mode after leaving the freeway.
(P.86)
Turn the “A/C” switch off when it
is not needed. Doing so can help
reduce excessive electricity and
fuel consumption.
In summer: When the ambient tem-
perature is high, use the recirculated air
mode. Doing so will help to reduce the
burden on the air conditioning system
and reduce electricity and fuel con-
sumption as well.
In winter: Avoid excessive and unnec-
essary use of the heater. Usage of the
heated steering wheel (if equipped)
(P.416) and seat heaters (P.417)
are effective.
Using the Remote Air Condition-
ing System (P.414) while the
AC charging cable is connected
to the vehicle can reduce elec-
tricity consumption immediately
after starting off by operating air
conditioning mainly using elec-
tricity from an external power
source.
When setting the charging
schedule, setting the charging
mode to “Departure” and “Cli-
mate Prep” to on can reduce
electricity consumption immedi-
ately after starting off by operat-
ing air conditioning before
charging is completed. (P.143)Make sure to check the tire inflation
pressure frequently. If there is
improper tire inflation pressure in
the tires, the EV driving range will
become shorter, and fuel consump-
tion when in HV mode will increase.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to increased fuel
and electricity consumption.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a
large roof rack will also cause poor
fuel economy.
Since the gasoline engine starts up
and cuts out automatically, warm-
ing up is not necessary.

The value displayed on the SOC
(State of Charge) gauge (P.172)
is estimated from the following
information.
The amount of hybrid battery
(traction battery) charge cur-
rently remaining
The electricity consumption (the
estimated distance that EV driv-
ing is possible per unit of electri-
cal energy) based on the
recorded value
Past air conditioning system
electricity consumption amount
The electricity consumption varies
depending on how the vehicle is
driven. The vehicle automatically
records the electricity consumption
when being charged and uses the electricity consumption for estimat-
ing the EV driving range. Therefore,
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 charging
until the electricity consumption
based on the recorded value is sta-
ble (for approximately the first
month or two). However, this does
not indicate a malfunction.
When the air conditioning system is
turned on, the EV driving range
(with using the air conditioning sys-
tem) is estimated based on the past
air conditioning electricity con-
sumption amount considering that
the electricity consumption may
become higher.
The distance that EV driving is pos-
sible varies significantly depending
on how the vehicle is driven, road
conditions, the weather, the outside
temperature, usage conditions of
electrical components and the num-
ber of occupants.
The distance that EV driving is pos-
sible can be extended if the follow-
ing is performed:
EV driving range
The EV driving range displayed
on the multi-information dis-
play shows the reference dis-
tance that EV driving (driving
using only the electric motor)
is possible, and the actual dis-
tance that can be driven may
differ from that displayed.
Even if the EV driving range is
displayed, EV driving may be
canceled and both gasoline
engine and electric motor are
used depending on the situation.

QWhen starting off, depress the
accelerator pedal smoothly to
accelerate
As a guide, accelerate up to
approximately 20 km/h (12mph) in
the first 5 seconds.
Electrical and fuel efficiency can be
improved just by using the ECO
Accelerator Guidance displayed on
the multi-information display and
taking care to start off gently.
(P.180)
When the driving mode is set to Eco
drive mode, depressing the accelerator
pedal generates smooth torque that
makes it easier to operate the accelera-
tor gently.
QMaintain sufficient vehicle-to-
vehicle distance and do not
accelerate or decelerate
unnecessarily
Try to maintain a fixed speed while
driving. Driving at a short vehicle-
to-vehicle distance will result in
repeating wasteful acceleration and
deceleration, which will worsen the
electrical and fuel efficiency.
QRelease the accelerator pedal
early before stopping the vehi-
cle, such as at a traffic light
The regenerative brake will operate
to convert the kinetic energy of the
vehicle into electrical energy, which
will charge the hybrid battery (trac-
tion battery).
The regeneration status can be
checked from the Hybrid System
Indicator. (P.175)When the brake pedal is depressed
lightly during deceleration, the
regeneration amount increases,
enabling more electrical energy to
be recovered.
If the brake pedal is depressed too
strongly, the recovered amount indica-
tor will reach the maximum level and
the upper limit of the recoverable
energy will be exceeded. Therefore, be
sure to operate the brake pedal early.
QUse the air conditioning sys-
tem appropriately, and also
utilize the heated steering
wheel (if equipped) and seat
heaters
In EV mode, the vehicle is cooled
and heated by electrical energy.
(Except in extremely cold tempera-
tures of approximately -10°C (14°F)
or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and improve
electrical efficiency.
The heated steering wheel (if
equipped) and seat heaters are effi-
cient heating device that directly
warm the body using less electric
power.
When used together with the air condi-
tioning system, a low temperature set-
ting can be used to improve electrical
and fuel efficiency.
QCheck the tire pressure
If the tire pressure is lower than the
specified value, it will worsen the
electrical and fuel efficiency.

