SRS airbags
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.

Curtain shield airbags
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This information includes crash severity and
occupant information. 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 occupants.

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.
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 measured 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 ped-
als comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) 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 by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.

WARNING
■ SRS airbag precautions
● If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also been
fastened to the latch plate of the seat
1
belt, the SRS front airbags will judge
that the driver and front passenger are
wearing the seat belt even though the
seat belt has not been connected. In
this case, the SRS front airbags may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.
● 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 properly restrained. The rear seats are
safer for infants and children than the front passenger seat.

WARNING
■ SRS airbag precautions
●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.
●Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
1-1. For safe use
47
WARNING
■ SRS airbag precautions
●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.
1
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
●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.
● Do not hang coat hangers or hard objects on the coat hooks. All of these
items could become projectiles and may cause death or serious injury,
should the SRS curtain shield airbags deploy.
● If a 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.
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.
48
1-1. For safe use
WARNING
■ SRS airbag precautions
●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.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. 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 and CD
players
●Modifications to your vehicle for a person with a physical disability
1-1. For safe use
49
■ 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.
● 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.
1
●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 12 -
18 mph [20 - 30 km/h] 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.
●The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied. (P. 53)
■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 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS side and curtain shield airbags may also deploy in the event of a
severe frontal collision.
50
1-1. For safe use
■Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags and 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
■ Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally inflate 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.
●Collision from the side
●Collision from the rear
● Vehicle rollover
1-1. For safe use
51
■ Types of collisions that may not deploy the SRS airbags
(SRS side and curtain shield airbags)
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.
●Collision from the side to the vehicle
body other than the passenger compart-
ment
1
●Collision from the side at an angle
The SRS side and 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 rear
● Vehicle rollover
52
1-1. For safe use
■ When to contact your Toyota dealer
In the following cases, the vehicle will require inspection and/or repair. Con-
tact your Toyota dealer as soon as possible.
●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 front airbags to inflate.
● 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 or lower portion of the driver’s side
instrument panel is scratched, cracked,
or otherwise damaged.
●The surface of the seats with the side
airbag is scratched, cracked, or other-
wise damaged.
●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
■ Front passenger occupant classification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “OFF” of the “PASSENGER AIR BAG” indicator is not illu-
minated when using the seat belt extender for the front passenger seat. If
the “OFF” of the “PASSENGER AIR BAG” indicator is illuminated, discon-
nect the extender tongue from the seat belt buckle, and reconnect the seat
belt. Reconnect the seat belt extender after making sure the “ON” of the
“PASSENGER AIR BAG” indicator is illuminated. If you use the seat belt
extender while the “OFF” of the “PASSENGER AIR BAG” indicator is illu-
minated, the SRS airbags for the front passenger will not activate, which
could cause death or serious injury in the event of a collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.
1-1. For safe use
57
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
1
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 remains 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 forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. (P. 63)
● 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 your
Toyota dealer 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.
