SRS airbags
The SRS airbags inflate when the vehicle is subjected to cer-
tain 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.

Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity 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.
■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 (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. T he airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. ( P.89)
●All of the doors will be unlocked.
( P.223)
●The brakes and st op lights will be
controlled automatically.
(  P.408)
●The interior lights will turn on auto-
matically. ( P.436)
●The emergency flashers will turn
on automatically. ( P.534)
●For Safety Connect subscribers, if
any of the following situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. ( P.65)
• An SRS airbag is deployed.
• A seat belt pretensioner is acti-
vated.
• The vehicle is involved in a severe
rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e 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

●Collision from the side
●Collision from the rear
●Vehicle rollover
■Types of collisions that may not
deploy the SRS airbags (SRS
side and curtain shield airbags)
The SRS side and curtain shield air-
bags may not activate if the vehicle
is subjected to a c ollision from the
side at certain angl es, or a collision
to the side of the vehicle body other
than the passenger compartment.
●Collision from the s ide to the vehi-
cle body other than the passenger
compartment
●Collision from the s ide at an angle
The SRS side airbags do not gener-
ally inflate if the vehicle is involved
in a frontal or rear c ollision, if it rolls
over, or if it is involved in a low-
speed side collision.
●Collision from the front
●Collision from the rear
●Vehicle rollover The SRS curtain sh
ield airbags do
not generally inflate if the vehicle is
involved in a rear collision, if it
pitches end over en d, or if it is
involved in a low- speed side or low-
speed frontal collision.
●Collision from the rear
●Pitching end over end
■When to contact your Toyota
dealer
In the following ca ses, the vehicle
will require inspectio n and/or repair.
Contact your Toyota dealer as soon
as possible.
●Any of the SRS airbags have
been inflated.
●The front of the vehicle is dam-
aged or deformed, or was
involved in an accident that was
not severe enough to cause the
SRS front airbags to inflate.
●A portion of a door or its surround-
ing area is damaged, deformed or
has had a hole made in it, or the

WARNING
●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
system. Toyota strongly recom-
mends that all infants and chil-
dren be placed in the rear seats
of the vehicle and properly
restrained. The rear seats are
safer for infants and children
than the front pa ssenger seat.
(  P.50)
●Do not sit on the edge of the
seat or lean against the dash-
board.
●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 occu-
pants to hold items on their
knees.
●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.
●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 pro-
jectiles when the SRS driver,
front passenger and knee air-
bags deploy.

WARNING
●Do not attach anything to areas
such as a door, windshield, side
window, front or rear pillar, roof
side rail and assist grip.
●Do not hang coat hangers or
other 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 and SRS seat
cushion airbag inflate as they
may interfere with inflation of
the SRS airbags. Such acces-
sories may prevent the SRS
side airbags and SRS seat
cushion airbag from activating
correctly, disable the system or
cause the SRS side airbags and
SRS seat cushion airbag to
inflate accidentally, resulting in
death or serious injury.
●Do not strike or apply significant
levels of force to the area of the
SRS airbag components or the
front doors.
Doing so can cause the SRS
airbags to malfunction.
●Do not touch any of the compo-
nent 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 win-
dow 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 air-
bags 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 passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
●Installation, re moval, disassem-
bly and repair of the SRS air-
bags
●Repairs, modific ations, removal
or replacement of the steering
wheel, instrument panel, dash-
board, seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,
front door trims or front door

■Front passenger occupant
classification system precau-
tions
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 pas-
senger seat.

WARNING
●Child restraint systems installed
on the rear seat should not con-
tact the front seatbacks.
●Do not use a seat accessory,
such as a cushion and seat
cover, that covers the seat
cushion surface.
●Do not modify or replace the
upholstery of the front seat.
●Adjust the front passenger seat
so that the head restraint does
not touch the ceiling. If the head
restraint is left in contact with
the ceiling, the system may not
detect the front passenger prop-
erly, leading to improper opera-
tion of the airbags.
