EV driving range
The value displayed on the multi-information display etc. (P. 212,
228, 235, 252) 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 5 )

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. 112)
● “Charging Complete” is displayed on the multi-information displ ay
when starting off ( P. 140)
Regardless of the type of power source or whether the charging timer
function is used, charging is c ompleted if the above can be confirmed.

■Hybrid battery (traction battery) warming control (Alaska and
Canada only)
This control operates after the charging cable remains connected to
the vehicle for 3 days and “Traction Battery Heater” automatica lly
stops. It automatically insulates the hybrid battery (traction battery)
in extremely low temperatures.
● This control stops 31 days after the charging cable is connected,
even if it is still connected to t he vehicle.
● When this control operates, timer charging settings are ignored
and charging starts.
■“Traction Battery Cooler”
When the hybrid battery (traction battery) is hot, this functio n pro-
tects it by using the vehicle air conditioning to cool it befor e
charging is carried out.
When the hybrid battery (trac-
tion battery) is above a certain
temperature and the power
switch is turned off, a check
screen is displayed on the
multi-information display that
indicates whether “Traction Bat-
tery Cooler” is implemented.
When “No” is selected, the hybrid battery (traction battery) co oling sys-
tem does not operate.

■“Traction Battery Cooler”
●When the hybrid battery (traction battery) is above a certain temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Co oler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this s creen, sys-
tem operation becomes possible.
● When charging starts, “Traction Battery Cooler” only operates i f the hybrid
battery (traction battery) temperature is hot.
● The charging indicator is illuminated while “Traction Battery C ooler” is on
standby or operating.
● “Traction Battery Cooler” is implemented for a maximum of approximately
30 minutes. However, when the “Departure” time is set ( P. 157) and there
is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become s horter.
● When there is a small amount of remaining charge in the hybrid battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.
● When the following operations are performed while “Traction Bat tery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.
• A door is opened
• The hood is opened
• The power switch is turned to any mode other than off
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( P. 5 2 2 )
• “Charge Now” is implemented ( P. 1 5 8 )
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
● When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Batt ery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display ( P. 246). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
● “Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of th e remaining
charge of the hybrid battery (traction battery) increases and d ecreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as ch arging by a
charging equipment. The charging equipment that calculates the fee
according to charging time causes a charging fee.

(P. 157) can be used to set the
system to automatically fully
charge the hybrid battery (traction
battery) before your desired depar-
ture time. It is also possible to set
the air conditioning to make the
interior in a comfortable state
before your desired departure time.
At your destination
Use a public charging station to
charge the hybrid battery (traction
battery).
If there are no charging facilities at
your destination, the hybrid battery
(traction battery) can be charged
using the hybrid battery (traction
battery) charge mode. ( P. 89)

■Timer settings
●The charge schedule cannot be set while driving.
● A maximum of 15 charge schedules can be registered.
■ To make sure that the charging timer function operates correctl y
Check the following items.
● Adjust the clock to the correct time ( P. 197)
● The calendar is set to the correct date ( P. 199)
● Check that the power switch is turned off
● After registering the charge schedule, connect the charging cable
The charging start time is determined based on the charge sched ule at the
time that the charging cable was connected.
● After connecting the charging cable, check that the charging indicator
flashes ( P. 114)
● Do not use an outlet that has a power cut off function (including a timer func-
tion)
Use an outlet that constantly supplies electricity. For outlets where the
power is cut off due to a timer function, etc., charging may no t be carried
out according to plan if the power is cut off during the set ti me.
■ When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, t he next
charge will not be carried out according to the timer until the charging cable is
removed and reconnected after charging completes. Also, when th e hybrid
battery (traction battery) is fully charged, charging according to the timer will
not be carried out.
■ “Climate Prep”
●When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. Therefore, the air condi tioning will con-
sume electricity and charging may not complete by the set depar ture time.
● If the hybrid battery (traction battery) is fully charged, char ging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will c onsume electricity
and the remaining charge of the hybrid battery (traction batter y) when
departing may be decreased.
■ Smartphone-linked operation (vehicles with 11.6-inch display)
After applying to Entune, it is possible to use the smartphone application to
change charging timer settings.
