Plug-in hybrid system
EV driving range
The value displayed on the multi-information display etc. (P. 214,
230, 237, 254) is estimated fro m the following information.
● The amount of hybrid battery (tr action battery) charge currently
remaining
● The electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
● Past air conditioning system el ectricity consumption amount
The electricity consumption va ries depending on how the vehicle is
driven. The vehicle automatically records the electricity consumption
when being charged and uses the el ectricity consumption for estimat-
ing the EV driving range. Therefor e, the EV driving range displayed
when the hybrid battery (traction battery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change significantly with each chargin g
until the electricity consumptio n based on the recorded value i s stable
(for approximately the first mont h or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving r ange
(with using the air conditioning system) is estimated based on the past
air conditioning electricity consumption amount considering tha t the
electricity consumpt ion may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distan ce that EV driving (driving using
only the electric motor) is possi ble, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine a nd electric motor are used depend-
ing on the situation. ( P. 9 6 )

Plug-in hybrid system
Charging methods
◆Charging from an external power source (P. 147)
This is a charging method used when charging from an AC outlet
(120 V) with the charging cable equipped to the vehicle or char ging
at a public charging station.
The charging start time (or departure time) and day can be set to carry
out charging using the charging schedule at the desired date an d time.
( P. 158)
◆Using the hybrid battery (tr action battery) charge mode
( P. 89)
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (tractio n bat-
tery) using electric ity generated by gas oline engine operation.
The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
The time required to charge the hybrid battery (traction battery) differs
according to the charging vol tage and charging current.
*1: This is the maximum value. Furthermore, the upper limit of the charging
current can be changed in the “Vehicle Settings” settings. ( P. 1 3 3 )
*2: The time required for charging to complete depends on conditions such as
the remaining charge of the hybrid battery (traction battery), the outside
temperature and specifications of a charger (charging station).
The following methods can be used to charge the hybrid battery
(traction battery).

■BSM (Blind Spot Monitor) outsid e rear view mirror indicators
(if equipped) ( P. 427)
• When the BSM function is enabled on the screen of the multi-infor- mation display, the power switch is turned to ON mode.
If the system is functioning correctly, the BSM outside rear vi ew mirror indi-
cators will turn off after a few seconds.
If the BSM outside rear view mirror indicators do not illuminat e or do not
turn off, there may be a malfunction in the system.
If this occurs, have the vehicle inspected by your Toyota deale r.
●
Indicators are also displayed on the out-
side rear view mirrors.
● In order to confirm operation, the BSM
outside rear view mirror indicators illumi-
nate in the following situations:
• When the power switch is in ON
mode, the BSM function is enabled
on the screen of the multi-infor-
mation display.
WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning li ght not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could result
in death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature warning
light comes on or flashes. In this case, immediately stop the v ehicle in a
safe place, and check the engine after it has cooled completely. (P. 718)

◆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 ti res 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 th e actual
contents of the display will differ.

■When operation of each function stops
● The Hybrid System Indicator stops operating in the following si tuations.
• 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 us ed.
■ Display of the remaining hyb rid battery (traction battery)
● The current amount of the remaining hybrid battery (traction ba ttery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
( P. 217)
• The remaining battery for EV driving in EV mode is displayed i n 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. 95)
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. 111 )
● 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. 95) or electricity
is generated by the gasoline engine. However, this does not ind icate a mal-
function. Also, even if the display of the remaining hybrid bat tery (traction
battery) exceeds the top line, the display is shown in blue unt il 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 re maining
hybrid battery (traction battery) is shown during charging, cha rging contin-
ues even after the display of the remaining hybrid battery (tra ction battery)
shows a fully charged state. However, this does not indicate a malfunction.
Please wait until charging is finished. The hybrid battery (traction battery)
is fully charged
