to subscribers. Safety Con-
nect is supported by
Toyota’s designated
response center, which
operates 24 hours per day, 7
days per week.
Safety Connect service is
available by subscription on
select, telematics hardware-
equipped vehicles.
By using the Safety Connect
service, you are agreeing to
be bound by the Telematics

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,

For safety and security
The following indicator light pat-
terns indicate specific system
usage conditions:
Green indicator light on =
Active service
 Green indicator light flashing
= Safety Connect call in pro-
cess
 Red indicator light (except at
vehicle start-up) = System
malfunction (contact your
Toyota dealer)
 No indicator light (off) =
Safety Connect service not
active
■Automatic Collision Notifi-
cation
In case of either airbag deploy-
ment or severe rear-end colli-
sion, the system is designed to
automatically call the response
center. The responding agent
receives the vehicle’s location
and attempts to speak with the
vehicle occupants to assess the
level of emergency. If the occu-
pants are unable to communi-
cate, the agent automatically
treats the call as an emergency,
contacts the nearest emer-
gency services provider to
describe the situation, and
requests that assistance be sent
to the location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety
Connect can work with local
authorities to assist them in
locating and recovering the
vehicle. After filing a police
report, call the Customer Experi-
ence Center at 1-800-331-4331
in the United States, 1-877-855-
8377 in Puerto Rico or 1-888-
869-6828 in Canada, and follow
the prompts for Safety Connect
to initiate this service.
In addition to assisting law
enforcement with recovery of a
stolen vehicle, Safety-Connect-
equipped vehicle location data
may, under certain circum-
stances, be shared with third
parties to locate your vehicle.
Further information is available
at Toyota.com in the United
States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
■Emergency Assistance But-
ton (“SOS”)
In the event of an emergency on
the road, push the “SOS” button
to reach the Safety Connect
response center. The answering
agent will determine your vehi-
cle’s location, assess the emer-
gency, and dispatch the
necessary assistance required.
If you accidentally press the “SOS”
button, tell the response-center
agent that you are not experiencing
an emergency.

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.

*: AWD models only
■When stopped/during start
off
The gasoline engine stops
*
when the vehicle is stopped.
During start off, the electric
motor (traction motor) drives the vehicle. At slow speeds or when
traveling down a gentle slope,
the engine is stopped
* and the
electric motor (traction motor) is
used.
When the shift lever is in N, the

Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics differ ent
from conventional vehicles. Be sure you are closely familiar
with the characteristics of your vehicle, and operate it with
care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.

is not being charged.
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P.80)
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).
■When braking (regenera-
tive braking)
The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.
■Regenerative braking
In the following si tuations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with the
recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released
while driving with the shift lever in
D or S.
●The brake pedal is depressed
while driving with the shift lever in
D or S.
■EV indicator
The EV indicator comes on when
the vehicle is driven using only the
electric motor (traction motor) or the
gasoline engine is stopped.
The on/off operation of the EV indi-
cator can be changed. ( P.112)
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it
may not stop automatically in the
following conditions
*:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the heater is switched on*: Depending on the circumstances, the gasoline engine may also not
stop automatically in other situa-
tions.
■Charging the hybrid battery
(traction battery)
As the gasoline engine charges the
hybrid battery (trac tion battery), the
battery does not need to be charged
from an outside source. However, if
the vehicle is left parked for a long
time the hybrid battery (traction bat-
tery) will slowly dis charge. For this
reason, be sure to drive the vehicle
at least once every few months for
at least 30 minutes or 10 miles (16
km). If the hybrid battery (traction
battery) becomes fully discharged
and you are unabl e to start the
