work properly or the danger that
it may work in situations where it
should not be working.
Installing electronic devices and
radios increases the risk of
cyber attacks through the
installed parts, which may lead
to unexpected accidents and
leakage of personal informa-
tion. Toyota does not make any
guarantees for problems caused
by installing non-genuine Toyota
products.
The installation of a mobile two-
way radio system in your vehicle
could affect electronic systems
such as:
Hybrid system
Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
Toyota Safety Sense 2.5
Anti-lock brake system
SRS airbag system
Seat belt pretensioner system
Be sure to check with your
Toyota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables on the Hybrid Electric Vehicles
emit approximately the same
amount of electromagnetic
waves as the conventional gas-
oline powered vehicles or home
electronic appliances despite of
their electromagnetic 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
cameras. Contact your
Toyota dealer for the location
of recording 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.

Your vehicle may transmit the data

Driving
objects that may contact your
vehicle, such as thick grass, tree
branches, or a banner
• When driving through steam or smoke
• When driving near an object that reflects radio waves, such as a
large truck or guardrail
• When driving near a TV tower, broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical
noise may be present
• When there are many things which can reflect the radio waves
of the radar in the vicinity (tunnels,
truss bridges, gravel roads, snow
covered road that have tracks,
etc.)
• While making a right/left turn, when an oncoming vehicle or a
crossing pedestrian has already
exited the path of your vehicle
• While making a right/left turn, closely in front of an oncoming
vehicle or a crossing pedestrian.
• While making a right/left turn, when an oncoming vehicle or a
crossing pedestrian stops before
entering the path of your vehicle
• While making a right/left turn,
when an oncoming vehicle turns
right/left in front of your vehicle
• While steering into the direction of oncoming traffic
■Situations in which the system
may not operate properly
●In some situations such as the fol-
lowing, an object may not be
detected by the radar sensor and
front camera, pre
venting the sys-
tem from opera ting properly:
• When a detectable object is
approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden
swerving, acceleration or deceler-
ation)
• When your vehicle approaches a detectable object rapidly
• When a detectable object is not
directly in front of your vehicle
• When a detectable object is near
a wall, fence, gua rdrail, manhole
cover, vehicle, steel plate on the
road, etc.
• When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as
large baggage, an umbrella, or
guardrail
• When there are many things which can reflect the radio waves
of the radar in the vicinity (tunnels,
truss bridges, gravel roads, snow
covered road that have tracks,
etc.)
• When there is an effect on the radio waves to the radar that is
installed on another vehicle
• When multiple det ectable objects
are close together
• If the sun or other light is shining
directly on a detectable object
