Please note that this manual
applies to explains all models
and all equipment, including
options. Therefore, you may find
some explanations for equip-
ment not installed on your vehi-
cle.
All specifications provided in this
manual are current at the time of
printing. However, because of
the Toyota policy of continual
product improvement, we
reserve the right to make
changes at any time without
notice.
Depending on specifications,
the vehicle shown in the illustra-
tions may differ from your vehi-
cle in terms of color and
equipment.
Approximately five hours after
the hybrid system is turned off,
you may hear sound coming
from under the vehicle for sev-
eral minutes. This is the sound
of a fuel evaporation leakage
check and, it does not indicate a
malfunction.A wide variety of non-genuine
spare parts and accessories for
Toyota vehicles are currently
available in the market. You
should know that Toyota does
not warrant these products and
is not responsible for their per-
formance, repair, or replace-
ment, or for any damage they
may cause to, or adverse effect
they may have on, your Toyota
vehicle.
This vehicle should not be modi-
fied with non-genuine Toyota
products. Modification with
non-genuine Toyota products
could affect its performance,
safety or durability, and may
even violate governmental regu-
lations. In addition, damage or
performance problems resulting
from the modification may not
be covered under warranty.
Also, remodeling like this will
have an effect on advanced
safety equipment such as Toy-
ota Safety Sense 2.5 + and
there is a danger that it will not
work properly or the danger that
it may work in situations where it
should not be working.

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 Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables
on the hybrid vehicles emit
approximately the same amount
of electromagnetic waves as the
conventional gasoline powered
vehicles or home electronic
appliances despite of their elec-
tromagnetic 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 cam-
eras. 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.
These computers do not record
conversations or sounds, and
only record images outside of
the vehicle in certain situations.
 Data Transmission
Your vehicle may transmit the data
recorded in these computers to
Toyota without notification to you.
Data usage
Toyota may use the data recorded
in this computer to diagnose mal-
functions, conduct research and
development, and improve quality.
Toyota will not disclose the
recorded data to a third party
except:
• With the consent of the vehicle
owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the

data collected, used and shared
by Toyota, please visit

.
This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is
designed to record such data
as:
• How various systems in your
vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
• How far (if at all) the driver was depressing the accelera-
tor and/or brake pedal; and,
• How fast the vehicle was trav- eling.
These data can help provide a
better understanding of the cir-
cumstances in which crashes
and injuries occur.
NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions
and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the
EDR data with the type of per-
sonally identifying data rou-
tinely acquired during a crash
investigation.

EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the
information if they have access
to the vehicle or the EDR.
Disclosure of the EDR data
Toyota will not disclose the data
recorded in an EDR to a third party
except when:
• An agreement from the vehicle’s
owner (or the lessee for a leased
vehicle) is obtained
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
However, if necessary, Toyota may:
• Use the data fo r research on
vehicle safety performance
• Disclose the data to a third party for research purposes without
disclosing information about the
specific vehicle or vehicle owner
The SRS airbag and seat belt
pretensioner devices in your
Toyota contain explosive chemi-
cals. If the vehicle is scrapped
with the airbags and seat belt
pretensioners left as they are,
this may cause an accident such
as fire. Be sure to have the sys-
tems of the SRS airbag and seat
belt pretensioner removed and disposed of by a qualified ser-
vice shop or by your Toyota
dealer before you scrap your
vehicle.
Special handling may apply, See
www.dtsc.ca.gov/hazard-
ouswaste/perchlorate.
Your vehicle has components
that may contain perchlorate.
These components may include
airbag, seat belt pretensioners,
and wireless remote control bat-
teries.

WARNING
■General precautions while
driving
Driving under the influence: Never
drive your vehicle when under the
influence of alcohol or drugs that
have impaired your ability to oper-
ate your vehicle. Alcohol and cer-
tain drugs delay reaction time,
impair judgment and reduce coor-
dination, which could lead to an
accident that could result in death
or serious injury.
Defensive driving: Always drive
defensively. Anticipate mistakes
that other drivers or pedestrians
might make and be ready to avoid
accidents.
Driver distraction: Always give
your full attention to driving. Any-
thing that distracts the driver, such
as adjusting controls, talking on a
cellular phone or reading can
result in a collisio n with resulting
death or serious injury to you,
your occupants or others.

WARNING
■General precaution regarding
children’s safety
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children may injure them-
selves by playing with the win-
dows, the moon roof or panoramic
moon roof, or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.
