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

For safety and security
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 and knee airbags
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.
■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 event 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
side and curtain shield airbags may
also deploy if a serious impact
occurs to the underside of your vehi-
cle. Some examples are shown in
the illustration.
●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.
■Types of collisions that may not
deploy the SRS airbags (SRS
front airbags)
The SRS front airbags do not gener-
ally inflate if the vehicle is involved
in a side or r ear collision, if it rolls
over, or if it is involved in a low-
speed frontal collision. But, when-
ever a collision o f any type causes
sufficient forward deceleration of the
vehicle, deploym ent of the SRS
front airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover

701-3. Emergency assistance
Owners Manual_USA_M0C052_en
When the power switch is turned
to ON, the red indicator light
comes on for 2 seconds then
turns off. Afterward, the green
indicator light comes on, indicat-
ing that the service is active.
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 Toy-
ota 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 Safety Connect
response 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.
■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 answer-
ing agent will determine your
vehicle’s location, assess the
emergency, and dispatch the

■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, the communication between
the electronic key and the vehicle
may be affected, preventing the
smart key system, wireless remote
control and immobilizer system from
operating properly. (Ways of coping:
 P.527)
●When the electronic key battery is
depleted
●Near a TV tower, electric power
plant, gas station , radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
●When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●When the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• Cigarette boxes that have alumi- num foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Another electronic key or a wire- less key that emits radio waves
• Personal computers or personal
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted.
■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 near the
ground or in a high place, or too
close to the center of the rear
bumper.
• The electronic key is on the instru- ment panel, or floor, or in the door
pockets or glove box when the
hybrid system 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 doors 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
