work properly or the danger that
it may work in situations where it
should not be working.
Installing electronic devices and
radios increases the risk of
cyber attacks through the
installed parts, which may lead
to unexpected accidents and
leakage of personal informa-
tion. Toyota does not make any
guarantees for problems caused
by installing non-genuine Toyota
products.
The installation of a mobile two-
way radio system in your vehicle
could affect electronic systems
such as:
Hybrid system
 Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 2.5 +
 Anti-lock brake system
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your
Toyota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables on the Plug-in Hybrid Electric
Vehicles emit approximately the
same amount of electromag-
netic waves as the conventional
gasoline powered vehicles or
home electronic appliances
despite of their electromagnetic
shielding.
Unwanted noise may occur in
the reception of the mobile two-
way radio.
The vehicle is equipped with
sophisticated computers that will
record certain data, such as:
• Engine speed/ Electric motor
speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras Your vehicle is equipped with
cameras. Contact your
Toyota dealer for the location
of recording cameras.
The recorded data varies
according to the vehicle grade
level and options with which it is
equipped.

Plug-in hybrid system
The plug-in hybrid system oper-
ates in the following modes.
The multi-information display can
be used to check which mode the
plug-in hybrid system is currently
being driven in. (P.185, 196)
■EV mode
When a sufficient amount of
electricity is remaining after
charging
*1, EV driving is per-
formed using electricity stored in
the hybrid battery (traction bat-
tery).
*2
When in EV mode, the EV drive
mode indicator illuminates.
*1: The amount of remaining charge can be checked on the SOC
(State of Charge) gauge.
( P.173)
*2: Depending on the situation, EV
driving may be canceled and
both gasoline engine and electric
motor are used. ( P.80)
■AUTO EV/HV mode
Normally, the electricity stored
in the hybrid battery (traction
battery) is used for EV driving.
However, when more power is
required, such as for driving
uphill or accelerating suddenly,
the gasoline engine starts and
provides powerful acceleration
by strongly depressing the
accelerator pedal.
When the vehicle is in a condi-
tion where EV driving is possi-
ble, EV mode and AUTO EV/HV
mode can be switched by oper-
ating the switch. ( P.76)
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
■HV mode
When in HV mode, the vehicle is
driven using both the gasoline
Plug-in hybrid system

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.80). 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 multi-informa-
tion display. ( P.173, 178)
■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.80)
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 th e multi-informa-
tion display. ( P.173, 178)
■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).

822-1. Plug-in hybrid system
●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 dep ressed or as
the accelerator pedal is released.
●Vibration may be felt when the
gasoline engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vent under the
rear seat. ( P.89)
●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.114)
■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 t he 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 ra
nge will become
shorter.
■Refilling fuel
Plug-in Hybrid Electric Vehicles can
be driven using electricity charged
from an external power source.
However, as the ga soline engine is
used depending on the situation
(  P.80) 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 a mount and refill
immediately when the fuel level
becomes low. ( P.332)
■If the vehicle is not used for a
long time
●The 12-volt battery may dis-
charge. In this e vent, charge the
12-volt battery. ( P.569)
In order to prevent the hybrid bat-
tery (traction batt ery) from becom-
ing extremely low in charge,
charge the hybrid battery (traction
battery) from external power
source or start th e hybrid system
Charging (P.97)

at least once every 2 or 3 months,
and turn the power switch off after
the gasoline engine has stopped
automatically. (If the gasoline
engine does not start up even
after approximately 10 seconds
have passed since the “READY”
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.569, “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
your Dealer” is displayed on the
multi-information display
The Acoustic Vehicle Alerting Sys-
tem may be malf unctioning. Have
the vehicle inspected by your
Toyota dealer immediately.
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “MULTIME-
DIA OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the refer-
ence operation range ( ) of
the ECO Accelerator Guid-
ance ( P.187) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.

Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever 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) power, 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,
