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 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.
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 of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 55)
●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 without SRS curtain shield
airbags: Do not lean against the front
door.
● Vehicles with SRS curtain shield
airbags: Do not lean against the door,
the roof side rail or the front, side and
rear pillars.
● Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
● Vehicles without an SRS driver knee
airbag: Do not attach anything to or lean
anything against areas such as the
dashboard or steering wheel pad.
These items can become projectiles
when the SRS driver and front passen-
ger airbags deploy.
● Vehicles with an SRS driver knee air-
bag: Do not attach anything to or lean
anything against areas such as the
dashboard, steering wheel pad and
lower portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and driver knee airbags deploy.

WARNING
■SRS airbag precautions
● Vehicles with SRS curtain shield airbags: Do not hang coat hangers or
other hard objects on the coat hooks. All of these items could become pro-
jectiles and may cause death or serious injury, should the SRS curtain
shield airbags deploy.
● Vehicles with an SRS driver knee airbag: If a vinyl cover is put on the area
where the SRS driver 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 SRS airbags.
Such accessories may prevent the si de airbags from activating correctly,
disable the system or cause the side ai rbags to inflate accidentally, result-
ing in death or serious injury.
● Vehicles without SRS curtain shield
airbags: Do not attach anything to areas
such as a door, windshield glass and
side door glass.
● Vehicles with SRS curtain shield
airbags: Do not attach anything to areas
such as a door, windshield glass, side
door glass, front or rear pillar, roof side
rail and assist grip. (Except for the
speed limit label P. 475)
● Vehicles with an SRS driver knee air-
bag, but do not use a smart entry & start
system: Do not attach any heavy, sharp
or hard objects such as keys and
accessories to the key. The objects may
restrict the SRS driver 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.

WARNING
■SRS airbag precautions
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS
airbags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have 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.
● Vehicles without SRS curtain shield airbags: If the areas where the SRS
airbags are stored, such as the steering wheel pad, are damaged or
cracked, have them replaced by any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional.
● Vehicles with SRS curtain shield airbags: If the areas where the SRS
airbags are stored, such as the steer ing wheel pad and front and rear pillar
garnishes, are damaged or cracked, have them replaced by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
■ 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 dealer or repairer, or another duly
qualified and equipped professional. 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,
winches
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios (RF-trans-
mitter) and CD players

■If the SRS airbags deploy (inflate)
● Slight abrasions, burns, bruising, etc., may be sustained from SRS airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● A loud noise and white powder will be emitted.
● Vehicles without SRS curtain shield airbags: Parts of the airbag module
(steering wheel hub, airbag cover and inflator) as well as the front seats may
be hot for several minutes. The airbag itself may also be hot.
● Vehicles with SRS curtain shield airbags: Parts of the airbag module (steer-
ing 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.
■ 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.
■ SRS airbag deployment conditions (SRS side airbags and SRS curtain
shield airbags [if equipped])
● 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 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 curtain shield airbags may also deploy if a seri-
ous 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
airbags)
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

YARIS_F_OM_Europe_OM52J20E
■ Types of collisions that may not deploy the SRS airbags
(SRS side airbags and SRS curtain shield airbags [if equipped])
The SRS side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
The SRS side airbags do not generally 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.
The SRS curtain shield airbags do not generally inflate if the vehicle is
involved in a rear collision, if it rolls over, or if it is involved in a low-speed side
or low-speed frontal collision.
● Collision from the side to the vehicle
body other than the passenger compart-
ment
● Collision from the side at an angle
●Collision from the front
● Collision from the rear
● Vehicle rollover
●Collision from the rear
● Vehicle rollover
