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
● Toyota Safety Sense P (if equipped)
● Dynamic radar cruise control system (if equipped)
● Cruise control system (if equipped)
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary meas ures or spe-
cial instructions regarding instal lation of a mobile two-way radio system.
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 front camera (available only when certain safe ty sys-
tems are activated, which varies depending on the vehicle specifica-
tions).
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.

Vehicle data recording

11
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-lik e 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 circu mstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a non-trivi al crash situ-
ation occurs; no data are recorded by the EDR under normal driv ing condi-
tions 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 routi nely 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 e quipment, 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 lea sed vehi-
cle) is obtained
• In response to an official request by the police, a court of l aw 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 witho ut disclosing
information about the specific vehicle or vehicle owner
