SRS front airbag
The driver’s SRS front ai
rbag is stowed in the cent er portion of the steering
wheel. The driver’s knee airbag is stowed under the steering column. The
passenger’s SRS front airbag is stowed near the top of the dashboard under
an “SRS AIRBAG” mark.
In a moderate to severe front collision, the following components deploy.
● SRS front airbag for driver
● SRS front airbag for front passenger
● Knee airbag for driver
These components supplement the seat belts by reducing the impact to the
occupant’s head, chest and knees.
■ If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS air-
bags, 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.
■ Front-seat passenger airbag manual cut off switch
The passenger-side front airbag can be deactivated by the cut off switch
located in the instrumental panel side. When the cut off switch is turned to
the deactivation mode the passenger-s ide front airbag becomes deacti-
vated. When the cutoff switch is turned to the activation mode the passen-
ger-side front airbag becomes active to deploy. While the passenger-side
front airbag is active the A/B ON indicator is illuminated.

The SRS front airbag (and also the knee airbag) is designed to deploy in the
event of an accident involving a moderate to severe front collision. It is not
designed to deploy in most lesser front impacts because the necessary pro-
tection can be achieved by the seat belt alone. Also, it is not designed to
deploy in most side or rear impacts or in most roll-over accidents because
deployment of the SRS front airbag would not help the occupant in those sit-
uations.
The SRS airbag is designed to f
unction on a one-time-only basis.
SRS airbag deployment depends on the level of force experienced in the
passenger compartment during a collision. That level differs from one type of
collision to another, and it may have no bearing on the visible damage done
to the vehicle itself.
■ When will the SRS front airbag most likely deploy?
■ At what other times might the SRS front airbag deploy? A head-on collision against a thick con-
crete wall at a vehicle speeds of 20 to 30
km/h (12 to 19 mph) or higher activates
the SRS front airbag. The SRS front air-
bag will also be activated when the vehi-
cle is exposed to a front impact similar in
fashion and magnitude to the collision
described above.
The SRS front airbag may be activated
when the vehicle sustains a hard impact
in the undercarriage area from the road
surface (such as when the vehicle
plunges into a deep ditch, is severely
impacted or knocked hard against an
obstacle on the road such as a curb).

SRS side airbag and SRS curtain shield airbag
The SRS side airbag is stored in the
door side of each front seat seatback,
which bears an “SRS AIRBAG” label.
In a moderate to severe side impact collision, the SRS side airbag on the
impacted side of the vehicle deploys between the occupant and the door
panel and supplements the seat belt by reducing the impact on the occupant’s
chest.
The curtain shield airbag on each side of the cabin is stored in the roof side
(between the front pillar and a point over the rear seat). An “SRS AIRBAG”
mark is located at the top of each front and rear pillar.
In a moderate to severe side impact collision, the SRS curtain shield airbag on
the impacted side of the vehicle deploys between the occupant and the side
window and supplements the seat belt by reducing the impact on the occu-
pant’s head.
■ Operation
The SRS side airbag and SRS curtain shield airbag can function only when
the engine switch is in the “ON” position (vehicles without a smart entry &
start system) or when the “ENGINE START STOP” switch is in IGNITION
ON mode (vehicles with a smart entry & start system).

WARNING
■
If the SRS airbags deploy
Do not touch the SRS side airbag system components around the front seat
seatback with bare hands right after deployment. Doing so can cause burns
because the components can be very hot as a result of deployment.
After deployment, do not touch any part of the SRS curtain shield airbag sys-
tem (from the front pillar to the part of the roof side over the rear seat). Doing
so can cause burns because the components can be very hot as a result of
deployment.
■ 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 v ehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● 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.

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 of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( →P. 136)
●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
●If the 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 inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags 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 ( →P. 111 ) .
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.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or 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 ar e stored, such as the steering wheel
pad and front and rear pillar garni shes, are damaged or cracked, have
them replaced by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
● The SRS side airbag and SRS curtain shield airbag are designed only to
be a supplement to the primary protection provided by the seat belt. They
do not do away with the need to fasten seat belts. It is also important to
wear your seat belt to help avoid injuries that can result when an occupant
is not seated in a proper upright position.
●Vehicles without a smart entry & start
system only: Do not attach any heavy,
sharp or hard objects such as keys and
accessories to the key. The objects
may restrict the SRS knee airbag infla-
tion or be thrust into the driver's seat
area by the force of the deploying air-
bag, thus causing a danger.

SRS airbag system monitor
■ SRS warning light
A diagnostic system continually
monitors the readiness of the
SRS airbag system (including
front seat belt pretensioners)
while the vehicle is being driven.
The SRS warning light will show
normal system operation by illu-
minating for approximately 6
seconds when the engine switch
is turned to the “ON” position
(vehicles without a smart entry &
start system), or the “ENGINE
START STOP” switch is turned
to IGNITION ON mode (vehicles
with a smart entry & start sys-
tem).
The following components are monitored by the indicator.
● Front sub sensor
• Right-hand side
• Left-hand side
● Airbag control module (including impact sensor)
● Front airbag module
• Driver’s side
• Front passenger’s side
● Knee airbag module (driver’s side)
