For safety and security
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 (if equipped) deploy.
● Vehicles with SRS side and curtain
shield airbags: Do not attach anything
to areas such as a door, windshield
glass, side door glass, front or rear pil-
lar, roof side rail and assist grip.

■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]).
● The SRS side and 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, 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.
■ Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally infl ate 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

●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.
● Vehicles without SRS driver’s knee air-
bag: The pad section of the steering
wheel or dashboard near the front pas-
senger airbag is scratched, cracked, or
otherwise damaged.
Vehicles with SRS driver’s knee airbag:
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 side airbag is
scratched, cracked, or otherwise dam-
aged.
● Vehicles with SRS curtain shield air-
bags: The portion of the front pillars, rear
pillars or roof side rail garnishes (pad-
ding) containing the curtain shield air-
bags inside is scratched, cracked, or
otherwise damaged.

WARNING
■Front passenger occupant classification system precautions
● Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause “OFF” of the “PASSENGER AIR BAG” indicator to
be illuminated, which indicates that the SRS airbags for the front passen-
ger will not activate in the event of a severe accident. If the seatback
touches the rear seat, return the seatback to a position where it does not
touch the rear seat. Keep the front passenger seatback as upright as pos-
sible when the vehicle is moving. Reclining the seatback excessively may
lessen the effectiveness of the seat belt system.
● If an adult sits in the front passenger seat, “ON” of the “PASSENGER AIR
BAG” indicator is illuminated. If “OFF ” of the “PASSENGER AIR BAG” indi-
cator is illuminated, ask the passenger to sit up straight, well back in the
seat, feet on the floor, and with the seat belt worn correctly. If “OFF” of the
“PASSENGER AIR BAG” indicator still re mains illuminated, either ask the
passenger to move to the rear seat, or if that is not possible, move the
front passenger seat fully rearward.
● When it is unavoidable to install a child restraint system on the front pas-
senger seat, install the child restraint system on the front passenger seat
in the proper order. ( P. 65)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
front passenger occupant classification system. In this case, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.
● When it is unavoidable to install a rear-facing child restraint system on the
front passenger seat, do not release the seat belt while the vehicle is mov-
ing. Doing so may cause the airbag system to be on.

Deactivating the front seat passenger airbag
WARNING
■ When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as
long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
■ When a child restraint system is not installed on the front passenger
seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left off, the airbag may not deploy in the event of an accident, which
may result in serious injury or even death.
