played on the multi-information dis-
play, EV driving (driving using only
the electric motor) may be canceled
and both gasoline engine and elec-
tric motor are used depending on
the situation (EV driving will be
returned to automatically 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 hill, 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.392)
●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.
■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.392)
*: Depending on the circumstances,
the gasoline engine may also not
stop automatically in situations
other than those above.

vibration even thoug h the vehicle is
able to move with the “READY” indi-
cator is illuminated. For safety,
apply the parking brake and make
sure to shift the shift lever to P when
parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion.
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
when the hybrid sy stem starts or
stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid ba ttery (traction
battery), behind the rear seats,

indicator came on, the power
switch can be turned to off without
any further action.)
When the 12-volt battery is dis-
charged, refer to P.534, “If the 12-
volt battery is discharged” and
perform the corr ection procedure.
●When the vehicle is left with the
AC charging cable connected, the
electricity consumption amount of
the 12-volt battery increases due
to controls, such as the system
checking, operating. When the AC
charging cable is not needed,
remove it from the vehicle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting Sy stem may be dif-
ficult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the Acoustic Vehicle Alert-
ing System is installed on the front
of the vehicle, it may be more diffi-
cult to hear from the rear of the vehi-
cle compared to the front.
■When “Acoustic V ehicle Alert-
ing System Malfunction Visit

detected by the impact sensor,
the emergency shut off system
blocks off the high voltage cur-
rent and stops the fuel pump to
minimize the risk of electrocu-
tion and fuel leakage.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the hybrid sys-
tem, contact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.
■If a warning light comes on, a
warning message is displayed
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
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.78)
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.372)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within Eco area.

The value displayed on the SOC
(State of Charge) gauge
(P.165) is estimated from the
following information.
The amount of hybrid battery
(traction battery) charge cur-
rently remaining
The electricity consumption
(the estimated distance that
EV driving is possible per unit
of electrical energy) based on
the recorded value
Past air conditioning system
electricity consumption
amount
The electricity consumption var-
ies depending on how the vehi-
cle is driven. The vehicle automatically records the elec-
tricity consumption when being
charged and uses the electricity
consumption for estimating the
EV driving range. Therefore, the
EV driving range displayed
when the hybrid battery (traction
battery) is fully charged may dif-
fer 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 con-
sumption based on the recorded
value is stable (for approxi-
mately the first month or two).
However, this does not indicate
a malfunction.
When the air conditioning sys-
tem is turned on, the EV driving
range (with using the air condi-
tioning system) is estimated
based on the past air condition-
ing electricity consumption
amount considering that the
electricity consumption may
become higher.
The distance that EV driving is
possible varies significantly
depending on how the vehicle is
driven, road conditions, the
weather, the outside tempera-
ture, usage conditions of electri-
cal components and the number
EV driving range
The EV driving range dis-
played on the multi-informa-
tion display shows the
reference distance that EV
driving (driving using only
the electric motor) is possi-
ble, and the actual distance
that can be driven may dif-
fer from that displayed.
Even if the EV driving range is
displayed, EV driving may be
canceled and both gasoline
engine and electric motor are
used depending on the situa-
tion. (

Tips for extending the EV
driving range
962-1. Plug-in hybrid system
of occupants.
The distance that EV driving is
possible can be extended if the
following is performed:
■When starting off, depress
the accelerator pedal
smoothly to accelerate
As a guide, accelerate up to
approximately 12mph (20 km/h)
in the first 5 seconds.
Electrical and fuel efficiency can
be improved just by using the
ECO Accelerator Guidance dis-
played on the multi-information
display and taking care to start
off gently. ( P.173)
When the driving mode is set to
Eco drive mode, depressing the
accelerator pedal generates
smooth torque that makes it easier
to operate the accelerator gently.
At the same time, the air condition-
ing control is switched to eco air
conditioning mode ( P.391) to
reduce the strength of the air condi-
tioning operation.
■Maintain sufficient vehicle-
to-vehicle distance and do
not accelerate or decelerate
unnecessarily
Try to maintain a fixed speed
while driving. Driving at a short
vehicle-to-vehicle distance will
result in repeating wasteful
acceleration and deceleration,
which will worsen the electrical
and fuel efficiency.
■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.167)
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 reac h the maximum
level and the upper limit of the
recoverable energy will be
exceeded. Theref ore, be sure to
operate the brak e pedal early.
■Use the air conditioning
system appropriately, and
also utilize the heated steer-
ing wheel (if equipped) and
seat heaters
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.
972-1. Plug-in hybrid system
2
Plug-in hybrid system
When eco air conditioning mode
is used, the air conditioning con-
trol is switched automatically to
a lower setting. (P.391)
The heated steering wheel (if
equipped) and seat heaters are
efficient heating device that
directly warm the body using
less electric power.
When used togethe r 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
affects electrical and fuel effi-
ciency. Remove any exterior
accessories such as a roof lug-
gage carrier when they are not
being used.
The running resistance of snow
tires is high and they will worsen
electrical and fuel efficiency.
Replace them with standard
tires as soon as they are no lon-
ger needed.
■Know your vehicle’s electri-
cal and fuel efficiency
If you know your vehicle’s daily
electrical and fuel efficiency, you
will understand the benefits of
Eco drive.
Use the Power Consump-
tion/Fuel Economy, ECO Accel-
erator Guidance/“Eco Score”
and other data displayed on the
multi-information display.
