ing off in the vehicle to ensure
safety of driving.

Installing floor mats

WARNING

Observe the following precautions.

Failure to do so may cause the driver’s

floor mat to slip, possibly interfering with

the pedals while driving. An unexpect-

edly high speed may result or it may

become difficult to stop the vehicle. This

could lead to an accident, resulting in

death or serious injury.

■

When installing the driver’s floor mat

●

Do not use floor mats designed for

other models or different model year

vehicles, even if they are Lexus Genu-

ine floor mats.

●

Only use floor mats designed for the

driver’s seat.

●

Always install the floor mat securely

using the retaining hooks (clips) pro-

vided.

●

Do not use two or more floor mats on

top of each other.

●

Do not place the floor mat bot-

tom-side up or upside-down.

■

Before driving

●

Correct driving posture

WARNING

■

For safe driving

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

Do not adjust the position of the

driver’s seat while driving.

Doing so could cause the driver to lose

control of the vehicle.

●

Do not place a cushion between the

driver or passenger and the seatback.

A cushion may prevent correct pos-

ture from being achieved, and reduce

the effectiveness of the seat belt and

head restraint.

●

Do not place anything under the front

seats.

Objects placed under the front seats

may become jammed in the seat

tracks and stop the seat from locking in

place. This may lead to an accident

and the adjustment mechanism may

also be damaged.

●

Always observe the legal speed limit

when driving on public roads.

●

When driving over long distances, take

regular breaks before you start to feel

tired.

Also, if you feel tired or sleepy while

driving, do not force yourself to con-

tinue driving and take a break immedi-

ately.

Seat belts

Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle.

WARNING

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 seri-

ous injury.

■

Wearing a seat belt

●

Ensure that all passengers wear a seat

belt.

●

Always wear a seat belt properly.

●

Each seat belt should be used by one

person only. Do not use a seat belt for

more than one person at once, includ-

ing children.

●

Lexus recommends that children be

seated in the rear seat and always use

a seat belt and/or an appropriate child

restraint system.

●

To achieve a proper seating position,

do not recline the seat more than nec-

essary. The seat belt is most effective

when the occupants are sitting up

straight and well back in the seats.

●

Do not wear the shoulder belt under

your arm.

●

Always wear your seat belt low and

snug across your hips.

■

Pregnant women

Obtain medical advice and wear the seat

belt in the proper way. (



P.25)

Women who are pregnant should posi-

tion the lap belt as low as possible over

the hips in the same manner as other

occupants, extending the shoulder belt

completely over the shoulder and avoid-

ing belt contact with the rounding of the

abdominal area.

If the seat belt is not worn properly, not

only the pregnant woman, but also the

fetus could suffer death or serious injury

as a result of sudden braking or a colli-

sion.

■

People suffering illness

Obtain medical advice and wear the seat

belt in the proper way. (

If your seat belts cannot be fastened

securely because they are not long enough,

a personalized seat belt extender is avail-

able from your Lexus dealer free of charge.

WARNING

●

Inspect the seat belt system periodi-

cally. 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 cor-

rectly, immediately contact your Lexus

dealer.

●

Replace the seat assembly, including

the belts, if your vehicle has been

involved in a serious accident, even if

there is no obvious damage.

propriate handling may lead to incor-

rect operation.

Correct use of the seat belts

WARNING

■

Using a seat belt extender

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 seri-

ous injury.

●

Do not wear the seat belt 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, increasing

the risk of death or serious injury in the

event of an accident.

1-1. For safe use

To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.

To release the seat belt, press the
release button .

■

Emergency locking retractor (ELR)

The retractor will lock the belt during a sud-

den stop or on impact. It may also lock if you

lean forward too quickly. A slow, easy

motion will allow the belt to extend so that

you can move around fully.

■

Automatic locking retractor (ALR)

When a passenger’s shoulder belt is com-

pletely extended and then retracted even

slightly, the belt is locked in that position and

cannot be extended. This feature is used to

hold a child restraint system (CRS) firmly. To

free the belt again, fully retract the belt and

then pull the belt out once more. (

1-1. For safe use

For safety and security

The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle 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 preten-

sioner has been activated

If the vehicle is involved in multiple colli-

sions, the pretensioner will activate for the

first collision, but will not activate for the

second or subsequent collisions.

■

PCS-linked seat belt pretensioner con-

trol

If the PCS (Pre-Collision System) deter-

mines that the possibility of a collision with a

vehicle is high, the seat belt pretensioners

will be prepared to operate.

