114 1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls ai rbag 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 airb ags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
■ SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensor assemblies, curtain shield
airbag sensor assemblies, driver’s seat position sensor, driver’s seat belt
buckle switch, front passenger occupant classification system (ECU and
sensors), AIR BAG ON and AIR BAG OFF indicator lights, front passenger’s
seat belt buckle switch, front seat belt pretensioner assemblies, airbags,
interconnecting wiring and power sources. ( →P. 470)
■ 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, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The front windshield may crack.

Operating conditions (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 approxi-
mately 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 if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision (e.g.
a collision in which the front of the vehicle “underrides”, or goes under the
bed of a truck, etc.).
● Depending on the type of collision, it is possible that only the seat belt
pretensioners 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
airbags for the front passenger may deploy if luggage is put in the seat,
even if the seat is unoccupied. (→P. 124)
■ Operating conditions (side airb ags & curtain shield airbags)
The SRS side airbags & SRS curtain shield airbags will deploy in the event
of an impact that exceeds the set threshold level (the level of force c\
orre-
sponding 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]).
■ Operating conditions (c urtain shield airbags)
The SRS curtain shield airbags are designed to inflate when the passenger
compartment is subjected to a severe impact from the side or vehicle roll-
over. Depending on the conditions and type of accident, there are times
when the curtain shield airbags may deploy (inflate) in a front impact.

116 1-7. Safety information
■Conditions under which the SRS airbags may deploy (inflate), other
than a collision
The SRS front airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situation shown
in the illustration.
■ Types of collisions that may not depl oy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to 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.
● Hitting a curb, edge of pavement or
hard surface
● Falling into or jumping over a deep hole
● Landing hard or vehicle falling
●The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.
●Collision from the side
● Collision from the rear
● Vehicle rollover

Types of collisions that may not deploy the SRS airbag
(side airbags and curtain shield airbags)
The SRS side airbag and curtain shield airbag system may not activate if the
vehicle is subjected to a collision from the side at certain angles, or a colli-
sion to the side of the vehicle body other than the passenger compartmen\
t.
The SRS side airbags are not generally designed to 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 are not generally designed to inflate if the
vehicle is involved in a rear collision, if it pitches end over end, or if it is
involved in a low-speed side collision.
● Collision from the side to the vehicle
body other than the passenger com-
partment
● Collision from the side at an angle
●Collision from the front
● Collision from the rear
● Vehicle rollover
●Collision from the front*
●Collision from the rear
● Pitching end over end
*: Depending on the conditions and type
of accident, the curtain shield airbags
may deploy (inflate) upon frontal
impact.

118 1-7. Safety information
■When to contact your Toyota dealer
In the following cases, contact 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 airbags to inflate.
● A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain shield airbags to inflate.
● The pad section of the steering wheel,
dashboard near the front passenger
airbag or lower portion of the
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.

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 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 now sit less than 10
in. (250 mm) away, 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 designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, sim-
ply 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
airbag 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 and steering wheel, and your
view of the instrument panel controls.

120 1-7. Safety information
CAUTION
■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 v\
ery
close to the airbag. The front passenger seat should be as far from the
airbag 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 pr operly restrained. The rear seats are
the safest for infants and children. ( →P. 129)
●If the seat belt extender has been
connected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat 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.
