■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 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 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
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. 2 0 1 )
■SRS airbag deployment conditions (SRS side and curtain shield air-
bags)
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 collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orien-
tation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).

CAUTION
■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
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 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.

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 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. (→P. 2 0 7 )
●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 belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags 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.

*1:The system judges a person of adult size as an adult. When a
smaller adult sits in the front passenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2:In the event the front passenger does not wear a seat belt.
*3:When a larger child who has outgrown a child restraint system
sits in the front passenger seat, the system may recognize him/
her as an adult depending on his/her physique or posture.
*4:Never install a rear-facing child restraint system on the front pas-
senger seat. A forward-facing child restraint system should only
be installed on the front passenger seat when it is unavoidable.
(→P. 2 0 7 )
*5:In case the indicator light is not illuminated, consult this manual
on how to install the child restraint system properly. (→P. 2 1 2 )