WARNING

■

Adjustable shoulder anchor

Always make sure the shoulder belt is

positioned across the center of your

shoulder. The belt should be kept away

from your neck, but not falling off your

shoulder. Failure to do so could reduce

the amount of protection in an accident

and cause death or serious injuries in the

event of a sudden stop, sudden swerve or

accident.

Seat belt pretensioners (front
seats and outboard rear seats)

WARNING

■

Seat belt pretensioners

●

Do not place anything, such as a cush-

ion, on the front passenger’s seat.

Doing so will disperse the passenger’s

weight, which prevents the sensor

from detecting the passenger’s weight

properly. As a result, the seat belt pre-

tensioner for the front passenger’s seat

may not activate in the event of a colli-

sion.

●

If the pretensioner has activated, the

SRS warning light will come on. In that

case, the seat belt cannot be used

again and must be replaced at your

Lexus dealer.

1-1. For safe use

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
severity 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 (infla-

tion) by hot gases.

●

A loud noise and white powder will be

emitted.

●

Parts of the airbag module (steering

wheel hub, airbag cover and inflator) as

well as the 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 Lexus Enform Safety Connect sub-

scribers, 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” but-

ton) and an agent will attempt to speak

with the occupants to ascertain the level

of emergency and assistance required. If

the occupants are unable to communi-

cate, the agent automatically treats the

call as an emergency and helps to dis-

patch the necessary emergency services.

(



P.54)

• An SRS airbag is deployed.

• A seat belt pretensioner is activated.

• The vehicle is involved in a severe

rear-end collision.

■

SRS airbag deployment conditions (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 corre-

sponding 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 following situa-
tions:
• 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 collision in which the

front of the vehicle “underrides”, or goes

under, the bed of a truck

●

Depending on the type of collision, it is

possible that only the seat belt preten-

sioners will activate.

●

The SRS front airbags for the front pas-

senger will not activate if there is no pas-

senger 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 unoccu-

pied.

■

SRS airbag deployment conditions (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 per-

1-1. For safe use

For safety and security

pendicular to the vehicle orientation at an

approximate speed of 12 - 18 mph [20 -

30 km/h]).

●

Both SRS curtain shield airbags may

deploy in the event of a severe side colli-

sion.

●

Both SRS curtain shield airbags will

deploy in the event of vehicle rollover.

●

Both SRS curtain shield airbags will

deploy in the event of a severe frontal col-

lision.

■

Conditions under which the SRS air-

bags may deploy (inflate), other than a

collision

The SRS front airbags and SRS curtain

shield airbags may also deploy if a serious

impact occurs to the underside of your

vehicle. 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 marginal.

●

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 generally

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, deploy-

ment 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 airbags

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 vehicle

body other than the passenger compart-

ment

●

Collision from the side at an angle

The SRS side airbags do not generally

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

1-1. For safe use

The SRS curtain shield airbags do not gen-

erally 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.

●

When to contact your Lexus dealer

In the following cases, the vehicle will

require inspection and/or repair. Contact

your Lexus dealer as soon as possible.

●

Any of the SRS airbags have been

inflated.

●

The front of the vehicle is damaged 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 surrounding

area is damaged or deformed, or the

vehicle was involved in an accident that

was not severe enough to cause the SRS

side and curtain shield airbags to inflate.

●

The pad section of the steering wheel,

dashboard near the front passenger air-

bag or lower portion of the instrument

panel is scratched, cracked, or otherwise

damaged.

●

The surface of the seats with the SRS side

airbag is scratched, cracked, or other-

wise damaged.

For safety and security

WARNING

■

SRS airbag precautions

Observe the following precautions

regarding the SRS airbags.

Failure to do so may cause death or seri-

ous injury.

●

The driver and all passengers in the

vehicle must wear their seat belts

properly.

The SRS airbags are supplemental

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,
placing 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 position in several
ways:
• Move your seat to the rear as far as

you can while still reaching the pedals

comfortably.

• 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 adjustable, tilt

it downward. This points the airbag

toward your chest instead of your head

and neck.

The seat should be adjusted as recom-

mended 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 con-

nected 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 passen-

ger are wearing the seat belt even

though the seat belt has not been con-

nected. In this case, the SRS front air-

bags 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 airbag also

deploys with considerable force, and

can cause death or serious injury

especially if the front passenger is very

close to the airbag. The front passen-

ger seat should be as far from the air-

bag as possible with the seatback

adjusted, so the front passenger 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.

Lexus strongly recommends that all

infants and children be placed in the

rear seats of the vehicle and properly

restrained. The rear seats are safer for

infants and children than the front pas-

senger seat. (



P.41)

1-1. For safe use

WARNING

●

Do not sit on the edge of the seat or

lean against the dashboard.

