501-2. Child safety
1-2.Child safety
Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the shift lever, wiper
switch, etc.
 Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.189, 229)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
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 ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.

■Safety Connect Services Infor-
mation
●Phone calls using the vehicle’s
Bluetooth® technology will not be
possible when Safety Connect is
active and in use.
●Safety Connect is available begin-
ning Fall 2009 on select Toyota
models (in the contiguous United
States only). Contact with the
Safety Connect response center
is dependent upon the telematics
device being in operative condi-
tion, cellular connection availabil-
ity, and GPS satellite signal
reception, which can limit the abil-
ity to reach the response center or
receive emergency service sup-
port. Enrollment and Telematics
Subscription Service Agreement
are required. A variety of subscrip-
tion terms are available; charges vary by subscripti
on term selected
and location.
●Automatic Collision Notification,
Emergency Assistance and Stolen
Vehicle Location are available in
the United States, including
Hawaii and Alaska, Puerto Rico
and Canada, and Enhanced
Roadside Assistance are avail-
able in the United States, Puerto
Rico and Canada.
●Automatic Collision Notification,
Emergency Assistance, Stolen
Vehicle and Enhanced Road
Assistance are not available in the
U.S. Virgin Islands.
For vehicles first sold in the U.S.
Virgin Islands, no Safety Connect
services will function in or outside

■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.

1-4.Theft deterrent system
The indicator light flashes after
the power switch has been
turned to off to indicate that the
system is operating.
The indicator light stops flashing
after the power switch has been
turned to ACC or ON to indicate
that the system has been can-
celed.
■System maintenance
The vehicle has a maintenance-free
type immobilizer system.
■Conditions that may cause the
system to malfunction
●If the grip portion of the key is in
contact with a metallic object
●If the key is in close proximity to or
touching a key to the security sys-
tem (key with a built-in transpon-
der chip) of another vehicle
Immobilizer system
The vehicle’s keys have
built-in transponder chips
that prevent the hybrid sys-
tem from starting if a key
has not been previously
registered in the vehicle’s
on-board computer.
Never leave the keys inside
the vehicle when you leave
the vehicle.
This system is designed to
help prevent vehicle theft but
does not guarantee absolute
security against all vehicle
thefts.
Operating the system
NOTICE
■To ensure the system oper-
ates correctly
Do not modify or remove the sys-
tem. If modified or removed, the
proper operation of the system
cannot be guaranteed.

Plug-in hybrid system features
The plug-in hybrid system is a system excellent in both eco-
nomical efficiency of electric vehicles and practicality of Plug-
in Hybrid Electric Vehicles
 EV driving can be performed using electricity charged from an
external power source.
*
If the amount of electricity remaining in the hybrid battery (trac-
tion battery) becomes low, the ve hicle is automatically controlled
in such a way that it can be driven as a Plug-in Hybrid Electric
Vehicle through the joint use of the gasoline engine.
*: The EV driving range will vary in a ccordance with conditions such as
vehicle speed, the amount of charge remaining in the hybrid battery
(traction battery) and the usage of the air conditioning system. The gas-
oline engine may also be used simultaneously in accordance with driv-
ing conditions.

Plug-in hybrid system
The plug-in hybrid system oper-
ates in the following modes.
The meter display can be used to
check which mode the plug-in
hybrid system is currently being
driven in. (P.150)
■EV mode
When a sufficient amount of
electricity is remaining after
charging
*1, EV driving is per-
formed using electricity stored in
the hybrid battery (traction bat-
tery).
*2
When in EV mode, the EV drive
mode indicator illuminates.
*1: The amount of remaining charge can be checked on the SOC
(State of Charge) gauge.
( P.155)
*2: Depending on the situation, EV
driving may be canceled and
both gasoline engine and electric
motor are used. ( P.79)
■AUTO EV/HV mode
Normally, the electricity stored
in the hybrid battery (traction
battery) is used for EV driving.
However, when more power is
required, such as for driving
uphill or accelerating suddenly,
the gasoline engine starts and
provides powerful acceleration
by strongly depressing the
accelerator pedal.
When the vehicle is in a condi-
tion where EV driving is possi-
ble, EV mode and AUTO EV/HV
mode can be switched by oper-
ating the switch. ( P.74)
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
■HV mode
When in HV mode, the vehicle is
driven using both the gasoline
Plug-in hybrid system
operation mode

742-1. Plug-in hybrid system
engine and electric motor.
(P.77)
• If electricity needed for EV driving in EV mode or AUTO
EV/HV mode is not remaining,
the operation mode will be
automatically switched to HV
mode.
• The operation mode can be switched to HV mode at any
timing by operating the switch
to keep electricity for EV driv-
ing etc. ( P.74).
* Switching
to HV mode when driving on a
highway or when driving uphill
is recommended in order to
conserve battery power.
When in HV mode, the HV drive
mode indicator illuminates.
*: The EV driving range may reduce even after switching to HV mode.
■Hybrid battery (traction bat-
tery) charge mode ( P.75)
Electricity generated by the gas-
oline engine can be used to
charge the hybrid battery (trac-
tion battery) by switching to the
hybrid battery (traction battery)
charge mode when electricity
needed for EV driving is not remaining.
*
• The system may not be able
to switch to the hybrid battery
(traction battery) charge
mode due to the state of the
plug-in hybrid system.
( P.76)
• Charging time differs depend- ing on the driving state of the
vehicle when driving in hybrid
battery (traction battery)
charge mode.
When in the hybrid battery (traction
battery) charge mode, the hybrid
battery charge mode indicator illu-
minates.
*: When in the hybrid battery (trac-tion battery) charge mode, the
hybrid battery can be charged
while driving. However, the gaso-
line engine runs to charge the
battery and fuel consumption
becomes higher compared with
driving in HV mode.
The plug-in hybrid system oper-
ation modes can be switched
using the switches.
■Switching the plug-in
hybrid system operation

switch or EV/HV mode selection
