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

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.

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.

●

If the pretensioner has acti-

vated, the SRS warning light will

come on. In that case, the seat

belt cannot be used again and

must be replaced at your Toyota

dealer.

“AIRBAG ON” and “AIRBAG OFF” indicator lights

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.

●

The fuel cell system will be

stopped and hydrogen supply will

be stopped from the hydrogen

tank valves. (

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. (

■

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

37

1-1. For safe use

For
safety and secu

rity

• 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

●

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.

■

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.

■

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.

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.

40

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. (Except

for the speed limit label



P.458)

42

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.

Pop Up Hood

In the event of a frontal col-
lision with a body, such as a
pedestrian, the Pop Up
Hood system raises the
hood to reduce the possibil-
ity of a serious impact to the
pedestrian’s head area by
adding clearance to the fuel
cell unit compartment.

When the sensors located
at the back of the front
bumper detect a frontal
impact with a body, such as
a pedestrian, which meets
or exceeds the threshold
level while the vehicle is
being driven within the
operational speed range,
the system operates.

Pop Up Hood precautions

●

Before scrapping your vehicle,

make sure to contact your Toyota

dealer.

●

The Pop Up Hood system cannot

be reused once it has operated.

Have it replaced by your Toyota

dealer.

■

PCS-linked Pop Up Hood opera-

tion control

If the PCS (Pre-Collision System)

determines that the possibility of a

collision with a pedestrian or bicy-

clist is high, the Pop Up Hood will be

prepared to operate.

■

Pop Up Hood operational condi-

tions

The Pop Up Hood will operate when

the vehicle detects an impact such

as the following:

●

The front bumper detects a frontal

impact equivalent to or greater

than that of a pedestrian while the

vehicle being driven within the

operational speed range of

approximately 16 to 34 mph (25 to

55 km/h). (The system is operated

by an impact of threshold level or

greater, even in the case of a

minor collision that may not leave

a trace on the front bumper. Also,

depending on the impact condi-

tions or vehicle speed, the system

may operate by a collision with a

light or small object or a small ani-

mal.)

●

In other situations, such as the fol-

lowing the system may operate

when an impact is applied to the

lower part of the vehicle or front

bumper:

• Colliding with a curb

• Falling into a deep hole

• Landing hard

• Hitting the slope of a parking lot,

an undulating road, a protruding

object or falling object

■

Conditions under which the

Pop Up Hood may not operate

properly

●

If a pedestrian collides with the

right or left corner of the front

bumper or the side of the vehicle.

As such impacts may be difficult to

detect, the system may not oper-

ate.

●

If the vehicle speed is not

detected correctly, such as if the

vehicle is sliding sideways, the

system may not operate properly.

■

Conditions under which the

Pop Up Hood will not operate

The Pop Up Hood will not operate in

the following situations:

●

Colliding with a lying person

●

A frontal impact applied to the

front bumper while driving at

speeds outside of the operational

speed range

●

A side impact or rear impact

●

A vehicle rollover (In some acci-

dent situations, the Pop Up Hood

may operate.)

WARNING

■

When the Pop Up Hood is

operated

●

Do not pull the hood lock

release lever. Doing so after the

Pop Up Hood has operated will

further raise the hood and may

cause an injury. Do not drive

with the hood raised, as doing

so may block the driver’s vision,

possibly causing an accident.

●

Do not forcibly push down the

hood. As the popped up hood

cannot be lowered by hand,

doing so may deform the hood

or cause an injury.

ated, have it replaced by your

Toyota dealer. If the Pop Up

Hood has operated, stop the

vehicle in a safe place and con-

tact your Toyota dealer.

●

Do not touch the lifters immedi-

ately after the Pop Up Hood has

operated, as the lifters may be

hot and burn you.

NOTICE

■

Pop Up Hood precautions

●

Make sure to close the hood

before driving, as the system

may not operate properly if the

hood is not fully closed.

●

Make sure that all 4 tires are of

the specified size and inflated to

the specified tire pressure. If

tires of a different size are used,

the system may not operate

properly.

●

If something has hit the area

around the front bumper, the

sensors may be damaged even

if the Pop Up Hood has not

operated. Have the vehicle

inspected by your Toyota

dealer.

●

Do not remove or repair the

parts or wiring of the Pop Up

Hood, as doing so may cause

accidental operation or prevent

the system from operating prop-

erly. If repair or replacement is

necessary, contact your Toyota

dealer.

●

Do not remove such compo-

nents as the front bumper, hood

or suspension, or replace them

with non-genuine parts, as

doing so may prevent the sys-

tem from operating properly.

●

Do not install anything to the

front bumper or hood, as doing

so may prevent the sensors

from detecting an impact cor-

rectly and prevent the system

from operating properly.

●

Do not close the hood with force

or apply load to the lifters, as

doing so may damage the lifters

and prevent the system from

operating properly.

●

Do not modify the suspension,

as changes made to the vehicle

height may prevent the system

from operating properly.

when using the seat belt

extender for the front passenger

seat. If the “AIRBAG OFF” indi-

cator light is illuminated, discon-

nect the extender tongue from

the seat belt buckle, and recon-

nect the seat belt. Reconnect

the seat belt extender after

making sure the “AIRBAG ON”

indicator light is illuminated. If

you use the seat belt extender

while the “AIRBAG OFF” indica-

tor light is illuminated, the SRS

airbags for the front passenger

cause death or serious injury in

the event of a collision.

●

Do not apply a heavy load to the

front passenger seat or equip-

ment (e.g. seatback pocket).

●

Do not put weight on the front

passenger seat by putting your

hands or feet on the front pas-

senger seat seatback from the

rear passenger seat.

●

Do not let a rear passenger lift

the front passenger seat with

their feet or press on the seat-

back with their legs.

●

Do not put objects under the

front passenger seat.

●

Do not recline the front passen-

ger seatback so far that it

touches a rear seat. This may

cause the “AIRBAG OFF” indi-

cator light to be illuminated,

which indicates that the SRS

airbags for the front passenger

will not activate 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 seat-

back as upright as possible

when the vehicle is moving.

Reclining the seatback exces-

sively may lessen the effective-

ness of the seat belt system.

●

If an adult sits in the front pas-

senger seat, the “AIRBAG ON”

indicator light is illuminated. If

the “AIRBAG 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 “AIRBAG OFF” indicator

still remains illuminated, either

ask the passenger to move to

the rear seat, or if that is not

possible, move the front pas-

senger 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 passenger

seat in the proper order.
