Display contents

Detail

Hybrid System Indicator

A convenient Hybrid System Indicator is displayed.
Refer to P. 225 for details on how to read the Hybrid
System Indicator.

Current electricity consumption

When  in  EV/EV  auto  mode,  the  current  electricity
consumption during driving is displayed.

• The 

 mark indicates the total average electric-

ity  consumption  since  last  reset  until  it  is  reset
again.

• When “Electricity Consumption Reset” (



P. 250)

is performed, the data of the total average elec-
tricity consumption is deleted and the 

 mark is

reset to 0.

Current fuel consumption

When  in  HV  mode,  the  current  fuel  consumption
during driving is displayed.

• The 

 mark indicates the value displayed in the

average  fuel  consumption  display  (



P.  213).

Switching  the  average  fuel  consumption  display
also changes the position of the 

 mark.

• When the average fuel consumption is reset, the

position of the 

 mark is reset to 0.

Hybrid battery (traction battery) status

The  same  contents  as  the  hybrid  battery  (traction
battery)  status  on  the  Hybrid  System  Indicator  are
displayed. (

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.

About the Eco score

●

After  starting  off,  Eco  score  display  does  not  start  until  the  vehicle  speed
exceeds approximately 19 mph (30 km/h).

●

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



P. 243). 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”.

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, ensure that the hybrid system is oper-
ating while setting up the display features.

attempt to insert it.
After  using  the  mechanical  key,  store  it  in  the  electronic  key.  Carry  the
