◆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)
*1: Vehicles with 7-inch display
*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
*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. 110)
● “Charging Complete” is displayed on the multi-information displ ay
when starting off ( P. 137)
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.

■Opening the charging port lid
Vehicles without smart lid &
connector locking system:
Press the rear edge of the
charging port lid (the position
shown in the illustration).
Push and take your hand away
to slightly open the charging port
lid. Then open the lid fully by
hand.
Vehicles with smart lid & con-
nector locking system:
