• If electricity needed for EV driving in EV mode or AUTO
EV/HV mode is not remaining,
the operation mode will be
automatically switched to HV
mode.
• The operation mode can be switched to HV mode at any
timing by operating the switch
to keep electricity for EV driv-
ing etc. ( P.74).
* Switching
to HV mode when driving on a
highway or when driving uphill
is recommended in order to
conserve battery power.
When in HV mode, the HV drive
mode indicator illuminates.
*: The EV driving range may reduce even after switching to HV mode.
■Hybrid battery (traction bat-
tery) charge mode ( P.75)
Electricity generated by the gas-
oline engine can be used to
charge the hybrid battery (trac-
tion battery) by switching to the
hybrid battery (traction battery)
charge mode when electricity
needed for EV driving is not remaining.
*
• The system may not be able
to switch to the hybrid battery
(traction battery) charge
mode due to the state of the
plug-in hybrid system.
( P.76)
• Charging time differs depend- ing on the driving state of the
vehicle when driving in hybrid
battery (traction battery)
charge mode.
When in the hybrid battery (traction
battery) charge mode, the hybrid
battery charge mode indicator illu-
minates.
*: When in the hybrid battery (trac-tion battery) charge mode, the
hybrid battery can be charged
while driving. However, the gaso-
line engine runs to charge the
battery and fuel consumption
becomes higher compared with
driving in HV mode.
The plug-in hybrid system oper-
ation modes can be switched
using the switches.
■Switching the plug-in
hybrid system operation
modes
Press the AUTO EV/HV mode
switch or EV/HV mode selection
switch to change modes as the
following table shows.

using only the electric motor)* is
possible. However, depending
on the situation, EV driving may
be canceled and both gasoline
engine and electric motor are
used ( P.79). Also, if a little
electricity is remaining in the
hybrid battery (traction battery),
HV mode is automatically
selected. To drive in EV mode
long, observe the followings.
 Avoid sudden acceleration
and sudden deceleration, and
be sure to drive smoothly. If
you repeatedly accelerate,
the hybrid battery (traction
battery) charge will deplete
quickly. Also, EV driving may
be canceled by rapid acceler-
ation or vehicle speed.
 Restrain your speed as much
as possible. The distance that
can be driven in EV mode will
reduce considerably at high
speeds.
*: The EV driving range can be
checked using the meter.
( P.155)
■When in AUTO EV/HV mode
Only the electric motor is used
for EV driving
* during normal
driving, but when the accelera-
tor pedal is strongly depressed,
the gasoline engine starts.
( P.79)
Also, when the hybrid battery
(traction battery) level is low, the
mode switches to HV mode automatically the same as in EV
mode.
AUTO EV/HV mode is suitable
for driving conditions when more
power is required, such as for
driving uphill or accelerating
suddenly. However, because
the gasoline engine will start
more easily, it is recommended
to drive in EV mode usually.
*: The EV driving range can be
checked using the meter.
( P.155)
■When in HV mode
The vehicle can be used in the
same way as a standard Plug-in
Hybrid Electric Vehicle
In HV mode, controls are pri-
marily carried out as follows in
accordance with the driving con-
ditions.
 The gasoline engine stops
*
when the vehicle is stopped.
 During start off, the electric
motor (traction motor) drives
the vehicle.
 During normal driving, the
gasoline engine and electric
motor (traction motor) are
controlled effectively, and the
vehicle is driven with optimum
fuel efficiency. Also, when
necessary, the electric motor
(traction motor) operates as
an electrical generator to
charge the hybrid battery
(traction battery).

■Gasoline engine operation in
EV mode or AUTO EV/HV mode
Even if there is a sufficient amount
of electricity remain ing in the hybrid
battery (traction battery) and EV
driving range ( P.155) is being dis-
played on the meter, EV driving
(driving using only the electric
motor) may be canceled and both
gasoline engine and electric motor
are used depending on the situation
(EV driving will be returned to auto-
matically after EV driving becomes
possible again).
EV driving may be canceled auto-
matically in the following circum-
stances
*1:
●When vehicle speed is more than
approximately 84 mph (135 km/h).
●When power is needed temporar-
ily, for example when the acceler-
ator pedal is depressed firmly or
when accelerating suddenly.
*2
●When the temperature of the
hybrid system is high.
The vehicle has been left in the
sun, driven on a h ill, driven at high
speeds, etc.
●When the temperature of the
hybrid system is low.
●When the heater is switched on
when the outside temperature is
below about 14°F (-10°C).
●When the windshield defogger
switch is pressed. ( P.434)
●When the system determines that
the gasoline engine needs to be
started.
*1: The gasoline engine may also
operate in circumstances other
than those listed above, depend-
ing on conditions.
*2: When driving in AUTO EV/HV mode. Even in EV mode, the gas-
oline engine may start, depend-
ing on the condition of the hybrid
battery (traction battery).
■If “Engine Started to Protect
System EV driving unavailable”
is displayed on the multi-infor-
mation display
EV driving may be canceled in order
to protect the hybrid system, etc.
In this case, perform driving with the
gasoline engine until EV driving will
be returned to automatically.
Depending on the conditions, driv-
ing that combines the use of the
gasoline engine may continue for a
short while. However, this is not a
malfunction.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically . However, it
may not stop automatically in the
following conditions
*:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the windshield defogger
switch is pressed. ( P.434)
*: Depending on the circumstances,
the gasoline engine may also not
stop automatically in situations
other than those above.
■Sounds and vibrations specific
to a Plug-in Hybrid Electric
Vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
Plug-in Hybrid Electric Vehicle for
being off when it is actually still run-
ning, as indicated by the “READY”
indicator being illuminated. For
safety, make sure to always shift the
shift position to P and apply the
parking brake when parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion.

802-1. Plug-in hybrid system
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
when the hybrid system starts or
stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid battery (traction
battery), under the rear seats or
under the floor, when the hybrid
system is started or stopped.
●Sounds from the hybrid system
may be heard when the back door
is open.
●Sounds may be heard from the
transmission when the gasoline
engine starts or stops, when driv-
ing at low speeds, or during idling.
●Engine sounds may be heard
when accelerating sharply.
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Vibration may be felt when the
gasoline engine starts or stops.
●Sounds may be heard from near
the hybrid battery (traction battery)
in accordance with the operation
of the air conditioning system or
battery cooler. ( P.109)
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do not dispose of the
vehicle yourself.
In order to make EV mode or
AUTO EV/HV mode available,
charge the hybrid battery (trac-
tion battery) from an external
power source before using the
vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven.
However, if there is not enough
charge remaining, it is possible that
the vehicle cannot be driven in EV
mode or AUTO EV/HV mode or the
EV driving range will become
shorter.
■Refilling fuel
Plug-in Hybrid Electric Vehicles can
be driven using electricity charged
from an external power source.
However, as the gasoline engine is
used depending on the situation
(  P.79) even if in EV mode or
AUTO EV/HV mode, and the gaso-
line engine is provided on board as
a power source for driving in HV
mode, it is needed to refueling the
vehicle.
Check the fuel amount and refill
immediately when the fuel level
becomes low. ( P.279)
■If the vehicle is not used for a
long time
●The 12-volt battery may dis-
charge. In this event, charge the
12-volt battery. ( P.589)
In order to prevent the hybrid bat-
tery (traction batt ery) from becom-
ing extremely low in charge,
Charging ( P.94)

882-1. Plug-in hybrid system
Primarily using EV mode and
AUTO EV/HV mode when driv-
ing in cities and using HV mode
when driving on highways (or
freeways) can help conserve
fuel and electricity. (P.74)
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving fuel and
electricity economy. ( P.422)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within Eco area.
( P.158) Shift the shift position to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift position to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. In the N, the gasoline
engine operates but electricity
cannot be generated. Also,
when using the air conditioning
system, etc., the hybrid battery
(traction battery) power is con-
sumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration 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 con-
sumes hybrid battery (trac-
tion battery) po wer, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes

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.
