For safe driving
Adjust the angle of the seat-
back so that you are sitting
straight up and so that you do
not have to lean forward to
steer. (P. 3 0 1 )
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel. (P. 301)
Lock the head restraint in place with the center of the head restraint
closest to the top of your ears. (P. 3 0 5 )
Wear the seat belt correctly. (P. 3 0 )
Make sure that all occupants are wearing their seat belts before driv-
ing the vehicle. (P. 3 0 )
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt.
(P. 58)
Make sure that you can see backward clearly by adjusting the inside
and outside rear view mirrors properly. (P. 310, 312)

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-

• 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.

WARNING
■SRS airbag precautions
●Do not hang coat hangers or other hard objects on the coat hooks. All of
these items could become projectiles and may cause death or serious
injury, should the SRS curtain shield airbags deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy,
be sure to remove it.
●Do not use seat accessories which cover the parts where the SRS side
airbags and SRS seat cushion airbag inflate as they may interfere with
inflation of the SRS airbags. Such accessories may prevent the side air-
bags and seat cushion airbag from activating correctly, disable the system
or cause the side airbags and seat cushion airbag to inflate accidentally,
resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS air-
bag components or the front doors.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
●Do not attach anything to areas such as
a door, windshield, side windows, front
or rear pillar, roof side rail and assist
grip.

WARNING
■SRS airbag precautions
●If breathing becomes difficult after the SRS airbags have deployed, open a
door or side window to allow fresh air in, or leave the vehicle if it is safe to
do so. Wash off any residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
●Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front

■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
●<002c0051005600570044004f004f00440057004c00520051000f0003005500480050005200590044004f000f00030047004c0056004400560056004800500045004f005c000300440051004700030055004800530044004c00550003005200490003005700

■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.

PRIUS PRIME_OM_OM47D71U_(U)■When to contact your Toyota dealer
In the following cases, the vehicle will require inspection and/or repair. Con-
tact your Toyota dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS front airbags to inflate.
●A portion of a door or its surrounding
area is damaged, deformed or has had a
hole made in it, or the vehicle was
involved in an accident that was not
severe enough to cause the SRS side
and curtain shield airbags to inflate.
●The pad section of the steering wheel,
dashboard near the front passenger air-
bag or lower portion of the driver’s side
instrument panel is scratched, cracked,
or otherwise damaged.
●The front passenger’s seat cushion sur-
face is scratched, cracked, or otherwise
damaged.
