◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
●Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leaving and avoid delays as much as
possible. When driving 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 exces-
sive electricity and fuel consumption.
◆Highway driving
●Control and maintain the vehicle 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. If there will be a long distance to the
next external charging point after leaving a freeway, it is recom-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

◆Air conditioning
●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 temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 520)
●Using the Remote Air Conditioning System (P. 516) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
●When setting the timer, selecting the start time setting mode and
setting “Climate Prep” to “On” can reduce electricity consumption
immediately after starting off by operating air conditioning before
charging is completed. (if equipped)
(P. 163)
◆Checking tire inflation pressure
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 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.
◆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. 210,
226, 233, 250) is estimated from the following information.
●The amount of hybrid battery (traction 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 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 stable
(for approximately the first month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning system) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumption may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, 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 and electric motor are used depend-
ing on the situation. (P. 9 8 )

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
●Maintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
●Accelerate and decelerate the vehicle 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 ( ) 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 increase substantially when driving on a
highway in EV mode.
●Do not add unnecessary weight to the vehicle
The following indicate that charging has been carried out properly.
●The charging indicator turns off
●The Hybrid battery (traction battery) status indicators illuminate for
approximately 15 seconds. (P. 1 1 5 )
●“Charging Complete” is displayed on the multi-information display
when starting off (P. 146)
Regardless of the type of power source or whether the charging timer
function is used, charging is completed if the above can be confirmed.
