Plug-in hybrid system features
The illustration is an example for explanation and may differ from the
actual item.
Gasoline engine
Electric motor (traction motor)
The plug-in hybrid system is a system excellent in both econom-
ical efficiency of electric vehicles and practicality of hybrid vehi-
cles.
● EV driving can be performed using electricity charged from an
external power source.
*
●If the amount of electricity remaining in the hybrid battery (t raction
battery) becomes low, the vehicle is automatically controlled i n
such a way that it can be driven as a hybrid vehicle through the
joint use of the gasoline engine.
*: The EV driving range will vary in accordance with conditions s uch as
vehicle speed, the amount of charge remaining in the hybrid bat tery
(traction battery) and the usage of the air conditioning system. The gaso-
line engine may also be used simultaneously in accordance with driving
conditions.

■Switching to the hybrid battery (traction battery) charge mode
Press and hold the switch.
Take your hand off the switch
once the hybrid battery charge
mode indicator starts to blink.
The hybrid battery charge mode
indicator illuminates when the
switch to hybrid battery (traction
battery) charge mode is com-
plete.
When the hybrid battery (traction battery) is fully charged
*, the hybrid
battery (traction battery) charge mode is automatically cancele d and the
operation mode will be switched to HV mode.
The hybrid battery (traction battery) charge mode will be cance led by
pressing EV/HV mode selection switch or EV auto mode switch.
*: The maximum charge amount in the hybrid battery (traction batt ery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
■ If the plug-in hybrid system ope ration mode cannot be changed
In the following situations, the plug-in hybrid system operation mode cannot
be changed even if the EV/HV mode selection switch or EV auto mode switch
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
● When electricity needed for EV driving is not remaining (when in EV/EV
auto mode)
● When the traction battery is almost completely charged (hybrid battery [trac-
tion battery] charge mode)
■ When switching from EV mode to another mode using the switch
When the power switch is turned of f, operation mode switching is canceled
and the system returns to EV mode the next time the vehicle is started.
■ Hybrid battery (traction battery) charge mode
●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or cannot
cancel it
• Gasoline engine does not start or stops even after switching to hybrid bat- tery (traction battery) charge mode
● If a load to the system is large, such as when the power consumption of the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.

Plug-in hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it contains a high
voltage system (about 600V at maximum) as well as parts that
become extremely hot when th e hybrid system is operating.
Obey the caution labels attached to the vehicle.

Plug-in hybrid vehicle driving tips
◆Using EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV mod e
when driving on highways (or freeways) can help conserve fuel a nd
electricity. ( P. 9 0 )
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the acce l-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/coo ling) will be minimized, improving
fuel and electricity economy. ( P. 425)
◆Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System I ndi-
cator within Eco area. ( P. 225)
◆Shift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parkin g. When
using the N, there is no positiv e effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener -
ated. Also, when using the air conditioning system, etc., the h ybrid
battery (traction batt ery) power is consumed.
For economical and ecological dri ving, pay attention to the fol-
lowing points:

2-1. Plug-in hybrid system
◆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 3 5 )
● Using the Remote Air Conditioning System ( P. 531) 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 charging schedule, selecting the start time se t-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immedi ately after starting off by operating air
conditioning before c harging is completed. ( P. 158)

*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.
