front passenger occupant classification in-

dicator light will indicate “OFF” if there is

a malfunction in the front passenger occu-

pant classification system.

In the following cases, contact your Toyota

dealer as soon as possible:

The SRS (Supplemental Restraint Sys-

tem) front airbags are designed to pro-

vide further protection for the driver

and front passenger in addition to the

primary safety protection provided by

the seat belts.

D The front of the vehicle (shaded in the

illustration) was involved in an accident

that was not severe enough to cause

the seat belt pretensioners to operate.

Your vehicle is equipped with “ADVANCED

AIRBAGS” designed based on US motor

vehicle safety standards (FMVSS208). The

airbag system controls airbag deployment

power for the driver and front passenger.

The driver airbag system consists of the

driver seat’s position sensor etc. The front

passenger’s airbag system consists of the

front passenger occupant classification

sensor etc.

D Either seat belt pretensioner assembly

or surrounding area is scratched,

cracked, or otherwise damaged.

In response to a severe frontal impact,

the SRS front airbags work with the seat

belts to help reduce injury by inflating.

The SRS front airbags help reduce injuries

mainly to the driver’s or front passenger’s

head or chest caused by hitting the ve-

hicle interior.

infants and children can be killed

or seriously injured by the deploy-

ing airbags. An infant or child who

CAUTION

D The SRS front airbag system is de-

signed only as a supplement to the

primary protection of the driver and

front passenger seat belt systems.

The driver and front passenger can

be killed or seriously injured by the

inflating airbags if they do not wear

the available seat belts properly.

During sudden braking just before

a collision, an unrestrained driver

or front passenger can move for-

ward into direct contact with or

close proximity to the airbag which

may then deploy during the colli-

sion. To ensure maximum protection

in an accident, the driver and all

passengers in the vehicle must

wear their seat belts properly. Wear-

ing a seat belt properly during an

accident reduces the chances of

death or serious injury or being

thrown out of the vehicle. For in-

structions and precautions concern-

ing the seat belt system, see “Seat

belts” on page 64 in this Section.

The SRS front passenger airbag will not

activate if there is no passenger sitting in

the front passenger seat. However, the

front passenger airbag may deploy if lug-

gage is put in the seat, or the seat belt

is buckled up, regardless of the presence

of an occupant in the seat. (As for the

front passenger occupant classification

system, see “—Front passenger occupant

classification system” on page 91 in this

strongly recommends that all in-

fants and children be placed in the

rear seat of the vehicle and proper-

ly restrained. The rear seat is the

safest for infants and children. For

instructions concerning the installa-

tion of a child restraint system, see

“Child restraint” on page 96 in this

Section.

Always wear your seat belt properly.

The SRS front airbags are designed to

deploy in severe (usually frontal) colli-

sions where the magnitude and duration

of the forward deceleration of the ve-

hicle exceeds the designed threshold

level.

Collision from the rear

The SRS front airbags will deploy if the

severity of the impact is above the de-

signed threshold level, comparable to an

approximate 25 km/h (15 mph) collision

when the vehicle has the impact straight

into a fixed barrier that does not move or

deform.

The SRS front airbags are not generally

designed to inflate if the vehicle is in-

volved 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, de-

ployment of the SRS front airbags may

occur.

The SRS front airbags may also deploy

if a serious impact occurs to the under-

side of your vehicle. Some examples

are shown in the illustration.

underride collision (e.g.

a

collision in

which the front of the vehicle “underrides”,

or goes under, the bed of a truck, etc.).

It is possible that in some collisions

where the forward deceleration of the ve-

hicle is very close to the designed thresh-

old level, the SRS front airbags and the

seat belt pretensioners may not activate

together.

Always wear your seat belts properly.