1282-2. Charging
QHybrid battery (traction bat-
tery) warming control (Green-
land only)
This control operates after the AC
charging cable remains connected
to the vehicle for 3 days and “Bat-
tery Heater” automatically stops. It
automatically insulates the hybrid
battery (traction battery) in
extremely low temperatures.
This control stops 31 days after
the AC charging cable is con-
nected, even if it is still con-
nected to the vehicle.
When this control operates,
charging schedule settings are
ignored and charging starts.
Q“Battery Cooler”
When the hybrid battery (traction
battery) is hot and the AC charging
cable is connected to the vehicle,
this function cools the hybrid bat-
tery (traction battery) before
charging is carried out.
“Battery Cooler” will operate when
the “Battery Cooler” of the
“Charging Settings” on the multi-
information display is on. (P.185)
QTraction battery heating and cool-
ing system (“Battery Heater” and
“Battery Cooler”)
OThe system operates when the hybrid
battery (traction battery) is below or
above a certain temperature.
OThe system may operate when
charging is not being performed.
OWhen the charging schedule is used
(P.143), this function will operate according to the charging schedule.
Q“Battery Heater”
OWhen “Battery Heater” is operating,
the charging indicator illuminates.
OWhen the AC charging cable is
removed from the vehicle or remains
connected to the vehicle for approxi-
mately 3 days, the system automati-
cally stops.
OWhen “Battery Heater” is operating
during charging, the charging time
may be longer than normal.
OIf the outside temperature becomes
high while “Battery Heater” is operat-
ing, charging may complete earlier
than the “Departure” time set.
(P.143)
OWhen the traction battery is almost
completely charged, “Battery Cooler”
may not be implemented.
OWhen the following operations are
performed while “Battery Heater” is
operating, the hybrid battery (traction
battery) heating operation stops.
• The shift lever is changed to any posi-
tion other than P
• The Remote Air Conditioning System
is operated (P.414)
O“Battery Heater” may operate even
when the hybrid battery (traction bat-
tery) is fully charged depending on the
temperature of the hybrid battery
(traction battery).
• The remaining charge of the hybrid
battery (traction battery) decreases
when “Battery Heater” operates. The
charging operation may start again to
charge the hybrid battery (traction bat-
tery).
• “Charging Stopped Due to Pulled
Charging Connector” may be shown
when the charging connector is
removed while recharging. (P.159)
Q“Battery Cooler”
OThe charging indicator is illuminated
while “Battery Cooler” is on standby or
operating.
O“Battery Cooler” is implemented for a

