104 1-7. Safety information
The SRS airbag can function only when the engine switch is in the “ON”
position (vehicles without a smart key system) or when the “ENGINE START
STOP” switch is in IGNITION ON mode (vehicles with a smart key system).
The Toyota advanced frontal airbag system is designed to determ ine the
activation or deactivation condition of the front passenger’s S RS frontal air-
bag depending on the characteristic of the item(s) or person on the front
passenger’s seat monitored by the front passenger’s occupant cl assification
system sensor. For this reason, only the driver’s SRS frontal a irbag may
deploy in the event of a collision, but this does not mean fail ure of the sys-
tem.
If the front sub sensors and the impact sensors in the airbag c ontrol module
detect a predetermined amount of force during a frontal collisi on, the control
module sends signals to the airbag module(s) (only driver’s mod ule or both
driver’s and front passenger’s modules) instructing the module( s) to inflate
the SRS frontal airbag(s).
The driver’s and front passenger’s SRS frontal airbags use dual stage infla-
tors. The two inflators of each airbag are triggered either seq uentially or
simultaneously, depending on the severity of impact, in the cas e of the
driver’s SRS frontal airbag and depending on the severity of im pact and the
characteristic of the item(s) or person on the seat in the case of the front
passenger’s SRS frontal airbag.
After deployment, the SRS airbag immediately starts to deflate so that the
driver’s vision is not obstructed. The time required from detec ting impact to
the deflation of the SRS airbag after deployment is shorter tha n the blink of
an eye.
Both when only the driver’s SRS frontal airbag deploys and the driver’s and
front passenger’s SRS frontal airbags deploy, the driver’s and front passen-
ger’s seat belt pretensioners operate at the same time.
Although it is highly unlikely that the SRS airbag would activa te in a non-
accident situation, should it occur, the SRS airbag will deflat e quickly, not
obscuring vision and will not interfere with the driver's abili ty to maintain con-
trol of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud inflation no ise will be
heard and some smoke will be released. These occurrences are a normal
result of the deployment. This smoke does not indicate a fire i n the vehicle.

Before driving
The driver’s SRS frontal airbag and front passenger’s SRS frontal airbag are
designed to deploy in the event of an accident involving a mode rate to
severe frontal collision. They are not designed to deploy in most lesser fron-
tal impacts because the necessary protection can be achieved by the seat
belt alone. Also, they are not designed to deploy in most side or rear impacts
or in most roll-over accidents because deployment of only the d river’s SRS
frontal airbag or both driver’s and front passenger’s SRS frontal airbags
would not help the occupant in those situations. The driver’s and front pas-
senger’s SRS frontal airbags are designed to function 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 fr om one type of
collision to another, and it may have no bearing on the visible damage done
to the vehicle itself.
■ Example of accident in which the driver’s/driver’s and front passen-
ger’s SRS frontal airbag(s) will most likely deploy
A head-on collision against a thick concrete wall at a vehicle speeds of 12 to
19 mph (20 to 30 km/h) or higher activates only the driver’s SR S frontal air-
bag or both driver’s and front passenger’s SRS frontal airbags. The airbag(s)
will also be activated when the vehicle is exposed to a frontal impact similar
in fashion and magnitude to the collision described above.

SRS side airbag and SRS curtain shield airbag
The SRS side airbag is stored in the door side of each front se at
seatback, which bears an “SRS AIRBAG” label.
In a moderate to severe side im pact collision, the SRS side airbag on
the impacted side of the vehicle deploys between the occupant and
the door panel and supplements t he seat belt by reducing the impact
on the occupant’s chest and waist. The SRS side airbag operates
only for front seat occupants.
The SRS curtain shield airbag on each side of the cabin is stor ed 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 occu-
pant and the side window and supplements the seat belt by reduc ing
the impact on the occupant’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 s mart key sys-
tem) or when the “ENGINE START ST OP” switch is in IGNITION ON mode
(vehicles with a smart key system).
The driver’s and front passenger’s SRS side airbags and SRS cur tain shield
airbags deploy independently of each other since each has its o wn impact
sensor. Therefore, they may not both deploy in the same acciden t. Also, the
SRS side airbag and SRS curtain shield airbag deploys independe ntly of the
driver’s and front passenger’s SRS front airbags in the steerin g wheel and
instrument panel.
A rollover sensor is also located inside the airbag control mod ule.
An impact sensor, which senses impact force, is located in each of the left
and right center pillars, doors and rear wheel houses. Another impact sen-
sor, which also senses impact force, is located under the center of the rear
seats.
If the impact sensor that is located under the center of the re ar seats and
one of the center pillar impact sensors or door impact sensors together
sense an impact force above a predetermined level in a side col lision, the
control module causes both the SRS side airbag and curtain shield airbag on
the impacted side to inflate regardless of whether the rear whe el house
impact sensor on the same side senses an impact.
If the impact sensor that is located under the center of the re ar seats and
one of the rear wheel house impact sensors together sense an im pact force
above a predetermined level, the control module causes only the SRS cur-
tain shield airbag on the impacted side to inflate.
If the rollover sensor detects rollover of the vehicle, the control module
inflates the SRS curtain shield airbags. At this time, the driver's and front
passenger’s seat belt pretensioners also operate at the same ti me.
118 1-7. Safety information
WARNING
■If the SRS airbags deploy
Do not touch the SRS side airbag system components around the f ront seat
seatback with bare hands right after deployment. Doing so can c ause burns
because the components can be very hot as a result of deployment.
After deployment, do not touch any part of the SRS curtain shie ld airbag sys-
tem (from the front pillar to the part of the roof side over th e rear seat). Doing
so can cause burns because the components can be very hot as a result of
deployment.
■ SRS side airbag and SRS curtain shield airbag precautions
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 impo rtant to wear
your seat belt to help avoid injuries that can result when an occupant is not
seated in a proper upright position.

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 se at 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.

SRS airbag precautions
●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 the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measu red from the
center 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 design s vary,
many drivers can achieve the 10 in. (250 mm) distance, even wit h the
driver seat all the way forward, simply by reclining the back o f the seat
somewhat. If reclining the back of your seat makes it hard to s ee 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 p oints the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, whil e
still maintaining control of the foot pedals, steering wheel, a nd your view of
the instrument panel controls.
● The SRS front passenger airbag al so deploys with considerable force, and
can cause death or serious injury especially if the front passe nger 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 passen ger 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 res traint 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. 137)
