work properly or the danger that
it may work in situations where it
should not be working.
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 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 hybrid 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

■Exposure to radio fre-
quency signals
The Safety Connect system
installed in your vehicle is a
low-power radio transmitter and
receiver. It receives and also
sends out radio frequency (RF)
signals.
In August 1996, the Federal
Communications Commission
(FCC) adopted RF exposure
guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with
the safety standards previously
set by the following U.S. and
international standards bodies.

ANSI (American National
Standards Institute) C95.1
[1992]
 NCRP (National Council on
Radiation Protection and
Measurement) Report 86
[1986]
 ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.

vehicle is on a level surface. This
value may vary when the vehicle is
on a slope. Add extra fuel when the
vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
hybrid vehicles incorporate elec-
tromagnetic shielding, and there-
fore emit approximately the same
amount of electromagnetic waves
as conventional gasoline pow-
ered vehicles or home electronic
appliances.
●Your vehicle may cause sound
interference in some third
party-produced radio parts.
■Hybrid battery (tr action battery)
The hybrid battery (traction battery)
has a limited service life. The lifes-
pan of the hybrid battery (traction
battery) can change in accordance
with driving style and driving condi-
tions.
WARNING
■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a
12-volt system. DC and AC high
voltage is very dangerous and
can cause severe burns and elec-
tric shock that may result in death
or serious injury.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the warning labels
attached to the vehicle.
●Never try to open the service
plug access hole located under
the second seat. The service
plug is used only when the vehi-
cle is serviced and is subject to
high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Pull your vehicle off the road,
shift the shift le ver to P, apply
the parking brake, and turn the
hybrid system off.
●Do not touch the high voltage
parts, cables and connectors.
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●If a fluid leak occurs, do not
touch the fluid as it may be
strong alkaline electrolyte from
the hybrid battery (traction bat-
tery). If it comes into contact
with your skin or eyes, wash it
off immediately with a large
amount of water or, if possible,
boric acid solution. Seek imme-
diate medical attention.
●If a fire occurs in the hybrid
vehicle, leave the vehicle as
soon as possible. Never use a
fire extinguisher that is not
meant for electric fires. Using
even a small amount of water
may be dangerous.

■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following
cases:
• The electronic key is too close to the window or outside door han-
dle, near the ground, or in a high
place when the doors are locked
or unlocked.
• The electronic key is on the instru-
ment panel, luggage compart-
ment, floor, or in the door pockets
or glove box when the hybrid sys-
tem is started or power switch
modes are changed.
●Do not leave the electronic key on
top of the instrument panel or near
the door pockets when exiting the
vehicle. Depending on the radio
wave reception conditions, it may
be detected by the antenna out- side the cabin and the door will
become lockable from the outside,
possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is
within the effective range, the
doors may be locked or unlocked
by anyone. However, only the
doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electro
nic key is not
inside the vehicle, it may be possi-
ble to start the hybrid system if the
electronic key is near the window.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash when the
electronic key is within the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possib ility that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective range, the door may
lock and unlock repeatedly. In that
case, follow the following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to bat-
