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.
Front airbags
Driver airbag/front passenger airbag
Can help protect the head and ches t of the driver and front pas-
senger from impact with interior components.
Side and curtain shield airbags
Side airbag (if equipped)
Can help protect the torso of th e front occupants and rear out-
board occupants.
Curtain shield airbag (if equipped)
Can help protect primarily the head of front occupants and rear
outboard occupants.

Your vehicle is equipped with “ADVANCED AIRBAGS” designed
based on US motor vehicle safety standards (FMVSS208). The air-
bag system controls air
bag deployment power for the driver and front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants.
■ 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 seats, and parts of the front and rear pillars and roof side
rail, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.

PRIUS_U_(L/O_0802)
■Operating conditions (front airbags)
● The SRS front airbags will deploy if the severity of the frontal impact is
above the designed threshold level, comparable to an approximate 15
mph (25 km/h) collision, when the vehicle impacts straight into a fixed
barrier 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 or 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.).
● It is possible that in some collisions where the forward deceleration of the
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
● The SRS front passenger airbags will not activate, if there is no passen-
ger sitting in the front passenger seat. However, the front passenger air-
bag may deploy, if heavy luggage is put, even if the seat is unoccupied.
(P. 101)
■ Operating conditions (side and curt ain shield airbags [if equipped])
● The SRS side airbags and curtain shield airbags are designed to inflate
when the passenger compartment is subjected to a severe impact from
the side.
● The SRS front side airbag on the passenger seat will not activate, if there
is no passenger sitting in the front passenger seat. However, the front
side airbag on the passenger seat may deploy, if heavy luggage is put,
even if the seat is unoccupied. ( P. 101)

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 de ploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to 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 suffi-
cient forward deceleration of the vehicle, deployment of the SRS front air-
bags may occur.
● Hitting a curb, edge of pavement or
hard surface
● Falling into or jumping over a deep hole
● Landing hard or vehicle falling
●Collision from the side
● Collision from the rear
● Vehicle rollover

94 1-8. Safety information
PRIUS_U_(L/O_0802)
■Types of collisions that m ay not deploy the SRS airbag
(side and curtain shield airbags [if equipped])
The SRS side airbag and curtain shield airbag system may not activate if the
vehicle is subjected to a collision from the side at certain angles, or a colli-
sion to the side of the vehicle body other than the passenger compartment.
The SRS side airbags and curtain shield airbags are generally not designed
to inflate if the vehicle is involved in a frontal or rear collision, if it rolls over,
or if it is involved in a low-speed side collision.
● 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

When to contact your Toyota dealer
In the following cases, contact your Toyota dealer as soon as possible. Do
not disconnect the 12 volt battery cables before contacting your Toyota
dealer.
● 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 airbags to inflate.
● A portion of the doors is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain shield airbags to inflate.
● The pad section of the steering wheel,
front passenger airbag cover is
scratched, cracked, or otherwise dam-
aged.
● 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 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 driver 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 measured from the cen-
ter 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 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 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.
