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 )

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the we ather,
the outside temperature, usage con ditions of electrical components
and the number o f occupants.
The distance that can be driven in EV mode can be extended if t he fol-
lowing is performed:
● Maintain a safe distance from t he vehicle in front and avoid un nec-
essary acceleration and deceleration
● Accelerate and decelerate the v ehicle as smoothly as possible
● Drive at moderate speeds as much as possible and maintain a con -
stant speed
● Set the air conditioning to a moderate temperature and turn the “A/C”
switch (
*1 • *2) off when it is not needed
● Use tires of the specified size and maintain the specified tire pres-
sure
● Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will in crease substantially when drivin g on a
highway in EV mode.
● Do not add unnecessary w eight to the vehicle
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
The following indicate that charging has been carried out prope rly.
● The charging indicator turns off
● The Hybrid battery (traction battery) status indicators illumin ate for
approximately 15 seconds. ( P. 113)
● “Charging Complete” is displayed on the multi-information displ ay
when starting off ( P. 141)
Regardless of the type of power source or whether the charging
schedule function is used, charging is completed if the above c an be
confirmed.

■Closing the charging port lid
Close the charging port lid and
press the rear edge of the
charging port lid (the position
shown in the illustration).
Vehicles with smart lid & con-
nector locking system:
• When the doors are locked with the smart key system,
wireless remote control or
door lock switch, the charging
port lid is also locked.
(P. 279, 281)
• If the charging port lid is closed with the doors locked,
the charging port lid locks.
When the charging cable is con-
nected to the charging inlet, the
user is informed of the charging
status of the hybrid battery (trac-
tion battery) by the statuses of 3
indicators (turned off, illuminated
or flashing).

ways.
*: Turns off after flashing for a certain period of time.
■Charging indicator
When a system malfunction occurs while charging or using the Re mote Air
Conditioning System, the charging indicator rapidly flashes for a certain
period of time, and then turns off.
If this occurs, the next time the hybrid system is started, a m essage is dis-
played on the multi-information display. When a message is displayed, follow
the instructions displayed on the screen.

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).