maximum of approximately 30 min-
utes. However, when the “Departure”
time is set (P.143) and there is not
sufficient time between the current
time and the time that charging will
complete, “Battery Cooler” operation
time may become shorter.
OWhen there is a small amount of
remaining charge in the hybrid battery
(traction battery), even if the hybrid
battery (traction battery) is hot, “Bat-
tery Cooler” may not be implemented.
OWhen the following operations are
performed while “Battery Cooler” is
operating, the hybrid battery (traction
battery) cooling operation stops.
• The hood is opened
• The power switch is turned to any
mode other than off
• The Remote Air Conditioning System
is operated (P.414)
• “Charge Now” is implemented
(P.144)
O“Battery Cooler” uses the power of the
hybrid battery (traction battery) and
external power source.
• While “Battery Cooler” is operating,
the amount of the remaining charge of
the hybrid battery (traction battery)
increases and decreases in a certain
range, and does not increase as in
normal charging.
• The operation of “Battery Cooler” is
recognized as charging by a charger.
The charger that calculates the fee
according to charging time causes a
charging fee.
To enable the use of EV mode or
AUTO EV/HV mode, we recom-
mend systematically charging the
vehicle.
QBefore leaving home
In order to use EV mode or AUTO
EV/HV mode, charge the hybrid
battery (traction battery) at home
before leaving.
The charging schedule function
(P.143) can be used to set the sys-
tem to automatically fully charge the
hybrid battery (traction battery) before
your desired departure time. It is also
possible to set the air conditioning to
make the interior in a comfortable state
before your desired departure time.
QAt your destination
Use a public charging station to
charge the hybrid battery (traction

each part of the AC charging cable
is in good condition. (P.116)
QDuring charging
OThe charging starting time may differ
depending on the state of the vehicle,
but this does not indicate a malfunc-
tion.
OCooling fan sounds may be heard
from near the rear seat. (P.98)
ODuring charging, sounds may be
heard from near the hybrid battery
(traction battery) in accordance with
the operation of the air conditioning
system or “Battery Cooler” (P.128).
ODuring and after charging, the rear
seat and its surrounding area in which
the onboard traction battery charger is
installed may get warm.
OThe surface of the CCID (Charging
Circuit Interrupting Device) may
become hot, but this does not indicate
a malfunction. (When using Mode 2
AC charging cable.)
ODepending on radio wave conditions,
interference may be heard on the
radio.
OThe current charging condition and
the estimated time until charging will
complete can be checked on the
multi-information display.
QCapacity reduction of the hybrid
battery (traction battery)
The capacity of the hybrid battery (trac-
tion battery) will decline gradually when
the hybrid battery (traction battery) is in
use. The rate at which it declines will dif-
fer in accordance with environmental
conditions and the way in which the
vehicle is used. Observing the following
can help suppress battery capacity
decline.
OAvoid parking the vehicle in areas with
a high temperature under direct sun-
light when the hybrid battery (traction
battery) is fully charged.
OAvoid accelerating and decelerating frequently and suddenly when EV
driving.
OAvoid frequent driving near the top
speed for EV driving. (P.90)
OLeave a low level of charge in the
hybrid battery (traction battery) when
leaving the vehicle undriven for a long
period of time.
After confirming that EV mode or
AUTO EV/HV mode has switched to
HV mode, turn the power switch off.
OUse the charging schedule function as
much as possible in order to fully
charge the hybrid battery (traction bat-
tery) immediately before starting off.
(P.143)
Also, if the hybrid battery (traction bat-
tery) capacity reduces, the distance that
can be driven in EV mode or AUTO
EV/HV mode decreases. However, vehi-
cle performance does not significantly
become worse.
QWhen the remaining charge of the
hybrid battery (traction battery) is
low after charging
In the following situations, the remaining
charge of the hybrid battery (traction
battery) after charging completes may
be less than normal in order to protect
the system (the EV driving range after
the battery is fully charged may be
shorter).
*
OCharging is carried out when the out-
side temperature is low or high.
OCharging is carried out immediately
after high-load driving or in extreme
heat.
When none of the above situations
apply and there is a drastic drop in the
remaining charge of the hybrid battery
(traction battery) after charging com-
pletes, have the vehicle inspected by
any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
*: When this occurs, even if the remain-
ing charge display of the hybrid bat-
tery (traction battery) shows that it is

