The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
● Cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
Your Toyota is equipped with several sophisticated computers that will record
certain data, such as: • Engine speed
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
The recorded data varies according to the vehicle grade level and options
with which it is equipped. Furthermore, these computers do not record con-
versations, sounds or pictures.
●Data usage
Toyota may use the data recorded in these computers to diagnose malfunc-
tions, 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 govern- ment agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
●Usage of data collected through Safety Connect (U.S. mainland only)
If your Toyota has Safety Connect and if you have subscribed to those ser-
vices, please refer to the Safety Connect Telematics Subscription Service
Agreement for information on data collected and its usage.

SIENNA_OM_OM08013U_(U)This vehicle is equipped with an event data recorder (EDR). The main pur-
pose 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 seconds 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/fas- tened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a nontrivial crash situa-
tion 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. However, other parties, such as law enforcement, could combine
the EDR data with the type of personally identifying data routinely 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 manufacturer,
other parties, such as law enforcement, that have the special 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 vehi- cle) is obtained
• In response to an official request by the police, a court of law or a govern- ment 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 chemicals. 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 systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service 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 compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

WARNING
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, 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. Anything that
distracts 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.
■ General precaution regard ing 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 themselves by playing with
the cigarette lighter, the windows, the 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.
