1-1. For safe use

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 driver’s

knee airbags 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

WARNING

●

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.

WARNING

■

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.

1-1. For safe use

WARNING

●

Make sure the “AIR BAG OFF”

indicator light is not illuminated

when using the seat belt

extender for the front passenger

seat. If the “AIR BAG 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 “AIR BAG ON”

indicator light is illuminated. If

you use the seat belt extender

while the “AIR BAG OFF” indi-

cator light is illuminated, the

SRS airbags for the front pas-

senger will not activate, which

could 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 “AIR BAG 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 “AIR BAG ON”

indicator light is illuminated. If

the “AIR BAG 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 “AIR BAG 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.

1-1. For safe use

Exhaust gas precau-

tions

Harmful substance to the
human body is included in
exhaust gases if inhaled.

WARNING

Exhaust gases contain harmful

carbon monoxide (CO), which is

colorless and odorless. Observe

the following precautions.

Failure to do so may cause

exhaust gases to enter the vehicle

and may lead to an accident

caused by light-headedness, or

may lead to death or a serious

health hazard.

■

Important points while driving

●

Keep the back door closed.

●

If you smell exhaust gases in

the vehicle even when the back

door is closed, open the side

windows and have the vehicle

inspected at your Toyota dealer

as soon as possible.

■

When parking

●

If the vehicle is in a poorly venti-

lated area or a closed area,

such as a garage, stop the

hybrid system.

●

Do not leave the vehicle with

the hybrid system operating for

a long time.

If such a situation cannot be

avoided, park the vehicle in an

open space and ensure that

exhaust fumes do not enter the

vehicle interior.

●

Do not leave the hybrid system

operating in an area with snow

build-up, or where it is snowing.

If snowbanks build up around

the vehicle while the hybrid sys-

tem is operating, exhaust gases

may collect and enter the vehi-

cle.

■

Exhaust pipe

The exhaust system needs to be

checked periodically. If there is a

hole or crack caused by corro-

sion, damage to a joint or abnor-

mal exhaust noise, be sure to

have the vehicle inspected and

repaired by your Toyota dealer.

Riding with children

Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.



It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the shift lever, wiper
switch, etc.



Use the sliding door child-
protector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
(

operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.

WARNING

■

When children are in the vehi-

cle

Never leave children unattended

in the vehicle, and never allow

children to have or use the key.
Children may be able to start the

vehicle or shift the vehicle into

neutral. There is also a danger

that children may injure them-

selves by playing with the side

windows, the moon roof (if

equipped) or other features of the

vehicle. In addition, heat build-up

or extremely cold temperatures

inside the vehicle can be fatal to

children.

Table of contents

Points to remember

WARNING

■

When a child is riding

Observe the following precau-

tions.

Failure to do so may result in

death or serious injury.

●

For effective protection in auto-

mobile accidents and sudden

stops, a child must be properly

restrained, using a seat belt or

child restraint system which is

correctly installed. For installa-

tion details, refer to the opera-

tion manual enclosed with the

child restraint system. General

installation instructions are pro-

vided in this manual.

1-2. Child safety

For
safety and secu

rity

WARNING

●

Toyota strongly urges the use of

a proper child restraint system

that conforms to the weight and

size of the child, installed on the

rear seat. According to accident

statistics, the child is safer when

properly restrained in the rear

seat than in the front seat.

●

Holding a child in your or some-

one else’s arms is not a substi-

tute for a child restraint system.

In an accident, the child can be

crushed against the windshield

or between the holder and the

interior of the vehicle.

■

Handling the child restraint

system

If the child restraint system is not

properly fixed in place, the child or

other passengers may be seri-

ously injured or even killed in the

event of sudden braking, sudden

swerving, or an accident.

●

If the vehicle were to receive a

strong impact from an accident,

etc., it is possible that the child

restraint system has damage

that is not readily visible. In

such cases, do not reuse the

restraint system.

●

Make sure you have complied

with all installation instructions

provided by the child restraint

system manufacturer and that

the system is properly secured.

●

Keep the child restraint system

properly secured on the seat

even if it is not in use. Do not

store the child restraint system

unsecured in the passenger

compartment.

●

If it is necessary to detach the

child restraint system, remove it

from the vehicle or store it

securely in the luggage com-

partment.

When installing a child
restraint system to a front
passenger seat

For the safety of a child, install a
child restraint system to a rear
seat. When installing the child
restraint system to a front pas-
senger seat is unavoidable,
adjust the seat as follows and
install the child restraint system.



Raise the seatback as much
as possible.



Move the front seat fully rear-
ward.



If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.

When using a child
restraint system

WARNING

■

When using a child restraint

system

Observe the following precau-

tions.

Failure to do so may result in

death or serious injury.

●

Never install a rear-facing child

restraint system on the front

passenger seat even if the “AIR

BAG OFF” indicator light is illu-

minated. In the event of an acci-

dent, the force of the rapid

inflation of the front passenger

airbag can cause death or seri-

ous injury to the child if the rear-

facing child restraint system is

installed on the front passenger

seat.

●

A forward-facing child restraint

system may be installed on the

front passenger seat only when

it is unavoidable. A child

restraint system that requires a

top tether strap should not be

used in the front passenger seat

since there is no top tether strap

anchor for the front passenger

seat.

1-2. Child safety

For
safety and secu

rity

A child restraint system for a
small child or baby must itself be
properly restrained on the seat
with the lap portion of the
lap/shoulder belt.

■

Installing child restraint
system using a seat belt
(child restraint lock func-
tion belt)

Install the child restraint system
in accordance to the operation

WARNING

●

A forward-facing child restraint

system may be installed on the

front passenger seat only when

it is unavoidable. When install-

ing a forward-facing child

restraint system on the front

passenger seat, raise the seat-

back as much as possible,

move the seat to the rearmost

position, even if the “AIR BAG

OFF” indicator light is illumi-

nated.

If the head restraint interferes

with the child restraint system

installation and the head

restraint can be removed,

remove the head restraint.

●

Do not allow the child to lean

his/her head or any part of

his/her body against the door or

the area of the seat, front or rear

pillars, or roof side rails from

which the SRS side airbags or

SRS curtain shield airbags

deploy even if the child is

seated in the child restraint sys-

tem. It is dangerous if the SRS

side airbags and curtain shield

airbags inflate, and the impact

could cause death or serious

injury to the child.

●

When a booster seat is

installed, always ensure that the

shoulder belt is positioned

across the center of the child’s

shoulder. The belt should be

kept away from the child’s neck,

but not so that it could fall off the

child’s shoulder.

●

Use a child restraint system

suitable to the age and size of

the child and install it to the rear

seat.

●

If the driver’s seat interferes

with the child restraint system

and prevents it from being

attached correctly, attach the

child restraint system to the

right-hand rear seat.

●

Adjust the front passenger seat

so that it does not interfere with

the child restraint system.
