shift position is P, only the Eco score display area is
enlarged and displayed. When the shift position is shifted from P,
the display returns to normal.
OWhen the hybrid system stops, the current total score result and
advice on how to increase the score are displayed. (P. 198)
