■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)

■Remaining charge amount warning of hybrid battery (traction battery)
●The 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.
●When a warning message is shown on the multi-information display and the
buzzer sounds, follow the instructions displayed on the screen to perform
troubleshooting.
■About the Eco score
●After starting off, Eco score display does not start until the vehicle speed
exceeds approximately 30 km/h (19 mph).
●In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (P. 254). 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.
■“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.

◆“Drive Monitor 2”
The following information of EV driving is displayed.
Total average electricity con-
sumption
Indicates the total average
electricity consumption since
last reset until it is reset
again.
*1
EV driving range (without
using the air conditioning
system)
Indicates the estimated distance that can be driven using the cur-
rent remaining hybrid battery (traction battery). (P. 1 1 9 )
*2
EV driving range (with using the air conditioning system)
Indicates the estimated distance that can be driven using the cur-
rent remaining hybrid battery (traction battery) while using the air
conditioning system.
*2
Accumulated power generation quantity by the solar charging
system (if equipped)
Indicates the accumulated solar power generation quantity up
until now by the solar charging system.
*1: When “Electricity Consumption Reset” (P. 261) is performed, the data
of the total average electricity consumption is deleted.
*2: The EV driving range may shorten even when not driving due to power
consumption by the system.

◆“Eco-Diary”
The history of the average electricity consumption, air conditioning
system load ratio (“A/C Load Ratio”)
*, distance traveled and aver-
age fuel consumption can be displayed in a table according to day
(“Daily”) or month (“Monthly”) units.
*: It indicates the percentage of the electricity consumed from the hybrid
battery (traction battery) that is consumed by the air conditioning sys-
tem.

WARNING
■Cautions while setting up the display
As the hybrid system needs to be operating during setting up the display,
ensure that the vehicle is parked in a place with adequate ventilation. In a
closed area such as a garage, exhaust gases including harmful carbon
monoxide (CO) may collect and enter the vehicle. This may lead to death or
a serious health hazard.
NOTICE
■ While setting up the display
To prevent 12-volt battery discharge, ens ure that the hybrid system is oper-
ating while setting up the display features.

■Enabling/disabling of the head-up display
When the head-up display is turned off with the “HUD” switch, it is not dis-
played until the “HUD” switch is used to turn the head-up display on again.
(Operation of the head-up display is not linked with the power switch.)
■Display brightness
●The brightness of the head-up display is automatically adjusted according to
the operation status of the headlights (on/off) and the brightness of the sur-
roundings.
●When the brightness of the head-up display is adjusted to a certain level or
higher, the display automatically dims when the vehicle is stopped. Once the
vehicle starts off and the vehicle speed reaches approximately 5 km/h
(3.1 mph) or more, the display automatically returns to its previous bright-
ness.
■Vehicle speed display
In extremely cold environments, the display of the speedometer and the vehi-
cle speed of the head-up display may slightly differ.
■Head-up display
The head-up display may seem dark and hard to see when viewed through
sunglasses, especially polarized sunglasses.
■When the 12-volt battery is disconnected
The customize settings of the head-up display will be reset.