●

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 occupants

to hold items on their knees.

●

Do not lean against the door, the roof

side rail or the front, side and rear pil-

lars.

●

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 any-

thing against areas such as the dash-

board, steering wheel pad and lower

portion of the instrument panel.

These items can become projectiles

when the SRS driver, front passenger

and 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.

●

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.

1-1. For safe use

For safety and security

WARNING

●

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 air-

bags inflate as they may interfere with

inflation of the SRS airbags. Such

accessories may prevent the side air-

bags from activating correctly, disable

the system or cause the 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. Doing so can cause the

SRS airbags to malfunction.

●

Do not touch any of the component

parts immediately after the SRS air-

bags have deployed (inflated) as they

may be hot.

●

If breathing becomes difficult after the

SRS airbags have deployed, open a

door or window to allow fresh air in, or

leave the vehicle if it is safe to do so.

Wash off any residue as soon as possi-

ble to prevent skin irritation.

●

If the areas where the SRS airbags are

stored, such as the steering wheel pad

and front and rear pillar garnishes are

damaged or cracked, have them

replaced by your Lexus dealer.

●

Do not place anything, such as a cush-

ion, on the front passenger’s seat.

Doing so will disperse the passenger’s

weight, which prevents the sensor

from detecting the passenger’s weight

properly. As a result, the SRS front air-

bags for the front passenger may not

deploy in the event of a collision.

■

Modification and disposal of SRS air-

bag system components

Do not dispose of your vehicle or per-

form any of the following modifications

without consulting your Lexus dealer.

The SRS airbags may malfunction or

deploy (inflate) accidentally, causing

death or serious injury.

●

■

Front passenger occupant classifica-

tion system precautions

Observe the following precautions

regarding the front passenger occupant

classification system.

Failure to do so may cause death or seri-

ous 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 passenger seat.

1-1. For safe use

For safety and security

WARNING

●

Make sure the “AIR BAG OFF” indica-

tor light is not illuminated when using

the seat belt extender for the front pas-

senger seat. If the “AIR BAG OFF”

indicator light is illuminated, discon-

nect the extender tongue from the seat

belt buckle, and reconnect 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” indicator light is illumi-

nated, the SRS airbags for the front

passenger 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 equipment (e.g.

seatback pocket).

●

Do not put weight on the front passen-

ger seat by putting your hands or feet

on the front passenger 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 seatback with their legs.

●

Do not put objects under the front pas-

senger seat.

●

Do not recline the front passenger

seatback so far that it touches a rear

seat. This may cause the “AIR BAG

OFF” indicator 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 seatback as upright as

possible when the vehicle is moving.

Reclining the seatback excessively

may lessen the effectiveness of the

seat belt system.

●

If an adult sits in the front passenger

seat, the “AIR BAG ON” indicator light

is illuminated. If the “AIR BAG OFF”

indicator is illuminated, ask the passen-

ger 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 illumi-

nated, either ask the passenger to

move to the rear seat, or if that is not

possible, move the front passenger

seat fully rearward.

●

When it is unavoidable to install a for-

ward-facing child restraint system on

the front passenger seat, install the

child restraint system on the front pas-

senger seat in the proper order.

the SRS warning light may come on to

indicate a malfunction of the front pas-

senger occupant classification system.

In this case, contact your Lexus dealer

immediately.

●

Child restraint systems installed on the

rear seat should not contact the front

seatbacks.

●

Do not use a seat accessory, such as a

cushion and seat cover, that covers the

seat cushion surface.

●

Do not modify or replace the uphol-

stery of the front seat.

●

console box and front passenger seat.

Otherwise, the system may not detect

the front passenger properly, leading

to improper operation of the airbags.

●

Adjust the front passenger seat so that

the head restraint does not touch the

ceiling. If the head restraint is left in

contact with the ceiling, the system

may not detect the front passenger

properly, leading to improper opera-

tion of the airbags.

There is a malfunction in the system

: The system judges a person of adult size as an adult. When a smaller adult sits in the

front passenger seat, the system may not recognize him/her as an adult depending on
his/her physique and posture.

: In the event the front passenger is wearing a seat belt.

: In the event the front passenger does not wear a seat belt.

: For some children, child in seat, child in booster seat or child in convertible seat, the sys-

tem may not recognize him/her as a child. Factors which may affect this can be the phy-
sique or posture.

: Never install a rear-facing child restraint system on the front passenger seat. A for-

ward-facing child restraint system should only be installed on the front passenger seat
when it is unavoidable. (

Exhaust gas precautions

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

WARNING

Exhaust gases include harmful carbon

monoxide (CO), which is colorless and

odorless. Observe the following precau-

tions.

