Outside temperature display

●

In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has changed suddenly (at the entrance/

exit of a garage, tunnel, etc.)

●

When “-” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Toyota dealer.

■

Electricity consumption
When the unit is set to “MPH”:
Electricity consumption is the consumption rate of the electricity when EV
driving is performed and equivalent to the fuel consumption for the gasoline
vehicles. For this vehicle, driven distance per kWh of electricity consumed
(“miles/kWh”) is displayed as electricity consumption on each screen.
When the unit is set to “km/h”:
Electricity consumption is the consumption rate of the electricity when EV
driving is performed and equivalent to the fuel consumption for the gasoline
vehicles. For this vehicle, electricity consumed per 100 km (“kWh/100 km”) is
displayed as electricity consumption on each screen.

■

Distance to empty

●

This distance is computed based on your average fuel consumption. As a
result, the actual distance that can be driven may differ from that displayed.

●

When only a small amount of fuel is added to the tank, the display may not
be updated.
When refueling, turn the power switch off. If the vehicle is refueled without
turning the power switch off, the display may not be updated.

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 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.

“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. (

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.

● The Eco score is reset each time the vehicle starts off to start a new

evaluation.

● When 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.

● When the hybrid system stops, the current total score result and

advice on how to increase the score are displayed. (

When operation of each function stops

●

The Hybrid System Indicator stops operating in the following situations.
• 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 used.

■

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. 215)

• 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. 94)

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. 110)

●

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. 94) 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 contin-
ues 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.

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 12 mph (20 km/h).

●

In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (

P. 241). 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.

■

Predictive Efficient Drive (Predictive Deceleration Support)
(vehicles with 11.6-inch display)
When a predictive deceleration support point registered in the navigation sys-
tem is approached, the system turns off the Eco accelerator guide and
informs the driver of releasing the accelerator pedal early.
For details about Predictive Efficient Drive (Predictive Deceleration Support),
refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.

“Fuel Consumption Record”



When the unit is set to “MPH”

The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 mile (1.6 km) or 5 miles
(8 km) of driving.



When the unit is set to “km/h”

The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 km (0.6 mile) or 5 km
(3.1 miles) of driving.
