The installation of an RF-transmitter system in your vehicle could affect elec-
tronic systems such as:
●Hybrid system
●Multiport fuel injection system/sequential multiport fuel injection system
●Toyota Safety Sense
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer for precautionary measures or special
instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna posi-
tions and installation provisions for the installation of RF-transmitters, is avail-
able on request at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
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 radio frequency transmitter
(RF-transmitter).

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
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level, options and
destinations 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 usage
Toyota may use the data recorded in this computer 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 use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or
vehicle owner
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 any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer, before
you scrap your vehicle.

WARNING
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impair ed 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
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 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 windows, or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.
