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.

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.

●

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

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)

●

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.

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.
