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

This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will
assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is
designed to record such data
as:
How various systems in your
vehicle were operating;
 Whether or not the driver and
passenger safety belts were
buckled/fastened;
 How far (if at all) the driver
was depressing the accelera-
tor and/or brake pedal; and,
 How fast the vehicle was trav-
eling.
These data can help provide a
better understanding of the cir-
cumstances in which crashes
and injuries occur.
NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions

and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the
EDR data with the type of per-
sonally identifying data rou-
tinely acquired during a crash
investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the
information if they have access
to the vehicle or the EDR.
Disclosure of the EDR data
Toyota will not disclose the data
recorded in an EDR to a third party
except when:
• An agreement from the vehicle’s
owner (or the less ee for a leased
vehicle) is obtained
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
However, if necessary, Toyota
may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes without
disclosing information about the
specific vehicle or vehicle owner
The SRS airbag and seat belt
pretensioner devices in your
Toyota contain ex plosive chemi-
cals. If the vehicle is scrapped
with the airbags and seat belt
pretensioners left as they are,
this may cause an accident such
as fire. Be sure to have the sys-
tems of the SRS airbag and seat
belt pretensioner removed and
disposed of by a qualified ser-
vice shop or by your Toyota
dealer before you scrap your
vehicle.
Special handling may apply,
See www.dtsc.ca.gov/

Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation 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 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 front seats,
parts of the front and rear pillars,
and roof side rails, may be hot for
several minutes. T he 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.86)
●All of the doors will be unlocked.
( P.134)
●The brakes and st op lights will be
controlled automatically. (
 P.335)
●The interior lights will turn on auto-
matically. ( P.365)
●The emergency flashers will turn
on automatically. ( P.456)
●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 attempt 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.75)
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.

■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of force corresponding
to an approximately 12 - 18 mph
[20 - 30 km/h] front al collision with
a fixed wall that d oes not move or
deform).
However, this thre shold velocity will
be considerably hig her in the follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform
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,
it is possible that only the seat belt
pretensioners will activate.
●The SRS front airbags for the front
passenger will not activate if there
is no passenger sitting in the front
passenger seat. However, the
SRS front airbags for the front
passenger may de ploy if luggage
is put in the seat, even if the seat
is unoccupied.
●The SRS seat cushion airbag on
the front passen ger seat will not
operate if the occupant is not
wearing a seat belt.
■SRS airbag deployment condi-
tions (SRS side and curtain
shield airbags)
●The SRS side and curtain shield
airbags will deploy i n the event of
an impact that exceeds the set
threshold level (the level of force
corresponding to the impact force
produced by an approximately
3300 lb. [1500 kg] vehicle colliding
with the vehicle cabin from a
direction perpendicular to the
vehicle orientation at an approxi- mate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags
may deploy in the event of a
severe side collision.
●Both SRS curtain shield airbags
will deploy in the e
vent of vehicle
rollover.
●Both SRS curtain shield airbags
may also deploy in the event of a
severe frontal collision.
■Conditions under which the
SRS airbags may deploy
(inflate), other t han a collision
The SRS front airbags and SRS cur-
tain shield airbag s may also deploy
if a serious impact occurs to the
underside of your vehicle. Some
examples are shown in the illustra-
tion.
●Hitting a curb, edge of pavement
or hard surface
●Falling into or jumping over a deep
hole
●Landing hard or falling
The SRS curtain shield airbags may
also deploy under the situations
shown in the illustration.
●The angle of vehicle tip-up is mar-
ginal.
●The vehicle skids and hits a curb
stone.

WARNING
●The SRS driver airbag deploys
with considerable force, and
can cause death or serious
injury especially i f the driver is
very close to the airbag. The
National Highway Traffic Safety
Administration (NHTSA)
advises:
Since the risk zone for the
driver’s airbag is the first 2 - 3
in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm)
from your driver airbag provides
you with a clear margin of
safety. This distance is mea-
sured from the center of the
steering wheel to your breast-
bone. If you sit less than 10 in.
(250 mm) away now, you can
change your driving position in
several ways:
• Move your seat to the rear as far as you can while still reach-
ing the pedals comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary,
many drivers can achieve the
10 in. (250 mm) distance, even
with the driver seat all the way
forward, simply by reclining the
back of the seat somewhat. If
reclining the back of your seat
makes it hard to see the road,
raise yourself by using a firm,
non-slippery cushion, or raise
the seat if your vehicle has that
feature.
• If your steering wheel is adjust- able, tilt it downward. This
points the airbag toward your
chest instead of your head and
neck.
The seat should be adjusted as
recommended by NHTSA above,
while still maintaining control of
the foot pedals, steering wheel,
and your view of the instrument
panel controls.
●If the seat belt extender has
been connected to the front
seat belt buckles but the seat
belt extender has not also been
fastened to the latch plate of the
seat belt, the SRS front airbags
will judge that the driver and
front passenger are wearing the
seat belt even though the seat
belt has not been connected. In
this case, the SRS front airbags
may not activate correctly in a
collision, resulting in death or
serious injury in the event of a
collision. Be su re to wear the
seat belt with the seat belt
extender.
●The SRS front passenger air-
bag also deploys with consider-
able force, and can cause death
or serious injury especially if the
front passenger is very close to
the airbag. The front passenger
seat should be as far from the
airbag as possible with the seat-
back adjusted, so the front pas-
senger sits upright.
●Improperly seated and/or
restrained infants and children
can be killed or seriously injured
by a deploying airbag. An infant
or child who is too small to use
a seat belt should be properly
secured using a child restraint
system. Toyota strongly recom-
mends that all infants and chil-
dren be placed in the rear seats
of the vehicle and properly
restrained. The rear seats are
safer for infants and children
than the front passenger seat.
