◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on th e
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering w heel (if equipped) and seat heat-
ers is effective. ( P. 5 2 2 )
● Using the Remote Air Conditioning System ( P. 518) while the
charging cable is connected to the vehicle can reduce electrici ty
consumption immediately after st arting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode a nd
setting “Climate Prep” to “On” c an reduce electricity consumption
immediately after starting off by operating air conditioning be fore
charging is completed. ( P. 154)

*2: Vehicles with 11.6-inch display
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If t here is
improper tire inflation pressur e in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead t o increased fuel and electricity consumptio n.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

EV driving range
The value displayed on the multi-information display etc. (P. 207,
223, 230, 247) 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 3 )

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

■Capacity reduction of the hybr id battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental condition s and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
● Avoid parking the vehicle in areas with a high temperature unde r direct sun-
light when the hybrid battery (traction battery) is fully charged.
● Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
● Avoid frequent driving near the top speed for EV driving. ( P. 93)
● Leave a low level of charge in the hybrid battery (traction bat tery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
● Use the charging timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off. ( P. 154)
Also, if the hybrid battery (traction battery) capacity reduces , the distance that
can be driven in EV mode decreases. However, vehicle performanc e does
not significantly become worse.
■ When 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 or der to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
● Charging is carried out when the outside temperature is low or high
● Charging 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 your Toyota dealer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remainin g charge rapidly
decreases faster than normal.
