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) controls airbag deployment based on

information obtained from the sensors etc. shown in the system

components diagram above. This information 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.

are unable to communicate, the

agent automatically treats the call

as an emergency and helps to dis-

patch the necessary emergency

services. (P.72)

●Slight abrasions, burns, bruising

etc., may be sustained from SRS

airbags, due to the extremely high

speed deployment (inflation) by

hot gases.

• An SRS airbag is deployed.

• A seat belt pretensioner is acti-

vated.

• The vehicle is involved in a severe

rear-end collision.

●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. The airbag itself

may also be hot.

■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 force corresponding

to an approximately 12 - 18 mph

[20 - 30 km/h] frontal collision with

a fixed wall that does not move or

deform).

●The windshield may crack.

●The brakes and stop lights will be

controlled automatically. (P.249)

●The interior lights will turn on auto-

matically. (P.272)

However, this threshold velocity will

be considerably higher in the follow-

ing 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 colli-

sion in which the front of the vehi-

cle “underrides”, or goes under,

the bed of a truck

●The emergency flashers will turn

on automatically. (P.348)

●Fuel supply to the engine will be

stopped. (P.355)

●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

●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.

●Landing hard or falling

●The SRS seat cushion airbag on

the front passenger seat will not

operate if the occupant is not

wearing a seat belt.

The SRS curtain shield airbags may

also deploy under the situations

shown in the illustration.

■SRS airbag deployment condi-

tions (SRS side and curtain

shield airbags)

●The angle of vehicle tip-up is mar-

ginal.

●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 approxi-

mate speed of 12 - 18 mph [20 -

30 km/h]).

●The vehicle skids and hits a curb

stone.

■Types of collisions that may not

deploy the SRS airbags (SRS

front airbags)

●Both SRS curtain shield airbags

will deploy in the event of a side

collision on either side.

The SRS front airbags do not gener-

ally 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 decelera-

tion of the vehicle, deployment of

the SRS front airbags may occur.

●Both SRS curtain shield airbags

may also deploy in the event of a

severe frontal collision.

■Conditions under which the

SRS airbags may deploy

(inflate), other than a collision

●Collision from the side

●Collision from the rear

●Vehicle rollover

The SRS front airbags and SRS

side and curtain shield airbags may

also deploy if a serious impact

occurs to the underside of your vehi-

cle. Some examples are shown in

the illustration.

●Hitting a curb, edge of pavement

or hard surface

●Falling into or jumping over a deep

hole

■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 collision from the

side at certain angles, or a collision

to the side of the vehicle body other

than the passenger compartment.

dealer

In the following cases, the vehicle

will require inspection and/or repair.

Contact your Toyota dealer as soon

as possible.

●Collision from the side at an angle

●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.

The SRS side airbags do not gener-

ally 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.

●Collision from the front

●Collision from the rear

●Vehicle rollover

●A portion of a door or its surround-

ing area is damaged, deformed or

has had a hole made in it, or the

vehicle was involved in an acci-

dent that was not severe enough

to cause the SRS side and curtain

shield airbags to inflate.

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 rear

●Pitching end over end

●The pad section of the steering

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 supple-

mental devices to be used with

the seat belts.

●The seat cushion surface is

scratched, cracked, or otherwise

damaged.

●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 provides you with a margin

of safety. This distance is mea-

sured from the center of the steer-

ing wheel to your breastbone. If

you sit less than 10 in. (250 mm)

away now, you can change your

driving position in several ways:

●The surface of the seats with the

SRS side airbag is scratched,

cracked, or otherwise damaged.

• Move your seat to the rear as

far as you can while still reach-

ing the pedals comfortably.

●The portion of the front pillars, rear

pillars or roof side rail garnishes

(padding) containing the SRS cur-

tain shield airbags inside is

scratched, cracked, or otherwise

damaged.

• 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.

●Improperly seated and/or

restrained infants and children

WARNING

• If your steering wheel is adjust-

able, tilt it downward. This

points the airbag toward your

chest instead of your head and

neck.

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 passenger seat.

(P.48)

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.

●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.

●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.

●The SRS front passenger air-

bag also deploys with consider-

able 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

airbag as possible with the seat-

back adjusted, so the front pas-

senger sits upright.

●Do not allow the front seat occu-

pants to hold items on their

knees.

WARNING

●Do not attach anything to areas

such as a door, windshield, side

windows, front or rear pillar, roof

side rail and assist grip.

●Do not lean against the door,

the roof side rail or the front,

side and rear pillars.

●Vehicles without a smart key

system: Do not attach any

heavy, sharp or hard objects

such as keys and accessories

to the key. The objects may

restrict the SRS knee airbag

inflation or be thrust into the

driver’s seat area by the force of

the deploying airbag, thus caus-

ing a danger.

●Do not allow anyone to kneel on

the passenger seats 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.

●Do not hang 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 driver’s knee

airbag will deploy, be sure to

remove it.

WARNING

●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 side air-

bags and seat cushion airbag

from activating correctly, disable

the system or cause the side

airbags and seat cushion airbag

to inflate accidentally, resulting

in death or serious injury.

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.

●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.

●Installation, removal, disassem-

bly and repair of the SRS air-

bags

●Repairs, modifications, 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

●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.

●Modifications to the front door

panel (such as making a hole in

it)

●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.