8. Driver’s seat position sensor

9. Airbag sensor assembly

Deployment of the airbags happens in a

fraction of a second, so the airbags must

inflate with considerable force. While the

system is designed to reduce serious inju-

ries, primarily to the head and chest, it

may also cause other, less severe injuries

to the face, chest, arms and hands. These

are usually in the nature of minor burns

or abrasions and swelling, but the force of

a deploying airbag can cause more seri-

ous injuries, especially if an occupant’s

hands, arms, chest or head is in close

proximity to the airbag module at the time

of deployment. This is why it is important

for the occupant to: avoid placing any

object or part of the body between the

occupant and the airbag module; sit

straight and well back into the seat; wear

the available seat belt properly; and sit as

far as possible from the airbag module,

while still maintaining control of the ve-

hicle.

10. Airbag module for driver

(airbag and inflator)

The airbag sensor assembly consists of a

safing sensor and airbag sensor.

CY13280

The front airbag sensors constantly moni-

tor the forward deceleration of the vehicle.

If an impact results in a forward decelera-

tion beyond the designed threshold level,

the system triggers the airbag inflators. At

this time a chemical reaction in the infla-

tors very quickly fills the airbags with

non−toxic gas to help restrain the forward

motion of the occupants. The front airbags

then quickly deflate, so that there is no

obstruction of the driver’s vision should it

be necessary to continue driving.

The SRS front airbag system consists

mainly of the following components, and

their locations are shown in the illustra-

tion.

1. Front airbag sensors

2. SRS warning light

When the airbags inflate, they produce a

loud noise and release some smoke and

residue along with non−toxic gas. This

does not indicate a fire. This smoke may

remain inside the vehicle for some time,

and may cause some minor irritation to

the eyes, skin or breathing. Be sure to

wash off any residue as soon as possible

to prevent any potential skin irritation with

soap and water. If you can safely exit

from the vehicle, you should do so imme-

diately.

3. Front passenger occupant classification

Parts of the airbag module (steering wheel

hub, airbag cover and inflator) may be hot

for several minutes after deployment, so

do not touch! The airbags inflate only

once. The windshield may be damaged by

absorbing some of the force of the inflat-

ing airbag.

D The driver sit as far back as pos-

sible from the steering wheel while

still maintaining control of the ve-

hicle.

D The front passenger sit as far back

as possible from the dashboard.

D All vehicle occupants be properly

restrained using the available seat

belts.

D Do not sit on the edge of the seat

or lean against the dashboard when

the vehicle is in use, since the

front passenger airbag could inflate

with considerable speed and force.

Anyone who is up against, or very

close to, an airbag when it inflates,

can be killed or seriously injured.

Sit up straight and well back in the

seat, and always use your seat belt

properly.

D Toyota strongly recommends that all

infants and children be placed in

the rear seat of the vehicle and be

properly restrained.

For instructions and precautions con-

cerning the seating position, see

“—Front seat precautions” on page

42 in this Section.

D Do not hold a child on your lap or

in your arms. Use a child restraint

system in the rear seat. For instruc-

tions concerning the installation of

—SRS side airbags and

curtain shield airbags

In response to a severe side impact, the

SRS side airbag and curtain shield airbag

in the impacted side work with the seat

belts to help reduce injury by inflating.

The SRS side airbags help reduce injuries

mainly to the driver’s or front passenger’s

chest. The SRS curtain shield airbags

help reduce injuries mainly to the driver’s,

front passenger’s or rear/second passen-

ger’s head and help prevent them from

being thrown out of the vehicle.

NOTICE

Do not disconnect the battery cables

before contacting your Toyota dealer.

CY13073

The SRS side airbag on the passenger

seat will not activate if there is no pas-

senger sitting in the front passenger seat.

However, the side airbag on the passen-

ger seat may deploy if luggage is put in

the seat, or the seat belt is buckled up

regardless of the presence of the occu-

pant in the seat. (As for the front passen-

ger occupant classification system, see

ries, it may also cause minor burns or

abrasions and swelling.

Improper sitting and wearing of the

seat belts may not retain you inside

the vehicle.

