Plug-in hybrid system features
The plug-in hybrid system is a system that has the features of both
electric vehicles and hybrid vehicles.
●Electricity received by charging from an external power
source can be used, and the vehicle can also be driven as an
electric vehicle by driving over certain distances* using only
the electric motor (traction motor).
●If the amount of electricity remaining in the hybrid battery
(traction battery) becomes low, the vehicle is automatically
controlled in such a way that it can be driven as a hybrid vehi-
cle through the joint use of the gasoline engine.
*: The driving range will vary in accordance with conditions such as vehi-
cle speed, the amount of charge remaining in the hybrid battery (trac-
tion battery) and the usage of the air conditioning system. The gasoline
engine may also be used simultaneously in accordance with driving
conditions.

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating, and are not a malfunction.
●The brake system operation sound heard from the front of the vehicle
when the driver’s door is opened.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind
the rear seat when the hybrid system starts or stops.
●Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when you press the
brake pedal or release the accelerator pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent. (→P. 4 5 )
●The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

Plug-in hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■Using EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV
mode when driving on highways (or freeways) can help con-
serve fuel and electricity. (→P. 3 7 )
■Using Eco drive mode
When using Eco drive mode, a torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving fuel and electricity economy. (→P. 2 4 9 )
■Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. (→P. 2 7 0 )
■When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained 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 encountering a delay, 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.

■Highway driving
Control your speed and keep at a constant speed. Also, 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 retained when slowing down.
Electricity consumption will increase substantially 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, driving in
HV mode while on the freeway and in EV mode after leaving the
freeway is recommended.
■Air conditioning on/off
●Switch the air conditioning ( ) to off when it is not
needed. Doing so can help control excessive electricity and
fuel consumption.
In summer: In high temperatures, use the recirculated air
mode. Doing so will help to reduce the burden on the air con-
ditioner and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically
cut out until the gasoline engine and the interior of the vehicle
are warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
●For efficiency, use the Remote Air Conditioning System
before departing while the charging cable is connected.

EV driving range
The EV driving range displayed on the multi-information display
shows the approximate driving range in EV mode, and the actual dis-
tance that can be driven may differ from that displayed.
■Displayed value
The value displayed on the multi-information display is calcu-
lated from the following information.
●The amount of hybrid battery (traction battery) charge cur-
rently remaining
●The electricity consumption (the estimated distance that can
be driven in EV mode per unit of electrical energy) based on
the recorded value
●Air conditioning on/off
The electricity consumption varies depending on how the vehicle
is driven. The vehicle automatically records the electricity con-
sumption when being charged and uses the electricity consump-
tion for calculating the estimated 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 estimated 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 indicate a malfunction.
When the air conditioning system is turned on, the estimated EV
driving range is calculated to be approximately 10% shorter
compared to when the air conditioning system is off in consider-
ation for an increase in electricity consumption.