QCalendar settings
Current date and time information is
automatically set using GPS. However,
if GPS calibration of clock is turned off in
the multimedia system settings, the date
needs to be set on the multi-information
display.
If the calendar settings check screen is
displayed when an attempt was made to
register a charge schedule, check that
the correct date is set. If it is incorrect,
be sure to correct it.
If the calendar information is wrong, the
charging schedule function will not oper-
ate normally.
When registering the charging
schedule, the following settings can
be changed.
QSelect the charging mode
One of the two following charging
modes can be selected.
“Start”
Starts charging at the set time*1 and fin-ishes charging when fully charged.
*2
“Departure”
Starts charging to finish at the set
time.
*3, 4
When this setting is selected, the air
conditioning-linked function can be
used.
*1: Charging schedule function is per-
formed in accordance with the clock
in the multi-information display.
Before registering the charging
schedule, check the clock settings to
the proper time.
*2: There might be a slight error in the
timing when charging starts due to
the state of the hybrid battery (trac-
tion battery).
*3: When the system determines that
there is no time to finish charging by
the set scheduled departure time, it
starts charging. Check the charging
schedules.
*4: If sudden changes in temperature or
changes in the condition of the
power source occur while charging,
charging may not end exactly at the
time estimated by the system.
QRepeated setting
The periodic charging schedule can
be set by selecting your desired
day of the week. (If no days are
selected, charging is only carried
out once.)
QAir conditioning-linked set-
ting (“Climate Prep”)
When the charging mode is set to
“Departure”, the vehicle air condi-
tioning system (P.406) can be set
to automatically operate
* according
Using the charging
schedule function
Charging can be carried out at
the desired time by registering
the charging schedule. Also, it
is possible to set the charging
schedule to one’s prefer-
ences, such as having
charging complete by a certain
departure time or be carried
out at the same time on certain
days.

connected.
OAfter connecting the AC charging
cable, check that the charging indica-
tor of the charging port flashes
(P.106)
ODo not use an socket that has a power
cut off function (including a timer func-
tion)
Use an socket that constantly supplies
electricity. For sockets where the
power is cut off due to a timer func-
tion, etc., charging may not be carried
out according to plan if the power is
cut off during the set time.
QWhen the AC charging cable
remains connected to the vehicle
Even if multiple consecutive charging
schedules are registered, the next
charge will not be carried out according
to the charging schedule until the AC
charging cable is removed and recon-
nected after charging completes. Also,
when the hybrid battery (traction battery)
is fully charged, charging according to
the charging schedule will not be carried
out.
Q“Climate Prep”
OWhen the air conditioning-linked set-
ting is turned on, the air conditioning
operates until the set departure time.
Therefore, the air conditioning will
consume electricity and charging may
not complete by the set departure
time.
OIf the hybrid battery (traction battery)
is fully charged, charging will not be
carried out, even if the charging
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 con-
sume electricity and the remaining
charge of the hybrid battery (traction
battery) when departing may be
decreased.
OWhen the doors are unlocked, the air
conditioning system does not operate.
QWhen charging schedules are
ignored
When the following operations are per-
formed while the charging schedule is
on standby, charging schedule is tempo-
rarily canceled and charging is started.
OWhen the Remote Air Conditioning
System (P.414) is operated
OWhen turning “My Room Mode” on
(P.152)
OWhen turning “Charge Now” on
(P.149)
OWhen an operation that temporarily
cancels charging using the charging
schedule is performed (P.137)
QEffects of outside temperature
When the charging mode is set to
“Departure”, charging schedule may be
ignored due to the outside temperature
and charging may start.
Q“Battery Heater” (P.127) /“Battery
Cooler” (P.128)
When charging is carried out using the
charging schedule, the hybrid battery
(traction battery) heating or cooling func-
tion may operate according to the tem-
perature of the hybrid battery (traction
battery).
OWhen the charging mode is set to
“Start”, the function starts at the set
charging start time.
O“Battery Heater”: When the charging
mode is set to “Departure”, the func-
tion starts automatically to complete
heating by the desired departure time.
O“Battery Cooler”: When the charging
mode is set to “Departure”, cooling
starts approximately 30 minutes
before the charging start time. How-
ever, if there is no time to finish
charging by the charging schedule,
the hybrid battery (traction battery)
cooling time may be shortened and
“Battery Cooler” may not operate.
