gently and a timely manner.
A greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
high fuel and electricity con-
sumption. Check traffic reports
before leaving and avoid delays
as much as possible. When driv-
ing in a traffic jam, gently
release the brake pedal to allow
the vehicle to move forward
slightly while avoiding overuse
of the accelerator pedal. Doing
so can help control excessive
electricity and fuel consumption.
 Control and maintain the vehi-
cle at a constant speed.
Before stopping at a toll booth
or similar, allow plenty of time
to release the accelerator and
gently apply the brakes. A
greater amount of electrical
energy can be regenerated
when slowing down.
 Electricity consumption will
increase significantly when
driving at high speeds in EV
mode or AUTO EV/HV mode.
If there will be a long distance
to the next external charging
point after leaving a freeway, it is recommended to drive in
HV mode while on the free-
way and change to EV mode
or AUTO EV/HV mode after
leaving the freeway. (
P.74)
 Turn the “A/C” switch off
when it is not needed. Doing
so can help reduce excessive
electricity and fuel consump-
tion.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doin g so will help to
reduce the burden on the air condi-
tioning system and reduce electric-
ity and fuel consumption as well.
In winter: Avoid excessive and
unnecessary use of the heater.
Usage of the heated steering wheel
(if equipped) and seat heaters (if
equipped) are effective. ( P.443)
Make sure to check the tire infla-
tion pressure frequently. If there
is improper tire inflation pres-
sure 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 to
increased fuel and electricity
consumption.

■Release the accelerator
pedal early before stopping
the vehicle, such as at a
traffic light
The regenerative brake will
operate to convert the kinetic
energy of the vehicle into electri-
cal energy, which will charge the
hybrid battery (traction battery).
The regeneration status can be
checked from the Hybrid Sys-
tem Indicator. ( P.158)
When the brake pedal is
depressed lightly during decel-
eration, the regeneration
amount increases, enabling
more electrical energy to be
recovered.
If the brake pedal is depressed too
strongly, the recovered amount
indicator will reach the maximum
level and the upper limit of the
recoverable en ergy will be
exceeded. Therefore, be sure to
operate the brake pedal early.
■Use the air conditioning
system appropriately, and
also utilize the heated steer-
ing wheel (if equipped) and
seat heaters (if equipped)
In EV mode, the vehicle is
cooled and heated by electrical
energy. (Except in extremely
cold temperatures of approxi-
mately 14°F [-10°C] or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and
improve electrical efficiency. When eco air conditioning mode
is used, the air conditioning con-
trol is switched automatically to
a lower setting. (
P.437)
The heated steering wheel and
seat heaters are efficient heat-
ing device that directly warm the
body using less electric power.
When used together with the air
conditioning system, a low tem-
perature setting can be used to
improve electrical and fuel effi-
ciency.
■Check the tire pressure
If the tire pressure is lower than
the specified value, it will
worsen the electrical and fuel
efficiency.
A pressure level 7 psi (50 kPa, 0.5
kgf/cm
2 or bar) lower than the spec-
ified value will cause a worsening of
several percentage points.
■When driving on highways,
use the EV/HV mode selec-
tion switch to drive in HV
mode
The power consumption will
increase significantly if the vehi-
cle is driven in EV mode on
highways.
■Do not load unnecessary
objects in the vehicle
Driving with objects weighing
220 lb. (100 kg) in the vehicle
will worsen the electrical and
fuel efficiency by approximately
3%.
Air resistance also greatly

WARNING
■When charging
Observe the following precau-
tions.
Failure to do so may cause an
unexpected accident, resulting in
death or serious injury.
●Connect to a power source suit-
able for charging. ( P.106)
●Check that the AC charging
cable, plug and outlet are free of
foreign matter.
●Before charging, check that the
AC charging inlet is not
deformed, damaged or cor-
roded, and check that the inlet
is free of foreign matter such as
dirt, snow and ice.
If there is dirt or dust in these
areas, remove completely
before inserting the charging
connector.
●Only use outlets where the plug
can be securely inserted.
●Do not bundle or wind the AC
charging cable while charging,
as doing so may result in over-
heating.
●Do not touch the terminals of
the charging connector and AC
charging inlet with a sharp metal
objects (needles etc.) or hands,
or short them with foreign
objects.
●When charging outdoors, make
sure to connect to a weather-
proof outlet for outdoor use.
Ensure the weatherproof outlet
cover closes co mpletely. If the
weatherproof outlet cover can-
not be closed, install a weather-
proof outlet cover that will close.
●In order to stop charging at the
charging station, follow the
instructions of the charger.
●If any heat, smoke, odors, noise
or other abnormalities are
noticed during charging, stop
charging immediately.
●Do not insert the plug if the out-
let is submerged in water or
snow.
●When charging while it is raining
or snowing, do not connect or
disconnect the plug if your
hands are wet. Also, do not get
the plug or outlet wet.
●Do not charge the vehicle
during a lightning storm.
●Prevent the AC charging cable
from being caught in the door or

Circuit Interrupting Device).
●Firmly insert the plug into the
outlet.
●Do not use an extension cord
and converting adaptor.
●Close the hood before using the
charging system. The cooling
fan may start operating sud-
denly. Touching or getting close
to rotating parts such as the fan
may cause your hands or
clothes (especially a necktie or
