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.
The SRS curtain shield airbags may also deploy under the situations shown
in the illustration.
■ Types of collisions that may not de ploy 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. ● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or 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

The SRS side 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.
The SRS curtain shield airbags do not generally 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 or low-speed frontal collision. ● Collision from the side to the vehicle

There is a malfunction in the system
*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 not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt
*4: For some children, child in seat, child in booster seat or child in convert-ible seat, the system may not recognize him/her as a child. Factors
which may affect this can be the physique or posture.
*5: Never install a rear-facing child restraint system on the front passengerseat. A forward-facing child restraint system should only be installed on
the front passenger seat when it is unavoidable. ( →P. 52)
*6: In case the indicator light is not illuminated, consult this manual on how
to install the child restraint system properly. ( →P. 56)

WARNING
■Front passenger occupant classi fication system precautions
Observe the following precautions regarding the front passenger occupant
classification 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 “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “A IR BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front passenger may 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 fee\
t or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.

WARNING
■Front passenger occupant classi fication system precautions
● Do not recline the front passenger seatback so far that it touches the rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the SRS airbags for the front passenger will not
deploy in the event of a severe accident. If the seatback 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 possible 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, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator 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 the “AIR BAG OFF” 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. 56)
● 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.
