could affect electronic systems
such as:
Hybrid system
 Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 2.0
 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 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
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.
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 consen t 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 is not tied to a specific vehi-
cle or vehicle owner
 Recorded image information
can be erased by your Toyota

dealer.
The image recording function can
be disabled. However, if the func-
tion is disabled, data from when the
system operates will not be avail-
able.

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.
To read data recorded by an
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 for 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/
hazardouswaste/perchlorate.
Your vehicle has components
that may contain perchlorate.
These components may include
the airbags, seat belt preten-
sioners, wireless remote control
batteries, and the batteries in
the tire pressure warning valve
and transmitters.

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 distrac ts the driver,
such as adjusting controls, talking
on a cellular phone or reading can
result in a collision with resulting
death or serious injury to you,
your occupants or others.