Failure to do so may cause exhaust gases

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 trunk lid closed.

●

If you smell exhaust gases in the vehi-

cle even when the trunk lid is closed,

open the windows and have the vehi-

cle inspected at your Lexus dealer as

soon as possible.

■

When parking

●

If the vehicle is in a poorly ventilated

area or a closed area, such as a

garage, stop the engine.

●

Do not leave the vehicle with the

engine on 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 engine running in an

area with snow build-up, or where it is

snowing. If snowbanks build up around

the vehicle while the engine is running,

exhaust gases may collect and enter

the vehicle.

■

Exhaust pipe

The exhaust system needs to be checked

periodically. If there is a hole or crack

caused by corrosion, damage to a joint

or abnormal exhaust noise, be sure to

have the vehicle inspected and repaired

by your Lexus dealer.

Riding with children

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



It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch etc.



Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the

(



P.93, 115)



Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.

WARNING

■

When children are in the vehicle

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

themselves by playing with the windows,

the moon roof (if equipped) or other fea-

tures of the vehicle. In addition, heat

build-up or extremely cold temperatures

inside the vehicle can be fatal to children.

Child restraint systems

Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.

Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child restraint
system to a rear seat. Be sure to fol-
low the installation method that is in
the operation manual enclosed with
the restraint system.

Table of contents

Points to remember

1-2. Child safety

tions for child restraint systems.



Use a child restraint system until the
child becomes large enough to
properly wear the vehicle’s seat belt.



Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.

■

Types of child restraint system installation methods

Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.

WARNING

■

When a child is riding

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

For effective protection in automobile

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 operation man-

ual enclosed with the child restraint

system. General installation instruction

is provided in this manual.

●

Lexus strongly urges the use of a

proper child restraint system that con-

forms 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 someone

else’s arms is not a substitute for a child

restraint system. In an accident, the

child can be crushed against the wind-

shield or between the holder and the

interior of the vehicle.

■

Handling the child restraint system

If the child restraint system is not prop-

erly fixed in place, the child or other pas-

sengers may be seriously injured or even

killed in the event of sudden braking, sud-

den swerving, or an accident.

●

If the vehicle were to receive a strong

impact from an accident, etc., it is pos-

sible 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 with

the child restraint system manufac-

turer and that the system is properly

secured.

●

Keep the child restraint system prop-

erly 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 trunk.

WARNING

■

When using a child restraint system

Observe the following precautions.

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” indi-

cator light is illuminated. In the event of

an accident, the force of the rapid infla-

tion of the front passenger airbag can

cause death or serious injury to the

child if the rear-facing child restraint

system is installed on the front passen-

ger seat.

●

A forward-facing child restraint system

may be installed on the front passen-

ger 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.

●

A forward-facing child restraint system

may be installed on the front passen-

ger seat only when it is unavoidable.

When installing a forward-facing child

restraint system on the front passenger

seat, adjust the seatback angle to the

most upright position, move the seat

fully rearward, and move the seat

height to the upper most position, even

if the “AIR BAG OFF” indicator light is

illuminated.

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

●

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 system. It is dangerous if the

SRS side and curtain shield airbags

inflate, and the impact could cause

death or serious injury to the child.

1-2. Child safety

For safety and security

A child restraint system for a small
child or baby must itself be properly

WARNING

●

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.

●

Follow all installation instructions pro-

vided by the child restraint system

manufacturer.

●

When securing some types of child

restraint systems in rear seats, it may

not be possible to properly use the

seat belts in positions next to the child

restraint without interfering with it or

affecting seat belt effectiveness. Be

sure your seat belt fits snugly across

your shoulder and low on your hips. If it

does not, or if it interferes with the

child restraint, move to a different posi-

tion. Failure to do so may result in

death or serious injury.

●

When installing a child restraint system

in the rear center seat, adjust both seat

cushions to the same position and

align both seatbacks at the same

angle. Otherwise, the child restraint

system cannot be securely restrained

and this may cause death or serious

injuries in the event of sudden braking,

sudden swerving or an accident.

●

If the seat is adjusted, reconfirm the

security of the child restraint system.

■

When installing a booster seat

To prevent the belt from going into ALR

lock mode, do not fully extend the shoul-

der belt. ALR mode causes the belt to

tighten only. This could cause injury or

discomfort to the child. (



P.26)

■

Do not use a seat belt extender

If a seat belt extender is used when

installing a child restraint system, the seat

belt will not securely hold the child
