SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury to the
occupants. They work together with the seat belts to help reduce the
risk of death or serious injury.
SRS front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front pas-
senger from impact with interior components
SRS knee airbag
Can help provide driver protection

Before driving
PRIUS +_OM_OM47821E_(EE)The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. 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 occu-
pants.
If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
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.
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 approxi-
mately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle and sign pole, which can move
or deform on impact, or if the vehicle is involved in an underride collision
(e.g. a collision in which the front of the vehicle “underrides”, or goes
under, the bed of a truck, etc.).
Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.

SRS airbag deployment conditions (SRS side and curtain shield air-
bags)
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 1500 kg [3300 lb.] vehicle collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orien-
tation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
Conditions under which the SRS airbags may deploy (inflate), other
than a collision
The SRS front airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some examples are shown in the illustration.
Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the SRS front airbags may occur.
Hitting a curb, edge of pavement or
hard surface
Falling into or jumping over a deep hole
Landing hard or falling
Collision from the side
Collision from the rear
Vehicle rollover

Types of collisions that may not deploy the SRS airbags
(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
The SRS side and curtain shield airbags do not generally inflate if the vehi-
cle is involved in a frontal or rear collision, if it rolls over, or if it is involved in
a low-speed side collision.
When to contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional
In the following cases, contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional as soon as possible.
Any of the SRS airbags has been inflated.
Collision from the side to the vehicle
body other than the passenger com-
partment
Collision from the side at an angle
Collision from the front
Collision from the rear
Vehicle rollover

164 1-8. Safety information
PRIUS +_OM_OM47821E_(EE)
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 airbags to inflate.
A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side and cur-
tain 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 surface of the seats with the side
airbag is scratched, cracked, or other-
wise damaged.
The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain shield airbags
inside is scratched, cracked, or other-
wise damaged.

CAUTION
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.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.)
of inflation, placing yourself 250 mm (10 in.) 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 250
mm (10 in.) 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
pedals comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm
(10 in.) 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 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 above, while still maintaining
control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

CAUTION
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. 173)

CAUTION
SRS airbag precautions
Do not sit on the edge of the seat or
lean against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
Do not allow the front seat occupants to
hold items on their knees.
Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
