This vehicle is equipped with an event data recorder (EDR). The main pur-
pose 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 seconds 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/fas-
tened;
• How far (if at all) the driver was depressing the accelerator and/or brake
pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situ-
ation occurs; no data are recorded by the EDR under normal driving condi-
tions and no personal data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforcement, could combine
the EDR data with the type of personally identifying data routinely 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 manufacturer,
other parties, such as law enforcement, that have the special equipment, can

cle) is obtained
• In response to an official request by the police, a court of law or a govern-
ment agency
• For use by Toyota in a lawsuit

WARNING
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
●<00320051004f005c000300580056004800030049004f005200520055000300500044005700560003004700480056004c004a005100480047000300490052005500030057004b0048000300470055004c00590048005500b600560003005600480044005700

●Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
●With the hybrid system stopped and the
shift position in P, fully depress each
pedal to the floor to make sure it does
not interfere with the floor mat.

For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This information includes crash severity 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.
WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if 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 pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. 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 reaching the ped-
als 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-
<0056004f004c0053005300480055005c0003004600580056004b004c00520051000f000300520055000300550044004c0056004800030057004b0048000300560048004400570003004c00490003005c005200580055000300590048004b004c0046004f00

• If your steering wheel is adjustable, tilt it downward. This points the air-
bag 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.

PRIUS PRIME_OM_OM47D71U_(U)
WARNING
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable 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 air-
bag as possible with the seatback adjusted, so the front passenger 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 sys-
tem. Toyota strongly recommends that all infants and children 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. (P. 58)
●If the seat belt extender has been con-
nected 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 sure to wear the
seat belt with the seat belt extender.

■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 (steering 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. 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. 99)
●The emergency flashers will turn on automatically. (P. 664)
●For Safety Connect subscribers, if any of the following situations occur, the
system is designed to send an emergency call to the response center, noti-
fying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak with the occupants to ascertain the
level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emergency and

• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment conditions (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] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
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 collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
●Depending on the type of collision, it is possible that only the seat belt pre-
tensioners and seat cushion airbag 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 air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
●The SRS seat cushion airbag on the front passenger seat will not operate if
the occupant is not wearing a seat belt.

For safety and security
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags will deploy in 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 approximate speed of 12 - 18 mph [20 - 30 km/h]).
●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 than
a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a
serious impact occurs to the underside of your vehicle. Some examples are
shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations 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 angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.
