SRS airbags
◆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 driver’s knee airbag
Can help provide driver protection
◆SRS side and curtain shield airbags
SRS side airbags (if equipped)
Can help protect the torso of the front seat occupants
SRS curtain shield airbags (if equipped)
Can help protect primarily the head of occupants in the outer
seats
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.

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.
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 devic es 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 sev-
eral 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 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 maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.

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 (if equipped) of the vehi cle and properly restrained. The rear
seats (if equipped) are safer for infants and children than the front passen-
ger seat. ( P. 65)
●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.

WARNING
■SRS airbag precautions
●Vehicles with SRS side and curtain
shield airbags: Do not lean against the
door, the roof side rail or the front, side
and rear pillars.
● Vehicles with SRS side and curtain
shield airbags: Do not allow anyone to
kneel on the passenger seat toward the
door or put their head or hands outside
the vehicle.
● 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.
● Vehicles with SRS side and curtain
shield airbags: Do not attach anything
to areas such as a door, windshield,
side door glass, front or rear pillar, roof
side rail and assist grip.

WARNING
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows or
winches
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios (RF-trans-
mitter) and CD players

■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 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 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 will activate.
● Vehicles with front passenger occupant classification system: The SRS front
airbags for the front passenger will not activate if there is no passenger sit-
ting in the front passenger seat. However, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoc-
cupied.
■ 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 1500 kg [3300 lb.] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
● All SRS side and curtain shield airbags will 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, SRS side and curtain shield airbags may also deploy
if a serious impact occurs to the underside of your vehicle. 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

For safety and security
●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.
● Vehicles with SRS side and curtain
shield airbags: A portion of a door or its
surrounding area is damaged or
deformed, 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 cover or lower portion of the instru-
ment panel is scratched, cracked, or
otherwise damaged.
● Vehicles with SRS side airbags: The sur-
face of the seats with the SRS side air-
bag is scratched, cracked, or otherwise
damaged.
● Vehicles with SRS curtain shield air-
bags: The portion of the front pillars, rear
pillars or roof side rail garnishes (pad-
ding) containing the SRS curtain shield
airbags inside is scratched, cracked, or
otherwise damaged.
