Vehicle control and operation data recording
Your Toyota is equipped with sophisticated computers that record certain
information about your vehicle’s operation, such as:
• Engine speed
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
The data recorded varies according to the grade level and options the vehi-
cle is equipped with. The computers do not record conversations, sound 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 research purposes where the data is not tied to a specific vehicle or vehicle owner
● Usage of date 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.

Event data recorder
Your vehicle has computers that monitor and control certain aspects of your
vehicle. These computers assist in driving and maintaining optimal vehicle
performance.
Besides storing data useful for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or near crash event.
The SRS airbag sensor assembly contains the EDR. In a crash or near crash
event, this device may record the following information:
• Engine speed
• Whether the brake pedal was depressed or not
• Vehicle speed
• To what extent the accelerator pedal was depressed
• The transaxle shift position
• Whether the driver and front passenger wore seat belts or not
• Driver’s seat position
• SRS airbag deployment data
• SRS airbag system diagnostic data
• Front passenger’s occupant classification
The information above is intended to be used for the purpose of improving
vehicle safety performance. Unlike general data recorders, the EDR does
not record sound data such as conversation between passengers.

●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 leasing company for a leased vehicle) is obtained
• In response to an official requested by the police, a court of law or a gov- ernment agency
• Necessary, for use as a defense for Toyota in a lawsuit
However, if necessary, Toyota may:
• Use the data for research on Toyota vehicle safety performance
• Disclose the data to a third party for research purposes without disclosing
details of the vehicle owner, and that only when deemed necessary
• Disclose summarized data cleared of vehicle identification information to a non-Toyota organization for research purposes
Scrapping of your Toyota
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.
Perchlorate Material
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbags, seat belt pretensioners, and wireless remote con-
trol batteries.

CAUTION
■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 dis-
tracts 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 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 themselves by playing with
the cigarette lighter, the windows, the moon roof, or other features of the
vehicle. In addition, heat build-up or ex tremely cold temperatures inside the
vehicle can be fatal to children.
