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 less ee 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 ex plosive 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/

sioners, wireless remote control

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 drivin g: 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 collision with resulting
death or serious injury to you,
your occupant s 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 them-
selves by playing with the side
windows, the moon roof or other
features of the vehicle. In addi-
tion, heat build-up or extremely
cold temperatures inside the vehi-
cle can be fatal to children.
