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.
