◆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.
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.
●The arrows from the image of the engine to that of the electric
motor (traction motor) or tires 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 the actual
contents of the display will differ.

◆Hybrid 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. 227) and the head-up display (if equipped)
(P. 265).

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. 239)

settings. (P. 260)
*3: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.

■Display of the remaining hybrid battery (traction battery)
●The 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. 227)
• 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. 103)
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. 121)
●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. 103) 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).
●Depending 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)

Driving
■Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 300 km (200 miles):
Avoid sudden stops.
●For the first 1000 km (600 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 772)
■For efficient use
●Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will discharge, requiring unnec-
essary engine power to charge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor)
without having to use gasoline engine power.
●Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not charge. Leav-
ing the shift position in the N position for an extended period of time may
discharge the hybrid battery (traction battery). The vehicle cannot run if the
hybrid battery (traction battery) is discharged.
