For your infor mation
Please note that this manual applies to all models and explains all equipment,
including options. Therefore, you may find some explanations for equipment
not installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Toyota policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Approximately five hours after the hybrid system is turned off, you may hear
sound coming from under the vehicle for several minutes. This is the sound of
a fuel evaporation leakage check and, it does not indicate a malfunction.
A wide variety of non-genuine spare parts and accessories for Toyota vehi-
cles are currently available in the market. You should know that Toyota does
not warrant these products and is not responsible for their performance,
repair, or replacement, or for any damage they may cause to, or adverse
effect they may have on, your Toyota vehicle.
This vehicle should not be modified with non-genuine Toyota products. Modi-
fication with non-genuine Toyota products could affect its performance, safety
or durability, and may even violate governmental regulations. In addition,
damage or performance problems resulting from the modification may not be
covered under warranty.

The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●Hybrid system
●Multiport fuel injection system/sequential multiport fuel injection system
●Toyota Safety Sense 2.0
●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.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

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 non-trivial crash situ-
ation occurs; no data are recorded by the EDR under normal driving 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 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

●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