D Do not allow anyone to lean against

the door when the vehicle is in use,

since the side airbag and curtain

shield airbag could inflate with con-

siderable speed and force. Other-

wise, he/she may be killed or seri-

ously injured. Special care should

be taken especially when you have

a small child in the vehicle.

Front seats as well as parts of the front

and rear pillars, front, center and rear

garnish and roof interior may be hot for

several minutes, but the airbags them-

selves will not be hot. The airbags are

designed to inflate only once.

D Sit up straight and well back in the

seat, distributing your weight evenly

If the front passenger occupant classifica-

tion system determines that a person of

adult size sits in the front passenger seat

but the “OFF” indicator is illuminated, one

of the following is likely to have occurred:

The front passenger occupant classifi-

cation indicator light will indicate “ON”

and “OFF” when the engine switch is

turned to the “ON” position. After

about four seconds, it will go off. After

that, the front passenger occupant clas-

sification system operates and judges

whether to indicate “ON” or “OFF”.

D A rear passenger lifts the front passen-

ger seat cushion with their legs.

CY13299a

D Objects are placed under the front pas-

senger seat.

D The front passenger seatback is in

contact with the rear/second seat.

To ensure the system correctly detects an

adult sitting in the front passenger seat,

make sure the above do not occur.

The SRS warning light will come on

and front passenger occupant classifi-

cation indicator light will indicate

“OFF” if there is a malfunction in the

front passenger occupant classification

system.

Make sure that the “ON” indicator is illu-

minated when an adult is seated in the

front passenger seat. If the “OFF” indica-

tor is illuminated, ask the passenger to sit

up straight, well back in the seat, and

with the seat belt worn correctly. If the

“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.

: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may

recognize him/her as a child depending on his/her physique and posture.

: 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.

: Never install a rear−facing child restraint system on the front passenger seat. A forward−facing child restraint system should only be

installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 96 in this Section as for installing the

child restraint system.)

D Do not recline the front passenger

seatback so far that it touches a

second seat. This may cause the

“OFF” indicator to be illuminated,

which indicates that the passen-

ger’s airbags will not deploy in the

event of a severe accident. If the

seatback touches the rear/second

seat, return the seatback to a posi-

tion where it does not touches the

rear/second seat.

D Wear the seat belt properly.

CAUTION

D Make sure the front passenger’s

seat belt tab has not been left in-

serted into the buckle before some-

one sits in the front passenger

seat.

To avoid potential death or serious

injury when the front passenger occu-

pant classification system does not

detect the conditions correctly, ob-

serve the following.

D Do not apply a heavy load to the

front passenger seat.

D Make sure the front passenger oc-

cupant classification indicator light

indicates “ON” when using the seat

belt extender for the front passen-

ger seat. If the indicator light indi-

cates “OFF”, disconnect the extend-

er tongue from the seat belt buckle,

then reconnect the seat belt. Recon-

nect the seat belt extender after

making sure the indicator light indi-

cates “ON”. If you use the seat belt

extender while the indicator light

indicates “OFF”, the front passen-

ger airbag and side airbag on the

front passenger side may not acti-

vate correctly, which could cause

death or serious injury in the event

of collision.

D Do not put weight on the front pas-

senger seat by putting your hands

or feet on the front passenger seat

seatback from the rear/second pas-

senger seat.

Keep the front passenger seatback

as upright as possible when the ve-

hicle is moving. Reclining the seat-

back excessively may lessen the ef-

fectiveness of the seat belt system.

D Do not let a rear/second passenger

lift the front passenger seat with

their feet or press on the seatback

with their legs.

D If an adult sits in the front passen-

ger seat, the occupant classification

indicator light should indicate “ON”.

If the “OFF” indicator is illumina-

ted, 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 “OFF” indica-

tor still remains illuminated, either

ask the passenger to move to the

rear/second seat, or if that is not

possible, move the front passenger

seat fully rearward.

D Do not put objects under the front

passenger seat.

D Child restraint systems installed on

the rear/second seat should not

contact the front seatbacks.
