Be sure to check with your Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables
on the fuel cell vehicles emit
approximately the same amount
of electromagnetic waves as the
conventional gasoline powered
vehicles or home electronic
appliances despite of their elec-
tromagnetic shielding.
Unwanted noise may occur in
the reception of the mobile two-
way radio.
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 cameras
Your vehicle is equipped with cam-
eras. Contact your Toyota dealer for
the location of re cording cameras.
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.
Data usage
Toyota may use the data recorded
in this computer to diagnose mal-
functions, conduct research and
development, and improve quality.
Toyota will not disclose the
recorded data to a third party
except:
• With the consen t 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
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehi-
cle or vehicle owner
 Recorded image information
can be erased by your Toyota
dealer.
The image recording function can
be disabled. However, if the func-
tion is disabled, data from when the
system operates will not be avail-
able.

pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When parking the vehicle
Always set the parking brake, and
shift the shift position to P. Failure

●Short in electrical components
●Fuel cell system damage
caused by water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toy-
ota dealer check the following:
●Fuel cell system
●Brake function
●Changes in quantity and quality
of transmission fluid, etc.
