Child seat belt usage

The seat belts of your vehicle were

principally designed for persons of

adult size.

●

Use a child restraint system

appropriate for the child, until the

child becomes large enough to

properly wear the vehicle’s seat

belt. (



P.53)

●

When the child becomes large

enough to properly wear the vehi-

cle’s seat belt, follow the instruc-

tions regarding seat belt usage.

(

P.29)

■

Seat belt extender

If your seat belts cannot be fastened

securely because they are not long

enough, a personalized seat belt

extender is available from your Toy-

ota dealer free of charge.

WARNING

●

Inspect the seat belt system

periodically. Check for cuts,

fraying, and loose parts. Do not

use a damaged seat belt until it

is replaced. Damaged seat belts

cannot protect an occupant

from death or serious injury.

●

Ensure that the belt and plate

are locked and the belt is not

twisted.

If the seat belt does not function

correctly, immediately contact

your Toyota dealer.

●

Replace the seat assembly,

including the belts, if your vehi-

cle has been involved in a seri-

ous accident, even if there is no

obvious damage.

●

Do not attempt to install,

remove, modify, disassemble or

dispose of the seat belts. Have

any necessary repairs carried

out by your Toyota dealer. Inap-

propriate handling may lead to

incorrect operation.

extender if you can fasten the

seat belt without the extender.

●

Do not use the seat belt

extender when installing a child

restraint system because the

belt will not securely hold the

child restraint system, increas-

ing the risk of death or serious

injury in the event of an acci-

dent.

●

The personalized extender may

not be safe on another vehicle,

when used by another person,

or at a different seating position

other than the one originally

intended.

The pretensioners help the seat
belts to quickly restrain the
occupants by retracting the seat
belts when the vehicle is sub-
jected to certain types of severe

frontal or side collision or a vehi-
cle rollover.

The pretensioners do not activate
in the event of a minor frontal
impact, a minor side impact or a
rear impact.

■

Replacing the belt after the pre-

tensioner has been activated

If the vehicle is involved in multiple

collisions, the pretensioner will acti-

vate for the first collision, but will not

activate for the second or subse-

quent collisions.

■

PCS-linked seat belt preten-

sioner control (vehicles with

Toyota Safety Sense 2.5)

If the PCS (Pre-Collision System)

determines that the possibility of a

collision with a vehicle is high, the

seat belt pretensioners will be pre-

pared to operate.

WARNING

■

Adjustable shoulder anchor

Always make sure the shoulder

belt is positioned across the cen-

ter of your shoulder. The belt

should be kept away from your

neck, but not falling off your shoul-

der. Failure to do so could reduce

the amount of protection in an

accident and cause death or seri-

ous injuries in the event of a sud-

den stop, sudden swerve or

accident.

seats)

WARNING

■

Seat belt pretensioners

Observe the following precautions

to reduce the risk of injury in the

event of sudden braking, sudden

swerving or an accident.

Failure to do so may cause death

or serious injury.

●

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 seat belt pretensioner

for the front passenger’s seat

may not activate in the event of

a collision.

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.

■

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. The airbag itself

may also be hot.

●

The windshield may crack.

●

All of the doors will be unlocked.

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. (

• 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 force 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
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-

1-1. For safe use

safety and secu

rity

sion in which the front of the vehi-

cle underrides, or goes under, the

bed of a truck

●

Depending on the type of collision,

it is possible that only the seat belt

pretensioners and knee airbags

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.

■

SRS airbag deployment condi-

tions (SRS side and curtain

shield airbags)

●

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]).

●

Both SRS curtain shield airbags

may deploy in the event of a

severe side collision.

●

Both SRS curtain shield airbags

will deploy in the event of vehicle

rollover.

●

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

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

●

Landing hard or falling

The SRS curtain shield airbags may

also deploy under the situations

shown in the illustration.

●

The angle of vehicle tip-up is mar-

ginal.

●

The vehicle skids and hits a curb

stone.

■

Types of collisions that may not

deploy the SRS airbags (SRS

front airbags)

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, when-

ever a collision of any type causes

sufficient forward deceleration of the

vehicle, deployment of the SRS

front airbags may occur.

●

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 collision from the

side at certain angles, or a collision

to the side of the vehicle body other

than the passenger compartment.

●

Collision from the side to the vehi-

cle body other than the passenger

compartment

●

Collision from the side at an angle

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

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

When to contact your Toyota

dealer

In the following cases, the vehicle

will require inspection 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

vehicle was involved in an acci-

dent that was not severe enough

to cause the SRS side and curtain

shield airbags to inflate.

1-1. For safe use

For
safety and secu

rity

●

The pad section of the steering

wheel, dashboard near the front

passenger airbag or lower portion

of the instrument panel is

scratched, cracked, or otherwise

damaged.

●

The surface of the seats with the

side airbag is scratched, cracked,

or otherwise damaged.

●

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.

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 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, plac-
ing yourself 10 in. (250 mm) from
your driver airbag provides 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 posi-
tion in several ways:

• Move your seat to the rear as

far as you can while still reach-

ing the pedals comfortably.

1-1. For safe use

WARNING

• 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.

• If your steering wheel is adjust-

able, tilt it downward. This

points the airbag 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.

●

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.

●

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.

●

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 passenger seat.

WARNING

●

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 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 attach anything to areas

such as a door, windshield, side

windows, front or rear pillar, roof

side rail and assist grip.

1-1. For safe use

WARNING

●

Do not hang coat hangers or

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 inflate as they

may interfere with inflation of

the SRS airbags. Such acces-

sories may prevent the SRS

side airbags from activating cor-

rectly, disable the system or

cause the SRS side airbags 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.
