Approximately five hours after
the hybrid system is turned off, you may hear sound coming
from under the vehicle for sev-
eral minutes. This is the sound
of a fuel evaporation leakage
check and, it does not indicate a
malfunction.
A wide variety of non-genuine
spare parts and accessories for
Toyota vehicles are currently
available in the market. You
should know that Toyota does
not warrant these products and
is not responsible for their per-
formance, repair, or replace-
ment, or for any damage they
may cause to, or adverse effect
they may have on, your Toyota
vehicle.
This vehicle should not be modi-
fied with non-genuine Toyota
products. Modification with non-
genuine Toyota products could
affect its performance, safety or
durability, and may even violate
governmental regulations. In
addition, damage or perfor-
mance problems resulting from
the modification may not be cov-
ered under warranty.
Also, remodeling like this will
have an effect on advanced
safety equipment such as
Toyota Safety Sense 3.0 and
there is a danger that it will not

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 3.0
 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.
This vehicle is equipped with
sophisticated computers that
record certain data regarding
vehicle controls and operations.

371-1. For safe use
1
For safety and security
bag sensor assembly (ECU) controls airbag deployment based on
information obtained from the sensors, etc., shown in the system
components diagram above. This information includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed of deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the parts
around the airbags may be hot for
several minutes. The airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. (P.87)
●The brakes and st op lights will be
controlled automatically.
(  P.425)
●The interior lights will turn on auto-
matically. ( P.446)
●The emergency flashers will turn
on automatically. ( P.546)
●For Safety Connect subscribers, if
any of the following situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will a ttempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency services. (
P.65)
• When an SRS airbag has been deployed
• When a seat belt pretensioner has
operated
• When the vehicle has been involved in a severe rear-end colli-
sion
■The SRS airbags deploy in a
frontal impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds a threshold level
(level of force corresponding to an
approximately 12 - 18 mph [20 -
30 km/h] frontal collision with a
fixed wall that does not move or
deform):
• SRS front airbags
●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle underrides, or goes under, the
bed of a truck
●Depending on the type of collision,
only the following may deploy:
• Seat belt pretensioners
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passenger in the front
passenger seat. However, the
SRS airbags for the front passen-
ger’s seat may deploy, even if the
seat is unoccupied, if luggage is
put on the seat.

681-3. Emergency assistance
■Enhanced Roadside Assis-
tance
Enhanced Roadside Assistance
adds GPS data to the already
included warranty-based Toyota
roadside service.
Subscribers can press the
“SOS” button to reach a Safety
Connect response-center agent,
who can help with a wide range
of needs, such as: towing, flat
tire, fuel delivery, etc. For a
description of the Enhanced
Roadside Assistance services
and their limitations, please see
the Safety Connect Terms and
Conditions, which are available
at Toyota.com in the United
States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
Important! Read this informa-
tion before using Safety Con-
nect.
■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.

(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
